Quick Answer: The best time to do the Manaslu Circuit Trek is autumn (September to November) and spring (March to May). October is the single best month offering crystal-clear skies, stable weather, and ideal Larkya La Pass (5,160m) crossing conditions. April is the best spring month, with rhododendron forests in full bloom and warmer daytime temperatures. Monsoon (June to August) is generally avoided. Winter (December to February) is only for experienced mountaineers Larkya La is frequently snowbound.

Ask ten Manaslu trekkers when they went, and nine will say October or April. Ask them which one they would choose again, and the answer is almost always split down the middle. Autumn trekkers love the crystal clarity. Spring trekkers love the colour. This guide does not just tell you which season is best, it tells you which season is best for you, with verified temperature data, month-by-month Larkya La Pass conditions, crowd levels, and a decision framework no competitor has built in one place.
Why Timing Matters More on the Manaslu Circuit Than Most Nepal Treks
The Manaslu Circuit is not a single-climate trek. It spans six distinct climate zones from tropical lowlands at Arughat (approximately 700m) to arctic conditions at Larkya La Pass (5,160m). A warm, sunny morning in the Budi Gandaki Valley can become a blizzard at the pass within the same afternoon. Unlike lower-altitude treks where a bad weather day means a wet walk, a wrong weather window at Larkya La can close the pass entirely.
This matters more on Manaslu than on most other Nepal treks for a specific logistical reason: the circuit is in a Restricted Area. You cannot simply abandon the route and take a road back. Once you are committed to the upper circuit, the crossing must happen and if conditions close the pass, your options are limited and expensive.
Timing also affects teahouse availability, crowd levels, trail conditions, permit queues, wildlife sightings, and access to local cultural festivals. Choosing the right month is the most important planning decision you will make about this trek before you book anything else.
Quick Season Overview
| Season | Months | Overall Rating | Larkya La Passable | Crowds | Best For |
| Autumn | September to November | Outstanding | Yes , best conditions | High in October | Views, photography, all trekkers |
| Spring | March to May | Outstanding | Yes , good conditions | Medium | Nature lovers, photographers, wildlife |
| Monsoon | June to August | Limited | Risky | Very low | Experienced trekkers only |
| Winter | December to February | Difficult | Often closed | Very low | Expert mountaineers only |
Autumn: The Best Season for the Manaslu Circuit Trek (September to November)
Autumn is the undisputed peak season for the Manaslu Circuit and the choice of most first-time trekkers for good reason. The monsoon clears, the air dries out, and the mountain views that define this route become genuinely extraordinary. The three months within the season, however, are meaningfully different from one another.
September Green Valleys, Clearing Skies
September sits at the boundary between monsoon and autumn. The lower sections of the circuit Soti Khola, Jagat, Deng still carry the moisture of the outgoing monsoon. Trails are intensely green, waterfalls are roaring, and the forests along the Budi Gandaki are lush in a way no other month delivers. For photographers chasing colour and texture rather than pure mountain clarity, September is one of the most rewarding months on the circuit.
By mid-September, skies begin clearing significantly above 3,000m. Larkya La Pass is generally passable for prepared trekkers from late September onward, though some residual mud and wet rock on the lower approach sections require careful footing.
Crowd levels are low to medium, one of the best months if you want post-monsoon freshness without the peak-season congestion of October.
Daytime temperatures in the lower valleys range from 15 to 22°C. At Samagaon (3,530m) and Samdo, expect 5 to 12°C during the day and -2 to 5°C at night. All teahouses are open along the full route.
October: The Single Best Month on the Circuit
October is the undisputed peak month for the Manaslu Circuit universally agreed across guides, operators, and experienced trekkers. The post-monsoon air is crystal clear, and visibility from Samagaon to the Manaslu summit (8,163m) on a calm October morning is the kind of view that appears on the covers of trekking magazines.
Temperatures across the circuit are close to ideal. The valleys are warm enough to be comfortable without the summer heat, and the high altitude sections are dry and stable. Larkya La Pass crossing conditions in October are the most reliable of any month: stable high-pressure systems, minimal snow accumulation, and the broadest safe crossing windows of the year.
The one significant planning implication is accommodation. Teahouses at Samagaon, Samdo, and Larkya Phedi fill quickly in October. Book accommodation three to four months in advance for peak October travel. Permit checkpoint queues also add time to mornings and start crossing days early.
Daytime temperatures in the lower valleys are 15 to 20°C. At Samagaon, expect 5 to 12°C days and 0 to -5°C nights. At the Larkya La dawn crossing (typically 3:00 to 5:00am), temperatures are around -10 to -12°C with wind chill making the felt temperature considerably lower.
November Crisp Air, Thinning Crowds, Colder Nights
November is autumn’s quieter second act and an excellent choice for trekkers who want October’s views without October’s crowds. Crowds thin noticeably after the first week of November. Mountain views remain excellent, the air stays dry and clear, and the autumn foliage in the lower valleys adds a different kind of colour to the landscape.
Temperatures drop meaningfully. Proper down layers and a sleeping bag rated to at least -10°C are essential from Samagaon upward. Larkya La is still passable in early to mid-November; by late November, snow begins building and crossings require more care and experience.
Daytime temperatures in the lower valleys are 10 to 15°C. At Samagaon, expect 3 to 8°C days and -5 to -10°C nights. Some higher teahouses at Larkya Phedi begin closing by late November.
November suits experienced trekkers who want excellent visibility, fewer people, and are comfortable with colder conditions. It also suits budget-conscious trekkers, as accommodation becomes easier to find and some operators offer late-season pricing.
Spring: The Second-Best Season (March to May)
Spring is genuinely outstanding on the Manaslu Circuit and not merely a consolation prize to autumn. The rhododendron forests that cover the mid-altitude sections of the route are some of the finest in Nepal, and April specifically produces a visual experience of pink, red, and white blooms against snow-capped peaks that autumn cannot replicate.
March: Quiet Trails, Challenging High Pass
March opens the spring season. The lower and mid-altitude valley sections begin warming and showing new growth. Rhododendrons begin blooming from mid-March in the Jagat, Deng, and Namrung areas, with earlier colour at lower elevations and later blooms progressing upward as the month continues.
Larkya La Pass can still carry significant snow in early to mid-March. Crampons and ice axe may be required, and the crossing is best attempted only by experienced trekkers comfortable with winter conditions. By late March, conditions improve noticeably.
Crowd levels are very low. March is one of the most solitary months on the entire circuit ideal for trekkers who want a genuine wilderness experience without sharing it with dozens of other groups.
Daytime temperatures in the lower valleys are 12 to 18°C. At Samagaon, expect 2 to 8°C days and -5 to -10°C nights. Some higher teahouses are just reopening after winter and may not be fully stocked.
April: The Best Spring Month
April is the spring equivalent of October, the single best month in the spring season for most trekkers. Rhododendron forests at Jagat, Deng, Namrung, and Lho are in peak bloom. The combination of dense flowering forest and snow-capped Manaslu in the background is unique to this month and has no equivalent in any other season on this route.
Larkya La Pass conditions in April are excellent. Winter snow has largely melted by mid-April, pre-monsoon weather systems are stable, and crossing windows are reliable. All teahouses are open and fully operational.
Crowd levels are medium noticeably busier than March but significantly quieter than October. The balance of conditions, colour, and manageable crowds makes April the most consistently recommended month for nature-focused trekkers.
Daytime temperatures in the lower valleys are 15 to 22°C. At Samagaon, expect 8 to 15°C during the day and -2 to 2°C at night. At the Larkya La dawn crossing, temperatures range from -8 to -5°C.
For those considering photography as a primary focus, April is the strongest month on the circuit. The rhododendron and mountain combination appears nowhere else with this density and at this altitude.
May: Warmer Days, Pre-Monsoon Haze
May sees lower sections of the circuit become noticeably warmer and more humid. The high-altitude sections remain excellent. Larkya La is reliably clear and snow-free throughout May. Pre-monsoon clouds begin building in the lower valleys during afternoons, though morning visibility remains strong.
Crowd levels are low to medium. Most spring trekkers have either already completed the circuit or are waiting for autumn. Daytime temperatures in the lower valleys reach 20 to 28°C, warm for the river sections but comfortable at altitude. At Samagaon, expect 12 to 18°C days and 3 to 8°C nights.
May suits budget-conscious trekkers who can work around afternoon cloud cover in the lower sections and those who prefer warmth in the valley stages.
Larkya La Pass: Month-by-Month Crossing Conditions
Every trekker must cross the Larkya La Pass (5,160m) to complete the Manaslu Circuit. It is the highest point of the route, the most weather-dependent moment, and the section where conditions vary most dramatically by month. No other single factor determines the safety and success of the circuit more than crossing day conditions at this pass.
| Month | Pass Condition | Snow Level | Crossing Difficulty | Recommendation |
| January | Frequently closed | Deep snow and ice | Extreme | Mountaineering gear essential; not recommended |
| February | Risky | Heavy snow | Very hard | Not recommended for standard trekking |
| March | Challenging | Moderate to heavy snow | Hard | Crampons required; experienced trekkers only |
| April | Good | Light snow or clear | Moderate | Recommended one of the two best months |
| May | Excellent | Usually snow-free | Easy to moderate | Reliable; ideal for first-timers |
| June | Risky | Pre-monsoon instability | Hard | Afternoon storms; not recommended |
| July | Avoid | Monsoon instability | Dangerous | High accident risk |
| August | Avoid | Monsoon conditions | Very hard | Not recommended |
| September | Fair to good | Clearing post-monsoon | Moderate | Late September is good; early is riskier |
| October | Best | Minimal | Easy to moderate | Best month highest safety margin |
| November | Good (early) | Increasing from mid-month | Moderate to hard | Fine until mid-November; caution late |
| December | Challenging | Snow building | Hard | Early December only; avoid late December |
One rule applies regardless of month: start the Larkya La crossing before 5:00 to 6:00am. Afternoon clouds close in consistently throughout the trekking season, and the pass becomes significantly more hazardous once the weather turns. Above 5,000m, conditions can shift in under an hour. Your guide’s judgment on crossing day is the final word.
Monsoon Season: Should You Trek Manaslu in June to August?
The standard advice across most trekking websites is to avoid monsoon on the Manaslu Circuit. That is correct for the lower sections and incomplete for the upper valley. The nuanced picture is worth understanding before you dismiss June to August entirely.
The lower Budi Gandaki sections from Soti Khola to Jagat and beyond are genuinely challenging in monsoon conditions. Landslide risk is real on these sections. Leeches are prolific. River crossings become more dangerous with higher water levels. Trail surfaces become slippery on the steeper sections.
What changes above 3,000m is meaningful: the upper Manaslu valley sits in a partial rain shadow formed by the Himalayan range. Samagaon, Samdo, and the areas approaching Larkya La receive significantly less monsoon rainfall than the lower sections. Trekkers who can navigate the lower section carefully or time their arrival in the upper valley for a period of relative stability will find a surprisingly viable trekking environment in July and August, with lush green landscapes, near-empty teahouses, and mountains that clear occasionally in the mornings.
Larkya La Pass itself is the limiting factor in monsoon. Unpredictable afternoon storms and wet rock conditions make the crossing genuinely risky in June through August. This is where most experienced trekkers who consider the monsoon draw their line.
Late August and early September occupy a transitional zone that experienced, flexible trekkers with contingency days built in can navigate well. For everyone else: wait for the autumn clearing.
For the difficulty context that informs monsoon planning decisions, Manaslu Circuit Trek difficulty covers the route’s physical demands by section.
Winter Trekking: December to February
Winter on the Manaslu Circuit is for experienced mountaineers, not general trekkers. The distinction matters.
Early December the first two weeks remain viable for well-prepared trekkers who arrive with the right gear and realistic expectations. Skies are crystal clear, mountain views are exceptional, trails are very quiet, and pricing is at its lowest. The circuit can be completed in early December by trekkers carrying proper cold-weather equipment and with solid high-altitude experience.
From late December through February, the picture changes fundamentally. Larkya La Pass can receive deep snow and ice, making the crossing technically demanding at best and impossible at worst. Teahouses at Larkya Phedi and sometimes Samdo close for the winter. Temperatures at Samagaon drop to approximately -5°C during the day and -15°C or lower at night. At the Larkya La crossing in the pre-dawn hours, temperatures can reach -20°C with significant wind chill.
What winter offers to those equipped for it: absolute solitude, stunning clear skies, an expedition-style atmosphere, and the knowledge that you are seeing a side of this route that very few trekkers ever experience.
What it demands: mountaineering-grade cold weather gear, crampons, ice axe, camping capability if teahouses are closed, and extensive prior experience at high altitude in winter conditions.
January and February should not be attempted on the full circuit without preparation that goes significantly beyond standard trekking equipment.
Month-by-Month Temperature Table
| Month | Valley Day Temp | Valley Night Temp | Samagaon Day | Larkya La at Dawn | Season |
| January | 5–10°C | -2 to 2°C | -5°C | -20°C | Winter |
| February | 8–14°C | 0–4°C | -3°C | -15°C | Winter |
| March | 12–18°C | 2–6°C | 2–8°C | -10°C | Spring |
| April | 15–22°C | 5–10°C | 8–15°C | -8 to -5°C | Spring |
| May | 20–28°C | 10–14°C | 12–18°C | -5°C | Spring |
| June | 22–30°C | 14–18°C | 14–20°C | 0 to 5°C | Monsoon |
| July | 24–31°C | 16–20°C | 15–20°C | 0 to 5°C | Monsoon |
| August | 23–30°C | 15–18°C | 14–18°C | 0°C | Monsoon |
| September | 18–24°C | 8–12°C | 8–15°C | -5°C | Autumn |
| October | 15–22°C | 5–8°C | 5–12°C | -12°C | Autumn |
| November | 10–16°C | 0–5°C | 0–6°C | -15°C | Autumn |
| December | 6–12°C | -2 to 2°C | -5 to 0°C | -20°C | Winter |
Larkya La dawn temperatures are estimated for the standard 3:00 to 5:00am crossing start time. Wind chill at the pass can make the felt temperature considerably lower than the air temperature particularly in October and November when katabatic winds are common at altitude.
Crowd Levels by Month When to Go for Solitude

| January | Empty | Expedition-only atmosphere |
| February | Very quiet | Almost deserted |
| March | Light | Peaceful; mostly experienced trekkers |
| April | Moderate | Active but not crowded |
| May | Light to moderate | Good balance of activity and quiet |
| June | Very quiet | Solitude plus mud |
| July | Almost empty | Monsoon; very few trekkers |
| August | Quiet | Clearing toward September |
| September | Light to moderate | Excellent trade-off month |
| October | Peak and busy | Book well in advance; teahouses fill quickly |
| November | Moderate (early) to light (late) | Crowds thin noticeably mid-month |
| December | Quiet | Last viable month before full winter |
Which Season Is Right for You?
Choose October if you: Are doing the Manaslu Circuit for the first time and want the most reliable experience. I want the clearest mountain views and most stable weather window of the year. Are a photographer focused on mountain clarity and panoramic shots. Are comfortable planning and booking well ahead and do not mind sharing the trail.
Choose April if you: Love colour and want the rhododendron forest experience that October cannot offer. Prefer slightly warmer temperatures in the valley sections. Want good Larkya La conditions with noticeably fewer people than October. Are a wildlife or nature photographer April is the most active month for birds, flowers, and the occasional red panda or Himalayan tahr sighting.
Choose late September if you: Want the best of both seasons post-monsoon lush green landscapes combined with clearing mountain skies. Want good conditions without peak-season crowds. Have schedule flexibility and can monitor weather forecasts before departure.
Choose early November if you: Prefer solitude over crowds and have good cold-weather experience. Want to avoid peak pricing while keeping excellent mountain visibility. Are prepared for colder nights and are carrying appropriate gear for -10°C or below at altitude.
Choose monsoon (July to August) only if you: Are an experienced trekker comfortable with landslide awareness and leech management. Are chasing budget pricing and absolute trail solitude. Have a flexible itinerary with buffer days built in. Understand clearly that Larkya La will be risky and may not be crossable.
Choose early December only if you: Are an experienced high-altitude trekker with full mountaineering cold-weather gear. Value solitude and clear skies above all other factors. Have winter camping capability in case teahouses are closed in the upper valley.
Festivals and Cultural Events : Aligning Your Trek for Cultural Depth
| Festival | Community | Typical Timing | Trek Zone |
| Lhosar (Tibetan New Year) | Sherpa and Tibetan Buddhist | February to March | Samagaon, Samdo, Lho village |
| Saga Dawa (Buddha’s birthday) | Buddhist | May to June (full moon) | Monasteries throughout the upper route |
| Dashain | Hindu (lower villages) | September to October | Arughat, Gorkha, lower Budi Gandaki |
| Tihar / Deepawali | Hindu | October to November | Lower villages on the approach |
| Manaslu Expedition Season | Mountaineering teams | Spring (March to May) | Samagaon Base Camp area |
The September to October window combines the tail of the Dashain season in the lower villages with peak Buddhist monastery activity in the upper circuit. Lho village during Lhosar in late February or early March offers one of the most authentic cultural experiences on the entire route: village celebrations with traditional dance, ceremony, and food. Ask your guide whether your timing aligns with this festival if you are trekking in the March window.
Photography Guide: Best Month for Every Shot
| Photography Goal | Best Month | Why |
| Rhododendron forests with mountain backdrop | April | Peak bloom against snow-capped Manaslu unique to this month |
| Crystal mountain panoramas | October | Post-monsoon clarity; best visibility of the year |
| Golden autumn foliage | Early November | Autumn leaf colour in lower and mid-altitude valleys |
| Monastery life and monks | March to April or October | Both seasons see regular monastery activity |
| Green valley and waterfalls | September | Post-monsoon lushness at its peak |
| Milky Way and night sky | October to November | Dry, clear, dark skies at altitude |
| Wildlife red panda and Himalayan tahr | April to May | Active breeding season; more visible at forest edges |
| Sunrise over Manaslu from Samagaon | October | Best clarity; optimal angle of morning light |
Manaslu Circuit vs Annapurna Circuit – Timing Comparison
| Factor | Manaslu Circuit | Annapurna Circuit |
| Best seasons | October and April | October and April |
| October crowd levels | Moderate to high | Very high |
| Highest pass | Larkya La (5,160m) best in October and April | Thorong La (5,416m) best in October and May |
| Spring rhododendrons | Outstanding in April | Good in April |
| Teahouse density | Lower advance booking needed | Very high throughout |
| Winter viability | Very limited Larkya La closes | Partially viable on lower sections |
| Monsoon rain-shadow trekking | Upper valley viable for experienced trekkers | Mustang side viable |
The most practically useful comparison for planning purposes: Manaslu in October is meaningfully less crowded than the Annapurna Circuit in October. If avoiding teahouse queues and permit checkpoint congestion matters to you, and both circuits are on your list, Manaslu in October delivers the same quality of mountain experience with a noticeably quieter trail. The Manaslu Circuit Trek itinerary gives the full route breakdown for planning purposes.
Practical Tips for Timing Your Trek
Book Kathmandu accommodation and flights early for October. October is the single busiest month in Nepal’s trekking calendar across all regions. Flights from Kathmandu to Arughat or Gorkha, and accommodation in Kathmandu before and after the trek, should be arranged three to four months in advance.
Get permits through your agency. The Manaslu Restricted Area Permit, MCAP (Manaslu Conservation Area Permit), and ACAP permits are all available year-round. Your trekking agency handles these as part of the booking process. For current permit costs and requirements, the Manaslu Circuit Trek cost page covers the full fee breakdown.
Build a weather buffer day at Larkya Phedi. This is the single most practical advice for any Manaslu Circuit trekker regardless of season. One buffer day at the camp before the pass allows you to wait out a poor weather window without abandoning the crossing entirely. The difference between a successful crossing and a failed one is often one extra day of patience.
Check the Nepal Meteorological Forecasting Division forecast within five days of your crossing. Weather forecasts for the Himalayan region become reasonably reliable within a five-day window. Checking the forecast at mfd.gov.np before committing to your crossing day is a simple step that adds a meaningful safety margin.
Pack by season, not by general advice. October requires a warm down jacket rated to at least -15°C, a good fleece mid-layer, thermal base layers, and a waterproof outer shell. April requires lighter layering for the valley sections plus the same warm layers for the pass crossing. The temperature differential between the valley and the pass on a single day can be 25°C or more; versatile layering is not optional.
Time Your Trek Right and the Manaslu Will Reward You
There is no universally wrong time for the Manaslu Circuit but there are times that suit different trekkers and times that demand experience and equipment far beyond what most people carry.
October and April are the gold standard: reliable, beautiful, and safe for most fitness and experience levels. Late September and early November offer the same quality with fewer people on the trail, an excellent choice for trekkers who plan carefully and are comfortable with slightly less predictable conditions. Monsoon and winter are for experienced adventurers who understand exactly what they are committing to before they leave home.
The Manaslu Circuit remains one of Nepal’s greatest journeys, remote, culturally rich, and physically demanding in a way that makes every cleared weather window feel earned. Timing it right does not guarantee an unforgettable trip. But it makes one significantly more likely.
Frequently Asked Questions Best Time for the Manaslu Circuit Trek
What is the best time to do the Manaslu Circuit Trek?
October and April are the best months. October offers the clearest mountain views and most stable Larkya La Pass conditions. April combines good weather with spectacular rhododendron blooms. Both months have fully open teahouses and reliable trail conditions throughout the circuit.
Can you do the Manaslu Circuit in winter?
Early December is feasible for well-prepared, experienced trekkers. January and February are not recommended for standard trekking. Larkya La is frequently blocked by deep snow, many teahouses close, and night temperatures at altitude can reach -15°C or lower. Full mountaineering cold-weather equipment is required.
Is it safe to trek Manaslu during monsoon?
The full circuit is not recommended in peak monsoon due to landslide risk on the lower sections and dangerous Larkya La conditions. The upper valley sits in a partial rain shadow and is more viable. Experienced trekkers with flexible itineraries can consider late August. Late September is when conditions improve significantly for most trekkers.
What is the best month for the Larkya La Pass crossing?
October is the best month with stable weather, minimal snow, and wide safe crossing windows. April is the best spring option. Start the crossing before 5:00 to 6:00am regardless of month, as afternoon clouds and wind make the pass more hazardous.
How crowded is the Manaslu Circuit in October?
October is peak season and the busiest month. Teahouses at Samagaon, Samdo, and Larkya Phedi fill quickly. Book accommodation well in advance. Trekkers who prefer solitude should consider late September or early November for similar conditions with fewer people.
When are the rhododendrons in bloom on the Manaslu Circuit?
Peak bloom is from late March through April. The forests around Jagat, Deng, Namrung, and Lho are particularly spectacular, with red, pink, and white varieties flowering simultaneously against a backdrop of snow-capped peaks.
Which is better for Manaslu, spring or autumn?
Both are excellent. Autumn (especially October) offers the clearest mountain views and most stable conditions ideal for first-timers and mountain photographers. Spring (especially April) offers rhododendron blooms, warmer valley temperatures, and fewer crowds ideal for nature lovers and those who want more colour on the trail.
What temperature should I expect in October?
Lower valley daytime temperatures are 15 to 20°C. At Samagaon (3,530m), expect 5 to 12°C days and 0 to -5°C nights. At the Larkya La crossing (3:00 to 5:00am start), air temperature is approximately -10 to -12°C. Wind chill makes it feel significantly colder. A down jacket, fleece, and thermal base layers are minimum requirements for the crossing.
