Weather and temperature in the Manaslu region vary throughout the year, and the change becomes more extreme above 5,000 meters. Additionally, the Manaslu trek weather and temperature shift dramatically depending on season, elevation, and proximity to Larkya La Pass (5,106 m). This guide explains Manaslu trek weather by month, so you can understand how conditions shift and what to expect at different stages of the route.
The best time for Manaslu trek is either the spring (March to May) or the autumn (September to November). Generally, trekkers choose these periods because they offer the most dependable conditions. They are known for stable weather, moderate temperatures, and clear visibility. For example, spring features blooming rhododendron forests, and the days are warmer. Autumn, on the other hand, brings strong, post-monsoon clarity along with cool, dry air.
Winter (December to February) means sub-zero temperatures and heavy snowfall. As a result, high passes such as Larkya La become harder to cross and carry a greater risk. The monsoon season (June to August) is the least suitable time for trekking. During this period, rain makes the trail slippery, raises landslide risk, and often hides the mountain views behind thick clouds.
If you are not sure about the right time for the Manaslu trek, choose the month that fits your comfort, skill level, and objectives. Ultimately, whether you choose the standard 15-day Manaslu Circuit Trek or a budget-friendly 12-day option, picking the right season makes all the difference for safety, trail conditions, and the overall experience.

Manaslu Trek Weather by Elevation
- Below 2,000 m (Machha Khola): Generally warm and humid during monsoon, while spring and autumn feel mild and comfortable for walking.
- 2,000 m to 3,500 m (Jagat to Namrung): Moderate temperatures; as a result, cooler nights begin to set in.
- 3,500 m to 4,500 m (Samagaun / Samdo): Sub-zero nights are common outside peak spring and autumn. At these elevations, it’s important to understand the symptoms explained in our Manaslu altitude sickness guide.
- Above 5,000 m (Larkya La Pass): Extreme wind chill, rapid weather shifts, and significantly colder real-feel temperatures regardless of season.
Manaslu Trek Weather by Month
The Manaslu region experiences distinct weather shifts from one month to the next. Depending on the time of the year, you might be navigating the icy winter crossings of the Larkya La Pass. Alternatively, you could be trekking under clear autumn skies. Likewise, there is a chance to move through blooming spring forests.
Each month presents unique trail conditions in the Manaslu. For this reason, understanding the Manalsu trek weather by month is the most effective way to prepare your gear and choose the right trekking season.
January (Winter: Cold and Snowy)
January is officially the coldest month of the year. So, if you’re thinking of the Manaslu trek in January, you’re seeing the area at its most natural and quiet. It is a serious physical challenge. In fact, January reflects the harsh side of Manaslu in winter, especially near high passes.
The Weather
- Daytime: -2°C and 6°C. If the sun is out, it’s manageable, but the moment it drops behind a peak, the temperature plunges.
- Nighttime: -15°C to -20°C. You’ll need a sleeping bag that can withstand those sub-zero temperatures, or you won’t be able to sleep at all.
The Terrain
Above 3,500 meters, the landscape turns into a total whiteout. Although it looks like a postcard, it makes hiking significantly harder.
- Larkya La Pass: This pass can become inaccessible. Heavy snowfall can cover the trails, and therefore navigation is not easy without an experienced guide.
- Trail Surfaces: The paths turn into sheets of ice. As a result, a single wrong can lead to a serious accident. This is especially true if you aren’t used to using crampons while navigating frozen terrain in high altitudes.
Gear and Experience
- Essential Kit: You’ll need heavy-duty down jackets, thermal base layers, insulated boots, and professional-grade gloves. For a detailed breakdown, see our full packing list for the Manaslu trek.
- The Reward: If you are experienced and well-prepared, you get a version of Manaslu that almost no one else sees — total silence, no crowds, and unmatched snowy vistas.
Final Words: January offers solitude to those who reach Manaslu. However, the extreme cold and possible pass closures make it a demanding experience. It is, however, intended for winter hikers who are prepared.
February (Late Winter: Cold but Clear)
February is still cold, yet it offers the clearest views of the year. While the extreme storms of January subside, the landscape remains locked in ice. Therefore, the Manaslu trek weather in February demands technical preparation and a high tolerance for sub-zero nights.
The Weather
- Daytime: 0°C to 8°C. The sun provides genuine warmth during hiking hours, but the wind remains bitingly cold.
- Nighttime: -10°C and -18°C. Thermal layers are mandatory to survive the nights in unheated teahouses.
The Terrain
Snow cover is still heavy at high altitudes. Nevertheless, the lack of fresh blizzards makes the path more predictable than in mid-winter.
- Larkya La Pass: Crossing this pass becomes more possible compared to January, as favorable weather windows are open for a longer duration. However, you will still be trekking through deep, lingering snowpack that requires strong navigation skills.
- Trail Surface: Snow melts slightly in the February afternoon, and it turns into slick black ice by morning. Thus, to walk on such a trail, high-traction footwear and microspikes are essential.
Gear and Experience
- Essential Kit: Waterproofing is the priority in the February Manaslu trek. Thus, you need insulated boots and gaiters to handle slushy afternoon trails, alongside a -20°C rated sleeping bag.
- The Reward: The total atmosphere is clear. The February air is crisp and dust-free, and in addition to that, the mountain views are at their clearest. Also, you will likely have the entire circuit to yourself.
Final Words: If you can manage the freezing nights, you get a pristine, crowd-free Himalayan experience that is impossible to find in the spring or autumn.
March (Spring: Cool and Clear)
If you are planning your Manaslu trek in March weather, also expect improving trail conditions with lingering snow at higher elevations.
The Weather
Days become noticeably more comfortable.
- Daytime: 4°C to 12°C. When the sky is clear, trekking feels pleasant, especially in the lower valleys where the sun carries real warmth.
- Nighttime: -6°C to -12°C at higher elevations. It still freezes at higher elevations. Thus, warm layers remain important.
The Terrain
Lower sections of the trail start drying out as the snow melts. As a result, walking becomes easier and less technical during this time of the year.
- Larkya La Pass: It is generally accessible, but early crossing of the pass in early March can still involve snowfields and icy stretches. Nonetheless, conditions depend heavily on recent snowfall.
- Trail Surface: Most sections of the path below 3,000 meters are dry and easy to walk on. But above that, you may still find patches of snow and firm ice remaining.
Gear and Experience
- Essential Kit: A properly insulated sleeping bag for freezing nights, flexible layering you can add or remove throughout the day, and microspikes for higher elevations where snow lingers.
- The Reward: You get wide-open mountain views and noticeably fewer trekkers than in April. Moreover, the lower sections of the trail witness the first touches of color as rhododendrons begin to bloom.
Final Words: The Manaslu trek weather in March is calm, clear, and beautifully balanced — just be ready for those cold evenings once the light fades.
April (Spring: Pleasant and Colorful)
The Manaslu region truly settles into the spring season in April. For many trekkers, this is one of the most enjoyable months to be on the circuit. This is because April showcases comfortable Manaslu spring temperature conditions across most elevations.
The Weather
- Daytime: 6°C to 16°C. Mornings are cool, and afternoons are ideal for hiking. At lower elevations, it can even feel warm during the afternoon.
- Nighttime: -2°C to -8°C at higher altitudes. Even in peak spring, nights above 3,500 meters remain cold, so warm layers are still necessary.
The Terrain
Most of the winter snow has cleared from lower- and mid-elevation trails. As a result, walking conditions improve significantly compared to early March.
- Larkya La Pass: In April, the pass is usually open and far more predictable than in winter. However, you may still encounter a few small patches of snow near the top.
- Trail Surface: Most of the trail feels dry and solid underfoot. Therefore, daily walking feels steady and comfortable.
Gear and Experience
- Essential Kit: Light layers you can adjust through the day, strong sun protection, and a reliable sleeping bag for colder nights higher up.
- The Reward: Rhododendrons burst into color, the mountains look crisp against clear skies, and the whole trail feels vibrant and alive.
Final Words: April truly shows spring at its finest — bright landscapes, stable weather, and days that are simply enjoyable to trek.
May (Spring: Warm and Mostly Dry)
May feels relaxed on the Manaslu trail. The sharp chill of early spring is gone, and the days are longer and warmer — the highlights of the May Manaslu trek weather. Mornings are cool and fresh. However, by midday, you’ll likely be hiking in just a base layer under the bright Himalayan sun.
The Weather
- Daytime: 10°C to 20°C. Lower down, it can feel properly warm, especially on exposed sections.
- Nighttime: Around 0°C to -5°C higher up. Cold, yes — but no longer biting the way it is in March.
The Terrain
By now, most of the winter snow has melted away.
- Larkya La Pass: Usually clear and uncomplicated unless there’s been a rare late snowfall. Crossings tend to be steady and predictable.
- Trail Surface: Dry and firm for the most part. In the lower valleys, you might notice a bit of dust as the month goes on.
Gear and Experience
- Essential Kit: Breathable layers for warm afternoons, good sunscreen, and a sleeping bag warm enough for cold nights at altitude.
- The Reward: Comfortable trekking days, bright green hillsides, and a sense that the mountains are fully open for the season.
Final Words: May is warm enough to enjoy the journey and cool enough to trek comfortably.
June (Early Monsoon: Warm with Occasional Rain)
June marks the beginning of the monsoon shift in Manaslu. The change isn’t immediate, but gradually, you can feel the air getting heavier as the month progresses.
The Weather
- Daytime: 12°C to 22°C. The weather is warm and often cloudy, especially in the afternoons.
- Nighttime: 2°C to 8°C. Nights are milder than spring, even at higher elevations.
Rain usually arrives in bursts rather than all day, with clearer mornings and wetter afternoons being the features of the Manaslu trek weather.
The Terrain
Lower trails become damp and occasionally muddy. Forest sections feel lush and thick.
- Larkya La Pass: Rainfall is lighter at higher altitudes; however, clouds can limit visibility.
- Trail Surface: Slippery in places, especially below 3,000 meters.
Gear and Experience
- Essential Kit: Waterproof jacket and pants, pack cover, trekking poles, quick-dry layers, and leech protection for lower forests.
- The Reward: The hills turn green, and the region feels fresh. The rivers get back to life with monsoon rains.
Final Words: June isn’t a terrible time to be on the Manaslu trail, provided that you are properly prepared for monsoon challenges. If you have packed proper rain gear and flexible clothing, the month can feel quiet and rewarding in its own way.
July (Monsoon: Rainy but Scenic)
July is the peak of the Manaslu monsoon season. If you choose this month, you should expect rain to be part of your daily routine rather than an occasional interruption.
The Weather
- Daytime: 14°C to 24°C. The days are warm, and it is noticeably humid in the lower regions.
- Nighttime: 4°C to 10°C. The temperatures are comfortable, despite the frequent damp conditions.
Rainfall is frequent, especially in the afternoons and evenings. Mornings tend to get cloudy, with showers building later in the day.
The Terrain
Lower sections of the trail often turn muddy and slippery. Even the forested areas are damp. Meanwhile, small streams can swell after heavy rain, creating a beautiful view.
- Larkya La Pass: This part of the trail receives less rainfall than the valleys. Yet the cloud cover is present and often limits visibility. Nonetheless, mountain views are not guaranteed in July — a drawback of the Manaslu trek weather.
- Trail surfaces: Trekkers need to walk carefully because mud builds up in forest sections. Likewise, steep stretches feel slick underfoot.
Gear and Experience
- Essential Kit: You’ll want proper rain protection — a dependable waterproof jacket and pants, something to keep your pack dry, trekking poles for balance, and extra socks to change into at the end of the day.
- The Reward: Fewer trekkers and intensely green landscapes.
Final Words: July is not the easiest month on Manaslu. However, if you are okay with rain and changing plans, it can feel peaceful in its own way.
August (Monsoon: Humid with Rain Showers)
August continues the monsoon pattern; however, it often feels calmer than July. The rain is part of the experience, just not always as intense or constant, especially toward the end of the month.
The Weather
- Daytime: The temperatures range between 14°C and 23°C. It stays warm and humid, particularly in the lower valleys.
- Nighttime: They hover around 4°C to 9°C, which feels comfortable compared to the colder seasons.
Rain still falls regularly, but showers can be shorter, and you may get more breaks of clearer sky as the month moves on.
The Terrain
By August, the lower trail is damp in places. The forest sections can feel soft underfoot, and after a night of rain, mud becomes a part of the experience. Everything grows fast this time of year — bushes cover the path, and the air smells fresh and earthy.
- Larkya La Pass: It is usually still doable, but the mountains don’t always show themselves. Sometimes you are walking in white mist rather than expansive vistas as clouds drift in and out.
- Trail Surface: The ground is a bit more stable than in July. Even so, you still need to take your time on the slippery corners and steep sections.
Gear and Experience
- Essential Kit: A proper rain jacket, boots with a solid grip, trekking poles for balance, clothes that dry quickly, and something for insects in the lower forests help you deal with August Manaslu trek weather.
- The Reward: Fewer people, rolling clouds, and hills that look almost unreal in their deep green.
Final Words: August is not a perfect time for trekking in the Manaslu region. That said, it has its charm if you don’t mind a little rain.
September (Autumn: Clear and Pleasant)
After the monsoon, September feels like a refreshing reset for pleasant weather. That is because the heavy clouds begin to clear, the air dries out, and gradually the mountains come back into full view. As a result, the trails feel refreshed, washed clean from weeks of rain.
The Weather
- Daytime: 14°C to 22°C. Fresh, clear air returns as the monsoon fades.
- Nighttime: 3°C to 8°C. It feels cool after sunset, so you’ll want an extra layer once the temperature drops.
The Terrain
By early September, most of the mud from the monsoon starts to firm up. In addition, lower sections dry quickly once the rain fades, and walking becomes much more comfortable.
- Larkya La Pass: It is generally in good condition this month. Therefore, snow is rare, and visibility improves dramatically compared to July and August. You are far more likely to see the surrounding peaks clearly.
- Trail Surfaces: The trail generally feels stable underfoot, although a few damp patches can remain earlier in the month.
Gear and Experience
- Essential Kit: Regular trekking layers, a light jacket for cooler evenings, sun protection, and a warm sleeping bag for higher elevations.
- The Reward: Crisp air, sharp mountain views, and trails that feel alive but not overcrowded.
Final Words: September is when Manaslu trek weather truly opens up again — clear, steady, and incredibly satisfying to walk.
October (Autumn: Comfortable and Scenic)
October is one of the best times of the year for Manaslu trekking. This is because the rain is gone, the air feels clean, and most days start with clear skies. In fact, many trekkers specifically search for the Manaslu trek in October temperatures, as this month offers the most reliable conditions.
The Weather
- Daytime: 10°C to 16°C. The weather is ideal for trekking under clear skies.
- Nighttime: -2°C to -6°C. The temperature drops significantly at altitude, particularly before sunrise.
The Terrain
You can look forward to trek-friendly terrain in October.
- Larkya La Pass: The pass is usually in excellent shape. Fresh snow is uncommon, and views from the top can stretch far in every direction. Mornings can be cold, but once the sun hits, it warms up quickly.
- Trail surface: By this stage, the trail is generally dry and steady underfoot. Therefore, mud and slush aren’t much of a concern, and river crossings tend to feel calmer than they do during the monsoon.
Gear and Experience
- Essential Kit: A light down jacket for cooler moments, basic layers you can adjust during the day, gloves for early starts, and solid sun protection should be enough.
- The Reward: Clear mountain views almost daily and trails that feel lively but not chaotic.
Final Words: October just feels right in terms of Manaslu trek weather — steady weather, strong views, and walking conditions that make the effort worthwhile.
November (Autumn: Cool and Dry)
November feels quieter on the Manaslu trail. The rush of October starts to thin out, the air turns sharper, and mornings carry a noticeable cold vibe. Nonetheless, it is still a good month to trek — just a little colder and calmer.
The Weather
- Daytime: 6°C to 12°C. Cool and dry, with crisp mountain air.
- Nighttime: -5°C to -10°C. Freezing nights become common again above 3,500 meters.
The Terrain
In this last month of autumn, the weather is still ideal for trekking.
- Larkya La Pass: It is generally still open, although temperatures are lower, and occasional early snowfall can happen toward the end of the month. Most crossings remain manageable.
- Trail Surface: The trails remain mostly dry and stable, which makes walking straightforward. In the early mornings, you might notice frost on the ground, especially above 3,500 meters. However, it usually melts once the sun rises.
Gear and Experience
- Essential Kit: You’ll need proper warm layers — especially for evenings and early mornings — along with gloves and a sleeping bag that can handle freezing temperatures.
- The Reward: Quieter trails and clear, sharp mountain views.
Final Words: November is colder, but if you don’t mind brisk mornings, it’s a peaceful and rewarding time to trek.
December (Winter: Cold with Light Snow)
December brings winter back to Manaslu. The crowds thin out quickly, the air turns sharp, and you can feel the season shifting with every step higher up the trail.
The Weather
- Daytime: 0°C to 6°C. Cold days, especially in shaded or windy sections.
- Nighttime: -10°C to -18°C. Winter sets in fully, and serious cold returns at higher elevations.
The Terrain
Lower sections usually remain manageable, though mornings can start frozen. As you gain altitude, snow begins to settle along the path, especially in shaded areas.
- Larkya La Pass: It can usually still be crossed in early December, but once fresh snow falls, things can change quickly. Some days the path is clear enough; other days it can feel harder and slower going.
- Trail Surfaces: Early mornings often mean frozen ground under your boots. As the sun rises, the surface softens a little, but icy patches can stick around in shaded sections.
Gear and Experience
- Essential Kit: Warm base layers, a solid insulated jacket, proper winter gloves, insulated boots, and a sleeping bag that can handle serious cold.
- The Reward: The trail feels almost empty, villages are quieter, and the peaks look different under a layer of fresh snow.
Final Words: December isn’t the easiest time to trek Manaslu. Nevertheless, if you are prepared for the cold, then it can feel raw and quiet, as well as unforgettable.
Larkya La Pass Weather and Conditions
Larkya La Pass (5,106 m) is the most unpredictable factor on the Manaslu Circuit. In fact, many trekkers consider it a defining challenge of the entire route.
- Winter: Heavy snow and possible closure. As a result, crossings can become risky or completely inaccessible.
- Spring: Snow patches early in the season. However, conditions gradually stabilize as the temperature rises.
- Monsoon: Cloud cover limits visibility. Therefore, mountain views are often unclear despite manageable trail conditions.
- Autumn: Clear skies and stable crossings. Consequently, this season offers the safest and most scenic pass experience.
The temperature at Larkya La Pass can feel significantly colder due to strong wind exposure. Additionally, wind chill can make temperatures feel 5 to 10°C colder than actual readings. For this reason, early morning crossings are recommended for stability and safety.
Planning Your Manaslu Trek
Choosing the right season directly impacts safety, comfort, and visibility. Therefore, if you are considering a full Manaslu Circuit experience or a shorter 12 days budget Manaslu trek option, reviewing seasonal conditions first ensures better preparation and expectations.
However, do not forget that the region requires special permits, which are explained in our Manaslu restricted area permit information page. In addition, before starting your journey, always check the latest updates from the Department of Hydrology and Meteorology, Nepal’s official weather authority, to stay informed about the current weather conditions for the Manaslu trek.
