Manaslu Circuit Trek Weather & Best Time To Go

While planning the Manaslu Circuit trek, every trekker has one simple question in mind: “When is the weather good enough that this feels like an adventure, not a gamble? Or is it really just a one-season trek?”

Well, the quick answer to this long-lasting dilemma is: Manaslu is not a one-season trek. You can walk in it almost any month of the year. However, one needs to realize that temperature, snow level, trail conditions, and risk level change every season. It transitions a lot between the hot, humid river valley at around 800 to 900 m and the icy wind at Larkya La (5,160 m).

After studying Manaslu-specific climate data, its long-term weather patterns, and recent storm trends for 2026, we have developed this article with the hope that it will help you in deciding which season or which month will suit you best to trek in the Manaslu region in 2026.

Quick Answer on Best Time for Manaslu Circuit (2026)

Now, we absolutely understand not everyone wants to read the whole article based on the weather. So, here’s the short version capturing the essence of Manaslu Circuit’s weather and best time:

• The best season for the Manaslu Circuit trek is Spring and Autumn.
• In Spring, mid-March to mid-May, will suit most trekkers; meanwhile, in Autumn, mid-September to early November works best.
• During Spring, the daytime temperature ranges from 4 to 18 degrees Celsius, and at night, it can drop to -6 to -8 degrees Celsius.
• Meanwhile, in Autumn, the climate during morning and afternoon is roughly around 5 to 15 degrees Celsius, while at night it will hover between -6 and 5 degrees Celsius. 
• During spring and autumn, you can expect the best mix of stable weather, manageable cold, mostly dry trails, and clear views of the Himalayas.

Who Spring and Autumn windows are best for:

• First-time Himalayan trekkers
• People with limited time and no desire to “fight the elements.”
• Families and groups who want good odds of crossing Larkya La safely

How Manaslu’s Weather Actually Works (Route, Altitude & Zones)

Before looking at the specific months, we should first understand that the weather on the Manaslu Circuit trek varies because the trail itself rises and falls through a variety of landscapes.

Most of the time, treks follow a clockwise route that starts from the warm lowland. Then, you gradually climb into the high alpine terrain.

Summary of What the Manaslu Circuit Route Looks Like

You begin from Kathmandu and drive to Soti Khola or Machha Khola at around 800 to 900 m, then trek through villages such as Jagat, Deng, and Namrung between 2,000 and 2,700 m.

From there, the trail climbs into the high Buddhist villages of Lho, Samagaon (around 3,500 m), and Samdo (about 3,850 m), before reaching Dharamsala/Larkya Phedi at roughly 4,460 m. The highest point is Larkya La Pass at 5,160 m, after which you descend to Bimthang and exit the trail by road from Dharapani.

Weatherwise, you climb from humid river gorges into cold, windy, high-altitude terrain, and then you descend back. In fact, this steady change in weather is one of the main reasons why Manaslu’s weather feels so varied within a single trek.

Climate Zones You Cross During the Manaslu Circuit Trek

One thing people often fail to realize is that above 3,000 m, the valley’s temperatures drop faster, and winds become stronger. In fact, if you are trekking in winter, the snow can remain for much longer, so you need to attach crampons or ice cleats to your trekking shoes.

The table below shows how these climate zones change with altitude and which villages or sections of the trail fall within each band.

In practical terms, this means temperatures drop by 0.6 to 0.7 degrees Celsius for every 100m that you gain. For example, a mild 15 degrees Celsius in the Jagat or Philim can feel near freezing at Samagaon (3,530 m). This rapid change with altitude is why seasonal timing matters so much on the Manaslu Circuit.

Manaslu Circuit Weather by Season

We guess you now have a pretty good idea of how the trail climbs. But you haven’t yet experienced how the temperature will be like in each season of Nepal:

Before diving into each month, here’s a quick temperature reference at mid-altitude (3,500 m):

Month-by-Month Weather Guide for 2026

Now let’s turn this into something you can actually plan with. Instead of long stories for each month, here is a plain-language planner you can scan and decide: “Yes, this feels like me” or “No, not worth the stress.”

January–February

This is the coldest and quietest time on the Manaslu Circuit. The lower trail stays cool but manageable, while the real challenge begins above 3,000 m where snow and ice dominate the landscape.

Larkya La can be blocked or unsafe for days; some lodges close, and you will see very few trekkers on the trail. This window is only for very experienced winter trekkers with a guide, strong gear, and extra buffer days built into the plan.

March–May

Spring is when Manaslu starts to wake up. March still carries some winter cold, with daytime temperatures around 4–12°C at mid-altitude and nights dropping to -6 to -10°C. By April, things warm up to 6–16°C during the day and -2 to -8°C at night. Come May, you can expect 8–18°C in the daytime and -2 to -5°C once the sun goes down.

The trails are mostly dry, though you will still find snow and ice near Larkya La, especially in March. Mornings offer clear views, but late May can bring a few clouds or pre-monsoon storms. The lodges get busy in April and early May, so expect to share the trail with other trekkers.

Good for:

• First-time Himalayan trekkers
• Families or groups who want stable weather
• Anyone who wants blooming forests and clear mountain views

June–August

Monsoon is green, wet, and dramatic. At mid-altitude, daytime temperatures sit comfortably between 14–23°C, and nights cool down to 4–9°C. The problem is not the temperature but the rain.

Trail challenges you will face:

• Muddy and slippery paths throughout
• Leeches in the lower forests
• Landslides and rockfall in narrow valley sections
• Rivers and side streams rise quickly after storms
• Mountain views are often blocked by clouds

Very few trekkers choose this season. If you are a first-time trekker or someone who gets stressed by delays and plan changes, the monsoon is not your season. This works only for very experienced trekkers who accept mud, rain, and the reality that, on some days, you simply cannot move forward.

September–November

Autumn is when Manaslu shows its best face. Early September still carries some leftover monsoon mood with temperatures around 12–18°C during the day and 3–8°C at night. By October, things settle into 10–16°C in the daytime and -2 to 5°C at night. November gets colder, with days around 5–13°C and nights dropping to -6°C or lower.

This season is perfect for first-timers, photographers, and anyone doing a “once in a lifetime” Manaslu trip where crossing the pass safely matters more than having the trail to yourself.

December: Early Winter, Quiet Again

December is a slow slide into winter. At mid-altitude, daytime temperatures sit around 2–12°C, and nights drop to -8 to -2°C or lower. Up at the pass, it is well below freezing all day and night. Increasing ice and snow appear at higher sections, and Larkya La may be blocked after big snowfalls. Some lodges start closing as traffic drops.

This month suits experienced trekkers who want quiet trails and are ready for real winter conditions. You need flexible dates because in some years, you simply cannot cross the pass.

Should You Trek in Monsoon or Winter?

Some people ask, “If it’s possible to trek all year, why not just go whenever my holiday allows?” The honest answer is: yes, it’s possible, but in monsoon and winter, the line between “adventure” and “unnecessary risk” becomes very thin.

Think twice about monsoon if:

• You are a first-time trekker in Nepal
• You hate walking in heavy rain and mud
• You get stressed by delays, road closures, or changed plans

Think twice about deep winter if:

• You don’t have proper cold-weather gear
• You are not used to snow, ice, and -15°C nights
• You cannot add buffer days in case Larkya La is not safe to cross

If you still decide to go in these seasons, make sure you have a flexible return ticket, extra buffer days, and a licensed guide who knows how the trail behaves in heavy snow or rain.

Climate Change & Why Seasons Feel Less Predictable

In recent years, weather in the Nepal Himalaya has started to feel a bit less “fixed.” You may see monsoon rain stretching into September or even early October. Late snowfalls can hit in spring, or sudden heavy snow can arrive in late October or November. Short but intense storms now bring a lot of rain or snow in just a few hours.

What this means for you is simple: even in “good months” like April and October, keep 1–2 buffer days in your plan. Be mentally ready to wait a day in Samagaon or Larkya Phedi if local guides say the pass is not safe. Checking the forecast helps, but in Manaslu, local advice is still your best weather tool.

Simple Decision Guide: Which Month Is Best for You?

Instead of asking “Which month is best?” ask “Which month is best for my style?”

Pick March or November if you:

• Like quieter trails
• Are okay with colder nights and some ice
• Travel with good gear and a guide

Pick April or October if you:

• Want the safest balance of weather, views, and comfort
• Are a first-time high-altitude trekker
• Are traveling with family or a mixed-ability group

Pick late September or late May if you:

• Like a “shoulder season” feel
• Can accept a bit more weather risk for fewer crowds

Avoid June–August and mid-winter unless you:

• Already know how to trek in heavy rain or snow
• Have flexible time and strong mental tolerance for plan changes

Safety & Buffer Days: Turning “What If” Into a Plan

Even in the best season, weather can still slow you down. A smart plan accepts this from the start instead of fighting it.

Simple rules:

• Add 1–2 extra days into your Manaslu itinerary in spring and autumn
• Add 2–3+ extra days if you travel in monsoon or winter
• Do not lock your international flight on the same day you expect to exit the trek
• If locals in Samagaon, Samdo, or Larkya Phedi say “not safe today,” treat that as hard weather data

From a safety and comfort point of view, these buffer days are not wasted time. They are the thing that often turns a stressful trip into a calm one.
