If you are planning a trek in Nepal in 2026, the short and honest answer is this: October and
November are the most stable and comfortable months for most trekkers. March and April come very close. That said, the “best” month depends on where you want to go, how much cold or rain you can handle, and whether you prefer quiet trails or lively teahouses.
Nepal has four clear seasons. Each one changes the mountains in a very real way. The skies, temperature, trail conditions, flight reliability, and even the mood of the villages shift from month to month. In this guide, we will break down every season & explain what actually happens on the trails, and help you match the right month with the right trek.
Understanding Nepal’s Trekking Seasons
Nepal sits between India and Tibet, and the Himalayas control its weather. You do not just get “summer” or “winter.” You get very different trekking conditions depending on the month.
Nepal has four main seasons:
Spring - March to May
Summer or Monsoon - June to September
Autumn - October to November
Winter - December to February
Each season affects famous trekking routes like the Everest Base Camp, Annapurna Circuit, Manaslu Circuit, and Langtang Valley in different ways.
Let’s go step by step.
Autumn Season - October and November
Why October Is the Most Recommended Month for Trekking in Nepal
If someone has only one chance in life to trek in Nepal, we usually suggest October.
Here is why:
The monsoon rain has just ended.
The air becomes clean and dust-free.
The mountain views are very sharp.
The temperature is comfortable at most altitudes.
Flights to Lukla and other mountain airports operate more regularly.
During October, daytime temperatures at 2,000 to 3,000 meters range from 10°C to 20°C. At higher elevations like Everest Base Camp, nights drop below freezing, but the skies stay clear.
You wake up, step outside the teahouse, and you actually see the mountains without clouds hiding them. That is not a small thing. In other months, clouds often block the view by afternoon.
October is peak trekking season. Trails are busy, especially in the Everest and Annapurna regions. Teahouses fill up quickly. You should book in advance.
November - Almost Perfect but Colder
November is very similar to October, but temperatures start to drop.
Advantages:
Clear skies continue.
Fewer trekkers compared to October.
Stable weather patterns.
Disadvantages:
Colder mornings and nights.
Higher passes can receive early snowfall toward late November.
If you are trekking to the Annapurna Circuit or crossing Larkya La on the Manaslu Circuit, late November can bring snow on the pass. It is manageable but requires proper gear.
For most people worldwide, October is slightly better than November. But if you prefer fewer crowds, early November works very well.
Spring Season - March and April
Many trekkers consider spring the second most popular time to trek in Nepal.
March - Clear Skies with Mild Cold
March marks the end of winter. Snow remains at high elevations, but lower trails start warming up.
Why March works well:
Stable weather.
Clear mountain views in the morning.
Moderate trekking traffic.
In March, daytime temperatures in popular regions stay comfortable. Higher areas still feel cold at night. If you plan Everest Base Camp, expect snow patches near Gorak Shep.
One thing to know - in spring, clouds often build up in the afternoon. You may get clear mornings and cloudy evenings.
April - Rhododendron Season
April is famous for blooming rhododendron forests, especially in the Annapurna and Langtang regions.
The national flower of Nepal covers hills in red, pink, and white. Forest trails look alive. If you are trekking through Ghorepani or Langtang Valley, April is visually beautiful.
Weather facts:
Warm daytime temperatures.
Higher chance of afternoon clouds compared to autumn.
Occasional light rain at lower altitudes.
If you care about photography and colorful landscapes, April may feel better than October.
Monsoon Season - June to September
Most people avoid trekking in Nepal during the monsoon. But it is not impossible.
What Actually Happens During Monsoon
Nepal receives heavy rainfall from June to early September due to the South Asian monsoon system. Rain mainly affects central and eastern Nepal.
Problems during monsoon:
Slippery trails.
Leeches in forest areas.
Landslides on highways.
Cloud-covered mountain views.
Flight delays.
In the Everest and Annapurna regions, visibility is often poor. Mountains remain hidden behind thick clouds.
However, rain-shadow areas like Upper Mustang and Upper Dolpo receive very little rain. These regions lie north of the main Himalayan range. If you trek in Upper Mustang in July or August, you get dry trails and fewer crowds.
If you are flexible and can handle rain, the monsoon offers:
Quiet trails.
Lush green landscapes.
Lower accommodation competition.
For beginners, we do not recommend monsoon for major high-altitude treks.
Winter Season - December to February
Winter trekking in Nepal is possible, but not for everyone.
December - Cold but Manageable
Early December still offers clear skies. It feels similar to late November but colder.
Advantages:
Very few trekkers.
Clear mountain views.
Lower prices in some areas.
Disadvantages:
Freezing nights.
Water pipes freeze in teahouses at high elevations.
January and February - Harsh at High Altitude
These are the coldest months.
At Everest Base Camp and Thorong La on the Annapurna Circuit, temperatures can drop below -15°C at night.
High passes may close due to heavy snowfall. If a pass gets blocked, you must reroute or turn back.
Lower elevation treks like Ghorepani Poon Hill or lower Langtang remain possible in winter. But you must prepare for the cold.
Winter suits experienced trekkers who understand altitude and cold management.
Month-by-Month Quick Breakdown for 2026
Here is a simple overview:
January - Very cold, good for low-altitude treks only.
February - Slightly warmer than January, still cold at high altitude.
March - Start of the good trekking season.
April - Warm and colorful landscapes.
May - Warmer and hazier skies.
June - Monsoon begins, heavy rain in most regions.
July - Peak monsoon except rain-shadow areas.
August - Similar to July.
September - Rain decreases late in the month.
October - Best overall month.
November - Excellent but colder.
December - Cold but clear.
Best Month Based on Popular Trek Routes
1. Everest Base Camp
Best months:
October
November
March
April
Avoid:
July and August due to cloud cover and flight delays.
2. Annapurna Circuit
Best months:
October
Early November
March
April
Avoid:
Peak winter, if you plan to cross Thorong La.
3. Manaslu Circuit
Best months:
October
Early November
March
April
This region is remote. During the monsoon, landslides can block access roads.
4. Langtang Valley
Best months:
October
November
March
April
Langtang works slightly better than Everest during early winter because it is lower in elevation.
Temperature and Altitude - What You Must Understand
Temperature drops as you gain altitude. For every 1,000 meters, the temperature drops roughly 6°C.
If it feels 20°C in Kathmandu at 1,400 meters, it may feel near freezing at 4,000 meters.
This is why month selection matters more for high passes like:
Thorong La on Annapurna Circuit
Larkya La on Manaslu Circuit
Cho La near Everest
Snow and wind at these passes can change conditions quickly.
Crowds vs Comfort - What Do You Prefer?
If you want:
Clear views and stable weather - choose October.
Fewer people and quiet trails - choose early December or late February.
Flower-filled forests - choose April.
Very low traffic and remote experience - choose Upper Mustang during the monsoon.
Be honest with yourself. Some people enjoy meeting trekkers from around the world. Others want silence.

Cost Differences by Month
Peak months like October and April often have:
