Nepal is the roof of the Earth, the country of lofty mountains, and soft, rolling valleys. Weather in Nepal can be rather moody, so as a visitor, it’s important for you to understand the varied climate of this beautiful country, so that you know when to visit. After all, you’ve got to visit when the country is at its beautiful best!
- High Season: March - May and September - November
- Low Season: June to August
- All Seasons: March to May, June - August, September - November, December - February
- The Fall months of September to November is one of the best time to visit Nepal, for people who wish to visit Kathmandu, and for those who want to trek.

You’d expect the home of the Himalayas to be chilly round the year, but it really does have a varied climate. October and November, or the fall season, is the best time to visit Nepal, as there will be sunny days, and clear skies, making these months ideal for those who want to trek. Between the months of March and May, tourists can enjoy the best of the spring season. There will still be some chill in the air, but the flowers will burst into bloom, and the sun will be up! This is also a great trekking season with clear skies, however, the skies may not be as clear as during October.
If you are primarily trekking in the mid-lands region, and want to know when to visit Nepal, know that there is pleasant weather the entire year round, perhaps with the exception of January / December, where it’s rather cold, but even that period is okay, if you have warm enough clothes. Monsoon season in Nepal is from mid-June to mid-September. It’ll rain a couple of hours a day and be mostly cloudy, but still with clear skies some days.
March to May – Spring / Good Season
March - May is the second best time to visit Nepal. These months are rather warm, and there is plenty of sunlight. Long days and great visibility make this period a great time for a trek. The nights might be slightly chilly, so remember to pack warm clothes. The valleys are incredibly beautiful in the spring season, especially after all the ice has thawed, and the flowers have bloomed. By the month of May, some showers also begin slowly, leading up to the upcoming monsoon season in Nepal, starting mid-June.
- Average Temperature: 16 – 71° F
- Rainfall: 10 – 70 mm
- Highlights: Spring is always a great season to visit Nepal and all treks can be undertaken during this period, even climbs to e.g. Island Peak, Mera Peak etc. Those looking for a more culturally oriented journey will find Bhaktapur to be a great place to visit in April. The traditional Nepali new year festival of Bisket Jatra Navavarsha is celebrated with great pomp and splendor in this quaint Nepali town and it is an experience you won’t observe anywhere else! Spring is also the best time to do a jungle safari in Chitwan National Park, giving you the best chances of spotting Rhinos, Elephants, Tigers, Monkeys etc. Especially tigers are easiest to find during Spring is there is only a few water holes available in the park, which most animals will visit, including the beautiful tigers.
June to mid September – Summer / Wet Season
The months of June to August are not ideal for visiting Nepal, but it’s still entirely possible to visit. It’s quite hot, and the lower regions can get rather dusty. From mid-June the monsoon season starts with 1-2 hours rain a day, also clearing away the dust. On the worst days it rains the entire day. The visibility in the mountains is rather low, however, still with occasionally clear days. Due to the daily rain there is a risk of landslides in the upper regions, so it is highly recommended that you avoid certain trekking areas. Please see further below.
- Average Temperature: 23 – 71° F
- Rainfall: 129 – 239 mm
- Highlights: There are some treks that are particularly good during monsoon season as they lie in the rain shadow. Those treks are: Annapurna Circuit, Manaslu trek, Upper Mustang trek, and the Nar Phu Valley Trek. The famous Everest Base Camp trek can also be done during the monsoon season, but please expect rain during the first few days after which the weather will improve day-by-day. An advantage of having the monsoon season is crowd-free experiences. You’ll also be able to get good rates at normally busy destinations such as Chitwan, Pokhara and Bandipur. Marsyangai Valley and Tilicho Lake (placed along the Annapurna Circuit) are absolutely beautiful this time of the year and are known for their lush greenery and great views.

December to February – Winter / Low Season

Such includes: Gokyo and Everest Base Camp, where the Cho La Pass my be closed, the Gokyo Circuit trek, where the Renjola Pass may be closed, and the EBC 3 Passes trek, where all 3 passes may be closed.

Recommended treks during the winter season are: Everest Base Camp Trek, Annapurna Circuit Trek, Langtang Trek, and the Poonhill Trek. During winter, normally daytime is okay, however, morning time and nighttime see a drastic drop in the temperatures. Thus, if you do go trekking in Nepal during this season, please bring sufficiently warm clothes. It is also not recommended to do any climbing in Nepal during this season as it’s simply too dangerous and too cold.

- Rainfall: 0 – 8 mm
- Highlights: If you are an adventurer who wishes to experience the harsh Himalayan winter, enjoy the above mentioned hiking trails without any crowds, and save quite a bit of money on accommodation and travel, this is a good period to visit Nepal.

The Tibetan New Year’s Celebration is celebrated in Losar in the month of January and is an experience of a lifetime.
