Nepal's vast differences in area make the country a top-rated trekking and touring destination. The best seasons in Nepal for trekking are in spring and fall when climbers have beautiful mountain views and there is less chance of getting stuck on trails due to rain or snow.
Why Timing Matters?
The weather varies tremendously by area, with certain areas having a much different climate than others. For example, the city of Kathmandu has mild temperatures throughout the year. Trekking on high-altitude trails requires significant amounts of advance planning to ensure access to supplies, and to understand when it is best to share trails with many other trekkers.
In addition to planning the time to go to Nepal, it is essential to plan to take enough food and equipment for the journey. Therefore, when planning a trip to Nepal, it is essential to ensure that the visit is as successful as possible.
Autumn Season (September-November)
Trekking is best done in the autumn due to the clarity following the monsoon season and the views of Everest and Annapurna when they're completely clear. The temperatures during the daytime at lower elevations are generally 15° to 20°C and at elevations above 3,000 m during the nighttime you can expect to experience temperatures near freezing, allowing for longer durations of trekking in the best conditions. The Langtang Valley trekking route and the Manaslu Circuit trekking route are extremely busy during the early part of the autumn, with the crowds thinning towards the end of the autumn.
- September: September starts with light rainfall; however, by the middle of September, most of the rain should have stopped and the views will be amazing due to the lush greenery caused by the rain.
- October: October is when the trekking conditions are at their best. The weather is generally very stable, there are also numerous festivals that take place throughout the month, allowing for a wonderful cultural experience while trekking. Flights to Lukla are operating regularly throughout the month.
- November: November begins to be cooler, with daytime temperatures ranging from 10° to 15°C; however, the crowds are thinning during this time and the views from the trekking routes can be spectacular, especially when experiencing the beautiful sunset over the snow-covered peaks.
Chitwan National Park and Pokhara continue to be very active during this time of year. Because of the dry trails, it is an excellent time of year for both jeep safaris and paragliding. Autumn is the perfect season for multi-day treks and combining multi-day treks with a visit to Kathmandu.
Spring Season (March-May)
Spring is one of the best times of the year to trek. The days are warm (15° to 25°C at elevations below 3,000 m) and the hills are alive with flowers painting the Himalayas a pink hue. There are clear skies with very few clouds; however, some clouds do build up in the afternoons. Above 3,000 m the rhododendrons start to bloom creating a colourful carpet of flowers along routes such as the Ghorepani Poon Hill trekking route. The trails are much less crowded than they are in October, making it a photographer's paradise.
- March's warming trends after winter lead to longer days—perfect for acclimatization treks, such as Helambu.
- April offers an ideal balance between vibrant flora and moderate crowds; peak trekking traffic at Everest Base Camp before the craziness of October.
- May is the hottest month before the monsoon; the longer days help trekkers push to altitude, but the haze before the monsoon can be an issue.
For cultural tours, clear views of sacred sites such as Muktinath create an excellent experience; there are also lots of birdwatching opportunities for park visitors, and birdwatchers can enjoy the many opportunities available while trekking.
Monsoon Season (June-September)
Most trekkers will want to steer clear of the monsoon due to the constant storms that bring with them muddy, slippery trails and the risk of landslides. This time of year will see temperatures range between 20-30 C in the valleys, leading to lush tropical forests and cloudy tops of the mountains (Annapurna and Everest trek routes). On the positive side, there will be considerably fewer people trekking in the region. The price of trekking packages will also be considerably lower. Green terraced rice fields will also provide an added bonus to trekkers.
Jungle tours in Bardiya and Chitwan offer the best wildlife sighting opportunities during the monsoon months, as the rivers will swell, forcing animals to congregate near the water holes. Cultural tours in the Kathmandu valley can be undertaken, and the rain during the monsoon adds to the beauty of ancient temples. Serious adventurers may want to consider trekking in Upper Mustang and Dolpo as both regions are protected from the rain due to the rain shadow created by the Himalayas.
Winter Season (December-February)
During winter, you can expect warm sunny days on your trek as there is very little chance of snow below 4000m. Travellers should expect nighttime temperatures to drop below freezing. Winter's daytime temperatures in Pokhara are from 10-15C, while the Everest region has much colder conditions. During the winter months, Thorong La Pass often becomes impassable. Due to the lack of haze, the visibility in winter is excellent, and short treks such as Poon Hill or Tamang Heritage Trek offer the opportunity to enjoy exceptional views.
The views of snow-capped mountains create a picture-perfect setting for photographers. Most teahouses along the main trekking routes are equipped with wood stoves for warmth. The winter season is an affordable time to travel to Nepal, as flights are very reliable. Tours of Lumbini or Bhaktapur during the winter are ideal as the cooler temperatures make cultural walks much more pleasant. Yoga retreats and walks amidst the beautiful mountainous landscapes rejuvenate and energise you after your hikes.
Popular Trekking Seasons in Nepal
With over 5,000 trekking routes, seasonality enables optimal experience:
- Everest Base Camp: Best views in the fall, spring avoids more ice, the winter is possible, but requires crampons. Avg. time = 12-14 days
- Annapurna: Crosses Thorong La safely in the fall; spring is awesome because everything is blooming and the weather is better (moderate weather). Avg. time = 14-21 days.
- Langtang Valley: Accessible year-round; winter is best for immersing yourself in Tamang culture. Avg. time = 7-10 days.
- Upper Mustang: Best in monsoon because of its location in the rain shadow; gets you up close and personal with hidden Tibetan kingdoms. Avg. time = 10-14 days.
There are also shorter tours like the Nagarkot Sunrises and Chandragiri cable car rides, which are accessible year-round, and can be combined with treks for hybrid itineraries.
Regional Considerations
Nepal’s geographical features dictate regional considerations, such as:
- Everest/Khumbu: The fall is prime time; spring is the second best, and avoid the monsoon if you plan to fly.
- Annapurna: The best time to hike both of the peaks is in the winter.
- Dolpo/Upper Mustang: The best time to trek this area is during the monsoon season due to the dry rain shadow effect.
- Kanchenjunga: The best time to trek in the remote eastern part of Kanchenjunga is in the spring, while autumn is a distant second.
Kathmandu and Pokhara tours operate all year round, however, as the majority of them are indoors (museums, etc.), they are buffered from the seasonal changes in the weather — i.e. they can operate in the winter.
Trekkers to Nepal should consider items such as permits (TIMs), national park fees, and acclimatization when planning their treks. If you rush your trip, you may risk altitude sickness.
Packing for Trekking in Nepal
Clothing should be layered. Use a thermal (base), fleece, and waterproof jacket for any season. Trekking poles are useful for added stability, and high-quality trekking boots can prevent blisters. Hydration needs are higher (due to dry fall conditions).
Hire a guide for your trek, as Nepal does not have handrails on its trails.
- Use Sunscreen, UV-Proof Hat.
- Take Diamox for altitude acclimatization.
- Bring Cash for Tea House Stays (NPR 1000-3000/night).
- Have a Health Check Before Travel and get Travel Insurance for Evacuation Coverage.
- Practice Sustainable Travel - Carry out what you Bring In, Support Porters' Rights, etc.
Festivals Enhance Visits
Plan Treks around Festivals.
- Dashain/Tihar (October) - Focusing on Family Celebrations in fall and celebrations along the trails.
- Lhosar (February/March) - Tibetan New Year celebrated in higher valleys.
- Holi (March) - Winter festival; start of Spring season, and color festival in the lowlands.
All of these Festivals add a level of Authenticity to the trekking experience from the Buffalo Sacrifices during Dashain to Butter Lamps during Tihar.
Conclusion
