Best Time to Visit Nepal for Trekking & Sightseeing (2026)
Quick answer
For trekking, October–November is Nepal's clearest and most stable window, followed by March–May for milder weather and blooming rhododendrons. Avoid June–August (monsoon) for mountain routes — trails get muddy and mountain flights are frequently cancelled. December–February suits lower-altitude trekking and city sightseeing but closes some high passes. Kathmandu Valley itself is worth visiting almost any month.

Nepal's seasons at a glance
| Season | Months | Good for | Watch out for |
|---|---|---|---|
| Autumn (peak) | Oct–Nov | Everest Base Camp, Annapurna, clear mountain views | Busiest trails and teahouses — book ahead |
| Spring | Mar–May | Rhododendron blooms, milder temperatures | Haze can reduce distant mountain visibility |
| Monsoon | Jun–Aug | Upper Mustang & Dolpo (rain-shadow areas) | Leeches, landslides, cancelled mountain flights |
| Winter | Dec–Feb | Kathmandu, Pokhara, Chitwan, lower treks | High passes close; very cold above ~4,000m |
Best time for Everest Base Camp and the Khumbu region
Everest region trekking is most popular in October–November, when post-monsoon skies are typically clearest and the classic mountain panoramas are at their best. Spring (March–May) is the second window, favoured by climbers heading toward Everest Base Camp before the pre-monsoon expedition season. Both windows see Lukla's small mountain airport at its busiest, so book flights and teahouse stays as early as you can.
Best time for Annapurna and Pokhara
The Annapurna Circuit and Annapurna Base Camp trek follow a similar pattern to Everest: October–November for the clearest views, March–May for milder days and flowering rhododendron forests along lower elevations. Pokhara itself, as the trailhead town, is pleasant nearly year-round except during the heaviest monsoon weeks.
Why monsoon season is different in the rain shadow
Not all of Nepal follows the same monsoon pattern. Upper Mustang and Dolpo sit in the Himalayan rain shadow, so they stay comparatively dry even in June–August when the rest of the country is wet — a niche but genuine option for travellers set on a summer trip.
Winter trekking and city travel
December to February is cold at altitude but entirely workable for lower routes like Ghorepani Poon Hill, and it's a good season for Kathmandu Valley's temples, Pokhara's lakeside, and Chitwan National Park's wildlife safaris. High-altitude passes such as Thorong La on the Annapurna Circuit typically close to snow in deep winter, so check current route conditions before committing to a high-pass itinerary in this window.
Mountain flights need buffer days
Flights to Lukla, Jomsom and other mountain airstrips are notoriously weather-dependent and can be delayed or grounded for several days in a row, particularly outside the clearest autumn window. Build at least one, ideally two, buffer days into your schedule before an international departure so a delayed mountain flight doesn't cost you your flight home.
Getting to Nepal and tracking your flight
Tribhuvan International Airport (KTM) in Kathmandu is Nepal's only major international gateway, typically reached via connections through Delhi, Doha, Dubai or Bangkok. Compare routings on ScanFlyGo's flight search, and once booked, use the live flight tracker to watch both your international inbound flight and any domestic mountain connection for delays.
Frequently asked questions
What is the best month to trek in Nepal?
October and November are peak season with the clearest skies. March–May is the second-best window with milder weather.
Should I avoid Nepal during monsoon season?
For trekking, yes — June–August brings rain, leeches and landslide risk. Kathmandu Valley alone is manageable with flexible plans.
Is winter a good time to visit Nepal?
It works for lower-altitude trekking and city sightseeing, but high passes above roughly 4,000m can close due to snow.
Do mountain flights get delayed often?
Yes, especially to Lukla — build 1–2 buffer days into your itinerary around any mountain flight.
The bottom line
Time a trekking trip to Nepal for October–November if you can, with March–May as a strong second choice, and avoid high-altitude routes in monsoon season. Whatever the plan, build buffer days around mountain flights. Search live fares on ScanFlyGo and check popular routes into Kathmandu before booking.
