Quick take: Timing your Nepal trip right makes everything better: lower prices, better weather, fewer crowds. Month-by-month reality below. October and November are the absolute best — clearest mountain views in the world, dry trails, comfortable daytime temperatures. March-April brings rhododendron season (one of trekking great spectacles) but with afternoon haze.
Nepal climate is dominated by the Himalayan monsoon — get the timing wrong and you cannot see the mountains for clouds; get it right and the Annapurna and Everest views are among the world greatest. Hiking seasons are extremely seasonal. Here is the proper breakdown.
Best time to visit Nepal: at a glance
Short answer: October–November for clear skies and trekking; March–April for rhododendrons.
| Season | Months | What to expect |
|---|---|---|
| Peak | Oct–Nov | Clear mountain views, prime trekking; busiest |
| Shoulder (best value) | Mar–Apr | Warm, blooms, good trekking |
| Low | Jun–Sep (monsoon), Dec–Feb (cold) | Rain & leeches, or cold with closed high passes |

Month-by-month overview
When to avoid Nepal
June through mid-September is monsoon — mountains hidden behind clouds, leeches on trails, landslides closing roads. Higher trekking routes (Annapurna Circuit Thorong La) are closed.
Key events and festivals
- Dashain (September / October (15 days)): Nepal biggest Hindu festival; entire country travels home, much closed. Visit before or after for trekking.
- Tihar (Festival of Lights) (Late October / early November): Five days of lights, family gatherings; lovely time to be in Kathmandu or Pokhara.
- Holi (Late February or March): Festival of Colors; powder paint celebrations citywide.
- Buddha Jayanti (April or May): Buddha birthday celebrated in Lumbini and at major monasteries.
A local insider tip
If you want the Himalayan view of a lifetime without trekking, fly to Lukla and back on a clear October morning, then go up to Nagarkot at sunrise (just 32km from Kathmandu) for the Langtang range view. You can do both in 48 hours and see what most trekkers spend two weeks earning.
The Shoulder-Season Sweet Spot Most Visitors Miss
October gets the headlines, but it hides a trap. Dashain, Nepal’s biggest festival, runs October 11 to 25 in 2026, with the main Bijaya Dashami day on October 21. Close to a million people leave the Kathmandu valley for their home villages during it, so domestic flights to Lukla or Pokhara and long-distance buses sell out fast. If you travel then, lock in internal flights two to three months ahead and pad your itinerary with buffer days for cancellations.
The smarter window for the same crystal-clear post-monsoon skies is mid-to-late November into the first two weeks of December. Trails that carried hundreds of trekkers a day in October thin out to dozens, teahouses have beds to spare, and rates on lodges and guides ease off the peak. Kathmandu sits cool and sunny at around 15 to 20C through December, ideal for valley sightseeing.
Two timing rules keep this window safe:
- Clear high passes such as Thorong La (5,416m) and Larkya La (5,160m) before late December, when snow usually closes them through February.
- Skip the last week of September, when the monsoon tail can still smother the mountains in cloud.
Frequently asked questions
When is the best time to trek to Everest Base Camp?
October-November (best visibility) and March-April (warmer, rhododendrons). Avoid June-September (monsoon) and December-February (very cold, snow risk at high passes).
When is the cheapest time to visit Nepal?
June through early September (monsoon) — flights and hotels can be 40-50% cheaper. Trade-off is rain and hidden mountains.
What is the weather like in Kathmandu year-round?
Mild — Kathmandu Valley sits at 1400m. Highs range 19°C (January) to 30°C (May). Pollution worst November-February (winter inversion).
When is Annapurna Circuit best?
October-November for clearest skies; March-April for rhododendrons. The Thorong La pass (5416m) is dangerous outside these windows.
Is Nepal safe to visit in monsoon?
Cities yes, but trekking is risky — landslides, leeches, poor visibility. Pokhara and Chitwan (jungle) are still good in early-mid June; everywhere else is best avoided.
