Nepal · Month comparison
May vs October
October ranks #1 overall vs May at #5. The finest month — crystal-clear skies, Dashain festival, and the most dramatic mountain views of the year.
May
#5 of 12 months
Best match
Pre-monsoon window — Everest summit week, increasing clouds, but still excellent for lower circuits.
- ↑May is Everest summit month: the weather window typically opens between May 10–25, and the concentration of summit attempts in this period creates the most dramatic high-altitude activity visible from EBC and Kala Patthar; watching 40–50 headlamps moving up the SE Ridge through binoculars from the EBC moraine at 3am is one of the most extraordinary viewing experiences in Nepal
- ↑Lower altitude trekking circuits (Poon Hill, Annapurna Sanctuary, Langtang Valley) remain excellent in May: the pre-monsoon warm temperatures, the tail of the rhododendron season, and the increasing lushness as moisture builds create beautiful hiking conditions at elevations below 3,000m
October
#1 of 12 months
Best match
The finest month — crystal-clear skies, Dashain festival, and the most dramatic mountain views of the year.
- ↑October delivers Nepal's most celebrated conditions: the monsoon has ended, the air has been washed clean, and the Himalayan panoramas — Everest from Kala Patthar, Annapurna from Poon Hill, Ganesh Himal from Nagarkot — are at their sharpest and most dramatic; photographers and trekkers specifically plan years around October visits
- ↑Dashain (Nepal's most important Hindu festival, date varies late September–October) transforms the country: a 10–15 day celebration featuring kite-flying, family reunions, animal sacrifices at Durbar Squares, and the blessing of children by elders with tika (coloured powder and yoghurt); the atmosphere in Kathmandu during Dashain is the most culturally charged of any month

May trade-offs
- ↓Monsoon-driven cloud build-up accelerates through May: mountain viewpoints above 4,000m become progressively obscured after 9–10am as afternoon cloud builds; the critical Kala Patthar view of Everest summit requires a 4am start for clear visibility, and some May weeks see the mountain invisible from Base Camp for days at a time
- ↓130mm of rain and 72% humidity represent a significant shift from April — the lower valleys and Kathmandu city are warm and humid, and afternoon showers become a daily reality; high-altitude circuits above 5,000m are still dry but the approach valleys become muddier
- ↓The Khumbu Icefall becomes increasingly unstable in May as temperatures rise: summit teams accelerate their activity to complete rotations before the icefall deteriorates; this creates a deadline-driven, high-energy atmosphere at EBC that is fascinating to observe but signals the approaching monsoon closure
October trade-offs
- ↓October is the most competitive accommodation month in Nepal: the EBC route lodges in Namche Bazaar, Tengboche, and Gorak Shep book out weeks to months in advance; the Annapurna Circuit tea houses similarly fill rapidly; arriving without confirmed accommodation for the high-altitude stages of any circuit in October is inadvisable
- ↓October peak season pricing: tea house rates double or triple from monsoon prices, guides and porters charge premium rates, and permit prices for restricted areas are unchanged but the total trip cost is highest of any month
- ↓Dashain creates specific practical challenges: many Kathmandu shops, restaurants, and services close for 10 days around the festival; bank hours change, tourist taxis become harder to find as drivers return to their home villages, and logistics around the festival period require advance planning
