Nepal’s climate varies significantly based on altitude and season, particularly in the Himalayan trekking regions. While days are generally clear at elevations above 2,500 meters, weather patterns can change unexpectedly.
The peak trekking seasons in Nepal are spring (March–May) and autumn (September–November).
Spring is one of the best times for trekking in Nepal. Wildflowers, including rhododendrons, bloom at elevations between 2,000–3,000 meters, creating stunning landscapes.
Daytime temperatures: 15–20°C
Morning & night: Can drop to -5°C or lower

Daytime temperatures: 15–20°C (sunny & pleasant)
