Nepal stretches from steamy Terai jungle to 8,000m peaks; timing shapes everything from Lukla flights to jungle visibility.
Spring (March–May)
Warming days, blooming rhododendrons, and strong trekking conditions in Khumbu and Annapurna. Afternoon clouds can build; start early for views.
Monsoon (June–August)
Heavy rain makes remote trails slippery and leeches common, but the hills are lush and crowds thin. Rain-shadow areas like Upper Mustang see far less precipitation.
Autumn (September–November)
Stable post-monsoon skies, crisp air, and major festivals: Dashain and Tihar bring family gatherings and street celebrations. Book teahouses and flights early.
Winter (December–February)
High passes may close with snow; Kathmandu, Pokhara, Chitwan, and low-altitude culture tours stay pleasant. High camps require warmer sleeping systems.
