Nepal Trekking Seasons: Autumn vs Spring vs Winter vs Monsoon

Nepal's trekking seasons are dramatically different — choosing the right one for your trek type can make or break the experience.

Autumn (October–November): The Gold Standard

Weather: Post-monsoon clarity, crisp blue skies, minimal cloud.

Temperatures: 15–25°C in Kathmandu; -5 to 5°C at high camps.

Trails: Excellent — dry, well-maintained, busy but manageable.

Best for: All routes — EBC, Annapurna Circuit, Manaslu, Kanchenjunga, Three Passes, Island Peak, Mera Peak.

Spring (March–May): Second Best

Weather: Good, though afternoon clouds build above 4,000m from April.

Highlights: Rhododendron season — the lower valleys are spectacular in March–April.

Best for: All routes. EBC climbing expeditions happen during spring.

Monsoon (June–September): Rain Shadow Routes Only

Weather: Heavy rain on southern slopes. Northern rain-shadow regions (Mustang, Dolpo, Nar Phu) remain relatively dry.

Best for: Upper Mustang, Dolpo, Nar Phu. Avoid southern slope routes.

Advantages: Extreme solitude, lush green landscapes, 30–40% lower prices.

Winter (December–February): Low Altitude Only

Weather: Cold and clear. High passes typically closed by snow.

Best for: Poon Hill, Tamang Heritage Trail, Helambu below 3,500m, Chitwan, Lumbini.

Avoid: Thorong La, Larkya La, Renjo La, Cho La — typically snow-closed.

Practical Tips

Book inter-city transport in advance during autumn peak season — buses on the Kathmandu–Pokhara route fill up weeks ahead. Use Sajilo's bus booking at sajilo.net/bus for guaranteed seats.

FAQ

Which season is cheapest? Monsoon and winter — accommodation and guided tours can be 30–40% cheaper.

Is March or October better for EBC? October is preferred for clear mountain views. March has more spring atmosphere and rhododendrons.

Can I trek Mustang year-round? Almost — Mustang's rain shadow makes it trekable in monsoon, but winter is cold at Lo Manthang's 3,840m elevation.
