Climate Overview

Nepal has dramatic climate variation across its three major geographical zones — the tropical Terai lowlands, mid-hill region containing Kathmandu and Pokhara, and high Himalayan peaks. Kathmandu Valley (1,400m) experiences a temperate climate with four distinct seasons, while the Terai is subtropical and the high mountains alpine. The monsoon (June-September) brings heavy rainfall to most of the country except the northern rain shadow zones of Mustang and Dolpo.

Seasonal Breakdown

Detailed information for each season.

🌸 Spring

Mar-May

Nepal's most beautiful season with rhododendrons blooming in pink and red across mountain slopes, mild temperatures in Kathmandu (15-25°C), and good trekking visibility. April is peak spring month with wildflowers and comfortable conditions.

Tips: Pack light layers for mornings and evenings; afternoons warm up quickly. Bring rain jacket for occasional pre-monsoon showers in late May.

☀️ Summer

Jun-Aug

Monsoon season with heavy rainfall transforming Nepal green but causing cloudy skies obscuring mountain views. Hot in Kathmandu (22-30°C) and extremely hot in Terai. Leeches on jungle trails, landslide risks on mountain roads.

Tips: Bring quality waterproof gear, leech socks for jungle trekking, and quick-dry clothing. Upper Mustang and Dolpo are exceptional in monsoon as they sit in rain shadow.

🍂 Fall

Sep-Nov

Nepal's premier season with crystal-clear post-monsoon skies, dramatic mountain views, comfortable temperatures (10-22°C), and the best visibility for Himalayan panoramas. October-November are peak months for EBC and Annapurna circuit treks.

Tips: Book accommodation and flights well in advance — October is Nepal's busiest month. Evenings cool quickly at altitude; pack warm layers.

❄️ Winter
