Spring (March to May): A Season of Renewal
Overview
Spring in the Himalayas is a time of renewal and awakening. After a long, harsh winter, the snow begins to melt, rivers swell with fresh glacial water, and valleys bloom with rhododendrons, orchids, and wildflowers.
Weather and Temperature
- Low altitudes (up to 1,500 m): 10°C to 25°C
- Mid altitudes (1,500 – 3,000 m): 5°C to 20°C
- High altitudes (above 3,000 m): -5°C to 10°C
Skies are mostly clear, and temperatures are moderate, though chilly nights persist at higher elevations. Occasional showers may begin in late May as pre-monsoon patterns emerge.
Travel Highlights
- Ideal trekking conditions in regions like Uttarakhand (Kedarnath, Chopta), Nepal (Annapurna, Langtang), and Sikkim.
- Excellent wildlife spotting in parks like Jim Corbett, Valley of Flowers, and Singalila.
- The famous rhododendron blooms in Nepal and North Sikkim peak around April.
Travel Tips

- Mid altitudes: 15°C to 25°C
- High altitudes: 5°C to 20°C

Autumn (September to November): Clarity and Color
Overview
Autumn is widely considered the best season for Himalayan travel. With the monsoon rains gone, the skies are crystal clear, offering some of the most breathtaking views of snow-clad peaks.
Weather and Temperature
- Low altitudes: 10°C to 25°C
- Mid altitudes: 5°C to 20°C
- High altitudes: -5°C to 15°C
Crisp air, moderate temperatures, and low humidity make this season ideal for trekking and sightseeing. Autumn also coincides with post-harvest festivals in the Himalayan belt, offering a glimpse into rich local cultures.

Winter (December to February): Snow, Silence, and Solitude
Overview
Winter transforms the Himalayas into a snow-covered wonderland. While many high passes and treks become inaccessible, the lower and mid-Himalayas offer a peaceful retreat with fewer tourists.
Weather and Temperature
- Low altitudes: 0°C to 15°C
- Mid altitudes: -5°C to 10°C
