Nestled in the eastern Himalayas, Bhutan ranges from lush southern plains near India’s border to snow-covered mountains along Tibet. Lower altitudes enjoy a warm, subtropical climate, while central valleys see a temperate climate with distinct seasons. The far north experiences harsh alpine conditions year-round. The country is known for clear mountain views in autumn and spring, monsoon rains in summer, and chilly but sunny winters in much of the central region.

Temperatures
- Spring (March to May): Temperatures in central valleys like Thimphu range from 5°C to 20°C (41°F to 68°F), with blooming rhododendrons and crisp mornings. Lower southern regions can reach 25°C (77°F).
Summer/Monsoon (June to August): Warm and humid in lower areas (20°C to 30°C / 68°F to 86°F), cooler in higher altitudes (12°C to 22°C / 54°F to 72°F). Heavy rainfall and mist are common, especially in the south and along trekking routes.
Autumn (September to November): One of the best times to visit. Clear skies, mild temperatures (10°C to 23°C / 50°F to 73°F in the valleys), and stunning mountain views.
Winter (December to February): Central valleys see cool, dry weather with highs around 9°C to 15°C (48°F to 59°F) and lows near freezing. The far north remains frigid and snowbound, while the south stays mild and frost-free.
Rainfall
Bhutan receives the bulk of its rainfall from the southwest monsoon (June to August). Southern areas can see over 5,000 mm (197 inches) annually, while the higher valleys receive less—often between 500 mm and 1,500 mm (20–59 inches). Winter months are generally dry and sunny in the central valleys.
Snowfall
Snow is common in the high passes and northern mountains from late autumn through early spring. Central valleys like Thimphu may see occasional snow in January or February, while the south remains snow-free year-round. For trekking in alpine regions, April–May and late September–November offer the best conditions.
