Bhutan Weather:
Month by Month Guide
Bhutan's weather is determined primarily by altitude — the country spans from subtropical lowlands to high Himalayan passes. This guide gives you exact temperatures by month and region so you can pack and plan with confidence.
Understanding Bhutan's Climate
Bhutan's climate cannot be summarised in a single sentence because altitude creates dramatically different conditions across the country. The southern foothills (200–1,500m) are subtropical and humid year-round. The central valleys where most tourists travel — Paro (2,280m), Thimphu (2,320m), Punakha (1,200m), Bumthang (2,800m) — have a temperate highland climate with four distinct seasons. The high alpine zones above 3,500m experience subarctic conditions with snow from October through April.
For practical planning purposes, the weather that matters most is in the central valleys. Punakha, sitting lower than Thimphu and Paro, is noticeably warmer — often 5–8°C above Thimphu on the same day. Bumthang, at the highest elevation of the main tourist circuit, is noticeably colder. Understanding these regional differences is key to packing correctly.

Weather by Region
Paro (2,280m)
Paro experiences the classic highland climate of western Bhutan — warm summers, cold winters, spring blossoms and autumn clarity. The valley is sheltered and generally drier than Thimphu. Winter snowfall is possible but rarely disrupts road access. The airport can close in winter fog, which occasionally affects flight schedules. Best months: March–May and September–November.
Thimphu (2,320m)
Very similar to Paro with slightly higher rainfall due to its position. The capital's elevation makes it noticeably cooler than Punakha. Evenings require a jacket year-round except in peak summer. Best months: March–May and September–November.
Punakha (1,200m)
Punakha is Bhutan's warmest destination on the main tourist circuit — sitting 1,100m lower than Thimphu, it can feel subtropical by comparison. The Punakha Valley floor is lush and green even in winter. The Punakha Dzong, built at the confluence of two rivers, experiences flooding risk during heavy monsoon — check conditions if visiting June–August. Best months: February–April and October–December.
Bumthang (2,800m)
The highest and coldest of the main tourist destinations. Bumthang is distinctly alpine — buckwheat and barley grow where rice cannot. Winters are harsh with temperatures regularly below -5°C at night. The region is extraordinarily beautiful in autumn (September–November) when the birch forests turn golden. The Jambay Lhakhang Drup festival (October/November) is one of Bhutan's most sacred and atmospheric. Best months: April–May and September–November.
Haa Valley (2,670m)
Similar to Bumthang in its highland character but slightly more accessible from Paro. Cold in winter with significant snowfall. The Haa Summer Festival (July) celebrates local culture when the valley is green and vivid. Best months: April–June and September–October.
Eastern Bhutan — Mongar, Trashigang (1,700–1,800m)
Eastern Bhutan sits lower than the central valleys and tends to be slightly warmer and drier. The eastern districts are less visited but have their own festival calendar running November–December. The drive east crosses Thrumshingla National Park (3,780m) — warm valleys give way to pine and rhododendron forest at the pass before descending again. Best months: October–November and March–April.
Southern Bhutan — Phuntsholing, Gelephu, Samdrup Jongkhar (200–500m)
The southern border towns are subtropical — warm and humid year-round, with temperatures regularly reaching 35°C in summer. Monsoon (June–September) is intense in the south, with heavy rainfall. These towns are entry/exit points for land travel from India rather than tourist destinations, but visitors spending time here should pack for subtropical conditions. Best months: November–February.
Gasa (2,700m)
Gasa's mountain location makes it significantly colder than Punakha despite being only 47km to the north — cold air flows south from the Tibetan Plateau. Summer (June–August) is cool and rainy. The best months are April–June and September–November. October is festival season (Royal Highland Festival). Winter (December–February) is cold but clear — the hot springs at Gasa Tshachu are at their most appealing in this season.
What to Pack by Season
Bhutan Weather — FAQs
What is the weather like in Bhutan in April?
April is one of the best months to visit Bhutan. Temperatures in Paro and Thimphu reach 20–22°C during the day, dropping to 8–10°C at night. Skies are clear, rhododendrons are in full bloom, and the Paro Tsechu festival typically falls in March or April. Punakha is warmer at 26–28°C. Conditions are perfect for sightseeing, trekking, and festivals.
Does it snow in Bhutan?
Yes — snow falls in Paro, Thimphu, and especially Bumthang between December and February. Heavy snowfall occasionally closes mountain roads for short periods. High passes used for trekking are snowbound from October/November through April. The main tourist circuit remains accessible year-round, though winter driving requires care.
Is it worth visiting Bhutan during the monsoon?
It can be, with the right expectations. The landscapes are extraordinarily lush and green, prices are lower, and the Haa Summer Festival (July) is a genuine highlight. However, trekking is not recommended due to slippery trails and leeches, mountain views are often obscured by cloud, and some roads can be affected by landslides. Cultural tours work well in monsoon; adventure activities less so.
How cold does Bhutan get in winter?
In Thimphu and Paro, winter nights regularly drop to -2°C to -5°C, with daytime temperatures of 10–13°C in December and January. Bumthang nights can reach -8°C to -10°C. Punakha stays milder at 4–8°C at night. Pack thermals, a warm jacket, hat and gloves for any December–February visit.
Trekking Weather in Bhutan
Trekking seasons in Bhutan are tightly linked to the monsoon. The two best trekking windows are March–May (spring — rhododendrons in full bloom, trails dry, views clear) and September–November (autumn — crystal-clear post-monsoon skies, golden foliage, ideal conditions). High-altitude routes like the Jomolhari Trek (4,890m maximum) and the Snowman Trek (5,300m maximum) require the October or spring window specifically — high passes are snowbound from late November through April.
