The short answer
Bhutan has two peak seasons, spring and autumn, and two quieter ones, winter and the monsoon. The SDF is the same in every month, so the season you pick changes the weather, the crowds, hotel rates and which festivals you can see, but not that daily fee.
Altitude makes a big difference within the country. Punakha sits at about 1,200 m and is warm even in winter, with oranges and rice. Thimphu and Paro sit at 2,200–2,400 m. Phobjikha and Bumthang are at 2,600–3,000 m and get hard frosts from November to March. One trip can cross all three climates in a day, so pack in layers whatever the month.
Weather also decides how much of the Himalaya you see. The great snow peaks on Bhutan's northern border, including Jomolhari and Gangkhar Puensum, are visible from Dochu La, Chele La and the flight into Paro only on clear days. Those come most often from October to January and least often in the monsoon.

Spring: flowers and festivals (Mar–May)
Spring is Bhutan's flower season. Rhododendrons bloom from March on the lower slopes and through April and May on the high passes such as Dochu La, Pele La and Chele La, along with magnolias and wild primulas. Days are mild in Paro and Thimphu and warm in Punakha. Haze can hide the high peaks on some days, especially in May.
Spring is also a good season for walking. The Druk Path trek between Paro and Thimphu and day hikes from Haa and Phobjikha are at their best from April to May, before the rain makes trails muddy. In Phobjikha, the cranes have left by spring, but the valley floor turns green and dwarf bamboo and wildflowers cover the slopes. Treks need a licensed trekking guide; check current status before you travel.
The Paro Tshechu falls in March or April. In 2026 it ran from 29 March to 2 April, and the 2027 dates are tentatively 18–22 March. On the last morning a giant thongdrel is unrolled on the dzong wall before dawn. Hotels in Paro fill months ahead for it, and some raise rates. Check current status before you travel, as festival dates are confirmed late.
Choosing the season for your trip
Match the month to what matters most to you, because no single season gives everything. Festival lovers have to accept crowds; crane watchers have to accept cold; photographers who want the peaks have to give up the flowers.
Indian travellers coming by road from Siliguri should be most careful about the monsoon, when the long highway from Phuentsholing is most often blocked. Families on school holidays in May and June will find Bhutan quieter than the Indian hill stations, and mostly pleasant until the heavier rain arrives in late June. For honeymoons, late October to early December combines clear skies, cool evenings and fewer festival crowds than early October.
- Mountain views and photography: October to January.
- Flowers and walks: April and May.
- Festivals: Paro Tshechu in spring, Thimphu Tshechu and Bumthang festivals in autumn, Dochu La in December.
- Black-necked cranes: late October to February in Phobjikha.
- Treks such as the Druk Path: April to May and late September to November.
- Lowest hotel prices: December to February outside holidays, and June to August.
Monsoon: green and quiet (Jun–Aug)
The southwest monsoon reaches Bhutan in June and lasts into September. Rain falls on most days, often in the afternoon and night, and cloud hides the mountains. The southern hills around Phuentsholing are among the wettest parts of the country, and landslides can block the highway to Thimphu for hours.
Monsoon travel still works for some people. Valleys are green, rice terraces in Punakha and Paro are at their best, crowds are thin and hotel rates are often lower. Leeches appear on forest trails. If you go, choose flights into Paro rather than the road from Phuentsholing, keep the route short, and leave a spare day before onward flights. Check current status before you travel.
Autumn: the clearest season (Sep–Nov)
From late September the monsoon clears, and October and November bring the most reliable blue skies of the year. The high peaks are often visible from Dochu La, Chele La and the flight into Paro. Rice terraces in Punakha turn gold before the harvest, and chillies dry on rooftops across the country.
Autumn is also the busiest festival season. The Thimphu Tshechu falls in September or October; in 2026 it is due on 21–23 September, with 2027 tentatively on 10–12 October. Bumthang's Jambay Lhakhang Drup and Jakar Tshechu usually fall in October or November. In Phobjikha, black-necked cranes arrive from about late October, and the Black-necked Crane Festival is held at Gangtey Goenpa on 11 November in recent years.
Expect higher hotel rates and full flights. Book four to six months ahead for October. If you want autumn weather without the busiest weeks, aim for the second half of November, when skies are usually still clear, the cranes have arrived and the main festivals are over.
Winter: clear, cold and good value (Dec–Feb)
Winter in Bhutan is dry and often brilliantly clear. Nights in Thimphu and Paro fall below freezing, and Phobjikha and Bumthang are colder still, but days in the sun are pleasant. Punakha stays mild, which is why the central monk body traditionally moves there for the winter. Snow falls a few times most winters on the passes, and occasionally in Thimphu and Paro.
Winter is the best season for value. Many hotels drop rates outside the holidays, and you share sites with few others. The cranes are in Phobjikha until about February. The Druk Wangyel Tshechu at Dochu La is held on 13 December, and the Punakha Drubchen and Tshechu usually fall in February or March.
Pack properly and ask about heating. Passes such as Chele La and Pele La can close for a day after snow. Check current status before you travel.
- Bring a down jacket, thermals, a warm hat and gloves.
- Ask hotels and homestays whether rooms have heaters or wood stoves.
- Plan Taktsang for late morning in winter, after the frost on the trail softens.
