The best time to visit Dehradun is either October to November or February to April, when daytime temperatures sit between 20°C and 30°C, skies are clear, and rain is under 60mm a month. July and August are the months to avoid unless you’re fine with daily downpours, and May and June push past 35°C. This guide breaks down the trade-offs by season with specific dates, prices, and crowd levels.
Best Time to Visit Dehradun: October to November
October and November give you the clearest weather of the year, with 29°C (84°F) highs in October cooling to 25°C (77°F) by late November and nights around 10°C to 16°C. Rain is minimal, at 60mm in October and about 10mm in November. This is the best window for the Mussoorie viewpoint and for the Forest Research Institute grounds. Hotel rates are mid-range because the Indian school break and domestic rush have passed. Book the hill-station day trips early, since this is a busy weekend-travel period for Delhi residents, and pair the clear skies with the things to do in Dehradun list.
Best Time to Visit Dehradun: February to April
February to April is the other prime window. February starts at 23°C (73°F) and April ends near 33°C (91°F), with nights between 8°C and 17°C. This period covers Holi in March and the Jhanda Mela fair at Guru Ram Rai Darbar, which draws thousands of pilgrims and runs for about five days after Holi. Early April is also the best time for a Mussoorie trip before the May crowds arrive. Expect higher hotel prices during the March school holidays, so book at least a month ahead. For where to base yourself, see the Dehradun neighborhoods guide.
Best Time to Visit Dehradun: The Monsoon (July to September)
July and August are the wettest months, with 525mm to 560mm of rain each, and September brings about 260mm. You’ll pay the lowest room rates of the year in these months, and the valley turns green, but landslides can close the Mussoorie road for short stretches and outdoor attractions are wet. If you do visit, keep indoor sites like the Mindrolling Monastery stupa on your itinerary and confirm road conditions before heading to the hills. This is also when the Dehradun weather by month data shows humidity peaking above 85%.
Best Time to Visit Dehradun: Summer (May to June)
May and June hit 35°C to 36°C (95°F to 97°F) and are the hottest months, though humidity is lower than the monsoon. Prices stay moderate because most domestic travelers head straight up to Mussoorie and Rishikesh rather than staying in the valley. Avoid the midday hours of 12:00 to 16:00 and plan early-morning or late-afternoon sightseeing. This is also the peak season for the Dehradun events and festivals calendar in the nearby hill towns, which host their summer festivals in May and June.
Best Time to Visit Dehradun: Winter (December to January)
December and January bring 20°C to 21°C (68°F to 70°F) days and 5°C to 6°C (41°F to 43°F) nights, with morning fog that can delay the morning trains to Delhi. It’s quiet, and rates are low, but the fog cuts into sightseeing and drives on the Mussoorie road can be slow. If you want snow, this is the season to head up to Mussoorie or Auli. Whatever season you pick, use the where to stay in Dehradun guide to match your base to the weather, and the Dehradun travel tips guide for the hill drives.
