The short answer
When to go to Dehradun
The most comfortable months are October and November and February to April, when days are dry and warm and nights are cool. December and January are cold in the mornings but clear. May and June are hot, and July to September brings some of northern India's heaviest rain, which makes Robber's Cave and Sahastradhara unsafe. Older travellers should avoid midday heat in May and June and the slippery monsoon months.
