In January, Dharamsala weather is cold and temperatures can plummet to below freezing. Even in March, when the weather down in Delhi is very hot, tourists will need a heavy winter coat in Dharamshala.
Summers: While in summers i.e. May and June, temperatures can reach upto 38°C.
Monsoon season is from July to September and is very wet. Monsoon season offers views of the cleanly washed forest like none other, and low hotel rates due to few tourists.
The peak tourist season in Dharamsala is between March and June, but it is very busy as most tourist flock to avoid the heat of the lower plains. Throughout the year there are good seasons to visit - October and November with the cooler weather. Late February is a good time to catch the Tsuglagkhang Complex.
The off season is in December and January when it is very cold.
So, the best time to visit Dharamshala is between May to June and October – November.
