Weather in North of India differs from the South. The weather in the North is very pleasant between October and March, with January being on the cold side. Summers rfom April to July, can be very hot. The monsoons generally happen from July to September. In the South, it can be quite pleasant in the winter but never too cold unless in the mountains. Summers are hot with monsoons hitting earlier in May.
We usually plan our workshops between October and March so that most days are pleasant and nights cool making it ideal for plein-air and travel.
