India's weather is extremely varied, something you must take into account when planning your trip. The most influential feature of the subcontinent's climate is the wet season, or monsoon. This breaks on the Keralan coast at the end of May, working its way northeast across the country over the following month and a half.

The climate of most of Thailand is governed by three seasons: rainy (roughly June to October), caused by the southwest monsoon; cool (November to February); and hot (March to May). The cool season is the pleasantest time to visit and the most popular. Christmas is peak season, when accommodation gets booked way ahead and prices rise significantly.
