Winter (October to March) is the best and most popular time to visit Kerala, when temperatures are pleasant (between 20 and 30 degrees celsius), and days are sunny and dry.
Prices and demand peak over the Christmas and New Year period, so book well in advance, or, better, come outside those dates.
Summer, from late March – June is sticky and humid, and not the best time to explore the backwaters due to the humidity and heat. It can be a good time to visit Kerala’s hill stations of Wayanad, Munnar and Thekkady, but book well in advance.
Kerala’s monsoon rains can be lashing and unforgiving, and last from sometime in June until October. If you’re travelling during this time, keep on top of local news for flooding or transport disruptions.
