Like many parts of India, the climate of Kerala is tropical with humidity. For most parts of the year, the temperature remains around 33 degree centigrade. It is during the winter months (October-January) when the temperature comes down to around 21 degree centigrade. Thus, the warm, moist and tropical climate of Kerala recommends light cotton clothes. If you are traveling to Kerala during the Monsoon season, you must take care of waterproofing and make arrangements for the same. Besides the light cotton clothes/outfits, one must take hats, sunglasses, sunscreen lotion to protect the skin from sun.
