When is the best weather in Kerala? Monthly breakdown of temperature, rainfall, and sunshine hours — ranked by what actually matters for your trip.
Best month
December
The Kochi-Muziris Biennale opens and peak season begins — Kerala's most vibrant month.
↑The Kochi-Muziris Biennale opens in December — its opening weeks draw the international art world to Fort Kochi, creating an atmosphere unlike any other event in India. The installations occupy the Aspinwall House heritage compound, Baker's Bungalow, and Pepper House; the quality of international participation has grown each edition since 2012.
↑December's weather is essentially perfect: 31°C days, cool evenings at 22°C, virtually no rain, low humidity, and the backwaters glassy and still. Christmas celebrations in Kerala — a state with one of India's largest Christian populations — are genuinely festive, particularly in Kottayam and Fort Kochi's Santa Cruz Cathedral.
↑The full menu of Kerala experiences is available simultaneously: houseboats, beach resorts, hill stations, wildlife, and the cultural calendar are all operating at peak quality and reliability.
