No other Indian state between the Hymalayas and Kanyakumari in Tamil Nardu, the southernmost point on the peninsula, is so rich in water. In Kerala, the monsoon rain is absorbed by the mountains and the rainwater flows back down into the lowlands in more than 40 rivers.

Thousands of families plant rice in their flooded paddy fields. in this subtropical climate they can harvest two, sometimes even three crops a year.

With 120–140 rainy days per year, Kerala has a wet and maritime tropical climate influenced by the seasonal heavy rains of the southwest summer monsoon. In eastern Kerala, a drier tropical wet and dry climate prevails. Kerala's rainfall averages 3,107 mm annually. Kerala’s maximum daily temperature averages 36.7°C; the minimum is 19.8 °C. Mean annual temperatures range from 25.0–27.5 °C in the coastal lowlands to 20.0–22.5 °C in the highlands.

As can be seen from the rainfall graph, the best time to go to Kerala is outside of our summer. However, having toured the state in August and experienced very little rain and pleasent temperatures, it is obviously difficult to give exact advice.
