Climate - Coimbatore (India)

The climate of Coimbatore (or Kovai) is tropical semi-arid, slightly tempered by altitude, with a dry period from December to April and a rainy period in October and November. In the other months, the rains are quite irregular, and are generally not abundant. Temperatures are high all year round, although they drop a bit from November to January.
The city is located in southwest India, in the state of Tamil Nadu, at 11 degrees north latitude and 400 meters (4,265 feet) above sea level. To the west are the Western Ghats, with Mount Elivai Mala, 2,088 meters (6,850 feet) high, while to the north-west is the city of Ootacamund.
We are in the south-eastern side of India, where the summer monsoon does not arrive because it is hindered by the Western Ghats. Instead, the rains increase in October and November, during the northeast monsoon period.
Coimbatore is in the path of tropical cyclones. Typically, cyclones occur from April to December, although the extreme south of India is normally affected only in November and December. In any case, since the sea is warm all year round, in theory they can also form from January to March, perhaps in light form (as tropical storms).

The average temperature of the coldest month (December) is of 24.6 °C (76.3 °F), that of the warmest month (April) is of 30.1 °C (86.2 °F). Here are the average temperatures.
