The mean maximum and minimum temperatures during summer and winter varies between 35°C to 18°C. highest temperature ever recorded is 41°C and lowest is 12°C.
Due to the presence of the mountain pass, major parts of the District benefit from the south – west monsoon in the months from June to August. After a warm, humid September, the regular monsoon starts from October lasting till early November.
These monsoons are brought about by the retreating North – eastern monsoon. The average annual rainfall is around 700 mm with the North East and the South West monsoons contributing to 47% and 28% respectively to the total rainfall.
Although this rainfall is not enough to sustain the needs of the city for the entire year, small rivers like the Siruvani and Atthikadavu fulfill the city’s water needs.
The soil is predominantly black, which is suitable for cotton cultivation, but it also has some red loamy soil. Coimbatore falls under the Class III / IV Seismic Zone, having experienced a 6.0 Richter scale earthquake in 1900.
The Salim Ali Centre for Ornithology and Natural History is located at Anaikatty in Coimbatore district.
