Coimbatore's Climate
Coimbatore sits in Tamil Nadu, southern India, at the foot of the Western Ghats beside the Palghat Gap, giving it a tropical savanna climate that is noticeably milder than neighbouring plains cities. The hot season (March–May) is dry and sultry with daytime highs of 33–37°C, after which the southwest monsoon (June–September) brings showers and a cooling breeze funnelled through the gap. The main rains arrive with the northeast monsoon (October–November) in heavy bursts, while winter (December–February) is dry, cool and the pleasantest time of year.
