Rain season
Chennai's primary rain comes from the northeast monsoon October–December, making it unusual among Indian cities where the southwest monsoon dominates. Cyclones forming in the Bay of Bengal are a real risk October–November and can bring extreme rainfall in short windows. The southwest monsoon (June–September) passes mostly to the west, leaving Chennai relatively dry.
