What September feels like in Bangalore
September falls in Bangalore's wet season — the rainfall numbers rise clearly above the dry months. Warm daytime weather invites long lunches outside and evening strolls. The gap between afternoon and night is small, so nights stay warm and the temperature hardly changes after dark. Thick, humid air means clothes cling and the heat feels stronger than the number.
