The Climate of the municipality consists of two types: type I, which has two pronounced seasons, Dry – from December to May and Wet – from June to November. Maximum rain period is from June to September. Areas characterized by this climate type are generally exposed to the Southeast monsoon and get a fair share of the rainfall brought about by the tropical cyclones occurring especially during the maximum rain period. Type II, has no pronounced maximum rain period with a short dry season lasting from one to three months. This type is intermediate between the proceeding two types, although it resembles the first type more closely because it has a short dry season. Areas of this climate type are partly shielded from the Northwest monsoon but are exposed to the Southwest monsoon and are also benefited by the rainfall caused by the tropical cyclones.
