Mombasa's Climate
Mombasa lies right on the Indian Ocean coast in south-eastern Kenya, just south of the equator, giving it a hot, humid coastal tropical climate that varies little in temperature and mostly by rainfall. Being in the Southern Hemisphere, the hottest spell falls in January–March with daytime highs of 30–33°C; the main "long rains" run from April to June bringing heavy showers, while the "short rains" arrive around October–December. A cooler, drier stretch from June to September, shaped by the south-east monsoon, is the most pleasant time of year. Sea breezes and high humidity are a constant.
