Overview of Mombasa’s climate

Mombasa has a tropical climate that is affected by its proximity to the Indian Ocean and its location near the equator. The city experiences warm temperatures throughout the year, with very little seasonal variation compared to inland areas of Kenya. The average daytime temperature is typically between 28°C and 32°C, while nighttime temperatures remain comfortably warm and rarely fall below 22°C.

High humidity, which is characteristic of coastal areas, also plays a role in the climate in Mombasa. Humidity levels increase during the rainy seasons but are moderated by the frequent sea breezes, which cool the air, particularly in the early mornings and evenings. These ocean winds make the heat more bearable for both locals and visitors.

The city of Mombasa has two rainy seasons: the long rains that occur between the months of March and May, and the short rains that occur during the months of October to November. Rainfall usually occurs in short, heavy showers rather than prolonged periods of rain. Overall, Mombasa’s climate is stable, warm, and favorable for tourism throughout the year.
