The climate of Bujumbura
In a city nestled within the heart of Africa, the climate adheres to the Köppen climate classification as a tropical wet and dry, or savanna climate. Bujumbura, the capital city of Burundi, experiences a significant seasonal variation in the amount of rainfall, however, little variability in the temperature. Being near the equator, the city does not experience the traditional four seasons but alternates between the wet and dry periods.
The range of rainfall varies immensely, seeing values from a serene 9mm (0.35") in July to a torrential 167mm (6.57") in April. This dramatic contrast heralds the divide between the wet and dry seasons, providing the city with definite periods of growth and aridity. The number of days in which the city experiences rainfall ranges from a minimum of 7 days in July to a peak of 29 days in April, further highlighting the dichotomy between the wet and dry periods.
