Climate & Weather Guide in Sierra Leone

Sierra Leone has a hot, humid tropical climate with two main seasons: a rainy season from May to November and a dry season from December to April. Köppen-Geiger sources identify tropical rainforest, monsoon, and savanna climates across the country, reflecting wetter coastal and southern zones and somewhat drier inland areas. The country is relatively compact at about 72,325 km², so a few broad regional zones capture most of the climate variation. For residents and expats, the main practical realities are high humidity, consistently warm temperatures, and heavy rainfall in much of the country, especially near the coast.
