Regional Climate Variations

Coastal and Central Regions

The Gambia's primary climate zone encompasses the entire country with a tropical savanna pattern. Banjul and surrounding coastal areas experience warm temperatures year-round, with the dry season (November-May) bringing average temperatures of 18-30°C and the wet season (June-October) reaching 23-33°C. Rainfall concentrates heavily during the monsoon months, with most precipitation occurring between June and October. The Sahel climate makes the region vulnerable to climate variability, including potential increases in windstorms, floods, and droughts.

The Gambia maintains a consistent tropical savanna climate across its small territory, with warm temperatures year-round and a clear division between dry and wet seasons. The dry season (November-May) provides cooler, more comfortable conditions, while the wet season (June-October) brings concentrated rainfall and higher humidity. Residents should prepare for increasing climate variability, including potential droughts and severe weather, as temperatures continue their upward trend.
