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.
