The best time to visit Banjul is November to February, when the dry harmattan season delivers warm, sunny days (around 27–30 °C), low humidity, and the best conditions for birdwatching and river excursions. This is peak tourist season, particularly for European charter flights, so book accommodation in advance.
March to May is still dry but grows hotter and hazier as the harmattan dust thickens. Temperatures regularly exceed 35 °C by April and May, which can make city sightseeing uncomfortable.
June to October is the wet season. Heavy afternoon downpours are common, humidity is high, and some beach-focused hotels close or reduce services. However, this is also when The Gambia turns lush and green, birdlife is at its most active (breeding season brings rare species), and prices drop significantly. Malaria risk is higher during the wet months, so prophylactics and mosquito precautions are essential year-round but especially from June onwards.
