The Gambia's peak tourist season roughly coincides with the coastal dry season, which lasts around eight months from mid-October to mid-June,
when the rainy season starts.
December and January see the highest concentration of visitors. It is not unusual to have weeks of unbroken sunshine at this time, but there
can sometimes be grey days and chilly nights. By March, the up-country landscape is a near uniform golden brown and hazy with airborne dust; the
last three months of the dry season are normally totally rainless. While daytime temperatures in the resort areas vary little all year, humidity
fluctuates considerably, rocketing at the end of the dry season and remaining high until October - nights can be very sticky from June to September.
The country gets around 1300 millimetres (51 inches) of rain from mid-June to mid-October - nearly double London's yearly average - most of it falling
at night, with August by far the rainiest month. The malaria risk is higher than usual during the rains, and some roads are waterlogged; however birds,
flowers and fresh vegetation are all abundant at this time, mangoes are in season, the sea is at its warmest, and, between the spectacular thunderstorms,
the days are bright and clear.
