Climate & when to go
Guinea is one of the wettest countries in West Africa – Conakry receives over 4m of rain, half of it in July and August, while the central mountainous region receives about 2m, more evenly distributed between June and October. Temperatures average 30°C along the coast, where it is always humid, and can fall to 10°C and below at night in Mali-ville and other highland areas during winter.
The best time to visit is November and December, after the rains but before the dusty harmattan winds spoil the views. The rains sometimes make minor roads impassable, though there’s something to be said for visiting the Fouta Djalon when it’s wet. The rains, which generally don’t last very long, make the waterfalls more explosive and the countryside more verdant, while the clouds lower the daytime temperatures.
