Guinea's climate is tropical. On the coast it is hot and humid and there is heavy rainfall east of the Fouta Djallon Mountains. There is a rainy and a dry season (November to May). The rainy season usually begins in May and lasts until November; in the southern rainforest it usually begins in February. The rainy season reaches its peak in the months of July and August, with maximum temperatures generally expected to be between 28 and 35°C. The rainy season is usually the first to be rainy in the summer months. In the Fouta Djallon Mountains, temperatures can drop to as low as 6°C during the winter months. The coastal capital Conakry has an almost constant temperature between 24 and 32°C day and night, regardless of the dry and rainy seasons. Due to the high humidity, which can reach 98 percent, the climate is always perceived as humid and is therefore very tiring. The hardest months to endure are at the beginning and end of the rainy season (May/June and October/November) with its tropical thunderstorms, hurricane-like storms and sudden downpours.
The preferred travel time for Guinea is between December and April.
