Climate and monthly weather forecast
Guinea

Situated on the western coast of Africa, Guinea is a country defined by its tropical monsoon climate. Bordered by the Atlantic Ocean to the west, this geographical location plays a significant role in the country's climate, bringing about considerable levels of rainfall during the rainy season.
