The climate of 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. Throughout the entire year, the country's mean temperature remains above 18°C (64.4°F). The weather in Guinea does not vary significantly in temperature, but it varies substantially in terms of rainfall, leading to distinct wet and dry seasons.
