Climate

The coastal region of Guinea and most of the inland has a tropical climate, which is relatively mild for the latitude. Climatic differences between various parts of the country are affected by the sun's journey north or south of the equator and the corresponding position of the intertropical convergence: the boundary between the dry northeasterly winds and the moist southwesterly winds.

In the north of the country, squalls occur in March and April, followed by occasional rain until August and September, when the rainfall reaches its peak. Elsewhere, there are two rainy seasons, from April to June and from September to November.

The harmattan, a dry desert wind, blows from the northeast from December to March lowering the humidity and causing hot days and cool nights. Temperatures range between 21°C and 32°C (70°F - 90°F), and in most areas, temperatures are highest in March and lowest in August after the rains. Variation between night and day temperatures is relatively small, but greater in the north, particularly in January, with the harmattan. Relative humidity varies between 50% and 80% and average rainfall ranges from 75 to 200 cm a year.
