Cameroon is climatically divided into three parts. In the north of the country it is hot and dry with an average temperature of over 30 degrees. The total annual precipitation of about 500 to 700 mm per square meter falls during the rainy season. In the dry season, which lasts from October to April, there is a regular risk of drought. The highlands to the south, which adjoin it, have cooler annual mean temperatures of 22 degrees Celsius due to the topography, and during the rainy season from April to November also higher precipitation sums (for example 1500 mm in Ngaounderé). With annual precipitation of up to 11,000 mm, the mountainous region of Western Cameroon is even one of the regions with the highest rainfall on earth. The climate of the coastal plain in the south of the country is tropical and humid with an average annual temperature of about 25 degrees. The rainy season lasts from March to November, although the remaining months do not remain completely dry. In the seaside resort of Kribi there is an average rainfall of about 3000 mm per year.
Because of its climatic and scenic diversity, Cameroon is regarded as "the whole of Africa in one country". Despite the higher temperatures, the dry season is better suited for travelling, because during the rainy season, torrential downpours and flooded roads are to be expected.
