Gabon - Climate
Gabon has the moist, hot climate typical of tropical regions. The hottest month is January, with an average high at Libreville of 31° C (88° F ) and an average low of 23° C (73° F ). Average July temperatures in the capital range between 20° and 28° C (68° and 82° F ). From June to September there is virtually no rain but high humidity; there is occasional rain in December and January. During the remaining months, rainfall is heavy. The excessive rainfall is caused by the condensation of moist air resulting from the meeting, directly off the coast, of the cold Benguela Current from the south and the warm Guinea Current from the north. At Libreville, the average annual rainfall is more than 254 cm (100 in). Farther north on the coast, it is 381 cm (150 in).
