In Gabon, an African country crossed by the Equator, the climate is hot and humid all year round in the north and in inland areas, with a short dry season from June to August, while in the central and southern part of the coast, the temperature becomes cooler during the dry season. In the far south, the dry season is longer, and it goes from mid-May to mid-September.
The temperature varies little over the course of the year in the north and the center of the country: the warmest period is from January to May, when highs are around 30 °C (86 °F), while it drops a bit from June to September, hovering around 24/25 °C (75/77 °F) in the central and southern part of the coast and around 27/28 °C (81/82 °F) in inland areas.
Annual precipitation in most of the country ranges from 1,500 to 2,000 millimeters (60 to 79 inches), while it's close to 3,000 mm (118 in) in the northern part of the coast, where Libreville is located. In the northern inland areas, near the Equator (see Bitam, Oyem, Makakou), there are two rainy seasons, from March to May and from September to November, caused by the two zenith passages of the sun (that is, when it shines directly overhead in the sky at mid-day).
Much of Gabon is occupied by forests and mangroves, except the extreme east, which is occupied by the savannah. There are several national parks, designed to protect the biodiversity of the region.
The amount of sunshine is not great, and it's even worse in the dry season, from June to August, when the sky is often cloudy. The (relatively) sunniest period runs from December to February.
In the interior, there are hilly areas, where the heat is tempered by altitude. The highest peak in Gabon is Mount Bengoué, which is located in the northeast and is 1,070 meters (3,510 feet) high. In the center of the country, we find the Chaillu Mountains, whose highest peak is Mount Milondo, 1,020 meters (3,346 ft) high.


Here are the average temperatures of Bitam, situated in the far north, at 600 meters (2,000 feet) above sea level. Because of the altitude, the temperatures are a little lower than in the plains.

Best Time

The best time to visit Gabon is from June to mid-September, and in particular, the months of July and August, since they are the least rainy, and also the ones in which there have been no anomalies in the rains in the past. During this period, the heat is not excessive, but the humidity is high and the sky is often cloudy. Nights can be a little cool in inland areas, while during the day, due to the breeze the air can feel cooler on the coast, especially in the southern part.

What to pack

All year round, bring light clothes of natural fibers, a light sweatshirt for the evening, an umbrella or a light raincoat during the rainy season. From June to September, you can add a sweatshirt and a light jacket, especially on the central and southern part of the coast and in the hills of the interior.
