Overview of Libreville’s Climate
Libreville, Gabon’s capital, stays warm all year. Temperatures barely change, but rainfall, humidity, and sunshine hours shift around and give the city its tropical feel.
Tropical Monsoon Climate Characteristics
Libreville sits in a tropical monsoon climate (Köppen: Am). That means high humidity and lots of rain most months. The average temperature for the year hangs close to 26°C (79°F), with only tiny differences between the warmest and coolest times.
Rainfall is no joke—about 2,700 mm (106 in) drops each year. Some months go over 400 mm, while the driest ones might only get 20 mm or less. Still, the air stays muggy all year.
Sunshine is limited compared to drier tropical places. You usually get 3–6 hours of sun each day, depending on the month. The UV index is extreme almost year-round, so sun protection matters, even if it’s cloudy.
This kind of climate keeps the landscape green and lush, but it does mean you’ll feel sticky most days.
Seasonal Weather Patterns
Libreville doesn’t really do the four-season thing. Instead, you’ll go through wet and dry periods.
- Long wet season: February to May, with March and April seeing the most rain.
- Short dry season: June to August, when things dry out a lot.
- Short wet season: September to November, with intense, frequent storms.
- Short dry break: December to January, which is less rainy but still humid.
During the dry months, days hit 26–27°C (79–81°F). Wet months get a bit hotter at 29–30°C (84–86°F). Nights stay warm, usually around 22–23°C (72–73°F).
Humidity barely drops, even in the dry season. But with less rain, it’s easier to get outside. The rainier months bring heavy showers that can mess with travel plans.
Location and Geographic Influences
Libreville sits right on the Atlantic coast of central Africa, just above the equator. Its low elevation (about 22 m/73 ft above sea level) and coastal spot play a big part in its weather.
Because it’s so close to the equator, you get almost equal day and night all year—about 12 hours of daylight daily. That keeps temperatures steady.
The Atlantic Ocean helps keep temperatures from getting too extreme, but it also pumps moisture into the air, which means lots of humidity and rain. Sea surface temperatures usually stick between 25–29°C (77–84°F), adding to the warm, muggy feeling.
Rainforests around the city recycle moisture back into the air. With the ocean and all that greenery, Libreville’s climate stays predictably tropical.
