Overview of Fall Weather in Libreville

In Libreville, fall brings steady warmth, high humidity, and a sharp rise in rainfall.

You’ll notice consistent daylight hours, lots of cloud cover, and muggy conditions that don’t really let up.

Typical Fall Temperature Range

Temperatures in Libreville stay pretty stable during fall. Daily highs average around 83°F (28°C) and rarely stray outside the 79°F to 87°F (26°C to 31°C) range.

Nighttime lows usually sit close to 75°F (24°C), with barely any variation.

Because the range is so tight, you don’t need to worry about big swings between day and night. The air just stays warm and heavy, as humidity clings near 100%.

You won’t find crisp mornings or cool evenings here, not like in other places.

The Atlantic Ocean nearby helps keep temperatures from getting too high or too low. Water temperatures climb from about 78°F (25°C) to 82°F (28°C) through the season, adding to that humid, tropical vibe.

Seasonal Weather Patterns

Rainfall ramps up quickly as fall moves along. At the start of September, you’ve got about a 17% chance of rain on any given day, but by November that jumps to nearly 70%.

Rain usually shows up as heavy downpours, not gentle showers.

Monthly rainfall grows from about 1.4 inches (36 mm) in early fall to nearly 10 inches (250 mm) by late fall. November is usually the wettest, sometimes topping 13 inches (350 mm) in just a month.

Clouds get thicker, too. By mid-November, skies are mostly cloudy or overcast more than 80% of the time.

Sunshine is limited, though daylight hours stick at just over 12 hours each day.

Winds calm down a bit, averaging 6–7 mph, usually blowing in from the west. With the high humidity, the air feels heavy and still.

Comparison to Other Seasons

Compared to summer, fall is wetter and cloudier. Summer brings less rain, more clear skies, and slightly cooler nights.

Spring feels similar in temperature but the rain pattern is different. Spring rain is common, but not as heavy as in late fall.

Winter is drier and less cloudy, though temperatures barely budge all year.

Because Libreville sits near the equator, you don’t get the sharp seasonal changes you’d see in temperate places. The main difference between seasons is how much rain and cloud cover you get, not the temperature.

Temperature Trends and Variations

In Libreville, Gabon, fall temperatures stay warm and steady, with only small shifts between day and night.

You’ll notice the humidity stays constant, while rainfall and cloud cover really shape how the air feels.

Average Highs and Lows in Fall

During the fall months, daily high temperatures in Libreville average around 83°F (28°C). They rarely dip below 79°F (26°C) or climb above 87°F (31°C).

The warm nights keep things muggy, and you shouldn’t expect cooler evenings to offer much relief.

The difference between highs and lows is usually about 8°F (4°C). This small gap really shows how stable Libreville’s climate is.

Unlike many other places, you won’t see big swings between daytime heat and nighttime coolness.

Daily and Monthly Temperature Fluctuations

Day-to-day changes in Libreville are minimal. You might notice a little warming or cooling depending on the clouds or rain, but the overall pattern doesn’t really shift.

Thick humidity also makes the air temperature feel about the same from one day to the next.

Across the season, temperatures barely move. September, October, and November all share similar averages, with no big changes.

A typical day might start at 75°F (24°C) in the morning, climb to 83°F (28°C) by the afternoon, and settle back near 76°F (24°C) at night.

This rhythm repeats almost every day, creating a predictable and pretty uniform climate through the fall.

Rainfall and Precipitation Patterns

During fall in Libreville, rainfall is frequent and often intense. High precipitation totals are the norm, with a big jump from early to late fall.

Wet days are common, and the number of rainy days each month really shapes daily life outdoors.

Monthly Rainfall Totals in Fall

Rainfall in Libreville during fall is about as heavy as it gets all year. September usually brings around 200–250 mm of rain, while October goes higher, often over 300 mm.

November peaks at close to 370 mm, making it the wettest month.

These numbers mean you’ll see steady rain throughout fall, with November really standing out for its intensity. Temperatures stay warm, usually between 27°C and 29°C, which just adds to the humidity.

To put it in perspective:

Month Average Rainfall (mm) Typical Temperature (°C)
September ~200–250 27–28
October ~300+ 28–29
November ~370 29

The steady increase in rain makes planning outdoor activities in late fall tricky. You should expect heavy showers that can last for hours, especially in November.

Frequency of Wet Days

The number of wet days in Libreville climbs steadily through fall. September usually has about 15–18 rainy days, October jumps to around 20 days, and by November, you’re looking at 22 or more wet days.

That leaves only a handful of days without measurable rain.

Rain doesn’t just show up as light drizzles. Showers are often heavy, and thunderstorms happen pretty often.

Even on days when it doesn’t rain all day, a downpour can still mess up travel or outdoor plans.

With so many wet days and big monthly totals, the environment stays damp. Roads can flood, and humidity stays high, so it’s smart to prepare for few dry intervals.

Rain gear and flexible plans are key if you want to get around the city comfortably during this season.

Humidity and Cloud Cover

Libreville’s fall season brings high humidity that barely lets up, along with cloud cover that just keeps thickening.

You can expect muggy conditions nearly every day and skies that get more overcast as the weeks go by.

Relative Humidity Levels

Humidity in Libreville hovers near 100% all fall. Morning or night, you’ll feel the constant moisture in the air.

Unlike temperature, which does shift a bit between day and night, humidity levels barely move.

Because the dew point stays high, sweat doesn’t evaporate easily. This leaves the air feeling sticky and heavy.

If you’re outdoors, physical activity can feel more tiring in this kind of weather.

For travelers, this humidity affects indoor comfort too. Air conditioning or fans become pretty much essential, especially at night when the air stays damp.

Packing light, quick-drying clothes will help you adjust.

Seasonal Changes in Cloud Cover

Cloud cover thickens fast during fall. At the start of the season, skies are overcast or mostly cloudy about 63% of the time.

By November, it’s up to around 81%, peaking near mid-November at 83%.

You’ll get the clearest days closer to September, when there’s still about a 37% chance of partly clear skies.

As weeks pass, thick clouds take over, usually linked to the rising rainfall.

You’ll see fewer bright, sunny days as the season goes on. If you prefer clearer skies, early fall is your best bet.

Later months bring heavier cloud cover and a dimmer, moodier atmosphere.

Wind Speed and Atmospheric Conditions

During fall in Libreville, you’ll feel steady winds that stay moderate—not too strong, not too weak.

These winds mix with high humidity and cloud cover, shaping how warm or cool the city feels.

Average Fall Wind Speeds

Winds in Libreville during fall usually stay light to moderate. Average speeds run between 6 to 9 miles per hour (mph), or about 10 to 15 kilometers per hour (km/h).

Long-term records at Libreville Airport back up these seasonal patterns.

Wind direction often shifts thanks to the Atlantic coast. Breezes typically blow from the southwest or west, bringing in moist air.

That only adds to the already humid feel.

Because Libreville sits right on the coast, sea breezes help keep the heat in check during the day, even when skies are cloudy.

Month Avg Wind Speed (mph) Common Direction
September 7–8 Southwest
October 6–7 West-Southwest
November 8–9 West

Impact of Wind on Weather Experience

The steady winds take the edge off the heat and humidity. Even though daily highs often hit 82–84°F (28–29°C), the moving air gives you a little relief, especially near the coast.

Without wind, the humidity would feel much heavier.

Winds also influence cloud cover and rainfall. In fall, moist air blowing inland ups the chance of showers, especially in October and November.

This keeps the season damp, but it’s not usually stormy.

If you spend time outside, you’ll notice the winds help with the humidity but don’t make it disappear. For travelers, this means you can expect a warm but manageable atmosphere, as long as you plan for occasional rain and sticky conditions.

Daylight, Sunshine, and Sea Temperatures

In Libreville, daylight hours stay steady through fall, while sunshine shifts with the rainfall.

Meanwhile, the sea stays warm enough for swimming, with only small changes in temperature as the season goes on.

Hours of Daylight and Twilight

Because Libreville sits right near the equator, you’ll barely notice any change in day length during fall.

Each day brings about 12 hours of daylight, and sunrise and sunset times hardly move from September through November.

Twilight is short. Once the sun sets, darkness falls fast, which is just how it goes in equatorial regions.

This makes planning outdoor activities a bit easier, since daylight is predictable.

The shortest days are only a few minutes shorter than the longest, so you really won’t notice much difference.

In practical terms, you get daylight from about 6:00 a.m. to 6:00 p.m. all season long.

Average Sunshine Duration

Daylight hours pretty much stay the same, but actual sunshine duration really depends on how much cloud cover and rain you get. In September, you’ll probably notice more breaks in the clouds, while October and November tend to bring heavier rain and fewer sunny moments.

Libreville usually gets 3 to 6 hours of sunshine per day during the fall. October and November feel especially cloudy, with long stretches where the sky just stays gray.

Less sunshine can make things feel a bit gloomy and it definitely affects visibility and how comfortable it is to be outside. If you’re thinking about heading to the beach or going sightseeing, September usually gives you better reliable sunny periods than the months that follow.

Sea Temperature Trends in Fall

The Atlantic waters off Libreville stay warm all year, and honestly, fall doesn’t really break that pattern. In September, the average sea temperature sits around 79°F (26°C).

October brings a slight bump, with water temperatures hovering near 81°F (27°C). By the time November rolls in, you’ll see it hit about 82°F (28°C).

So, swimming and water sports? Totally doable any time during fall. As the season moves along, the water actually gets a bit warmer, which just makes it nicer if you want to stay out there longer.

Even with the rain and those cloudy days, the sea stays calm and pretty inviting. You’ll find the water almost never dips below the high 70s, so it works out well for both casual swimmers and anyone hoping to dive in for a while.
