Unlike the cooler months mid-year, winter temperatures stay steady and don’t dip below the mid-70s. You won’t get the slight relief from humidity that sometimes comes in July.
If you compare winter to spring or autumn, the main difference is the rain. Winter shifts from the heavy rains of late fall toward lighter showers in early spring, keeping things warm but not as extreme as the wettest months.

Rainfall and Humidity During Winter
Libreville’s winter months come with steady rainfall and high humidity. Daytime temperatures might be a bit cooler compared to the rest of the year, but the air still feels heavy with moisture.
Average Precipitation Levels
Rainfall in Libreville during winter is still significant, especially in October and November. October averages about 439 mm, and November can reach 469 mm, making these some of the wettest months of the year.
December stays wet too, with around 288 mm of rain.
These amounts are much higher than what you see in June, July, or August, when rain is scarce.
If you’re planning to be outside, get ready for frequent downpours—they’re usually intense but don’t last long.
Streets can flood quickly, and travel delays happen often.
Number of Rainy Days
Winter brings a lot of rainy days. In October, you’ll probably see rain on about 24 days.
November averages around 22 days, and December has about 17 days with measurable rain.
So, you’ll likely run into rain most days, though it won’t always last all day.
Showers often show up in the afternoon or evening, leaving mornings a bit drier.
Since rain spreads out over so many days, damp conditions stick around. Even when it’s not raining, surfaces stay wet and the ground can be soft.
Humidity Patterns in Winter
Humidity in Libreville stays high all winter, making things feel muggy. Most days, you’ll get high heat and humidity, with little relief even at night.
Nighttime temps usually stay above 22°C (72°F), so the air doesn’t cool off much.
Heavy rainfall and warm ocean air keep moisture levels up. You might notice clothes and bedding dry slowly, and it’s easy for indoor spaces to feel sticky if there’s not enough ventilation.
It helps to plan activities with breaks in cooler or air-conditioned places. Many travelers like to do outdoor stuff in the morning before the humidity peaks later.
Sunshine and Daylight Hours
In winter, Libreville gets fewer hours of sunshine compared to the rest of the year. Clouds and rain cut down visibility, but daylight still holds steady since Gabon’s close to the equator.
Average Daily Sunshine
Libreville averages about 3 to 4.5 hours of direct sunshine per day in winter. July and August usually have the least, sometimes dropping to 3 hours.
This drop comes from dry season cloudiness that blocks sunlight, even when it’s not raining.
Unlike the summer months, when sunshine can top 5 hours a day, winter skies often stay hazy.
If you’re planning outdoor activities, expect more overcast mornings and shorter sunny spells in the afternoon.
Lower sunshine totals can make the city feel less warm, even with air temps around 25–27°C.
Quick reference:
| Month | Average Daily Sunshine (hrs) |
|---|---|
| June | ~4.0 |
| July | ~3.0 |
| August | ~3.5 |
Length of Daylight
Libreville’s spot near the equator means daylight hours barely change year-round. In winter, you still get about 12 hours of daylight every day, with sunrise near 6:30 a.m. and sunset around 6:30 p.m.
This regularity makes planning your day pretty easy. Unlike higher-latitude places, you don’t see big jumps in daylight between seasons.
Even though the sun’s up for half the day, the low sunshine hours and frequent clouds can make days feel dimmer than you’d expect.
You’ll get steady daylight, but not always bright skies.
Cloud Cover and Visibility
Cloud cover really defines Libreville’s winter weather. Skies are usually partly to mostly cloudy, which softens the sunlight.
Sometimes, coastal humidity and haze drop visibility, too.
During July and August, clouds can hang around most of the day. It doesn’t always mean heavy rain, but it does give the city a gray, muted feel.
If you’re visiting, expect limited clear-sky views and softer light for photos. Visibility on the ground stays fine for most things, but you might notice hazy long-distance views over the ocean or skyline.
Sea Water Temperatures and Coastal Conditions
The waters along Libreville’s coast stay warm all year, with only small seasonal changes.
You can count on good swimming and coastal activities even in the cooler winter months.
Average Sea Temperatures
In winter, sea temperatures in Libreville usually sit near 28–29°C (82–84°F). That’s plenty warm for swimming, even if it’s cloudy or breezy.
The warmest water often shows up in late winter and early spring, while the coolest readings come in July or August.
Even then, the water rarely drops below 26°C (79°F).
The coldest sea temperature ever recorded near Libreville was about 24.3°C (75.7°F), but that’s pretty unusual.
Most of the time, the water feels stable and inviting.
Gabon’s equatorial location keeps the Atlantic warm all year, since the ocean soaks up and holds heat. The difference between seasons is smaller than in coastal areas farther north or south.
| Season | Average °C | Average °F |
|---|---|---|
| Winter | 28.7°C | 83.6°F |
| Spring | 29.1°C | 84.4°F |
| Summer | 26.3°C | 79.4°F |
| Autumn | 27.4°C | 81.3°F |
Beach Weather in Winter
When you visit Libreville in winter, you’ll find beaches that are still great for swimming and relaxing. The warm water mixes with air temperatures around 25–26°C (77–79°F), so it feels pretty comfortable most days.
Rainfall happens pretty often, but showers usually end quickly and clear skies follow. You can usually count on getting some time at the beach each day.
Humidity can get high, especially after a rain shower. Luckily, sea breezes along the coast keep the air moving and make it easier to enjoy outdoor activities.
Daylight hours in winter stick close to 12 hours. That’s plenty of time for a swim, a walk, or just lounging by the shore.
You might see more clouds than in the dry season, but the sea stays calm and warm enough for swimming all year.
Wind and Other Weather Factors
Libreville’s winters stay warm and humid. Other weather details, like wind, air pressure, and the rare extreme, also shape your experience here. These factors change how comfortable it feels and affect your plans throughout the day.
Wind Speed and Direction
In winter, winds in Libreville stay light and steady. They average about 4 mph, so you won’t really notice strong gusts.
This gentle wind makes the city’s coastal vibe more pleasant than places with tough trade winds.
Winds usually blow in from the southwest, thanks to the Atlantic Ocean. That brings in moist air and keeps humidity pretty high.
Even though the breeze isn’t strong, it still helps cool things down a bit. You’ll feel it most by the shore, where there’s nothing blocking the wind.
Move inland, and the trees and buildings block the breeze, so it gets calmer.
If you’re traveling, this mild wind means you can plan outdoor activities without worrying about getting blown around. Even boat trips along the coast usually go smoothly during winter.
Atmospheric Pressure
Libreville’s air pressure in winter stays steady, averaging around 755 inHg. That stability means you don’t get rapid weather changes very often.
The steady pressure, along with the equatorial climate, creates a humid but balanced environment. You won’t see sudden storms pop up out of nowhere like in some places.
Planning outdoor events is less stressful, since shifts in pressure rarely cause surprises. Sometimes the air feels heavy, but it’s not usually a big problem.
Libreville sits near sea level, so you won’t notice much change in pressure whether you’re on the coast or a bit inland. The readings stay pretty much the same.
Weather Extremes and Unusual Events
Libreville rarely sees extreme weather in winter. Temperatures usually sit between 81°F and 84°F. You probably won’t spot frost, snow, or any real cold snaps.
Rain does fall, though it’s not nearly as intense as in the wettest months. Most showers come and go quickly, and a lot of the day stays dry.
Windstorms, cyclones, or hurricanes just don’t happen here. The city’s spot right on the equator keeps those big storms away since they tend to form much farther north or south.
Sometimes, you might get a sudden downpour or a gustier wind, but that’s about as wild as it gets. Honestly, most people find winter weather here steady, warm, and pretty easy to handle.
