When you picture winter, maybe you imagine snow and biting cold, but Brazzaville’s idea of winter is something else entirely. Sitting just south of the equator, this city has a tropical savanna climate, so its “winter” actually lines up with the Northern Hemisphere’s summer.
In Brazzaville, winter means dry skies, steady warmth, and some of the year’s most comfortable weather.
From June to August, rainfall drops off sharply. Humidity lets up, the air feels lighter, and the sun keeps shining, so being outside feels a lot more pleasant.
Temperatures stay warm and steady, so you won’t deal with big swings like you might elsewhere.
This mix of dry air, gentle breezes, and reliable warmth shapes daily life and travel plans.
If you’re hoping to understand the climate or plan when to visit, knowing what Brazzaville’s winter really feels like helps you set realistic expectations.
Overview of Brazzaville’s Climate
Brazzaville has a tropical savanna climate, and it stays warm all year.
Rainfall and humidity change a lot more than temperature, creating clear wet and dry periods that shape how people live and travel.
Tropical Climate Characteristics
Brazzaville’s weather stays reliably warm year-round.
Average highs sit between 29°C and 33°C (84°F–91°F), and lows hover near 21°C (70°F).
That’s thanks to its spot near the equator.
Humidity really changes how the weather feels.
Levels dip to about 55% in the dry months but can soar over 80% in the wet season, making the air feel heavy and sticky at times.
Rainfall adds up to about 1,000–1,100 mm each year, with most of it pouring down during the rainy season.
Sunshine is pretty generous, averaging 7 to 9 hours a day, though clouds roll in more often during the wetter months.
Seasonal Variations
Brazzaville’s year splits into two main seasons: a wet season from October to May and a dry season from June to September.
During the wet months, rainfall peaks in November, sometimes topping 170 mm, and humidity climbs.
Frequent showers and muddy ground often make outdoor activities tough.
The dry season brings almost no rain, especially in July, which sometimes gets just 2 mm.
Temperatures stay high, but with lower humidity and clearer skies, these months are much better for travel and being outside.
Daily weather shifts are pretty minor.
You won’t see big temperature swings from day to night—just a change in how wet or dry the air feels.
Geographic and Environmental Factors
Brazzaville sits right on the Congo River at about 310 meters (1,020 feet) above sea level.
This slight elevation helps keep things warm but not unbearably hot.
Its spot near the equator means daylight hours barely change, averaging about 12 hours per day all year.
That steadiness keeps temperatures consistent but also brings high humidity.
The river basin and thick vegetation nearby affect rainfall.
Moist air from the Atlantic Ocean drifts in, fueling heavy rains during the wet season.
When wind patterns shift, less moisture comes in, so the dry season brings clearer skies and drier air.
Defining Winter in Brazzaville
Winter in Brazzaville isn’t cold or snowy like in temperate places.
Instead, it’s the driest stretch of the year, with less rain, lower humidity, and just a hint of cooler air compared to the wet months.
Months Considered Winter
People in Brazzaville call winter the dry season, which runs from June through August.
During this time, rainfall drops sharply, sometimes down to just 2–11 mm per month—the driest time of year.
Temperatures stay warm, with highs around 30–32°C (86–90°F) and lows near 21°C (70°F).
The heat sticks around, but humidity drops to 55–65%, so the air feels a bit lighter.
Weather gets more predictable.
Skies are usually clearer, sunshine averages about 7–9 hours per day, and visibility stays near 10 km (6.2 mi).
Winds pick up a little, averaging 7–9 km/h, which can make things feel milder even when it’s hot.
Travelers find this season the best for outdoor plans, since heavy rains and muddy roads basically disappear.
Comparison to Traditional Winter Seasons
If you compare Brazzaville’s winter to Europe or North America, it’s a whole different story.
You get steady warmth and dryness instead of cold air and frost.
The lowest temperatures rarely dip below 20°C (68°F), so heavy jackets stay in the closet.
No snow, no ice—just a long break from the rain.
That dry climate stands out against Brazzaville’s rainy months, when a single month can bring over 150 mm of precipitation.
You could call Brazzaville’s winter a “dry summer” more than a winter.
Here, the season is all about dryness, not cold.
Average Winter Temperatures
Winter in Brazzaville means steady warmth and only small changes between day and night.
Rainfall drops off, but the air stays humid, and temperatures barely budge across the season.
Daytime Highs and Nighttime Lows
Most winter days hit highs around 82–84°F (28–29°C).
Highs rarely fall below 77°F (25°C) or go above 91°F (33°C).
The hottest afternoons usually show up in early June, then things cool slightly into July.
At night, lows average about 67–69°F (19–21°C).
They almost never drop below 64°F (18°C) or climb above 74°F (23°C).
Since the difference between day and night is small, you get a steady, comfortable feel.
This balance makes winter feel more predictable than the wetter months.
Evenings are usually pleasant enough for being outside without bundling up.
Temperature Trends by Month
From June to August, temperatures cool off a bit, then warm up again.
- June: Highs near 84°F (29°C), lows around 69°F (21°C). The dry season really kicks in.
- July: Highs dip to about 82°F (28°C), lows near 67°F (19°C). This is usually the coolest stretch of the year.
- August: Highs climb back to around 84°F (29°C), with lows holding near 68°F (20°C).
These changes aren’t huge, but you’ll notice July feeling a bit cooler, while June and August are a little warmer.
Notable Temperature Extremes
The coldest day usually lands in mid‑July, with averages from 67°F (19°C) at night to 82°F (28°C) during the day.
Even then, the weather stays mild compared to most other places.
Early June sometimes brings the warmest afternoons, hitting up to 90–91°F (32–33°C).
Those hot spells aren’t common, but with humidity, the air can feel warmer.
Brazzaville never gets freezing weather.
You won’t see frost or extreme cold, which makes winter travel and outdoor plans a lot easier.
Winter Precipitation Patterns
In Brazzaville’s winter, rainfall drops sharply compared to the rest of the year.
You get drier air, fewer rainy days, and a humidity drop that makes being outdoors much more comfortable.
Rainfall Amounts
From June to August, Brazzaville sees its driest weather.
Rainfall slides down from about 41 mm in June to just 2 mm in July, then edges back up to around 7 mm in August.
That’s a huge change from the wet season, where totals can easily top 100 mm.
This low rainfall is classic for the tropical savanna climate (Aw), with its clear split between dry and wet times.
If you’re visiting, you probably won’t have to worry about heavy downpours.
Most days stay dry, and if it does rain, it’s usually brief and light.
Rainy Days and Dry Spells
Rainy days get rare in Brazzaville’s winter.
July might only see rain on 1–2 days.
June and August have a couple more, but that’s still way less than the 20+ rainy days you get during the wet season.
This long dry spell gives you reliable weather for outdoor plans.
Roads stay dry, paths are less muddy, and river levels even out, making travel easier.
If you look at months like May or September, you’ll see the difference.
Those months bring back frequent showers, but the true winter months hold onto their dry streak.
Humidity Levels
Humidity drops alongside the rain.
While the wet months push relative humidity above 80%, winter brings it down to about 55–65%.
That makes the heat feel less stifling, even when highs reach 30–32°C (86–90°F).
Mornings and evenings feel more pleasant, and you notice less stickiness.
Lower humidity and almost no rain create a much nicer setting for walking, sightseeing, or just being outside.
If you’re sensitive to humidity, this is the best time to be in Brazzaville.
Sunshine and Cloud Cover During Winter
In winter, Brazzaville gets fewer hours of bright sunshine and sees more cloud cover than during other parts of the year.
Skies bounce between partly cloudy and overcast, which affects both daylight and visibility.
Average Daily Sunshine Hours
During winter, Brazzaville averages about 4 to 5 hours of sunshine per day.
July often sees the least, with roughly 4.2 hours, while June and August get a bit more.
Even though it’s the dry season, skies often look hazy.
Daylight lasts about 11 to 12 hours, but a lot of that is filtered by thin clouds.
So, days might feel dimmer than you’d expect.
If you’re planning outdoor activities, it’s smart to head out earlier, since skies are more likely to clear up in the morning.
Even with less sun, the light is strong, and UV levels stay high, so sun protection is still important.
| Month | Avg. Daily Sunshine |
|---|---|
| June | ~4.5 hours |
| July | ~4.2 hours |
| August | ~4.6 hours |
Typical Cloudiness
Cloud cover during winter usually ranges from partly cloudy to mostly cloudy.
Unlike the wet season, clouds are thinner and less stormy but still block out direct sunlight.
The sky changes quickly—clear spells come and go, replaced by haze or overcast stretches.
Humidity is lower than in the rainy months, so you won’t see those heavy, dark clouds as often.
Instead, lighter cloud layers give everything a softer, muted look.
This pattern affects visibility, especially in the mornings when haze can hang around.
If you’re hoping for bright, clear-sky photos, winter isn’t ideal, but it’s a great season for walking tours and exploring the city without the heat and stickiness of the wet months.
Other Winter Weather Factors
When winter rolls around in Brazzaville, you notice more than just less rain. Wind patterns shift a bit, and humidity changes mess with visibility and air quality.
These factors really affect how comfortable you feel outside. They even change how easy it is to get around the city.
Wind Speeds and Directions
Winter winds in Brazzaville get a little stronger than usual. Average speeds jump from about 4–6 km/h during the wet months up to 7–9 km/h between June and August.
Sometimes, gusts hit 12 km/h. That breeze can make the air feel cooler, even if it’s still close to 30°C.
Winds mostly blow in from the south or southeast. This brings in drier air, which cuts down on humidity and makes things feel less sticky than during the rainy season.
If you’re visiting, you might actually appreciate these breezes. Walking outside or browsing a market feels a lot better when the wind takes the edge off the heat.
But if dust bothers you, watch out. Stronger winds sometimes kick up particles, especially in open or dusty spots.
Air Quality and Visibility
Most of the year, you’ll get visibility around 10 km in Brazzaville, but winter makes it even more reliable. With hardly any rain, skies clear up, and you get longer stretches of sunshine.
Humidity drops to about 55–60% in winter, which takes away the muggy feeling you get in wetter months. The air feels drier, and it’s just nicer to be outside.
Air quality gets a bit better, too. With lower moisture, pollutants and dust spread out more easily. You’ll probably notice less smog or haze than during the rainy season.
If you’re into sightseeing, river cruises, or snapping photos, winter is honestly one of the best times here. You’ll get clear views and fewer sudden weather surprises.
How Brazzaville’s Winter Weather Compares Regionally
Winter in Brazzaville means warm days, cooler nights, and a sharp drop in rain. These conditions really set it apart from other parts of the Republic of Congo. The city’s spot near the equator shapes a lot of its seasonal climate.
Contrast with Other Cities in Republic of Congo
Compare Brazzaville to Pointe-Noire on the coast and you’ll see some big differences. Pointe-Noire usually stays cooler and more humid in winter, thanks to the ocean. Daily highs there sit a bit lower than in Brazzaville, and the air feels heavier.
If you head inland to a city like Impfondo in the northern rainforest, you’ll find it’s still pretty wet. Rainfall doesn’t drop as much as it does in Brazzaville, and you’ll run into more showers and higher humidity up north.
Brazzaville’s winter feels drier and just more comfortable for being outside than these other regions. The mix of less rain and steady warmth makes the capital’s climate one of the most predictable in the country.
Key differences at a glance:
- Brazzaville: Warm, dry, less humid
- Pointe-Noire: Cooler, humid, ocean influence
- Impfondo: Wetter, high humidity, persistent rains
Impact of Proximity to the Equator
Brazzaville sits just south of the equator, so you won’t notice big swings in temperature from season to season. Instead, rainfall drops off sharply in winter, and that’s what really marks the change.
Even though the average highs stick close to 28–30°C (82–86°F), the dry season still feels different.
Day length barely changes, honestly—it’s just a matter of minutes between June and August. You won’t get those long, dark winter nights you’d find farther from the equator.
Sunrise and sunset times shift only a little, so daylight stays steady for daily routines.
Humidity shows the equatorial influence too. It’s always there, but during winter, it lets up compared to the heavier, wetter months.
You might still feel a bit of mugginess, but lower dew points make the air more manageable.
That mix of steady warmth, reliable daylight, and less rain really shapes what winter feels like in Brazzaville.
