Summer in Baku means long, sunny days, warm temperatures, and steady winds rolling in from the Caspian Sea. Average highs usually fall between 25°C and 30°C (77°F to 86°F), and you’ll hardly see any rain—summer is easily the driest stretch of the year.
The mix of heat, low humidity, and breezes off the water makes it surprisingly comfortable to be outside. Honestly, it’s a good time to get out and enjoy the city.
Daylight hangs around well into the evening—sometimes you’ll get nearly 15 hours of sun in June and July. Beaches along the Caspian stay lively, and open-air cafes or seaside promenades fill up quickly.
The weather feels pretty reliable, so you can plan outdoor activities without much worry. That stability is a big plus.
But Baku’s famous winds definitely shape the summer vibe. These breezes cool things down, but sometimes they can surprise you with a gust or two.
This blend of warmth, dryness, and wind gives Baku’s summer its unique character. It’s worth digging into the details—temperatures, sunshine, wind, and rainfall all play their part.
Overview of Baku’s Summer Climate
Baku’s location on the Caspian Sea and its steppe climate really define its summers. Expect hot, dry weather, long daylight hours, and steady winds, with barely any rain.
Geographical Influences on Weather
Baku sits right on the west coast of the Caspian, just about 23 meters (76 feet) above sea level. That coastal spot keeps nighttime temperatures a bit cooler than what you’d get inland.
The city falls under the BSk (cold semi-arid/steppe) climate category. So, summers are hot and dry, winters are milder and a bit wetter.
The landscape around Baku is mostly semi-desert, which means even less rain. The Caspian Sea helps keep humidity levels in check.
Winds matter here. The Khazri (northern wind) and Gilavar (southern wind) swing in and out, changing temperatures and comfort. Usually, these breezes make the heat easier to handle, but sometimes they get pretty strong.
Because of all these factors, Baku gets less cloud cover in summer. There’s a ton of sunshine, and daylight can last up to 15 hours in June. That’s a big part of what makes Baku’s summer weather what it is.
Typical Summer Weather Patterns
From June through August, average daytime temperatures start around 22°C (72°F) in early June and climb to about 30°C (86°F) in July. Nights stay warm, rarely dipping below 20°C (68°F).
Rain is almost a non-event. July and August usually see just 4–6 mm of rain, and that’s spread over only a few days.
Humidity sits around 54–60%, so the heat doesn’t feel as sticky as it does in tropical places. By August, the Caspian Sea warms up to about 24–25°C (75–77°F), which draws swimmers.
Winds average 20–23 km/h (12–14 mph) through the summer. They cool the city but can kick up some dust on dry days.
With all this—long days, bright sun, and dry air—Baku’s summer feels clear and lively.
Average Summer Temperatures
Baku’s summer heat stays steady, but you’ll notice it gets hotter as the season goes on. Daytime highs rise, nights get warmer, and humidity slowly builds.
Monthly Temperature Ranges
Daily highs start around 79°F (26°C) in June. By late July and August, they often hit 85–89°F (29–32°C).
Nights follow along. In June, lows average 63°F (17°C), but by late July, you’re looking at 69–73°F (20–23°C). August nights rarely drop below 73°F (23°C).
The hottest stretch usually hits in late July and early August. Daytime highs push close to 89°F (32°C), and nights stay warm.
By the end of August, things cool just a bit, but it’s still summer-warm.
| Month | Avg High | Avg Low | Typical Range |
|---|---|---|---|
| June | 79°F / 26°C | 63°F / 17°C | 73–85°F (23–29°C) |

Daytime Versus Nighttime Temperatures
Baku’s daytime heat can get intense, but it rarely goes above 97°F (36°C). The sea helps keep things from getting too extreme, though warm winds from the north sometimes crank up the temperature.
Nights are mild. Even early in the season, you won’t see much below the low 60s. By late July, overnight lows usually stay above 70°F (21°C), which can feel a bit muggy.
Since the difference between day and night isn’t huge, you don’t get much cooling after sunset. If you’re visiting, plan your outdoor time for earlier in the day, and expect warm evenings—no jacket needed.
Sunshine and Daylight Hours
Baku’s summer climate offers long, bright days. The daylight hours shift as summer rolls along, but you’ll always have plenty of time to be outside.
Average Daily Sunshine
During summer, expect 9 to 11 hours of sunshine per day. July stands out as the sunniest month, with about 10.5 hours daily and over 300 hours for the month.
June and August aren’t far behind, averaging 9–10 hours of sunshine each day. That’s prime time for exploring or just relaxing along the coast.
Compared to other European cities, Baku gets more sun in midsummer. For example:
| City | July Daily Sunshine (hrs) |
|---|---|
| Baku | ~10.5 |
| Barcelona | ~9.5 |
| Reykjavík | ~6 |
With this much sun, you’ll want to think about sun protection, especially midday when the UV index climbs.
Day Length Variation
In June, around the solstice, Baku enjoys its longest days—about 15 hours of daylight. By late August, that drops to around 13 hours.
Sunrise in June comes just after 5:00 a.m., but by August, it’s closer to 6:00 a.m. Sunsets move from nearly 8:30 p.m. in June to about 7:30 p.m. in August.
Even as days shorten, you still get plenty of usable daylight. It’s great for sightseeing, outdoor dinners, or day trips out of town.
Wind and Breezes in Summer
Summer in Baku means steady winds, and they really shape daily life here. The strength and direction of these breezes matter—sometimes they’re refreshing, sometimes just a bit much.
Prevailing Wind Patterns
People call Baku the “City of Winds,” and summer proves why. July and August bring the strongest winds, with average speeds around 6 m/s (22 km/h or 13 mph). You’ll feel it all day long.
June is a little calmer, with averages closer to 5 m/s. Still, the breeze is always there and can change how you dress or plan your day.
Most of the time, winds blow from the north and northwest, pulling in cooler air from the Caspian. That helps take the edge off the heat, especially when it’s pushing into the mid-80s °F (around 29–30°C).
Humidity also feels less intense because of the wind, which is a relief in a coastal city.
Windy days aren’t all the same. Some are just breezy, others come with gusts that can make umbrellas or hats a challenge.
Impact of Wind Speed on Comfort
Wind in Baku during summer can be both a blessing and a hassle. At 6 m/s, you’ll see tree branches moving and feel a real cooling effect on your skin. That makes walking around much more pleasant.
But sometimes, the wind gets in the way. For example:
- Beach visits: Waves can get rough, so swimming isn’t always calm.
- Outdoor dining: Light items or umbrellas might not stay put.
- Sports: Ball games and cycling can get tricky with gusts.
When winds drop to 4–5 m/s, things feel more relaxed. Evenings can feel especially nice, with the breeze and cooler air.
If you’re planning to explore or hang out by the water, wear secure clothes and avoid carrying stuff that catches the wind. That way, you get the benefits without the headaches.
Rainfall and Humidity Levels
Summer in Baku is all about dry weather and only moderate humidity shifts. You’ll see barely any rain, and humidity drops compared to spring.
Precipitation Trends
Rain in summer is rare. July and August are the driest, with only 4–6 millimeters of rain on average. Usually, rain falls on just a few days—less than five per month.
You’ll probably go weeks without a drop. When it does rain, it’s usually light and over quickly.
Here’s a snapshot of average summer rainfall:
| Month | Avg Rainfall (mm) | Rainy Days |
|---|---|---|
| June | ~8–10 mm | 5–6 days |
| July | ~4 mm | 4–5 days |
| August | ~4 mm | 4–5 days |
With this kind of dry spell, your outdoor plans won’t get rained out. But sometimes, the wind can make the dry air feel even drier.
Humidity During Summer Months
Humidity in Baku stays lower in summer than any other time. July averages around 60%, which is as low as it gets here. June and August are a bit higher, usually 65–68%.
That’s a big drop from spring, when humidity can top 75%.
Mornings may feel a little more humid, but afternoons dry out as temperatures and winds pick up. If you’re outside all day, you’ll notice the difference.
Humidity at these levels is pretty manageable. You don’t get that heavy, sticky feeling you might find in tropical places, so summer outings are a lot more comfortable.
Temperature Extremes and Records
Baku’s climate swings from hot summers to chilly winters. The city gets long stretches of wind, and while most summer days feel comfortable, Baku has seen both record-setting heat and some unusually cool days that stand out in its weather history.
Record High Temperatures
Summers in Baku usually hit the mid-80s °F (about 29–31 °C). Sometimes, though, the city swelters under extreme heat, getting close to 97 °F (36 °C) during the hottest stretch.
July or August tends to bring these record highs. Dry air, a relentless sun, and barely any rain all team up to create those scorching days.
August stands out as the hottest month on average, with daily highs hovering near 89 °F (32 °C). Sure, it’s not quite desert-level heat, but the mix of humidity and steady winds makes it feel a lot heavier than the numbers suggest.
If you’re traveling, you’ll notice the difference between a typical hot day and one that breaks records. On those record highs, just being outside can wear you out fast, and you’ll probably find yourself searching for shade or a cool spot indoors.
Locals tend to plan around the peak heat, and honestly, it’s smart to do the same if you’re visiting in midsummer.
Record Low Temperatures
Winter in Baku feels long and pretty cold, especially if you compare it to those warm summer months. In January, average lows drop to about 36 °F (2 °C). Sometimes, though, the city actually hits temperatures below 29 °F (−2 °C) during its coldest years.
These record lows don’t happen often, but wow, they really show how quickly the weather can turn.
The coldest month is definitely January. On average, daily temperatures hover around 41 °F (5 °C). Strong winds blow in from the Caspian Sea and make everything feel even colder, especially after dark.
If you plan to spend time outside during winter, you’ll probably notice the impact of those record lows right away. Snowfall might be light, but the mix of chilly air and wind can get uncomfortable fast if you don’t bundle up.
Extreme cold days aren’t as common as those blazing summer highs, but they still play a big role in shaping Baku’s climate.
