Spring in Baku always feels like a season of change. Cool March mornings gradually turn into mild, comfortable days by late May.
You’ll see average highs climb from the upper 40s °F (around 9°C) in early spring up to the upper 70s °F (about 26°C) as summer approaches. Nights warm up too, so by late spring, the city feels a lot more inviting.
Rain falls less often as spring goes on, and skies clear up more every month. By late May, sunshine takes over most days, and the longer daylight hours give you extra time to wander the city or stroll along the coast.
The Caspian Sea sits nearby, and it definitely shapes Baku’s weather. It moderates temperatures, and you’ll notice the breezes it brings, especially in spring. These shifts in temperature, rainfall, and daylight make the season feel fresh and pretty well-balanced. It’s a great time to see both Baku’s historic streets and its natural spots.
Spring Temperature Trends in Baku
Spring in Baku brings a steady warm-up, longer days, and a shift from chilly, damp March weather to much milder conditions by late May.
Daytime and nighttime temperatures both rise, and you’ll notice the difference compared to the extremes of winter or summer.
Average Daily Highs and Lows
During spring, daily high temperatures in Baku start around 9 °C (47 °F) in early March. By late May, highs reach about 26 °C (79 °F).
You won’t often see highs drop below 4 °C or shoot above 30 °C. Lows also climb, beginning near 3 °C (37 °F) in March and reaching about 17 °C (63 °F) by May’s end.
Nights usually stay above freezing, which marks the start of the growing season.
This steady rise makes spring one of the most comfortable times to experience Azerbaijan’s climate. You skip the sharp cold of winter and dodge the intense summer heat that can soar well above 30 °C.
Monthly Temperature Progression
If you check the monthly averages, the warming trend is obvious.
- March: Highs around 15 °C (59 °F), lows near 8 °C (46 °F).
- April: Highs about 18–20 °C (64–68 °F), lows up to 12 °C (54 °F).
- May: Highs average 21–22 °C (70–72 °F), lows at 16 °C (61 °F).
By late spring, many days feel like the start of summer. Daylight jumps by nearly 3.5 hours from March to May, and that extra light really pushes the warming trend.
You’ll find more time for outdoor activities, with comfortable days and mild evenings.
Comparison to Other Seasons
Spring temperatures in Baku land right between winter’s cold and summer’s heat. In winter, highs average just 6–7 °C, and lows can dip close to freezing.
Summer is a whole different story, with highs of 30 °C or more and warm nights that rarely fall below 20 °C.
Spring warms up faster than autumn and usually has fewer cloudy, wet days. Autumn cools down slowly, but spring jumps into warmth.
This quick transition makes spring stand out in Azerbaijan’s climate, offering milder weather than either end of the year. It’s honestly one of the best times to visit.
Rainfall and Precipitation Patterns
Spring in Baku usually brings light to moderate rain, but most days stay dry. Precipitation stays limited compared to many other cities, though you’ll see some differences between March, April, and May.
Frequency of Wet Days
You’ll notice that wet days are pretty rare in spring. March tends to have the most, with about 5–6 days of measurable rain.
By April, rainy days drop a bit, and May usually sees only 3–4. Baku’s semi-arid climate means you’ll get long stretches of dry weather between showers.
Even when it rains, it’s often just a quick burst, not an all-day thing. That makes planning outdoor activities less of a headache.
Wind often comes with these showers, making the air feel cooler than the thermometer says. Since rainfall is scattered and infrequent, you’ll get more dry days than wet ones all season.
Monthly Rainfall Totals
Rainfall totals in Baku stay low, especially compared to humid regions. Here’s a quick look:
| Month | Average Rainfall (mm) | Rainy Days (approx.) |
|---|---|---|
| March | 20–25 mm | 5–6 days |
| April | 15–20 mm | 4–5 days |
| May | 10–15 mm | 3–4 days |
Rain tapers off as spring moves along. By late May, Baku starts to shift toward its dry summer pattern.
Most rain falls lightly, just a few millimeters at a time. Heavy downpours are rare, and if they do show up, they’re short and local.
You won’t need to worry about flooding or waterlogged streets this time of year.
Snow and Mixed Precipitation
Snow after February is unusual in Baku, but sometimes a dusting lingers into early March.
If snow does appear, it melts quickly as days warm up. By April, snow is pretty much gone, and you might get the odd mix of rain and sleet, though that’s not common.
By mid-spring, Baku’s climate turns mostly dry and windy. You can expect rain-free days, with just a slim chance of leftover wintry weather at the very beginning of the season.
Humidity and Cloud Cover
Spring air in Baku slowly loses its dampness, and the skies clear up more as summer nears.
These changes affect how the weather feels and how much sun you get each day.
Relative Humidity Changes
March brings the year’s highest humidity, averaging around 77%. That level of moisture, paired with steady winds, can make cool temperatures feel a bit raw.
By April, humidity drops into the low 70s. The air starts to feel lighter, and outdoor activities become more pleasant.
Nights might stay a bit damp, but days get more comfortable. By May, average humidity falls closer to 65%.
With rising temperatures, the weather feels warmer but not sticky. It’s a nice balance—warmth without the muggy feeling.
Cloud Cover Decrease Through Spring
March skies often look partly cloudy, with a good share of overcast days. That keeps things cooler and can make the month feel a bit gray.
In April, clouds start to break up. You’ll get more sun, though scattered clouds still float by. The mix keeps days mild.
By May, clouds thin out even more, and clear days show up more often. The stronger sun and lighter clouds make Baku feel brighter and more open.
This trend means summer’s sunny, dry season isn’t far away.
Sunshine and Daylight Hours
Spring in Baku brings longer days and a lot more sunshine compared to winter. You’ll notice daylight stretching out, and sunrise and sunset times shift in ways that give you more time outdoors.
Daylight Duration Increase
From March to May, Baku’s daylight grows by several hours. Early March gives you about 11 hours of daylight.
By late May, you’re looking at nearly 15 hours. That’s a big, steady change.
Each week adds a few more minutes of light. It’s great for sightseeing or just enjoying the city.
Sunshine hours rise too—from about 4–5 hours per day in March to nearly 8–9 hours in May.
Baku’s spot on the Caspian’s western shore helps. The city gets longer spring days than some places at similar latitudes, and the semi-arid climate means a bit more sun.
Sunrise and Sunset Times
In March, sunrise is around 7:00 AM, and sunset lands near 6:30 PM.
By late May, the sun comes up at about 5:20 AM, and sunset stretches past 8:00 PM. That means brighter mornings and much later evenings.
If you like evening walks along the waterfront or hanging out at outdoor cafés, the later sunsets are perfect. You’ll also need less artificial light in the evenings, which just makes the city feel more alive.
Here’s a quick outline:
| Month | Sunrise | Sunset | Daylight Length |
|---|---|---|---|
| March | ~07:00 | ~18:30 | ~11 hrs |
| April | ~06:20 | ~19:30 | ~13 hrs |
| May | ~05:20 | ~20:10 | ~15 hrs |
These longer days give you more choices for how to spend your time and enjoy Baku’s spring weather.
Caspian Sea Influence on Baku’s Spring
The Caspian Sea shapes Baku’s spring weather by moderating temperatures and changing wind patterns.
Its effect stands out in spring, when the city shifts from winter’s chill to summer’s warmth.
Sea Breeze and Local Climate
The Caspian brings steady breezes in spring. Locals call them the khazri (cold northern wind) and gilavar (warm southern wind), and they really influence how each day feels.
In March and April, the khazri can cool things down by a few degrees, keeping afternoons cooler than places farther inland.
By May, the gilavar shows up more, bringing warmer air that hints at summer.
These winds keep Baku’s climate more stable than other parts of Azerbaijan. You won’t see wild temperature swings like you might inland.
The breezes also help lower humidity, so outdoor activities feel more comfortable.
Wind strength changes day to day, but moderate gusts are common, especially by the sea. If you’re packing, throw in a light jacket—even on warmer days, the sea air can surprise you.
Spring Sea Temperatures
The Caspian warms up slowly after winter. Water temperatures hover near 7–8 °C (44–46 °F) in March.
By April, they get up to 10 °C (50 °F), and in May, they reach 15–16 °C (59–61 °F).
These cool waters help keep the coastal air mild. Even when May afternoons reach 18–21 °C (64–70 °F), evenings can feel cooler thanks to the sea.
Nights stay breezy and refreshing, especially along the Boulevard or in the Old City.
Most people don’t swim until late May, when the water finally loses its chill. For travelers, spring is better for walking tours, sightseeing, and enjoying Baku’s outdoor cafés than for swimming.
The sea’s slow warming is a big reason why spring in Baku feels so steady and drawn out. It balances cool mornings with warm afternoons, making the weather more predictable for outdoor plans.

Clouds tend to disappear fast as spring goes on. March brings plenty of cloudy skies, but by late May, you’ll notice mostly clear or just partly cloudy days.
Rain doesn’t stick around for long either. Early spring gets about 0.7 inches of rain, but this drops to roughly 0.3 inches by the end of the season.
Wind shapes the weather here, no doubt about it. In March, the average wind speed sits at about 12 mph. By May, it drops below 10 mph.
Along the coast, gusts can still surprise you. Daylight stretches out quickly in spring, and by late May, you get nearly 15 hours of sun.
