Summer in Yerevan greets you with long, dry days and loads of sunshine. You’ll find daytime temperatures climbing well above 30°C (86°F), especially in July and August.
Nights stay warm, but the lower humidity makes the heat a bit easier to handle than in other cities.
You rarely have to worry about rain in summer. Storms and showers almost never interrupt your plans.
Clear skies rule the season, and daylight can stretch nearly 15 hours at the peak of summer.
The combination of heat, light, and dry air shapes how the city moves in these months.
If you like being outdoors, summer gives you the best window to explore Yerevan’s landmarks and lively streets. Weather interruptions are few and far between.
Still, the sun is strong and the UV index is high, so it’s smart to pack sunscreen and plan for shade.
Typical Summer Temperatures in Yerevan
Hot afternoons, mild evenings, and little humidity define Yerevan’s summer. The hottest stretch usually lands in late July.
Early June and late August feel a bit cooler, but still bring plenty of warmth.
Nights stay comfortable, which makes the heat less intense overall.
Average Highs and Lows by Month
In June, you’ll see average highs around 81°F (27°C), and nights dip to about 56°F (13°C).
By July, the hottest month, highs jump to 88–92°F (31–33°C), with lows in the 62–68°F (17–20°C) range.
August stays hot, with highs near 86°F (30°C) and lows about 61°F (16°C).
These averages show a steady pattern—hot days, but not usually extreme, and nights that cool things off.
| Month | Avg High °F (°C) | Avg Low °F (°C) |
|---|---|---|
| June | 81 (27) | 56 (13) |
| July | 88–92 (31–33) | 62–68 (17–20) |
| August | 86 (30) | 61 (16) |
Humidity stays low, usually under 50%. The heat feels dry, not sticky like in coastal places.
Record Temperature Extremes
Averages stay reasonable, but sometimes the city bakes. Yerevan has seen summer highs above 99°F (37°C) on rare days.
These extreme days usually hit in late July, when the sun is relentless.
Nighttime records don’t get as wild. Even in early June, summer lows rarely drop below 50°F (10°C).
Yerevan’s elevation, over 3,200 feet (1,000 meters), keeps overnight heat from getting out of hand.
You probably won’t run into extremes, but it’s worth packing for strong sun and warm weather—especially if you’re here in July.
Daytime vs Nighttime Temperatures
The difference between day and night really stands out. Afternoons often hit the upper 80s°F (30–32°C).
At night, the temperature drops by 20–25°F (10–14°C).
This cooler air makes outdoor dinners and evening strolls surprisingly pleasant.
Early mornings can feel cool, around 60°F (15–16°C)—perfect for sightseeing before the heat kicks in.
By midday, the sun gets intense, and you’ll probably want a shady spot or an indoor break.
This daily swing brings balance: hot, dry days, then refreshing nights.
You can plan outdoor activities for mornings or evenings, and save indoor or shaded time for the hottest part of the day.
Rainfall and Precipitation Patterns
Yerevan’s summer brings low rainfall and dry air. Spring gets the most rain, but summer stands out for its arid weather and higher temps.
Monthly Rainfall Totals
Once summer arrives, rainfall drops sharply. June averages about 30–35 mm, making it the wettest summer month.
By July, you’ll see closer to 20 mm, and August is the driest, with only 14 mm on average.
This drop matches the region’s continental climate. Most moisture falls in spring.
Summer storms do happen, but they’re brief and scattered.
Long stretches of dry weather, especially in late July and August, are the norm.
| Month | Avg. Rainfall (mm) |
|---|---|
| June | 30–35 |
| July | ~20 |
| August | ~14 |
Yerevan ranks among the driest capitals in the region during summer.
Frequency of Rainy Days
Rainy days get fewer as summer goes on. In June, you might get rain on 7–8 days.
By July, that drops to 5–6 days, and in August, expect only 4–5 rainy days.
Most of these are quick afternoon showers or brief thunderstorms.
They almost never last long enough to ruin your plans.
Unlike spring, summer rain is usually isolated and doesn’t stick around.
You can count on long, dry stretches between showers.
That reliability makes summer a great time for outdoor plans and city travel.
Humidity Levels During Summer
Humidity stays low all summer in Yerevan. Relative humidity averages between 47% and 55%, with July and August being the driest.
These numbers are lower than what you’ll find in many European capitals.
Low rainfall and modest humidity combine for a dry heat, especially in August when highs often top 30°C.
Nights are cooler, but the air doesn’t get much damper.
This dryness keeps the heat from feeling oppressive, but you’ll want to watch out for sunburn and dehydration.
Hydration and shade matter more here than sticky humidity.
Sunshine and Daylight Hours
Yerevan’s summers bring long, bright days and tons of direct sun.
You’ll get clear skies and extended daylight that really set the tone for daily life and activities.
Average Daily Sunshine
Summers here are as sunny as it gets. July tops out with about 11–12 hours of direct sun per day and roughly 353 total sunshine hours.
June and August aren’t far behind, averaging 10–11 hours daily.
That puts Yerevan among Europe’s sunniest capitals.
For perspective, the city clocks about 2,621 hours of sun each year, more than London or even Rome.
With so much sun, shade, sunscreen, and water are a must if you’re out and about for long.
Clear skies mean you can count on good weather for sightseeing, hiking, or just hanging out at open-air cafés.
If you love bright, dry weather, July and August are your best bet.
Length of Daylight in Summer
Daylight in Yerevan stretches late into the evening in summer.
June brings the longest days, with about 15 hours of light—sunrise before 6:00 a.m. and sunset after 9:00 p.m.
July and August still offer 14–15 hours of daylight, so you’ve got plenty of time for outdoor fun.
Long evenings mean you don’t have to rush your plans.
Locals often gather in parks or stroll around Republic Square once the day cools off.
Compared to winter’s short days (sometimes less than 9 hours), the summer difference is huge.
You’ll notice how the extra daylight and strong sun make the season feel active and open.
Wind and Air Quality in Summer
Yerevan’s summer brings light to moderate winds and mostly dry air.
These conditions affect both how comfortable it feels outside and the air you breathe.
Prevailing Wind Directions
Summer winds in Yerevan are usually light, around 3–7 mph.
June tends to feel calmer, but July sometimes brings slightly stronger gusts.
Most winds come from the northwest and west, shaped by the city’s spot in the Ararat Valley.
Mountains surround the valley, so air doesn’t always circulate well.
Some days, especially in the evening, you might notice the air feels still.
Don’t expect much relief from the heat.
Unlike coastal areas, Yerevan’s winds are dry, not cool or refreshing.
If you’re planning to be outside, early mornings and late evenings usually feel best, when light winds and cooler temps combine.
Air Quality Conditions
Summer air quality in Yerevan often suffers from heat, traffic, and weak winds.
On hot, still days, pollutants can hang around, especially downtown where traffic is heavy.
Dust is another thing you’ll notice.
Dry weather and little rain in July and August let fine particles float in the air, especially when the wind dies down.
Even with these issues, many days still bring clear skies and good visibility.
If you’re sensitive to pollution, you’ll probably feel better in rural areas or at higher elevations near the city.
Plan your outdoor activities for the morning, when air quality tends to be best.
How Yerevan’s Summer Weather Compares Regionally
Yerevan’s summers are some of the hottest and driest in the South Caucasus.
The city’s spot in the Ararat Valley, about 1,000 meters up, means it’s warmer and sunnier than many nearby places, with long periods of clear skies and barely any rain.
Comparison With Other Armenian Cities
When you stack Yerevan against Gyumri or Vanadzor, the differences are obvious.
Both cities sit higher up, so their summers are several degrees cooler.
For example, Yerevan often hits 90–92°F (32–33°C) in July, but Gyumri averages closer to 80°F (27°C).
Rainfall varies too.
Yerevan’s dry summers are a sharp contrast to Vanadzor, which gets more afternoon showers thanks to its forests and mountain valleys.
That makes Vanadzor feel less dry, even when it’s warm.
Resort towns like Dilijan?
Expect cooler, damper weather.
Thick forests and higher elevation keep highs near 77°F (25°C)—a big drop from Yerevan.
That’s why so many locals escape north for cooler air during peak summer.
Comparison With Neighboring Countries
Yerevan beats Tbilisi, Georgia, for heat and dryness.
Tbilisi’s summer highs usually hover around 86°F (30°C), with more humidity and the odd storm.
Baku, Azerbaijan, gets even hotter, but its spot on the Caspian Sea means the humidity is higher, so the heat feels heavier than Yerevan’s dry warmth.
Eastern Turkey’s highland cities, like Kars or Erzurum, stay cooler in summer.
Highs there often sit in the mid-70s °F (mid-20s °C), much lower than Yerevan.
So, regionally, Yerevan stands out as one of the hottest spots in the Caucasus interior, shaped by its valley setting and dry, sunny summer weather.
Tips for Experiencing Summer in Yerevan
Try planning your days around the heat. Afternoon highs usually climb to 31–34°C (88–93°F), so it really feels better to get out early in the morning or wait until later in the evening.
During midday, most people duck into shaded cafés, museums, or find something indoors to do.
Don’t forget to carry water with you. The air stays pretty dry, and even though humidity barely registers, dehydration can sneak up on you fast.
Lightweight, breathable clothes and sunscreen go a long way if you want to stay comfortable outside.
You can expect mostly clear skies. By late summer, cloud cover drops to about 4%, so the sun feels relentless most days.
Sunglasses and a hat really help, especially when you’re wandering around big open spots like Republic Square or Victory Park.
Rain doesn’t show up much, but you might catch a quick shower in early summer. If you’re coming in June, it’s smart to toss a light jacket or umbrella in your bag since it rains a bit more than in August.
Here’s a quick reference for planning:
| Factor | What to Expect in Summer |
|---|---|
| Daytime Highs | 27–34°C (81–93°F) |
| Night Lows | 13–20°C (55–68°F) |
| Rainfall | Decreases from ~24 mm in June to ~8 mm in August |
| Humidity | Very low, rarely muggy |
| Sunshine Hours | Long days, up to 15 hrs in June |
Evenings cool off nicely, dropping into the mid-teens Celsius (50s–60s°F). Outdoor dining and evening strolls feel especially inviting.
If you’re thinking about hiking or heading out to nearby sites, start early. You’ll get the light breeze, clear skies, and honestly, it’s just more enjoyable before the afternoon heat kicks in.
