Tbilisi in Summer: Heat, Swimming and How to Plan the Days

Tbilisi is known for hot, dry summers: July and August afternoons average 33 C (91 F), and heat waves push the city to 38 to 40 C. Summer is also when the lakes open for swimming, the terraces stay full past midnight and the mountain roads are clear. Below is how the three summer months compare, how I'd plan a hot day, where to swim, and the trips out of town that make the heat easy.

How hot is Tbilisi in summer?

Hot, and dry with it. The city sits in a bowl of hills with no sea breeze, so the heat builds through the afternoon and the stone lanes of Old Tbilisi hold onto it well into the evening. The sky is mostly clear from late June to August, and rain, when it comes, is a short thunderstorm rather than a wet day.

Here is the summer at a glance, with September added because it still feels like summer for its first two weeks.

Those are averages. A heat wave in July or August can sit at 38 to 40 C (100 to 104 F) for several days, and the old town is built on steep hills, so a walk that takes 15 minutes in May feels twice as long at 3 pm in August.

June, July or August: which summer month to pick

The three summer months are very different trips. June is a city break with warm evenings, July and August are a city break that needs a plan, and August has a quirk of its own: the locals leave.

Tbilisi in June

June is my favorite summer month. Days sit around 18 to 28 C, the parks and hills are still green, and the outdoor season is in full swing with terraces open and concerts in the gardens. The first half of the month can bring short afternoon showers, which is the main reason it's not perfect, and the heat usually arrives in the last week.

Tbilisi in July

July is properly hot, at 21 to 33 C on average and higher in a heat wave. It's also one of the best months for culture: the Art-Gene folk festival takes over the open-air museum in late July, and in 2026 the Sukhishvili national ballet opened it. I'd do July as a split trip, 3 or 4 days in the city and 2 or 3 in the mountains.

Tbilisi in August

August is the hottest month and, oddly, the quietest one among locals. Many Tbilisians leave for the Black Sea at Batumi and Kobuleti, or for the mountains in Mestia and Racha, so the residential streets empty out while the old town fills with visitors. Late August gets a little cheaper as the season winds down, and 28 August is Mariamoba, a public holiday, when banks and offices close.

Summer is the peak for both crowds and room prices, while the best time to visit Tbilisi for a city-only trip is late April to June or September to October.

How to plan a hot day in Tbilisi

The rule I follow in July and August is simple: outside before 11:00 and after 17:00, inside or in the water in between. Tbilisi suits this rhythm, because the city eats late, the terraces fill after dark and almost everything stays open into the evening.

The walking part works best in the shaded lanes of Sololaki and Abanotubani, and the Leghvtakhevi waterfall gorge behind the baths stays shaded and cooler than the streets above it. Save the long, exposed climbs for the evening.

Where to swim in Tbilisi in summer

Tbilisi is landlocked, but it has a reservoir, two small lakes, a water park and a run of outdoor pools, and on a hot afternoon half the city is in one of them. Here's how they compare.

My pick for a first summer trip is Lisi Lake in the late afternoon. It's a short taxi ride from the center, the shore has a walking path and cafes, people swim off the pebbly beaches, and it costs nothing but the ride. The outdoor pools are the better choice when you want a lounger, clean water and a drink without leaving the city; most open from late May to early or mid September, with the water at about 24 to 27 C.

For a full beach day, the Tbilisi Sea is the big one: a long reservoir on the northeast edge of the city with free public beaches, the Tbilisi Sea Club on the shore and Gino Paradise next to it. If you'd rather swim laps, the swimming pools in Tbilisi include two indoor 50 m pools that stay open all year, from 20 GEL for 2 hours at the Olympic Complex.

Cool places to spend a hot afternoon

Not every hot afternoon needs a swimsuit. These are the places I'd go between noon and 17:00 when the sun makes the streets hard work.

• Turtle Lake. The old cable car from the top of Vake Park climbs about 5 minutes over the trees to a small forest lake, for 1 GEL on a Metromoney card, daily 10:00 to 22:00. It's a few degrees cooler up there, and Turtle Lake has a shore path, cafes, paddle boats and a little beach where swimming is allowed from June to September.

• Museums. Thick walls and quiet halls make the best museums in Tbilisi a natural midday stop, though the Georgian National Museum, for one, closes on Mondays.

• The National Botanical Garden. Behind the fortress, a gorge of shade trees, a waterfall and paths along a stream, for 4 GEL. The botanical garden is the greenest hour you can spend in the old town.
• A long lunch in a courtyard. Tbilisi's courtyard restaurants and vine-covered terraces were built for this, and a slow lunch with a cold glass of white wine counts as sightseeing in August.

• The sulfur baths, late. A hot bath sounds wrong in July, but a private room booked for 21:00 or later is a different thing. The sulfur baths in Abanotubani stay open late, private rooms start at about 100 GEL, and you walk out into the cooler night air.

Ice cream and lemonade on a hot day

Two things get me through a Tbilisi August: a scoop of ice cream at 4 pm and a glass of Lagidze water, the fountain lemonade Tbilisi has poured since the 19th century. A single scoop of the best ice cream in Tbilisi costs about 4.50 to 5.40 GEL. These are the three stops I'd plan a walk around.

The Cone Culture

My first stop for ice cream in Tbilisi. It's a small shop at 5 Taras Shevchenko Street that makes everything in small batches, with flavors like feijoa, persimmon and vanilla with ajika, the Georgian chili paste, next to a very good salted caramel. The cones are baked in house, and the cinnamon one is why I order a cone instead of a cup. There's a second branch in Bazari Orbeliani, the restored market hall.

Luca Polare

The Georgian chain with the polar bear logo, at about 20 branches, so there's one near wherever you stay. The quality holds steady from branch to branch, the counter rotates through dozens of flavors, and the one to try is the Kindzmarauli wine ice cream, made with the semi-sweet red from Kakheti. The fruit sorbets are dairy-free, and the branches serve coffee and pastries too, which makes them an easy cafe stop on a hot afternoon.

Lagidze Water, Vake

The Lagidze cafe at 32 Zakaria Paliashvili Street in leafy Vake mixes the syrups with soda in front of you, from 10:00 to 22:00. Tarragon is the green one and the one to order first; chocolate and cream is the local favorite. Georgian lemonade from the fountain tastes nothing like the bottled kind, and the counter also sells hot khachapuri if the glass turns into lunch. I'd pair it with an evening walk in Vake Park.

Summer evenings in Tbilisi

Evenings are the best part of a Tbilisi summer. The heat breaks around 19:00, families come out to the parks, and the terraces stay busy until well after midnight. These are my three favorite ways to spend one.

Point Terrasse

For a sunset drink, this hotel rooftop at 15 Anton Catholicos Street in the Old Town is my first pick of the rooftop bars in Tbilisi, and the bar is open to non-guests. The view runs about 180 degrees, with Narikala on its ridge one way and Holy Trinity Cathedral across the river the other. It's calmer than most old town rooftops, with hotel-bar prices to match. Arrive before sunset and stay until the fortress lights come on.

Fabrika

The courtyard of a former Soviet sewing factory at 8 Egnate Ninoshvili Street, across the river in Chughureti, is where Tbilisi's younger crowd spends a summer night. It's a hostel with bars, cafes and street art wrapped around an open yard, beer runs 7 to 10 GEL and cocktails 14 to 20 GEL, there's no cover, and DJs play from Thursday. I'd go on a warm weekend after 21:00, when the Fabrika courtyard is at its loudest and the yard is full.

Mtatsminda Park

The amusement park on the mountain above the city is a summer evening tradition for Tbilisi families, with a Ferris wheel on the summit and the whole city at your feet. Ride the funicular up from Chonkadze Street, about 10 to 12 GEL for visitors on the park's own 2 GEL card, running from 10:00 to 23:00 or midnight. At Mtatsminda Park I go up for sunset and come down after dark, when the lights of the valley are the show.

Summer festivals and holidays in Tbilisi

Summer is festival season, with most of the big events in the open air. Dates change every year, so check each one's announcement before you book around it.

Art-Gene is the one I'd plan a trip around. It fills the Open Air Museum of Ethnography on the hill above Vake with folk ensembles from every region, and in 2026 day tickets cost 60 GEL early and 90 GEL later, or 145 to 190 GEL for all four days. Out in the regions, summer brings its own festivals in Georgia, from Lomisoba, an early June pilgrimage in the highlands, to Kvirikoba, the 28 July feast day in the Svaneti village of Kala.

Day trips to escape the summer heat

This is where summer beats every other season. The mountain roads are open, the high valleys are green, and the mountains run 10 to 15 C cooler than the city, so a hot week in Tbilisi with two days up high is one of the best trips you can do in Georgia.

Kazbegi on a day trip is the one I'd do first: a 10 to 12 hour day up the Military Highway, with a private driver at about 150 to 250 GEL per car. Leave by 08:00, because cloud builds over Kazbek by late morning even in summer, and pack a warm layer, since Gergeti sits at 2,170 m and the wind up there is cold.

A day in Borjomi is the gentler choice: a marshrutka from Didube for about 12 GEL, a walk through the forest to the sulfur pools, and mineral springs you can drink free in the park.

For the sea, the train from Tbilisi to Batumi takes about 5 hours and starts from 35 GEL in second class.

Summer is also the only window for Tusheti's mountain villages, where the one dirt road over the Abano Pass is reliably open from mid-June to the end of September.

What to wear and pack for Tbilisi in summer

Light clothes and good shoes, plus one layer for the mountains. Your packing list for Georgia in summer is short:

• Breathable clothes in cotton or linen. The heat is dry, so loose and light beats technical fabrics.
• A hat, sunglasses and sunscreen. There's little shade on the hills and the viewpoints.
• Comfortable shoes with grip. The old town is steep, and the worn paving stones get slippery.
• A scarf and a pair of long trousers or a long skirt for churches, which you'll pass all day.
• A warm layer for Kazbegi or Borjomi, where it's noticeably colder, especially at Gergeti and in the evenings.
• A refillable bottle. Tbilisi tap water is safe to drink, and 1.5 liters of bottled water costs 1 to 2 GEL if you prefer it.

Who should visit Tbilisi in summer

Summer suits some trips far better than others. Here's how I'd decide.

• Mountain lovers: go. June to September is the season for Kazbegi, Svaneti and Tusheti, and Tbilisi makes the perfect base at either end of the trip.
• City plus beach: go, and add Batumi. The Black Sea is warmest in July and August.
• Night owls: go. Rooftops, courtyards and parks are at their best on warm nights, and the city keeps late hours all summer.
• Festival goers: go in late July for Art-Gene, or in early summer for Tbilisi Open Air.
• Families with kids: June works well, with Gino Paradise, Turtle Lake and the Mtatsminda rides.

And when to wait:

• A city-only trip with lots of walking: pick late April to June or September to October instead. In August the hills are hard work.
• Anyone who struggles in heat: the heat waves are real, and Tbilisi in autumn gives you the same city at 12 to 21 C in October.
• Tight budgets: July and August are peak season for rooms; book early or come in the shoulder months.
