Tbilisi has a climate that catches a lot of visitors off guard. People arrive in July expecting a pleasant Caucasus mountain city and instead walk into 35°C heat rising off the pavement in the Old Town. Others show up in January in a light jacket and spend the trip shivering. Getting the Tbilisi weather right before you book is the difference between a comfortable trip and a slightly miserable one.
This guide breaks the year down month by month, with realistic average high and low temperatures in °C, what the rain and crowds are usually like, and what each month is actually good for. I have also added practical packing notes per season and a word on the famous Tbilisi wind, which surprises almost everyone. Use it to pick your dates and pack sensibly.
Tbilisi’s climate at a glance
Tbilisi sits in a river valley at around 400–500 metres above sea level, hemmed in by hills. Its climate is humid subtropical leaning towards continental: hot, dry summers and mild-to-cold winters, with a clear wet season in spring. The valley setting matters — it traps summer heat and channels the wind, which is why the same day can feel different depending on which side of the Mtkvari River you are standing on.
- Hottest months: July and August, with highs often 33–37°C.
- Coldest months: January and February, highs around 6–9°C, nights near or below freezing.
- Wettest season: spring, especially April, May and early June.
- Best all-round months: May, June, September and early October.
- Snow: possible December to February, but rarely deep or long-lasting in the city.
Tbilisi weather month by month
Here is the full year, month by month. Temperatures are typical averages — individual days can swing well above or below these figures, especially in the shoulder seasons.
January
Average high 7°C, low 0°C. The coldest month, with grey skies, occasional light snow and the odd crisp sunny day. Crowds are thin and prices are at their lowest. Good for a quiet, cheap city break, the sulfur baths, and museums. Bring a proper coat; pavements can be icy in the Old Town’s steep lanes.
February
Average high 9°C, low 1°C. Still winter, but you start to feel it easing towards the end of the month. Snow is possible but usually melts fast. Quiet and affordable, with the same indoor-focused appeal as January. A solid choice if you want to pair Tbilisi with a nearby ski trip to Gudauri.
March
Average high 12°C, low 3°C. Early spring is changeable — warm afternoons, cold mornings, and the first proper rain. Trees begin to bud and the city feels like it is waking up. Crowds are still light. Layers are essential, as is a compact umbrella.
April
Average high 18°C, low 7°C. Spring properly arrives, and it is lovely — green hills, blossom, and comfortable walking weather. It is also one of the wettest months, so expect showers. Crowds start to build around the Orthodox Easter period. Great for the botanical garden and long walks along the river.
May
Average high 23°C, low 12°C. One of the best months to visit. Warm but not hot, everything is green, and terrace season is in full swing. There is still a fair amount of rain, often as short afternoon thunderstorms, but it clears quickly. Crowds are moderate. Ideal for both sightseeing and day trips.
June
Average high 28°C, low 16°C. Early summer is warm and mostly sunny, with the last of the spring rain tapering off. Long evenings are perfect for wine bars and rooftop terraces. Crowds grow through the month as the peak season begins. Bring sunscreen and a light layer for the evenings.
July
Average high 33°C, low 20°C. Peak heat. Afternoons regularly hit 33–37°C and the valley holds the warmth, so it can feel stifling in the middle of the day. It is dry, though, so mornings and evenings are pleasant. This is high season, so book accommodation early. Plan sightseeing for before 11am and after 6pm, and hide indoors or head to the mountains at midday.
August
Average high 33°C, low 20°C. Much like July — hot, dry and busy. Many locals leave the city for the mountains or the Black Sea coast, so some smaller places close for a couple of weeks. Great for early-morning walks and late dinners, less great for midday exploring. This is prime season for escaping to cooler day trips like Kazbegi.
September
Average high 28°C, low 15°C. Arguably the single best month. The intense heat breaks, the days stay warm and sunny, and it coincides with the grape harvest (rtveli) in the wine regions. Crowds thin out slightly after the summer peak. Perfect for city walking, wine country and day trips alike.
October
Average high 20°C, low 9°C. Autumn is beautiful, with golden hills and comfortable temperatures early in the month. Rain returns gradually and the second half cools noticeably. Tbilisoba, the city’s founding festival, usually falls in October and fills the Old Town with food, wine and music. A wonderful, less-crowded time to visit.
November
Average high 12°C, low 4°C. Late autumn turns grey and damp, with bare trees and shorter days. It is low season, so it is quiet and cheap. A good choice if you like a moody, atmospheric city and plan to spend time in cafés, wine bars and baths. Bring a warm coat and waterproof shoes.
December
Average high 8°C, low 1°C. Proper winter, with cold days, occasional snow and festive lights going up around Rustaveli Avenue. Georgian New Year celebrations run into early January and give the city a warm, festive feel. Quiet apart from the holiday period. Ideal for the sulfur baths and cosy Georgian restaurants.
The hottest months: July and August
If you can only travel in high summer, go in with a plan. The heat itself is dry rather than sticky, which makes it more bearable than a humid coastal city, but the valley traps it and radiates it back off stone and asphalt. Midday temperatures of 33–37°C are normal, and the Old Town’s exposed lanes and metal-railed viewpoints get genuinely uncomfortable between noon and 4pm.
The trick is to structure your day like locals do: be out early, retreat somewhere shaded in the afternoon, then come alive again in the evening. Carry water everywhere, and keep a hat and high-factor sunscreen on hand. This is also the perfect time to swap a hot city afternoon for a cooler mountain day trip, as the temperature drops noticeably as you gain altitude towards Kazbegi or Gudauri.
The wettest season: spring rain
Spring is when Tbilisi gets most of its rain, with April, May and early June the wettest stretch of the year. It rarely rains all day, though. The typical pattern is a warm, bright morning followed by a short, dramatic afternoon thunderstorm that clears within an hour, leaving the air fresh and the hills vividly green.
For visitors this is manageable rather than trip-ruining. Pack a compact umbrella or a light rain jacket, wear shoes that can handle wet cobbles, and keep your plans flexible enough to duck into a café or gallery when the sky opens. The reward is the lushest, greenest version of the city and its surroundings.
Winter and snow in Tbilisi
Tbilisi winters are cold but not brutal. Daytime highs sit around 6–9°C from December to February, with nights hovering near or just below freezing. Snow does fall, but the city is low and relatively mild by Caucasus standards, so it usually arrives in thin flurries that melt within a day or two rather than settling into deep drifts. A properly white, snow-blanketed Tbilisi happens most winters but does not last long.
Winter has real charm: steaming sulfur baths make far more sense in the cold, Georgian comfort food and qvevri wine hit differently, and the low-season prices are a genuine draw. Just pack for it — a warm coat, gloves, a hat and grippy, waterproof shoes for the steep, occasionally icy Old Town lanes. If you fancy snow, the ski resort of Gudauri is only a couple of hours away.
The best months to visit
If comfort is your priority, the shoulder seasons win easily. Late spring (May and early June) gives you warm days, green landscapes and manageable crowds, with only the occasional shower to plan around. Early autumn (September and early October) is arguably even better: the summer heat has broken, the light turns golden, the wine harvest is in full swing, and the peak-season crowds have started to fade.
Summer suits those who don’t mind heat and want long, lively evenings and full festival energy, while winter rewards travellers chasing low prices, quiet streets and a cosy, atmospheric city. For a full breakdown of dates, festivals and trade-offs, see our dedicated guide on the best time to visit Tbilisi, and keep an eye on the seasonal events calendar when picking your window.
What to pack by season
Whatever the month, comfortable shoes with grip are non-negotiable — Tbilisi is built on hills and its Old Town cobbles are uneven. Beyond that, pack for the season:
- Spring (Mar–May): layers, a light waterproof jacket, a compact umbrella and a warmer top for cool evenings.
- Summer (Jun–Aug): light, breathable clothing, a sun hat, high-factor sunscreen, sunglasses and a reusable water bottle.
- Autumn (Sep–Nov): layers that span warm early-autumn days and cold, damp Novembers, plus a rain jacket.
- Winter (Dec–Feb): a proper warm coat, gloves, a hat, thermal layers and waterproof, grippy shoes for icy lanes.
The Tbilisi wind and local microclimates
One thing the temperature charts never tell you is the wind. Tbilisi’s valley acts like a funnel, and on certain days a dry, gusty wind sweeps down through the city. Locals half-jokingly blame it for headaches and bad moods. It can pick up in any season, and it noticeably changes how the temperature feels — a 30°C afternoon becomes pleasant with a breeze, while a cold, windy winter day feels far harsher than the number suggests.
The city also has real microclimates. The higher districts and the slopes around Mtatsminda are usually a degree or two cooler and breezier than the valley floor, while the enclosed Old Town lanes can feel like an oven in summer. Don’t be surprised if the weather feels different across a short walk — factor in the wind, and always carry one extra layer regardless of the forecast.
Frequently asked questions
What is the hottest month in Tbilisi?
July and August are the hottest, with average highs around 33°C and afternoon peaks that often reach 35–37°C. The heat is dry rather than humid, but the valley traps it, so midday can feel intense. Plan your sightseeing for the cooler mornings and evenings.
Does it snow in Tbilisi?
Yes, but usually only lightly. Snow falls most winters between December and February, but because the city is relatively low and mild, it tends to melt within a day or two rather than settling deeply. For reliable snow and skiing, head to Gudauri a couple of hours north.
What is the rainiest time of year in Tbilisi?
Spring is the wettest season, with April, May and early June seeing the most rain. It rarely rains all day, though — the usual pattern is a bright morning followed by a short, sharp afternoon thunderstorm that clears quickly. A compact umbrella is all you really need.
When is the best weather in Tbilisi?
Late spring (May to early June) and early autumn (September to early October) offer the most comfortable weather — warm, sunny days without the extreme summer heat, and fewer crowds. September is a particular favourite thanks to the mild temperatures and the grape harvest in the wine regions.
