Fall in Tbilisi brings a steady shift from warm late-summer days to crisp, cool evenings. Expect average daytime highs to drop from the low 80s °F in early September to the upper 40s °F by late November, making autumn one of the most comfortable times to explore the city.
Nights cool down quickly, but the season rarely feels harsh compared to winter.
You’ll see the skies shift too. Early fall usually stays bright and clear, but cloud cover creeps in as the months go by.
Rainfall stays moderate and gradually decreases, so you probably won’t deal with long stretches of wet weather.
With shorter daylight hours and calmer winds, the city settles into a slower rhythm that feels just right with its historic streets and hillside views. If you want to enjoy pleasant weather and fewer crowds, autumn offers a practical and inviting window to experience Tbilisi.
Overview of Tbilisi’s Fall Climate
Tbilisi’s fall climate reflects its spot between the Caucasus Mountains and the Black Sea, giving it a blend of continental and subtropical influences. You get cooler days, shorter daylight, and less rain as the season moves on.
Weather can shift quickly from warm early autumn to chilly late November.
Geographic Influences on Weather
Tbilisi sits in eastern Georgia, tucked in the Kura River valley at about 1,600 feet (490 meters) above sea level. This valley location shields you from some of the harsher winds blowing down from the Greater Caucasus Mountains to the north.
The Caucasus range blocks much of the cold Arctic air, and the Lesser Caucasus to the south adds another barrier. These mountains act like a buffer, keeping fall temperatures milder than what you’d get farther north.
The Black Sea, roughly 200 kilometers west, also plays a part. Moist air from the sea drifts inland but loses steam by the time it gets to Tbilisi, so the city feels less humid and gets less rain than western Georgia.
This mix of elevation, valley geography, and distance from the sea gives you a climate that sits somewhere between maritime and continental.
Seasonal Climate Patterns
During fall, daily high temperatures in Tbilisi drop from around 83°F (28°C) in early September to about 49°F (9°C) by late November. Nighttime lows fall from the low 60s°F (16–17°C) to near freezing.
Rainfall drops off as the season goes on. Early autumn brings about 0.8 inches (20 mm) of rain in a 31‑day period, but by late November it’s closer to 0.4 inches (10 mm). You’ll probably get more crisp, dry days as fall winds down.
Cloud cover thickens a lot. Clear skies are common in early September, but by November, overcast days show up nearly half the time. Daylight shrinks fast, from over 13 hours in early September to just above 9 hours by late November.
Humidity drops too, and by late autumn, muggy days are rare. Winds stay light, averaging 4–5 miles per hour, and usually come from the east.
Comparison to Other Georgian Regions
If you head west toward the Black Sea coast, places like Batumi deal with much wetter fall weather. Rainfall there is several times higher than in Tbilisi, and the clouds just stick around.
The maritime influence keeps things milder, so nights rarely get close to freezing.
In the Greater Caucasus, places like Kazbegi cool off much faster. Frost and snow can show up by October, while Tbilisi usually stays frost‑free until late November.
Southern areas near the Lesser Caucasus, such as Akhaltsikhe, tend to be cooler and drier. These spots don’t get the Black Sea’s moderating effect, so temperatures can drop sharply at night.
Tbilisi lands in the middle: less rain than the west, warmer than the mountains, and more stable than the southern highlands. It’s honestly one of the more balanced fall climates in Georgia.
Typical Temperatures in Autumn
In Tbilisi, fall brings a steady cooling trend with noticeable changes from September to November. Early in the season, you’ll get warm days, but by late autumn, temperatures often dip close to winter levels.
The shift brings bigger differences between daytime highs and nighttime lows.
Average Highs and Lows by Month
In September, average highs reach about 83°F (28°C), while lows hover near 63°F (17°C). The month still feels like late summer, with plenty of warm afternoons.
By October, highs drop to around 67°F (19°C) and lows settle closer to 48°F (9°C). The air feels cooler, especially after sundown, and you’ll see more light jackets out and about.
In November, highs average only 49°F (9°C), while lows fall near 34°F (1°C). Nights can get close to freezing, hinting that winter’s on the way.
| Month | Avg High °F (°C) | Avg Low °F (°C) |
|---|---|---|
| September | 83 (28) | 63 (17) |
| October | 67 (19) | 48 (9) |
| November | 49 (9) | 34 (1) |
These changes make autumn one of the most varied seasons in Tbilisi’s climate.
Temperature Variability and Extremes
You’ll notice that fall temperatures don’t really follow a strict pattern. Early September can still bring days above 85°F (29°C), while late November may dip below 32°F (0°C) at night.
Extremes happen, but not often. It’s rare for temperatures to go above 92°F (33°C) in September or drop below 27°F (-3°C) in November. Still, these outliers show how quickly the region can flip between warm and cold.
Tbilisi’s inland spot and the hills around it add to the variability. Cool air from the Caucasus Mountains can sweep in and make evenings feel much colder than you’d expect.
Daytime Versus Nighttime Conditions
During fall, the gap between day and night temperatures widens. In September, nights stay mild, but by November, the difference between afternoon highs and overnight lows often tops 15–20°F (8–11°C).
Daytime in early autumn usually feels great for walking or eating outside. As the season moves on, you’ll want warmer clothes for mornings and evenings, even if afternoons stay nice.
By late autumn, you might wake up to crisp, chilly mornings and get just a short, cool afternoon. Layering clothes really is the way to go if you’re spending time outdoors in Tbilisi during this season.
Rainfall and Humidity Trends
During fall in Tbilisi, you’ll notice steady changes in both rainfall and air moisture. Showers become more common than in summer, and humidity rises as cooler air holds water better.
These shifts shape how comfortable the city feels and can change how you plan your time outside.
Monthly Precipitation Levels
Rainfall in Tbilisi increases gradually from September to November. September averages about 40–50 mm of rain, spread across 6–7 days. By October, totals rise closer to 60–70 mm, with more frequent showers.
November often brings the highest fall rainfall, averaging 70–80 mm across 9–10 days.
The city’s location between the Greater Caucasus Mountains and the Kura River valley really matters here. Moist air from the Black Sea can move inland and meet cooler air, leading to heavier showers in autumn.
Rain usually falls in short bursts instead of long downpours, though November can bring longer wet spells.
Compared to winter, fall rainfall is moderate, but it’s definitely higher than in the dry summer months. Expect more cloudy days and sometimes fog, especially as November winds down.
Humidity Fluctuations
Humidity in Tbilisi is moderate for much of the year, but fall brings a clear upward trend. In September, average relative humidity sits around 60%, which feels pretty comfortable.
By October, it climbs closer to 65–70%, and in November it often reaches 75% or higher.
This bump happens as temperatures drop and the air holds more moisture. Unlike the coastal areas near the Black Sea, Tbilisi doesn’t get constant dampness, but you’ll notice the change.
Early mornings and evenings often feel more humid, especially when fog settles in the valleys.
The higher humidity can make cool days feel chillier than the numbers suggest. At the same time, it cuts down on the dryness you get in summer, when humidity might dip below 50%.
Impact on Outdoor Activities
Rising rainfall and humidity definitely affect how you spend time outside in Tbilisi during fall. September still gives you plenty of dry, pleasant days for walking the Old Town or checking out nearby vineyards. Light rain gear is usually enough.
By October, you’ll want to be ready for more showers. Carrying an umbrella or a waterproof jacket just makes sense, especially if you’re planning day trips into the hills or along the river.
In November, wetter weather and higher humidity can make outdoor sightseeing a bit unpredictable. Hiking trails might get muddy, and fog sometimes limits views in higher spots.
Still, most cultural sites and city attractions are easy to enjoy if you plan around the wetter spells.
Sunshine, Wind, and Air Quality
During fall in Tbilisi, daylight hours shrink, winds shift as the season changes, and air quality can vary with the weather and city activity. Knowing what to expect helps you plan your outdoor time and stay comfortable during your trip.
Average Sunshine Hours
In the fall months, you’ll see a steady drop in daily sunshine. September gives you about 6–7 hours of sun per day, so there’s still plenty of daylight for sightseeing.
By November, this drops to about 3–4 hours daily, making days feel shorter and a bit cooler.
Less sunshine also means it doesn’t warm up as much outside. Even if early fall temperatures are mild, shorter daylight means less time for the ground and air to heat up.
Evenings cool down quickly, especially in October and November.
If you love photography or outdoor activities, September gives you the best light. Later in the season, it’s smart to plan outings around midday when the sun is strongest.
Wind Patterns in Fall
Tbilisi sits in a valley along the Kura River, surrounded by the Caucasus foothills, so the geography shapes its wind patterns. In fall, winds generally stay light to moderate, averaging 2–3 m/s (4–7 mph).
September often feels calm, but by October and November, breezes pick up as cooler air moves through. These winds can make evenings feel colder than the thermometer says.
You won’t usually get strong winds in the city, though higher elevations just outside Tbilisi can get gusty. For travelers, this means walking tours and outdoor dining are rarely disrupted, but you’ll want a light jacket when the wind picks up.
Air Quality Considerations
Air quality in Tbilisi during fall is usually moderate, but it can change. Cooler weather knocks down summer dust, but urban traffic and heating emissions tend to increase in October and November. On still days with little wind, pollutants can linger in the valley.
You might notice clearer air in September when things are drier and breezier. Later in the season, haze is more likely, especially in the mornings. Sensitive groups, like people with asthma, should check conditions before spending hours outside.
If you’re planning to hike in the surrounding Caucasus foothills, air quality is usually better up there. Fall is honestly a good time to mix city exploring with trips into the countryside.
Regional Weather Comparisons
Tbilisi’s fall climate comes from its inland valley location, while nearby regions see very different weather thanks to the Black Sea and the Caucasus Mountains. You’ll notice sharper contrasts in temperature, rainfall, and cloud cover when you compare the capital with Georgia’s coastal and mountain areas.
Tbilisi Versus Svaneti in Fall
Svaneti rises high in the Caucasus Mountains, with many towns perched above 1,500 meters. Tbilisi, by comparison, sits in a valley at about 500 meters, so the mountain air up in Svaneti feels much colder in fall.
Daily highs in Svaneti usually hover around 40–50°F (4–10°C). Meanwhile, Tbilisi still enjoys 60–70°F (15–21°C) through September and early October.
Snow shows up much earlier in Svaneti. By late October, you might already spot snow-covered passes, while Tbilisi stays snow-free until winter finally rolls in.
Mountain travel in Svaneti gets tricky in fall because of this early snow.
Rainfall patterns look pretty different too. Tbilisi gets less than an inch of rain per month by late fall. Svaneti, though, sees much heavier precipitation as moist Black Sea air climbs over the mountains.
So, you’ll find frequent rain or snow showers in Svaneti, but Tbilisi stays mostly dry.
If you want crisp, accessible fall weather, Tbilisi makes travel a lot easier. But if you’re after alpine views and don’t mind colder, wetter days, Svaneti gives you a much harsher, but honestly, a strikingly beautiful climate.
Tbilisi Versus Batumi Coastal Climate
Batumi sits right on the Black Sea coast, so it gets a humid subtropical climate. In fall, Batumi turns much wetter than Tbilisi.
Average rainfall in Batumi often passes 200 mm per month. Tbilisi, on the other hand, rarely gets more than 20–30 mm. You’ll run into frequent showers and cloudy skies along the coast, while Tbilisi usually enjoys drier, clearer days.
Temperatures don’t match up either. Batumi’s coastal influence keeps nights mild, usually above 55°F (13°C) even in November.
Tbilisi cools off much faster, with lows heading toward 35°F (2°C) by late fall. Batumi feels damp but relatively warm, while Tbilisi comes across as cool and dry.
Humidity really stands out here. Batumi’s air stays heavy with moisture. Tbilisi in fall feels increasingly crisp and not so humid.
If you’re planning outdoor activities, this matters—a hike near the coast may feel muggy, but Tbilisi’s air is more comfortable.
The Black Sea smooths out Batumi’s climate, making it quite different from Tbilisi’s inland valley vibe. You’ll notice wetter, greener landscapes on the coast, and drier, more stable weather in the capital.
Travel Tips for Visiting Tbilisi in Autumn
Temperatures in Tbilisi slide steadily from warm September days to cool November nights, so you’ll want to prepare for a wide range of conditions.
Autumn brings colorful foliage, wine festivals, and fewer tourists. It’s honestly a comfortable, rewarding time to explore the city.
Best Clothing for Fall Weather
Early autumn in Tbilisi often feels a lot like late summer. Daytime highs in September land around 23°C (73°F), and nights dip to about 15°C (59°F). A light jacket or cardigan works well, and breathable clothes keep you happy in the afternoon sun.
By October, cooler air moves in. Daytime averages hit 16°C (61°F), nights drop to 10°C (50°F). You’ll want to pack warmer layers—think sweaters, a medium-weight jacket, and closed shoes. A scarf or light hat helps a lot during breezy evenings.
November brings the biggest change, with average highs near 10°C (50°F) and lows around 5°C (41°F). You’ll need a heavier coat, thicker layers, and waterproof shoes since rain shows up more often.
Gloves and a warm hat come in handy if you plan to stay out after sunset.
A solid packing list looks like this:
- Light shirts and trousers for early autumn
- Sweaters and a medium jacket for mid-season
- A heavier coat, scarf, gloves, and sturdy shoes for late autumn
Recommended Activities
September feels perfect for getting outside and exploring. You can wander through Old Tbilisi or grab a seat at a rooftop cafe, maybe even take a boat ride on the Kura River if you’re up for it. The weather stays warm, so parks like Mtatsminda Park and the Botanical Garden start to show off those early autumn colors.
In October, Kakheti comes alive with the wine harvest. It’s just a short trip from the city, and a lot of people join wine tours to check out the vineyards and try local wines. The Tbilisi Wine Festival draws crowds too.
Back in the city, museums and cultural events start to pop up everywhere in the fall. If you’re into that sort of thing, there’s plenty to see.
By November, the air turns cooler, and indoor spots start to sound more inviting. The sulfur baths in Abanotubani offer a warm escape, and cozy cafes dish out traditional Georgian food.
You can still get out for a scenic walk, but with the sun setting earlier, it’s smart to plan daytime activities.
