Weather and climate in Georgia: a region-by-region guide

Georgia has five climates, not one

Georgia is a small country with five genuinely distinct climates packed inside its borders. A traveller who lands in 32°C Tbilisi heat in August and flies to Mestia the next morning will need a fleece. A skier cutting turns at Gudauri in February can be swimming in Batumi two hours later, where early spring flowers are already appearing on the sheltered slopes.

This compression of climate zones is one of the country’s defining travel characteristics. Understanding which climate you are walking into matters more here than in most European destinations. The broad map:

• Eastern lowlands (Tbilisi, Kakheti): continental, hot summers, cold winters, moderate rainfall
• Western lowlands (Imereti, Samegrelo, Kutaisi): humid subtropical, warm and wet
• Black Sea coast (Batumi, Adjara): subtropical, mild winters, warm summers, very wet
• Lesser Caucasus (Borjomi, Bakuriani, Javakheti): mild mountain, cool summers, heavy snow
• Greater Caucasus (Svaneti, Kazbegi, Tusheti, Gudauri): alpine, short summers, severe winters

For a month-by-month breakdown of what these mean for travel, see the best time to visit guide. This guide focuses on the climate itself.

Tbilisi and the eastern lowlands

Summer: hot and dry

Tbilisi sits in a sheltered basin that traps heat. Average July highs run 31–34°C, with peaks above 38°C in heatwave years. The air is dry — humidity rarely exceeds 50% — which makes the heat more bearable than a comparable temperature in, say, Istanbul or Rome, but the midday sun is genuinely strong. Locals retreat indoors from about 2pm to 5pm; restaurants come alive again after 7pm when the streets cool.

Rain in summer is uncommon but dramatic when it arrives — thunderstorms roll in off the Caucasus, dump 30mm in an hour, and leave the air washed and clear for a day or two.

Autumn: the best Tbilisi weather

September is arguably the best month to be in Tbilisi. Daytime temperatures settle at 22–28°C, evenings are warm enough for outdoor dining, and the light goes long and golden. October continues the pattern with 16–22°C days and cooler nights. By November, daytime highs are 8–14°C with more frequent rain.

Winter: cold, occasionally snowy

Tbilisi winters are cold but not severe. Average daytime highs in January run 4–8°C; night lows hover around freezing. Snow falls two to five times a winter, usually settling for a day or two before melting. The city is not equipped for heavy snow — when it does fall, traffic becomes chaotic.

Tbilisi winters are dry — the heavy Caucasus winter precipitation falls as snow on the mountains, not as rain on the capital.

Spring: variable and beautiful

March is transitional — warm days alternating with cold snaps, and occasional snow in the first half. April settles into mild days (15–22°C) with cool nights. May approaches summer warmth (22–28°C) but without the heat peaks. Spring rain is more common than autumn rain.

What to pack for Tbilisi

• Summer: light cotton, linen, a hat, sunscreen. One light layer for air-conditioned interiors.
• Autumn: layers. Light jacket for evenings from mid-September, heavier by November.
• Winter: warm coat, waterproof shoes, hat, gloves. Nothing extreme.
• Spring: layers and a light rain jacket.

Kakheti and the eastern wine country

Kakheti’s climate is similar to Tbilisi’s but slightly more continental — hotter summer highs in the open valleys of the Alazani plain, colder winter nights in exposed Sighnaghi, more reliable wildflower springs across the vineyards.

Summer daytime temperatures in Telavi and the Alazani valley can exceed 35°C in July and August. The grape ripening depends on this heat. Autumn (September and October, the rtveli harvest season) settles into 20–26°C days, dry and bright. Winters are cold (January averages 0–6°C during the day) but rarely severe. Snow falls occasionally on the Caucasus foothills that back the region, less often in the valleys themselves.

For wine tourism, the climate window runs roughly April through early November. Winter is quieter but cellars are still open and the light on the vineyards is extraordinary.

The Black Sea coast and Adjara

This is the outlier climate and the one that surprises visitors most.

Subtropical Batumi

Batumi sits in a genuinely subtropical zone. Palms, magnolias, citrus trees and tea plantations grow within sight of snowcapped Caucasus peaks. The combination is strange and lovely.

Summer temperatures in Batumi are moderate (25–30°C, rarely higher) thanks to the sea. Humidity, however, is high — 70–80% is normal, and the air has the thickness of a tropical coast. Sea temperatures reach 24–26°C in July and August and are comfortable for swimming from mid-June through early October.

Winter is mild by Georgian standards. January daytime averages run 7–11°C, night lows 3–6°C. Snow on the coast is rare.

The defining feature of the Adjara climate is rainfall. Batumi receives more than 2,500mm of rain per year — roughly three times London’s total — and this rain is distributed through every month. Even in peak summer, thunderstorms roll in off the sea with little warning. Pack a light waterproof layer regardless of season.

The Adjara mountains

Inland from the coast, Adjara’s mountains (around Machakhela, Mtirala National Park, Khulo) are wetter still — Mtirala’s name means “weeper”, a reference to its constant rainfall. These are temperate rainforests, beautiful in autumn colour, often shrouded in cloud.

Imereti, Samegrelo and the western lowlands

Kutaisi and the western lowlands share the Black Sea’s humid subtropical pattern but with less extreme rainfall. Summers are warm (26–31°C) and humid, winters mild (4–10°C), rainfall spread across the year with spring and autumn peaks.

The cave cities of Prometheus, Sataplia, Martvili and Okatse are comfortable visits from April through October. Summer rain is common but short-lived — a thunderstorm at 3pm often clears by 5pm, leaving a sparkling afternoon.

The Lesser Caucasus: Borjomi, Bakuriani, Javakheti

Borjomi

Borjomi sits in a forested river valley at 800 metres. Summers are pleasantly cool (22–27°C days), autumns are spectacular with the Borjomi Gorge’s famous colour, winters are snowy and cold (-5 to 3°C daytime highs in January). The local microclimate — forested, sheltered, cool — is why Russian aristocracy made Borjomi a spa town and why the mineral water carries the Borjomi name worldwide.

Bakuriani

Bakuriani, at 1,700 metres, is Georgia’s second ski resort after Gudauri. Winters are properly snowy (January averages -8 to -2°C), snow cover from December to April, and the summer (15–22°C) is a pleasant mountain retreat.

The Javakheti plateau

The Javakheti volcanic plateau, the highest inhabited region of Georgia at 2,000–2,200 metres, has a harsh microclimate: short summers, long bitter winters, strong winds. The ancient cave city of Vardzia sits in a more sheltered valley below the plateau but is still affected by the high-altitude pattern.

The Greater Caucasus: Svaneti, Kazbegi, Tusheti, Gudauri

The high mountains are where Georgia’s climate becomes serious.

Summer

June through early September is the usable window for high-altitude travel. Mestia, at 1,500 metres in Svaneti, has summer daytime highs of 20–26°C. Ushguli, at 2,200 metres, is cooler still (15–22°C). Kazbegi (Stepantsminda), at 1,740 metres, runs similar temperatures.

Afternoon thunderstorms are the constant feature of Greater Caucasus summers. Mornings are often clear; by 2pm clouds build; by 4pm storms can be severe. Experienced trekkers aim to be off exposed ridges by early afternoon. This is not a suggestion — it is a safety rule. See the best hikes guide for the specifics.

Autumn

September brings cooler days, clearer weather, and the most reliable trekking conditions of the year. By mid-October, first snow is possible at altitude and high trekking routes are closing. The Abano Pass to Tusheti typically closes in early October and reopens in early June.

Winter

Winter in the high Caucasus is severe. Snow accumulates from November through April; temperatures regularly drop below -20°C in Mestia and Kazbegi. Roads into Svaneti remain open (the main highway is ploughed) but Tusheti is completely cut off — Omalo is accessible only by helicopter or long ski tour.

Gudauri is Georgia’s main ski resort and sits at 2,200 metres — the snow season runs reliably from December through March, sometimes into April. Stepantsminda and Kazbegi in winter are cold but atmospheric, with the Gergeti Trinity Church set against snowbound peaks.

Spring

Spring comes late to the high mountains. Mestia does not properly shed snow until April or May; Tusheti snow-melts are in June. Wildflowers appear on Svaneti’s alpine meadows from late May through early July, a short and spectacular window.

Rainfall patterns at a glance

Region	Driest months	Wettest months	Annual rainfall
Tbilisi	July–September	April–June	550mm
Kakheti	July–September	April–May	650mm
Batumi	Spring/late summer	September–December	2,500mm+
Kutaisi	Summer	Spring/autumn	1,400mm
Borjomi	Summer	Spring	800mm
Svaneti (Mestia)	Winter (as snow)	Summer storms	1,000mm
Kazbegi	Late winter	May–July	900mm

Altitude and temperature: a rough conversion

For every 1,000 metres you climb, temperature drops roughly 6–7°C. This means that a 30°C Tbilisi afternoon corresponds to about 17°C in Mestia and around 12°C on the high meadows above Ushguli. Pack accordingly for mountain trips.

What to pack by season

Summer (June–August)

• Lowlands and Tbilisi: Light, breathable clothing. Sunscreen and a hat are not optional.
• Mountains: Layers. Base layer, fleece or light down, waterproof shell. Proper hiking boots if you plan to walk.
• Black Sea: Swimwear plus a light waterproof layer — the sudden rainstorms are real.
• Everywhere: A reusable water bottle. Georgian tap water is safe in cities and mountain springs are abundant.

Autumn (September–November)

• Early autumn: Summer wardrobe plus a light jacket for evenings.
• Late autumn: Proper jacket, waterproof shoes, layers for temperature swings.
• Mountains: Winter kit starting from mid-October.

Winter (December–February)

• Lowlands and Tbilisi: Warm coat, hat, gloves, waterproof boots. Nothing extreme — this is not Siberia.
• Ski resorts and mountains: Proper winter gear. Ski thermals, insulated jacket, waterproof trousers if you plan to walk in snow.
• Black Sea: Autumn wardrobe suffices — Batumi winters are mild.

Spring (March–May)

• Layers, layers, layers: Mornings cold, afternoons warm, evenings cold again.
• Light rain jacket: Useful across all of Georgia in spring.
• Modest church-appropriate clothing: Easter falls in April or May and churches get busy — see Georgian etiquette for dress expectations.

Heat stress, altitude and weather hazards

Tbilisi summer heat

Heatwaves above 38°C happen every summer. Hydrate, avoid midday sun, and use air-conditioned cafes as base camp. The heat is usually broken after 4–5 days by a thunderstorm.

Mountain thunderstorms

Build in afternoon, strike with lightning on exposed terrain. If you are trekking, start early and be off ridges by early afternoon. See the safety guide for full mountain hazard coverage.

Black Sea humidity

Batumi’s humidity can make the mid-20s feel like the mid-30s. The saving grace is the sea breeze — most beach afternoons are comfortable because of it.

Winter cold in the mountains

Proper cold-weather gear is not optional in Svaneti or Kazbegi in January. -15°C nights are routine and the wind chill extends further. If you are ski touring or backcountry, full alpine kit is required.
