Georgia weather by month: Tbilisi, Batumi, Kazbegi, Svaneti and Kakheti temperatures, rain and snow

Tbilisi, Batumi, Kazbegi, Svaneti and Kakheti sit close together on the map but behave like five different countries in the weather charts. Tbilisi and Kakheti share a dry, continental climate with hot summers and crisp winters; Batumi and the rest of the Black Sea coast are humid subtropical, wet in every season and warmest for swimming from June to September; Kazbegi and Svaneti are mountain climates where snow can fall in any month above 2,000 metres and the high passes close for part of the year. There is no single “best month for Georgia” — it depends on which of these five places you are heading to.

As a rule of thumb: late May, June and September are the most forgiving months almost everywhere, combining warm days, manageable rain and (in the mountains) open roads. July and August bring the most reliable sea-swimming weather to Batumi but also the country’s heat and humidity peaks. December to March is ski and snow-landscape season in Kazbegi, Svaneti and Bakuriani, and the time when Ushguli and some military-highway sections are hardest to reach. Figures below are long-run averages, not forecasts; always check the official sources linked in each section before you travel, since any single year can run warmer, colder or wetter than normal.

Tbilisi by month

Tbilisi has a transitional climate — hot, fairly dry summers and short, mild-to-cold winters with occasional snow that rarely settles for long. Spring and autumn are the most comfortable seasons for walking the Old Town and day trips such as Tbilisi & Mtskheta — The Essential First Day.

For current readings and short-range forecasts, verify against the National Environment Agency of Georgia, which runs the country’s hydrometeorological network.

Batumi and the humid coast by month

Batumi is one of the wettest cities on the Black Sea, with rain possible in any month — autumn and early winter bring the heaviest totals. Humidity stays high year-round, which makes July and August feel hotter than the thermometer suggests. Our Batumi & the Ajara Mountains — 2 Days tour times most of its coastal walking for the cooler parts of the day for this reason.

Comfortable swimming generally runs from mid-June to late September, with the sea still mild enough for a quick dip into early October. Batumi’s humidity and rain pattern are consistent with its classification as a humid subtropical climate, a point often noted in coverage of the Black Sea coast by outlets such as BBC travel and weather reporting.

Kazbegi and the Georgian Military Highway by month

Stepantsminda (Kazbegi), at roughly 1,740 metres, is noticeably colder than Tbilisi in every month and holds snow from late autumn into spring. The Jvari Pass section of the Georgian Military Highway is the main choke point: it can close temporarily after heavy snowfall or avalanche risk between November and April, and occasionally after summer storms. Day trips such as Kazbegi — Gergeti Trinity Church in a Day and the longer Kazbegi — 2-Day Mountain Journey are easiest to run between May and October.

Always check live conditions before driving: the Georgian Road Department publishes road and pass status at georoad.gov.ge, and our own road status page tracks the same closures in plain English for travellers booking with us.

Svaneti by month

Mestia sits at about 1,500 metres and Ushguli higher still, so winter arrives early and leaves late. Heavy snow typically closes or badly degrades the unpaved sections toward Ushguli from November into April, and even in a mild year a 4×4 and local judgement are needed outside midsummer. Mestia & Ushguli — 3 Days in Svaneti is built around the June-to-September window when all villages are reliably reachable.

Svaneti’s Upper Svaneti towers and villages are a UNESCO World Heritage property, and the site’s own documentation notes the remote, high-altitude setting that drives this weather pattern; see the UNESCO listing for Upper Svaneti.

Kakheti by month

Kakheti is warmer and slightly drier than Tbilisi in summer, with the same cold-but-manageable winters. The region’s calendar is built around the grape harvest, or rtveli, which usually runs from mid-September into October — our Rtveli — Wine Harvest in Kakheti tour and Kakheti Grand Wine & Heritage — 3 Days are both timed to this window.

Heatwaves and when the humid coast feels hottest

Tbilisi and Kakheti can see heatwave spells in July and August when daytime highs push toward 38–40°C for several days in a row; these are the months to plan museum visits, wine-cellar tours and the David Gareji desert trip for early morning or late afternoon. The combination of heat and humidity on the Batumi coast — rather than the raw temperature — is what makes late July and August feel most taxing there, since humidity regularly sits above 70 percent. People with heart or respiratory conditions, older travellers and young children are most at risk during these spells; Georgia’s public health authority issues seasonal heat advisories that are worth checking if you are travelling in peak summer, via the National Center for Disease Control and Public Health of Georgia. For any personal health concern linked to heat or altitude, see a doctor before you travel rather than relying on general guidance.

Best month for each region

• Tbilisi — May or late September to mid-October, for mild days and manageable rain.
• Batumi and the coast — June and September for warm sea with fewer crowds than peak August; July–August for the warmest water but the most humidity.
• Kazbegi — June to September, when the Georgian Military Highway and Jvari Pass are reliably open; shoulder months need a flexible itinerary.
• Svaneti — July and August for Ushguli access and trekking; June and September are good but check road conditions first.
• Kakheti — September and October for the rtveli harvest, or May for quiet vineyards and green hillsides.

Practical summary

• Tbilisi and Kakheti: hot, fairly dry summers (up to 38–40°C in heatwaves), mild winters with occasional light snow; best months May and September–October.
• Batumi: wet in every season, warm and humid June–September, sea swimmable roughly mid-June to early October; verify forecasts with the National Environment Agency before beach days.
• Kazbegi: snow possible November–April, Jvari Pass can close on short notice in winter; check georoad.gov.ge or our road status page before driving the Military Highway.
• Svaneti: Ushguli road often impassable December–April without 4×4 and chains; July–August is the safest planning window.
• Heatwaves peak July–August nationwide; plan outdoor time for morning or evening and watch official heat advisories if travelling with children, older relatives or anyone with a heart or lung condition.
• All figures are long-run averages for planning only; confirm live conditions through the official sources linked above before departure.
