Tbilisi Weather in August
Tbilisi weather in August edges out July as the hottest of the year, if only by a fraction. Average highs sit at about 32 °C (90 °F), nights stay near 20 °C (68 °F), and rain is scarce at around 39 mm on five days. The change you notice is the light: sunset now comes around 20:03, about half an hour earlier than in July. September then drops five degrees and feels like relief.
What to wear in Tbilisi in August
Dress as you would in July: loose, light fabrics, a hat and high-factor sunscreen. Heading into the mountains for a few days? Add a fleece and a rain jacket, since Kazbegi evenings can fall close to 10 °C. Comfortable sandals plus one pair of closed shoes cover both city and trail.
What August is good for
With the city at its warmest, many locals leave for the hills, and you can follow. Stepantsminda, below Mount Kazbek, offers fresh mountain afternoons and cools to 11 °C after dark; Gudauri manages around 19 °C. In Kakheti, Telavi reaches roughly 31 °C, so start early. Didgoroba is marked at the Didgori Battle Memorial on 12 August, and Mariamoba on 28 August is a public holiday with pilgrimages to churches of the Virgin. Evenings in town suit Rike Park and the Narikala Cable Car.
