Weather in Tbilisi

In Tbilisi the seasons run: about +8° by day in winter, +18° in spring, +30° in summer, +19° in autumn. The warmest month is August (up to +32° by day), the coolest is January (+7°). Most rainfall is in April. Detailed monthly normals are in the table below.

In summer it's up to +30° by day and about +19° at night: light clothes for the day, a jumper for the evening. In winter it's +8° by day and down to 0° at night — bring a warm coat. The driest month is August — the clearest time for walks and wide-open views.

Tbilisi is open year-round: museums, sulphur baths and restaurants never close. The most comfortable months are September, May, June — summer days reach +30° and the cobblestones bake, winters (+8°) are quiet. The old-town walk is Old Tbilisi walking tour.

Tbilisi sits in a basin on the Kura river, so summers here run 3–4°C hotter than the surrounding mountains. I take guests through the Old Town early in the morning or after 5 pm — in the July heat the cobblestones of Abanotubani bake, and the shade of the narrow lanes is a relief.

Tbilisi lies in a basin along the Mtkvari river, and in summer the city heats up more than its surroundings: in July–August daytime highs are often +33…+35 °C, and stone and asphalt hold the heat well into the night. So in summer I start old-town walks at 9–10 am or towards evening, and in the heat the funicular up Mtatsminda helps — the park there is about 300 metres above the centre and noticeably fresher.

Winter is mild: snow falls a few times a season and usually melts within a day or two. The wind makes it feel colder than the thermometer says — Tbilisi is often windy, especially in spring. The best plan for a raw, grey day is the sulphur baths of Abanotubani. The most pleasant months for walking are May, June, September and October; in October the city celebrates Tbilisoba.
