🌧️ Rainy Days in Georgia

Rainy Days in Georgia

Georgia averages 105 rainy days per year (days with at least 1 mm precipitation) nationally. This mean, however, conceals one of the most extreme regional precipitation distributions in all of Europe: the ratio between the rainiest and driest regions approaches five to one. For anyone considering relocation, the choice of residence is therefore a decisive factor in daily life — the difference between Batumi and Tbilisi is climatically as vast as the difference between Seattle and Phoenix. The Georgian National Environmental Agency (NEA) operates the official precipitation monitoring network that provides the data below.

Batumi: Among the Rainiest Cities in Europe

The Adjaran port city of Batumi receives approximately 2,400 mm of precipitation per year — spread across up to 170 rainy days. This exceeds Bergen, Norway (2,250 mm) and places Batumi among the wettest cities on the continent. The cause is orographic: moist air masses from the Black Sea are forced upward by the coastal Meskheti Range (up to 2,850 m) and precipitate. September and October are particularly extreme: single events of 100–150 mm within 24 hours are documented, regularly causing flash floods in the old town. The Adjaran Agency for Disaster Management publishes annual reports on flood damage — in 2023, Batumi alone sustained approximately 15 million GEL (about 5 million USD) in infrastructure damage.

For daily life, this means: in Batumi, weatherproof clothing is needed year-round, and apartment seekers should avoid ground-floor units on slopes. Mold problems in poorly ventilated apartments are a well-known issue along the coast.

Tbilisi: Surprisingly Dry

The capital is relatively dry with only about 500 mm of precipitation per year and roughly 100 rainy days — comparable to Los Angeles (380 mm) in overall feel, though distributed differently. Dryness peaks in midsummer: July and August average only 20–30 mm, with rainy days rare (5–7 per month). Most precipitation falls in May and June (60–80 mm/month), often as brief, intense afternoon thunderstorms. Winters are relatively dry (December–February: 20–30 mm each), and snow falls in the city on 10–15 days per year, rarely persisting more than 2–3 days. The Ministry of Environmental Protection and Agriculture of Georgia documents a slight decline in spring precipitation since 2000, which is relevant for the city's water supply.

Kakheti: Seasonal Rain

The wine region receives approximately 700 mm of precipitation per year, concentrated mainly in spring (April–May) and autumn (October–November). Summer brings only 30–50 mm per month, which is ideal for winemaking — the grapes need the dry conditions of the ripening period (August–September). The National Wine Agency reports that vintages with above-average summer rain (such as 2015, with 90 mm in August) lead to quality reductions in Rkatsiteli wines. For residents, the seasonal pattern means: expect muddy field roads in spring and dust clouds on unpaved roads in summer.

Svaneti: Heavy Rain and Snowmelt

The mountain region of Svaneti (Mestia, Ushguli) receives 1,000–1,400 mm of precipitation annually, with April through June being the most intense months. The combination of snowmelt and heavy rain regularly triggers mudslides and landslips during this period. The Georgian National Geological Survey documents an average of 15–20 erosion-relevant events per year in the Svaneti region. In autumn 2023, a mudslide destroyed the access road to Ushguli for three weeks — such events are part of daily life for mountain communities. In winter, precipitation falls as snow: the snow cover in Mestia (1,500 m) reaches 50–100 cm, in Ushguli (2,200 m) up to 200 cm.

Colchic Lowland: Consistently Wet

The lowland between Kutaisi and Zugdidi receives 1,200–1,800 mm of precipitation per year. Distribution is relatively even with a slight autumn peak. Kutaisi itself (Georgia's second city, population approximately 150,000) records around 130 rainy days per year. The region was historically Georgia's breadbasket, and the rainfall continues to support intensive cultivation of corn, hazelnuts (Georgia ranks among the world's top-5 producers according to FAO) and tea.

Comparison with English-Speaking Countries

For reference: London receives approximately 600 mm across 110 rainy days, New York about 1,200 mm on 120 days, Sydney roughly 1,200 mm on 100 days, and Toronto around 830 mm on 135 days. Georgia's national average sits in a similar range to London, but the internal variation is enormous. Someone relocating from London to Batumi faces a quadrupling of precipitation. Conversely, Tbilisi feels remarkably dry compared to most major cities in the UK, the US Northeast, or eastern Canada.

Practical Tips

In Batumi, expect multi-day rain events during the off-season (October–December) and check apartment drainage before signing a lease. In Tbilisi, an umbrella for the occasional summer thunderstorm suffices — the city offers plenty of covered passages in the old town. Anyone living in mountain regions must plan for road closures from April through June and keep emergency supplies on hand. The NEA recommends monitoring local weather warnings via the Georgian Weather Service app (meteo.gov.ge), which has been available in English since 2022.
