UV Index Georgia
According to the WHO, the average daily ambient ultraviolet radiation in Georgia is 2,489 J/m² (joules per square metre).
UV radiation overview
Georgia spans roughly 41.0–43.6°N on the eastern shore of the Black Sea, straddling the boundary between Eastern Europe and Western Asia. The Greater Caucasus range walls the north, culminating in Shkhara at 5,193 m, while the Lesser Caucasus rises in the south. Between them lies the humid subtropical Colchis lowland opening onto the Black Sea, with the drier Kura (Mtkvari) basin to the east. This compact territory packs coastal plains, mid-elevation valleys and very high alpine terrain into about 69,700 km², producing sharply varied UV exposure conditions.
A unique feature is the extreme altitude UV available on Greater Caucasus peaks above 5,000 m, with popular ski resorts like Gudauri operating at 2,200 m and higher, where thinner air and snow albedo amplify the UV index even in winter. In contrast, the subtropical humid Adjara coast around Batumi sees persistent low cloud and high humidity that attenuate surface UV. The Mtskheta-Mtianeti highlands sit above 2,000 m with frequent clear skies. The National Environmental Agency (NEA) under Georgia's Ministry of Environmental Protection coordinates meteorological and environmental monitoring nationwide.
Georgia sits at #151 of 191 in the WHO's global ambient-UV ranking with about 2,489 J/m² of average daily UV, around the 21st percentile worldwide.
