🔆 UV Radiation in Georgia

UV Radiation in Georgia

The UV Radiation indicator measures the average annual UV index as a proxy for sun exposure and skin cancer risk. Note: a higher score here means lower UV exposure – i.e. a healthier situation. With a score of 64/100, a raw value of 5 (mean annual UV index), and world rank 32 out of 231, Georgia is in the moderately favourable mid-range globally.

What a UV Index of 5 Means

A mean annual UV index of 5 corresponds to the level of Central Europe – not extreme, but no free pass either. Georgia has a pronounced seasonal variance:

• Summer (June–August): UV index 7–9 in Tbilisi, up to 10+ at elevations above 2,000 m; sun protection is essential in high mountain terrain
• Spring / Autumn: UV index 4–6; sun protection recommended for extended outdoor stays
• Winter: UV index 1–2; low

Altitude Effect

For Georgia's mountain regions (Kazbegi, Svaneti): UV index increases by approximately 10% per 1,000 metres of altitude. At elevations above 3,000 m, UV protection measures (SPF 50+, sunglasses) are essential.

Compared to Other Regions

• Estonia (78), Norway (78), Finland (78): Very low UV index in Northern Europe
• United Kingdom (71), Canada (71): Northern Hemisphere mid-range
• United States (64), Georgia (64), Armenia (64): Medium level
• Portugal (57), Turkey (57): Slightly higher UV exposure in the south
• Thailand (43), Singapore (43): Tropically high UV values

Relevant for Expats

In daily life in Tbilisi, UV protection during summer months is sensible but not extreme. For hiking and mountain tours in Racha, Svaneti, or Kazbegi, consistent sun protection (SPF 50+ sunscreen, UV-protective clothing, sunglasses) is important.

Conclusion: UV index 5 and score 64/100 describe a pleasantly moderate sun exposure level – cool enough for comfortable city living, sunny enough for an active outdoor lifestyle, with clear precautions needed for mountain tours.
