UV Index Greece
According to the WHO, the average daily ambient ultraviolet radiation in Greece is 2,753 J/m² (joules per square metre).
UV radiation overview
Greece extends from the islet of Gavdos south of Crete at roughly 34.8° N to the Prespa lakes near 41.7° N on the North Macedonian border, giving it one of the longest north-south spans in the Mediterranean Basin. The coastline is the most deeply indented in Europe, threading around some 6,000 islands and islets across the Aegean and Ionian seas, while the mainland is dominated by the Pindus range and capped by Mount Olympus at 2,917 m, the country's highest summit.
Crete and Gavdos mark the southernmost land in Europe, so noon UV index values over the southern Aegean routinely reach 9–10 in midsummer under the clear, dry skies that accompany the Etesian (meltemi) winds sweeping down from the north. The Hellenic National Meteorological Service (HNMS/EMY) issues a daily UV forecast for the country, and the WHO/WMO note that the thinner atmosphere over the high Pindus and the Olympus massif, combined with strong reflection off the sea surface around the islands, further boosts effective UV exposure.
Greece sits at #143 of 191 in the WHO's global ambient-UV ranking with about 2,753 J/m² of average daily UV, around the 25th percentile worldwide.
