UV Index Estonia
According to the WHO, the average daily ambient ultraviolet radiation in Estonia is 1,781 J/m² (joules per square metre).
UV radiation overview
Estonia lies in northern Europe between roughly 57.5° and 59.7° N, putting it among the higher-latitude states of the European Union. The territory is overwhelmingly low and flat: the highest point, Suur Munamägi in the southeast, reaches just 318 metres, and most of the country sits below 100 metres. Estonia borders the Baltic Sea to the west and the Gulf of Finland to the north, giving it an extensive, indented maritime coastline that shapes its climate and atmospheric conditions year-round.
A distinctive feature of Estonia is its archipelago: the country includes more than 2,000 islands and islets in the Baltic Sea, with Saaremaa and Hiiumaa being the largest. Sitting close to the 60° N parallel, Tallinn experiences around 19 hours of daylight at midsummer and very short, dim days in winter. The historic Tartu Observatory has a long tradition of atmospheric and astronomical monitoring, and today the Estonian Environment Agency (Keskkonnaagentuur, formerly EMHI) issues the national UV index forecast under a persistent Baltic cloud regime.
Estonia sits at #178 of 191 in the WHO's global ambient-UV ranking with about 1,781 J/m² of average daily UV, around the 7th percentile worldwide.
