UV Index 🇵🇱Poland

Poland stretches across the North European Plain between roughly 49°N at the Tatra crest and about 55°N on the Baltic coast, a span of around 649 km from north to south. At these mid-to-high latitudes the noon sun stays below 65° even at the summer solstice, so UV is strongly seasonal: winter days deliver weak UV under low sun and frequent overcast, while late-spring and summer noon hours dominate the annual exposure budget under transitional maritime-continental air masses.

Poland's UV regime spans an unusual vertical range for a Central European country. The Polish Tatras hold the only alpine landscape along the entire 1,200 km Carpathian arc, with Rysy at 2,500 m and 70 peaks above 2,000 m, where thinner atmosphere, frequent snow cover, and clearer summer skies push surface UV well above lowland values. By contrast, the 528 km Baltic coast and the flat Polish Plain receive more uniform, cloudier UV moderated by maritime air, while the Belsk Duży observatory in Masovia anchors long-running ozone and UV monitoring over the Central European lowlands.

Poland sits at #179 of 191 in the WHO's global ambient-UV ranking with about 1,749 J/m² of average daily UV, around the 6th percentile worldwide.
