UV Index 🇸🇪Sweden

Sweden stretches from about 55°N at its southern tip near Smygehuk to 69°N at Treriksröset in the far north, placing the entire country at high latitudes well outside the tropics. The shallow sun angle through much of the year keeps the long-term average UV intensity very low by global standards. Sweden is one of the lowest-UV countries in the world according to the WHO's ambient-UV dataset, despite long summer days that briefly push the daily UV index into the moderate-to-high range across the south.

The Arctic Circle crosses Swedish Lapland, and north of it the sun does not set for part of summer and does not rise for part of winter. In Stockholm, daylight lasts more than 18 hours in late June but only around 6 hours in late December, so summer UV is delivered in a long, drawn-out exposure window while winter UV effectively disappears. The result is one of the planet's sharpest seasonal UV swings — high contrast, but never tropical-style intensity.

Sweden ranks #186 of 191 in the WHO's global ambient-UV ranking with about 1,587 J/m² of average daily UV, around the 3rd percentile worldwide.
