In Oslo (59.9° latitude), April 2026 has 30 days whose sun rises at 06:47 and sets at 19:56 on the 1st, and at 05:20 and 21:09 on the 30th. Mid-month the day lasts 14 h 27 min and the sun reaches 39° above the horizon. Even so, the UV index never reaches 3 at any point in the month: at this latitude and time of year, the ozone layer absorbs UVB before enough of it reaches the ground.
