In the beautiful Koskullskulle, Sweden, being aware of the UV Index is crucial for protecting your skin and overall health. Understanding UV levels helps in preventing sunburn and reducing the risk of long-term skin damage, which is particularly important given the area's cool climate (Dfc) and varying sun exposure throughout the year. On sunny days, UV levels can soar to a maximum of 5 around midday, making it vital to stay informed and take necessary precautions. By keeping an eye on the UV Index, you can enjoy the outdoors while safeguarding your skin from harmful rays.

By 10:00 AM, it reaches a moderate 4, peaking at a solid 5 from 11:00 AM to 2:00 PM, indicating a great need for sun protection during these hours. As the afternoon wears on, the intensity begins to wane, with levels dropping back to 4 by 3:00 PM, and further decreasing to 3 at both 4:00 PM and 5:00 PM. By 6:00 PM, the index falls to 2, and finally settles at just 1 as twilight approaches at 7:00 PM.
