Understanding the UV Index in Visby, Sweden is essential for maintaining skin health and preventing sunburn, especially during the sunnier months. With a typical climate classified as oceanic (Cfb), residents and visitors alike should be aware that UV levels can reach a peak of 7 around noon, indicating a moderate to high risk for unprotected skin. By staying informed about daily UV fluctuations—from a low 1 in the early morning to a peak 6-7 during midday—individuals can take necessary precautions to safeguard their skin and enjoy the beautiful Swedish sun responsibly.
The UV Index throughout the day paints a vivid picture of sun intensity, peaking during midday hours. At 07:00, it starts at a mild level of 1, gradually rising to 2 by 08:00. As the morning progresses, it reaches 4 at 09:00, and by 10:00, it climbs to a noteworthy 5. The sun bears down most fiercely between 11:00 and 12:00, with the UV Index hitting 6 and then its highest point of 7. This peak intensity continues until 13:00, before gradually tapering off. By 14:00, the index slips back to 6, and then to 5 at 15:00. The late afternoon brings further relief as the index descends to 4 at 16:00, followed by 3 at 17:00. As evening arrives, the numbers dwindle, landing back at a gentle 1 by 19:00. Be mindful of this UV journey to stay safe in the sun!
