In Hanonu, Turkey, being aware of the UV Index is crucial for protecting your skin and overall health. Understanding the levels of ultraviolet radiation can significantly aid in preventing sunburn and reducing long-term skin damage, especially during the intense midday sun when UV levels peak at an impressive 10. With a Cfb climate, Hanonu experiences distinct seasonal variations, but the potential for high UV exposure remains a consistent risk. By staying informed about the daily UV Index, you can enjoy the warm Turkish sunshine while safeguarding your skin against harmful rays.

However, the real intensity hits at 10:00, where the index reaches 7, a clear indication that the sun is getting serious.

The afternoon sees a gradual decline, with levels easing to 9 at 14:00, and 7 by 15:00. As the day winds down, the index descends to 5 at 16:00, 3 at 17:00, and returns to a gentle 1 by 19:00, wrapping up a day of fluctuating sun intensity. Remember, during those peak hours, protecting your skin is essential!
