In Roselawn, United States, being aware of the UV Index is vital for protecting your skin and overall health. Understanding the UV levels throughout the day can help prevent painful sunburns and long-term skin damage. With Roselawn's humid continental climate (Dfa), residents often face elevated UV exposure, particularly between 10 AM and 3 PM when the index peaks. By staying informed and taking necessary precautions, you can enjoy the sunshine while keeping your skin safe!
As the sun rises, the UV Index starts its climb, peaking spectacularly around midday. At 07:00, it registers a mild 1, barely a whisper of sunlight.

However, the real intensity hits at 10:00, where the index reaches 7, a clear indication that the sun is getting serious. At 11:00, it surges to a striking 9, and by 12:00 and 13:00, it reaches its zenith at 10—a moment to take shade and apply sunscreen diligently! 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!
