Understanding the UV Index is crucial for residents of Novovasylivka, Ukraine, where sun exposure can significantly affect skin health. With climactic conditions that fall within the Dfb climate zone, the risk of harmful UV rays can peak during the day, reaching levels as high as 9 around midday. This makes awareness of daily UV levels essential for preventing sunburn and protecting long-term skin health. By keeping an eye on the UV Index, you can enjoy the beautiful Ukrainian sun while staying safe and radiant!

The zenith arrives at 12:00, where the index stands tall at 8, and by 13:00, it reaches a sizzling 9—the highest point of the day.

The evening brings relief as the UV Index transitions back down to 2 at 18:00 and finally returns to a mild 1 by 19:00.
