The UV Index is a crucial measure for residents of Xinhua, China, helping to safeguard against the harmful effects of ultraviolet radiation. Understanding UV levels is essential for preventing sunburn and maintaining long-term skin health, especially in a region where the Cwb climate brings warm summers and increased sun exposure. With UV Index levels soaring as high as 15 during peak hours, it’s vital for locals and visitors alike to stay informed and take protective measures to enjoy the sun safely.
As the sun rises, the UV Index starts at a gentle 1 at 07:00, making it a safe time for morning activities. By 08:00, it nudges up to 2, and things heat up quickly, reaching a striking 4 by 09:00. The real intensity kicks in at 10:00, where it soars to 7, and by midday at 12:00, it peaks at 13—a level that calls for caution! The UV radiation reaches its utmost at 13:00, hitting an impressive 15. After this zenith, a gradual decline begins, with 14:00 showing 14, followed by 11 at 15:00. As afternoon transitions to evening, the index dips to 8 by 16:00, and returns to a benign 4 at 17:00. By 18:00, it settles at 2, and finally back to 1 by 19:00, wrapping up the day with a sense of safety as the sun sets. Be sure to protect your skin during those peak hours!
