Understanding the UV Index in Xuhui, China, is essential for safeguarding your skin and enhancing overall health. With peak UV levels often reaching an intense 11 around midday, awareness of these fluctuations can help prevent sunburn and long-term skin damage. Xuhui’s humid subtropical climate (Cfa) presents unique challenges, especially during the summer months when sun exposure is at its highest. By regularly checking the UV Index, residents and visitors can take proactive steps to protect themselves, ensuring that their time outdoors remains enjoyable and safe.
The UV Index throughout the day presents a dynamic picture of sun exposure. As early as 7:00 AM, the index starts at a mild 2, ramping up to a moderate 4 by 8:00 AM. The sun's intensity peaks around 11:00 AM and 12:00 PM with a striking 11, marking the height of caution for outdoor activities. As we move into the afternoon, the index gradually declines, dropping to 8 by 2:00 PM and further to 5 by 3:00 PM. The evening brings relief, with the UV Index decreasing to a 1 by 5:00 PM and finally hitting 0 by 7:00 PM. It’s clear that the midday hours pose the greatest risk, so sun safety measures are essential during those peak times.
