In Beihai, China, being aware of the UV Index is crucial for safeguarding your skin from harmful ultraviolet rays that can lead to sunburn and long-term health issues. Understanding the UV levels not only empowers residents and visitors to take necessary precautions but also promotes overall skin health. Beihai's Cwb climate brings warm summers and mild winters, often exposing individuals to elevated UV ratings, particularly during midday when indices can reach as high as 14. Being informed about these levels helps you enjoy the beautiful outdoors while protecting yourself from potential risks associated with excessive sun exposure.
The UV Index is a crucial indicator of sun exposure throughout the day, and today it tells a compelling story. Starting off gently at 1 by 07:00, the sun gradually intensifies, reaching 3 by 09:00. As the clock strikes 10:00, the index soars to 6, but it’s not until 11:00 that we hit the first peak of 10. The heat tops out at an impressive 14 at 13:00, showcasing the day's maximum sun intensity. Following this zenith, the index begins to decline, settling back to 11 by 15:00, before descending further to 2 by 18:00 and winding down to 1 as the day closes. To enjoy the sun safely during peak hours, remember to take protective measures when the UV Index reaches its highest levels!
