The UV Index is a crucial factor for residents and visitors in Xiejiapu, China, where understanding sun exposure is vital for preventing sunburn and maintaining overall skin health. With a humid subtropical climate (Cfa), Xiejiapu experiences peak UV levels, reaching a maximum of 12 around noon, suggesting a high risk of harm to unprotected skin. By being aware of the UV Index throughout the day, you can take essential precautions—like wearing sunscreen and protective clothing—during those hours when UV radiation is at its highest, ensuring your time under the sun is both enjoyable and safe.
The hourly UV Index paints a vivid picture of sun intensity throughout the day. In the early hours, from 07:00 to 08:00, the UV exposure remains low, peaking at a mere 2. However, as the sun climbs higher, from 09:00 to 11:00, the index surges, reaching a notable maximum of 12 by 12:00. This is the moment to take precautions! The UV levels begin to slightly drop by 14:00, settling at 10, before gradually tapering off as evening approaches. By 17:00, it diminishes to 3, and after 18:00, we return to a much safer level of 1. It's a reminder to stay vigilant during the midday hours, when the sun is at its strongest!
