Understanding the UV Index in Shidu, China, is crucial for maintaining skin health and preventing sunburn, particularly given its Dwa climate, characterized by hot summers and significant sunlight exposure. The UV levels can soar, peaking at an index of 10 around noon, which poses serious risks for skin damage and long-term health issues if protective measures are not taken. Being aware of these UV levels empowers residents and visitors alike to enjoy outdoor activities while safeguarding their skin with appropriate sun protection.
As the sun rises, the UV Index gradually transitions from a mild 1 at 07:00 to an invigorating 3 by 08:00. The peak UV intensity hits its stride between 12:00 and 13:00, reaching a striking 10, a clear call for sun protection. As the afternoon progresses, the index begins to decline, tapering off to 8 at 14:00, 6 at 15:00, and eventually settling to a gentle 2 by 17:00. By evening, the UV levels dip back down, returning to a safe 1, indicating it's time to relax and enjoy the cooler, softer light of sunset.
