In Chencang, China, awareness of the UV Index is crucial for safeguarding your health under the intensity of the sun. Understanding the daily UV levels helps residents and visitors alike to prevent sunburn and protect skin health, especially when exposure can reach a peak index of 11 around midday. Given Chencang's Cwb climate—characterized by warm, temperate conditions—the risk of harmful UV radiation is significant during the summer months, making it essential to stay informed and take necessary precautions to enjoy the outdoors safely.
As the sun rises, the UV Index begins its ascent, peaking at 11 between noon and 1 PM, signaling a moment when sun protection is vital. Early in the morning, the index starts low, with a mere 1 at 7 AM, gradually climbing to a moderate 4 by 9 AM. By 10 AM, the levels ramp up to 7, warning of increasing risk as lunchtime approaches.
