Understanding the UV Index in Clark, United States, is crucial for maintaining skin health and preventing sunburn. With the climate classified as Dfa, residents experience distinct seasons, but the risk of high UV levels, especially during peak hours from 11 AM to 3 PM, can’t be overlooked. During these times, UV Index values soar, reaching a maximum of 9, signaling a need for protective measures. By being aware of UV levels, you can protect yourself and your loved ones from harmful effects of overexposure, ensuring fun-filled days under the sun while prioritizing skin safety.
Today’s UV Index paints a vivid picture of sun intensity as it climbs to its peak during midday. Starting from a gentle 1 at 07:00 and 08:00, the sun begins to rise in strength, reaching a 3 by 09:00.
