Understanding the UV Index is crucial for residents of Hayes Center, as it provides essential information on the level of ultraviolet radiation reaching the Earth's surface. Awareness of UV levels is key to preventing sunburn and protecting skin health, especially during the summer months when Hayes Center's climate brings higher sun exposure. With UV Index levels in the afternoon peaking at 11, it’s important to take precautions to safeguard against the harmful effects of prolonged sun exposure. Knowing when to seek shade or apply sunscreen can make a significant difference in your overall skin wellness and enjoyment of the sunny days ahead.
The UV Index begins its day gently, peaking at a maximum of 1 at 7:00 AM and holding steady until 9:00 AM when it climbs to 2. As the sun reaches its zenith, the index surges dramatically, hitting 5 by 10:00 AM and soaring to its peak of 11 at both 1:00 PM and 2:00 PM. This period marks the hours where sun protection is critical. As the afternoon progresses, the index gradually descends, dropping to 10 by 3:00 PM, then tapering off to 8 at 4:00 PM, and continuing its decline until reaching 2 by 7:00 PM. It's a vivid reminder that while the sun graces us with its warmth, vigilance against UV exposure is essential during peak hours.
