Understanding the UV Index in Graham, United States, is crucial for maintaining skin health and preventing sunburn. With peak UV levels soaring as high as 11 during midday hours, residents must be aware of the potential risks associated with sun exposure. Graham's Cfa climate brings warm summers, making it essential to monitor UV levels during outdoor activities. By keeping an eye on the UV Index, you can enjoy the sun safely while protecting your skin from harmful rays.
The UV Index throughout the day exhibits a remarkable peak, beginning at a low 1 in the early hours, gradually rising to 5 by 10:00. As the sun reaches its zenith, the index soars to an impressive 10 at 12:00, hitting a maximum of 11 from 13:00 to 14:00. This intense exposure makes midday the most critical time for sun protection. As the afternoon progresses, the index begins to dip, falling to 7 at 16:00, and winding down to a gentle 3 by 18:00. By 19:00, the UV Index drops back to 1, signaling a return to safer sun conditions. Planning outdoor activities? Make sure to take precautions from late morning to mid-afternoon, when the sun’s rays are most powerful!
