Understanding the UV Index is crucial for residents of Keota, United States, as it provides important insight into the potential risks of sun exposure throughout the day. Being aware of UV levels helps in preventing sunburns and protecting skin health, which is essential in maintaining overall well-being. Given Keota's Cfa climate, which brings warm summers and ample sunshine, the UV Index can soar, reaching levels as high as 11 in midday hours. This makes it vital for locals to stay informed about UV exposure risks to enjoy the sun safely while safeguarding their skin.
The UV Index throughout the day presents a clear trajectory of increasing intensity, peaking dramatically as the sun reaches its zenith. At 07:00, the index starts modestly at 1, signifying minimal risk. However, as the hours roll on, from 08:00 to 10:00, it climbs steadily to 6, marking the onset of moderate exposure. The real surge occurs between 11:00 and 13:00, where the index hits a staggering 11, indicating a very high risk for unprotected skin. Even as it begins to taper off in the afternoon—returning to 9 by 15:00 and further down to 4 by 17:00—the day's UV intensity serves as a reminder of the importance of sun protection. By 19:00, it drops back to a safe 1, allowing for a sigh of relief as daylight wanes. Embrace the sun wisely!
