Being aware of the UV Index is crucial for residents of Burnet, United States, where the warm Cfa climate brings both sunshine and potential skin risks. Understanding UV levels can significantly aid in sunburn prevention and overall skin health. During peak hours, especially between 10 AM and 2 PM, UV exposure can reach as high as 12, indicating a high risk for harm without proper protection. By staying informed about daily UV levels, Burnet residents can enjoy the sun while effectively safeguarding their skin against the dangers of overexposure.
The UV Index throughout the day reveals a dramatic rise in sun exposure, peaking during the afternoon. Starting with a modest 1 at 07:00 and 08:00, the intensity gradually escalates, reaching 5 by 10:00. By 11:00, it jumps to a striking 7, and by noon, it explodes to a scorching 10. The hottest hours hit their zenith at 12:00 and 13:00, with a relentless 12, indicating high risk for unprotected skin. As the sun begins its descent, the index gradually declines, dropping to 10 by 15:00, then to 8 by 16:00. As the evening rolls in, the UV Index returns to a safer 5 at 17:00 and then gradually falls to 3 and 1 by 18:00 and 19:00, respectively. For outdoor enthusiasts, it’s essential to seek shade and apply sunscreen during those peak hours to enjoy the sun safely!
