Understanding the UV Index in Mountain Green, United States is essential for protecting your skin and overall health. With typical summer temperatures and clear skies, the UV radiation levels can spike significantly, peaking at 12 from 1 PM to 2 PM, which poses a high risk of sunburn. By staying informed about the UV levels throughout the day, residents and visitors can take proactive measures to prevent overexposure, ensuring their outdoor activities remain enjoyable and safe. In this beautiful climate zone, where outdoor adventures abound, being aware of UV Index changes can make all the difference in safeguarding your skin health.
At dawn, the UV Index starts off gentle, peaking at 1 by 07:00. As the sun rises higher, its intensity escalates dramatically, reaching 6 by 10:00 and soaring to a blistering 12 at 13:00—the highest point of the day. From then, the index begins a gradual descent, tapering to 10 by 15:00, followed by 8 at 16:00, and finally falling back to 1 by 19:00. This dynamic pattern highlights the importance of sun protection during midday hours, when UV exposure is at its most intense, especially between 11:00 and 14:00. Stay safe and enjoy the sunshine responsibly!
