Understanding the UV Index is crucial for residents and visitors of Elmendorf Air Force Base, as it serves as a key indicator of the sun's harmful ultraviolet radiation levels. By being aware of UV levels, you can effectively prevent sunburn and protect your overall skin health from potential long-term damage. Elmendorf experiences a climate characterized by cold winters and mild summers, leading to unique UV exposure risks, particularly during the sunniest months when UV levels can reach up to 7 by early afternoon. Staying informed about the UV Index allows you to take proactive measures to enjoy the outdoors safely while safeguarding your skin.
At dawn, the UV Index begins its ascent, peaking at 1 by 7:00 AM. As the sun rises higher, it gently climbs to 2 by 9:00 AM, but the real intensity arrives at midday. By 12:00 PM, the index reaches 6, and it continues to soar to its maximum of 7 at 1:00 PM and 2:00 PM. As the afternoon progresses, the UV levels gradually taper off, descending to 5 by 4:00 PM and finally settling back to 2 by 7:00 PM. This data highlights the importance of sun protection during peak hours, particularly between 11:00 AM and 3:00 PM, when the UV exposure is most potent.
