Understanding the UV Index in Normal, United States is crucial for protecting your skin and overall health. With peak levels reaching a dangerous 10 during the midday hours, awareness of UV exposure can help prevent painful sunburns and reduce the risk of long-term skin damage. Normal's Dfa climate brings a mix of sunny days and varying seasonal conditions, leading to significant UV exposure risks, especially in summer. By keeping an eye on the UV Index, you can enjoy the outdoors safely while safeguarding your skin’s health.
The UV Index data unveils a dynamic progression of sun intensity throughout the day. Starting low at 1 at 07:00, the index gradually escalates, reaching maximum levels of 10 between 12:00 and 14:00. This peak signals a critical time for sun protection. As the afternoon wanes, the index tapers off to 8 at 15:00, and then descends further to 3 by 17:00, and 2 by 18:00. Ultimately, the day concludes softly with a return to 1 at 19:00. It's essential to stay vigilant during those peak hours to safeguard your skin while enjoying the sun!

As the seasons change, so do the UV Index levels, significantly affecting sun exposure and burn times throughout the year. From January to February, UV levels remain moderate (3-5), allowing for a 30-minute burn time. However, starting in March, the UV Index rises to 7, indicating high exposure risk with burn times of 25 minutes. The peak risk occurs from April to June, where the UV Index hits 9-11, classifying these months as very high to extreme (with burn times reduced to 10-15 minutes). July and August maintain high levels of sun intensity, but begin to taper off in September (UV Index 8). By October, the UV Index decreases to 6, marking a return to high exposure risk, while November and December offer moderate to low levels (4 and 2 respectively), allowing for longer burn times. Visitors and residents are advised to take extra precautions during high-risk months (March to September) by wearing protective clothing and applying sunscreen regularly, particularly when UV levels are at their peak.
