In Clio, United States, awareness of the UV Index is crucial for maintaining your skin health and preventing sunburns. Understanding the UV levels throughout the day helps residents take necessary precautions against harmful ultraviolet radiation, particularly during peak hours when the index soars to 11 from noon to 1 PM. With Clio's temperate climate (Cfa), the potential for high UV exposure is significant, making it essential to stay informed and protect your skin. Whether you're enjoying outdoor activities or simply soaking up the sun, knowing the UV Index can empower you to make smarter choices for your health.
The UV Index throughout the day paints a vivid picture of the sun's intensity. At 7:00 AM, the day begins with a gentle UVI of 1, making it safe for early risers. By 8:00 AM, it ticks up to 2, still in the low range. As the sun climbs higher, the index jumps to 4 at 9:00 AM, indicating a moderate level of UV radiation. The peak arrives at 12:00 PM and 1:00 PM, where the index soars to an alarming 11, highlighting the need for sun protection during these hours. Fortunately, as the afternoon progresses, the levels start to decline, dropping to 10 by 2:00 PM and then to 7 and 5 through 3:00 PM and 4:00 PM. By 5:00 PM, it settles back to 2, and by 6:00 PM, a return to the safer 1 concludes a day dominated by high UV intensity. Remember, at high levels, sun safety is vital!

Throughout the year, UV Index levels fluctuate significantly, with the highest risk observed during the spring and summer months. From February to August, the UV Index remains at a very high to extreme level, peaking at 11 in May, June, July, and August, where the burn time is as short as 10 minutes. Visitors and residents are advised to take extra precautions during these months by wearing protective clothing, applying sunscreen regularly, and seeking shade, especially during midday hours. In contrast, January and December experience moderate UV levels, allowing for longer exposure times of 30 minutes before burning. As the UV levels decline entering the fall months, particularly in November with a high index of 6 (burn time of 25 minutes), it is still prudent to remain vigilant against UV exposure.
