The UV Index demonstrates significant seasonal variation, peaking during the warmer months from March through August, where values reach extreme levels (UV Index 10-12), particularly in May, June, and July. During these months, the burn time shortens to as little as 10 minutes, indicating a heightened risk of skin damage from sun exposure. High-risk months include March, April, May, June, July, and August, all marked by very high to extreme UV indices. Residents and visitors should take necessary precautions, such as wearing sunscreen, protective clothing, and seeking shade, especially during peak sun hours to reduce the risk of sunburn and long-term skin damage. As the index decreases in the fall and winter months, November and December present lower risks, with moderate levels and longer burn times of 30 minutes. Nonetheless, it is advisable to remain vigilant and protect the skin during all months of the year.
