Throughout the year, the UV Index experiences significant changes, particularly peaking in the first half. January starts with a UV Index of 10, categorized as very high, where a burn can occur in just 15 minutes. However, the intensity escalates dramatically from February to April, with the UV Index reaching a maximum of 15 in March, classified as extreme, necessitating vigilance as burn times shrink to just 10 minutes. This high-risk period continues through May, June, July, and into August, with similar UV levels persisting and caution advisable. As the year progresses into the fall, the UV Index remains elevated, particularly in September and October, yet begins to taper off by November and December with a return to very high levels but longer burn times of 15 minutes again. Visitors and residents are advised to take necessary precautions—such as wearing sunscreen, protective clothing, and seeking shade—especially during the peak months from February to October when UV exposure poses a greater risk.
