During the year, UV exposure changes significantly, with the highest risks occurring from February to October, where the UV Index consistently falls in the extreme category, peaking at 15 in May, July, and August. This poses a very short burn time of merely 10 minutes, making these months particularly hazardous for skin health. Conversely, January, November, and December present a lower risk with a UV Index ranging from 8 to 9 and a longer burn time of 15 minutes, indicating relatively safer conditions. Visitors and residents should exercise caution and take protective measures, especially during the high-risk months, by wearing sunscreen, protective clothing, and seeking shade during peak sunlight hours to minimize harmful UV exposure.
