The UV Index data reveals significant seasonal variations, with high-risk months predominantly occurring from January to April when the index remains at a strikingly high level of 15, categorized as extreme, resulting in a quick burn time of merely 10 minutes. As the year progresses into June and July, the index slightly decreases to 10, marked as very high, allowing for a somewhat longer burn time of 15 minutes. Visitors and residents should exercise extreme caution during these peak months by wearing protective clothing, sunglasses, and applying sunscreen frequently. In the latter part of the year, particularly from August to November, the UV levels still pose a risk, staying in the extreme category; therefore, regular sun safety practices are essential to prevent sunburn and long-term skin damage. Always remain vigilant, as a simple 10-minute exposure can lead to significant skin damage during these high-risk periods.
