The UV Index varies significantly throughout the year, with the highest levels occurring from January to April, where it reaches a striking 16, classified as extreme, meaning a burn time of just 10 minutes. February and March maintain this heightened risk, while April sees a slight drop to 12 but remains in the extreme category. As spring transitions into summer, the risk decreases, with May and June exhibiting very high to high levels with burn times increasing to 15-25 minutes. However, September to November sees a resurgence in risk, particularly with 12 in September, 14 in October, and peaking at 15 in November, all maintaining the extreme classification. December equals January’s maximum UV risk of 16.
