The high-risk months of April through August peak at a very high UV index of 8, necessitating strict sun protection measures as burn time drops to just 15 minutes. July and August maintain high levels at 6-7, allowing for 25 minutes of sun exposure. As autumn arrives, the risk decreases, with September and October showing moderate UV indexes (5-3) and longer burn times of 30 minutes. By November and December, the index returns to low levels, providing ample burn time once again at 45 minutes. Visitors and residents are advised to wear sunscreen and protective clothing during higher UV months, particularly between April and August, when the risk of skin damage is significantly elevated.
