Throughout the year, UV Index levels fluctuate, with the highest readings observed from March to October, where the Index consistently remains in the extreme category. The peak occurs in May, July, and August, reaching UV Index 14 and necessitating a burn time of just 10 minutes before skin damage can occur. The high-risk months are therefore considered February through October, particularly as exposure risks elevate during this period. As such, it is crucial for visitors and residents to take precautions during these months, such as wearing protective clothing, applying broad-spectrum sunscreen, and seeking shade during peak hours to minimize UV exposure and protect skin health. In contrast, January, November, and December see slightly lower levels, categorized as very high, but precautions should still be observed with burn times extending to 15 minutes.
