The UV Index experiences notable fluctuations throughout the year, influencing both sun exposure and risk levels for skin damage. During the winter months, from December to February, the UV Index remains low (1-2), allowing for longer burn times of 45 minutes, making this a relatively safer period for sun exposure. However, as spring approaches, particularly in March, the UV levels rise to a moderate index of 4, indicating the need for increased caution with a reduced burn time of 30 minutes. The high-risk months occur from late spring to mid-summer, with May reaching an index of 7 and June and July peaking at 8, categorized as very high, significantly shortening safe exposure to just 15 minutes. As summer transitions to fall, the risk reduces but remains considerable in August (UV Index 7) and September (UV Index 6), before tapering off in the fall months of October through December. Visitors and residents are advised to protect their skin during high UV periods by wearing sunscreen, hats, and protective clothing, particularly in the peak months from April to August.
