As the seasons change, so do the UV Index levels, indicating varying risks of skin damage from sun exposure. January and February start at a moderate UV Index of 3 and 5 respectively, allowing a relatively safe burn time of 30 minutes. However, in March, the UV Index climbs to 6 (high), and April ramps up to 8 (very high), reducing burn time to just 15 minutes. The peak months of May through August maintain a critical UV Index of 9, portraying significant risk with the same short 15-minute burn time. As summer wanes into September and October, the risk remains high with UV levels at 7 and 6, respectively, but allows for a slightly more forgiving 25-minute burn time. By November and December, UV levels drop again to moderate and low, providing burn times of 30 and 45 minutes. Visitors and residents are advised to take precautions during high-risk months, especially from April through August, by wearing sunscreen, protective clothing, and limiting sun exposure during peak hours to minimize the risk of skin damage.
