As the seasons change, so does the UV Index, impacting sun exposure and skin safety. January and December see a low UV Index of 2, allowing for safer outdoor activities with a burn time of 45 minutes. However, as we progress into February, the UV Index rises to 4 (moderate), with a burn time reduced to 30 minutes. The risk escalates sharply from March to April, where the UV Index reaches 6 (high) and 8 (very high), respectively, demanding more vigilant sun protection. The peak months of May through August experience extreme UV levels of 10 and 9, requiring minimized sun exposure with a mere 15 minutes burn time. After August, the risk gradually decreases, with September at 7 (high) and October at 5 (moderate). During the fall and winter months, residents and visitors should remain cautious but can enjoy the sun safely with proper precautions, especially during high-risk months of April through August. Always apply sunscreen, wear protective clothing, and seek shade during peak hours to minimize UV exposure.
