Throughout the year, UV Index levels exhibit significant seasonal fluctuations, impacting the risk of overexposure to sunlight. January and February maintain a low UV Index of 2, allowing for a safe burn time of 45 minutes. However, as we transition into March, the UV Index rises to 4 (moderate), shortening the safe burn time to 30 minutes. The real risk begins in April and peaks from May to July, where the UV Index reaches 8 (very high), necessitating precautionary measures with a mere 15 minutes of safe sun exposure. While August and September still present high levels (UV Index of 7 and 6 respectively), burn times increase slightly to 25 minutes. As autumn sets in, October sees a reduction to a moderate UV Index of 4 again, before declining to 2 and 1 in the final months of the year (November and December), where sun exposure is considered low risk. Visitors and residents should remain vigilant from April through September, employing sunscreen, protective clothing, and seeking shade during peak sunlight hours, especially on high-risk months when the UV Index exceeds 6.
