Understanding seasonal changes in UV Index is essential for both visitors and residents. During the winter months (January, February, November, December), the UV Index remains low (1-2), allowing for a longer safe exposure time of up to 45 minutes without risk of burning. As spring approaches, UV levels begin to rise, with March reaching a moderate index of 4, decreasing safe exposure time to 30 minutes. The summer months of June and July present the highest risk, with UV Index values soaring to 7 and 8, where exposure times can be as short as 15 minutes, classified as very high risk. Thus, it is crucial to take protective measures, especially from April through August, when the UV Index is consistently high or very high, prompting recommendations for sunscreen, protective clothing, and seeking shade during peak hours. In September and October, the risk decreases to moderate levels, returning to safer conditions as winter approaches. Visitors and residents alike should remain vigilant and adjust their sun safety practices according to these seasonal changes.
