As the seasons change, so too does the UV Index, highlighting the importance of sun protection for both residents and visitors. During the winter months (January to February), the UV Index remains low to moderate, with burn times ranging from 30 to 45 minutes. However, as spring approaches, particularly in March and April, the UV Index begins to rise, reaching a high of 6 in April, which necessitates increased caution. The summer season (May to August) marks a significant peak in UV exposure, with indices soaring to very high levels of 8 to 9, resulting in quick burn times of just 15 minutes—this is the high-risk period for sunburn and skin damage. As summer transitions into fall (September to October), the UV Index gradually decreases but still remains in the moderate to high categories, with burn times between 25 to 30 minutes. To protect yourself, it is advisable to seek shade, wear protective clothing, and use sunscreen, particularly from May through August when UV levels are at their most intense.
