Understanding UV levels can help you prevent sunburn and reduce the risk of long-term skin damage, especially during the peak hours of sun exposure.

Low-risk months are observed in January, December, and to some extent, November with indexes of 2 to 3, allowing for longer burn times of 30 to 45 minutes. The risk then rises substantially starting in February, peaks during the summer months of May through August with very high ratings between 8 and 10—advising visitors and residents to minimize exposure to just 15 minutes during these months. March and April also present high UV levels, emphasizing the need for protective measures.
