The UV Index experiences significant variability throughout the year, with the highest levels recorded between January and April, reaching an extreme rating of 19 (with a burn time of just 10 minutes) in both January and December. March and April also maintain extremely high UV levels, with indices of 16 and 13, respectively.

Visitors and residents should be vigilant, particularly from January to April and again in the fall months, ensuring they protect their skin by wearing appropriate sunscreen, protective clothing, and seeking shade during peak sunlight hours to prevent harmful UV exposure.
