Throughout the year, the UV Index reveals significant seasonal variations, particularly peaking in the winter and late fall months. From January to November, the UV Index consistently reaches extreme levels, often hitting 15, with a burn time as short as 10 minutes in these high-risk months. March and April see slightly lower values (UV index of 14 and 12, respectively), yet still remain in the extreme range. As we transition into May and June, the UV Index drops slightly to levels categorized as very high and high, allowing for somewhat increased burn times. However, July and August shift back to very high ratings, reinforcing the need for vigilance. In September and October, the UV Index once again peaks at extreme levels, with a return to the 10-minute burn time typical of the winter months. November maintains this extreme categorization, rounding out the year with similar risks. Visitors and residents are strongly advised to take precautions by wearing protective clothing, using high-SPF sunscreen, and limiting sun exposure during peak hours, particularly from November to April when the risks are at their highest.
