Throughout the year, UV Index levels remain notably high, particularly during the peak months from March to May, where the index reaches an extreme level of 15 in April, classified as high-risk for sun exposure, and a burn time of just 10 minutes. Residents and visitors should be especially vigilant during these months, as consistent exposure can lead to severe skin damage. The summer months (June to August) also maintain high UV levels, though they slightly decrease, averaging 12 to 13 on the UV Index. Even in the transition to fall, from September to November, the levels stay consistently high. Only in December does the UV Index drop to 10 (very high), allowing for a marginally longer burn time of 15 minutes. Therefore, it is crucial for everyone to use effective sun protection measures—including sunscreen, protective clothing, and shade—year-round to minimize the risks of UV-related health issues.
