The UV Index experiences significant fluctuations throughout the year, with the highest levels recorded between January and April, where the index consistently reaches a severe 15 and falls into the "extreme" exposure category, demanding caution for outdoor activities as minimal sun exposure can result in burns in just 10 minutes. As the year progresses into May and June, the index reduces to 9 and 7, respectively, transitioning to "very high" and "high" levels, which still require mindful sun protection with burn times extending to 15 and 25 minutes. However, the risk escalates again in the months of September and October with indices of 12 and 13, reverting to an "extreme" exposure category. Throughout the winter months, November and December also maintain a hazardous UV Index of 15. Given these conditions, it is advised that both visitors and residents practice diligent sun safety measures—applying broad-spectrum sunscreen, wearing protective clothing, and seeking shade during peak hours, especially from January to April and September to December to minimize the risk of sun-related health issues.
