Throughout the year, UV Index levels vary significantly, peaking during the summer months. January starts with a high UV Index of 6, with a burn time of 25 minutes, but by February and March, it escalates to 8 and 9, respectively, both categorized as very high, and reducing burn time to 15 minutes. As we transition into April and May, the UV Index hits an extreme level of 12, where the burn time shortens to just 10 minutes. This extreme level continues through July and August, maintaining a UV Index of 13. September sees a slight decline to 11 but remains in the extreme category, while October returns to very high at 10. November and December finally give a reprieve with lower indices of 7 and 5, respectively. Therefore, the high-risk months for sun exposure are from April to September, where the UV Index is at its highest, urging visitors and residents to take protective measures, such as wearing sunscreen, sunglasses, and protective clothing, and limiting sun exposure during peak hours for safety.
