Throughout the year, the UV Index experiences notable changes, peaking during the summer months. From March to August, UV levels rise significantly, with April to July marking the highest-risk months, exhibiting extreme levels of UV exposure (Index 11-12) and requiring only 10 minutes of unprotected sun exposure before risking skin burn. As a result, it's crucial for visitors and residents to take protective measures during these months, such as wearing sunscreen, protective clothing, and seeking shade during peak sunlight hours. Conversely, the winter months (January, November, December) present moderate UV levels (Index 4-5) and have longer burn times of 30 minutes, still warranting some level of sun protection but with less urgency. Overall, increased awareness and protective practices are essential, especially from March to August, to mitigate the risk of harmful UV exposure.
