January and February present low UV exposure with an index of 1-2, allowing for safe outdoor activities without much concern, as the burn time extends to 45 minutes. By March, the UV Index rises to 4, indicating moderate exposure; thus, a reduction in burn time to 30 minutes is advised. April to August marks the height of UV intensity, with values peaking at 9 in July, categorizing this period as very high risk for skin damage and shortening burn time to just 15 minutes. Visitors and residents should prioritize sun protection during these months, wearing sunscreen, protective clothing, and seeking shade, particularly in May, June, July, and August. As summer ends, UV levels decrease, returning to moderate in October, and then dropping back to low in November and December, where the burn time increases again to 45 minutes. Overall, being vigilant about sun exposure, particularly from April to August, is key to maintaining skin health.
