The UV Index experiences significant seasonal fluctuations, with the highest values observed from March through October. During these months, particularly from May to August, the UV Index peaks at 13 to 14, indicating an extreme exposure category, with a burn time as short as 10 minutes. The high-risk months are therefore identified as March to August, where spending too much time in direct sunlight without protection can lead to severe skin damage. In contrast, the risk decreases in January and February (UV Index of 8 to 10, very high) and again in November and December, where lower UV levels (especially in December at 7) allow for longer safe exposure times (up to 25 minutes). Visitors and residents should take protective measures such as wearing sunscreen, hats, and protective clothing during peak months, and seek shade whenever possible to minimize the risk of UV exposure.
