From March to August, the UV Index escalates significantly, reaching its highest point of 11 in August, categorizing it as extreme risk with a burn time of just 10 minutes. April to July are considered high-risk months, as they display very high UV levels, necessitating increased sun protection measures. Visitors and residents are strongly advised to apply broad-spectrum sunscreen, wear protective clothing, and seek shade, especially during peak sun hours. As autumn approaches, UV levels gradually decrease, returning to moderate by November, making sun protection less crucial but still advisable during sunny days.
