The UV Index varies significantly throughout the year, with high-risk months primarily occurring from March to September. During this period, the UV Index reaches its peak at 11 in both May and June, categorizing exposure as extreme and reducing the safe burn time to just 10 minutes. Care should be taken particularly in April, when the Index climbs to 8 (very high) and in July and August, both remaining in the very high range at 10 and 9, respectively. Visitors and residents are advised to use adequate sun protection, including sunscreen, hats, and protective clothing, particularly during these months when the risk of skin damage is greatest. Conversely, the UV Index drops to moderate levels in January, February, November, and December, allowing for longer safe exposure times of 30 minutes. However, vigilance is still recommended to maintain skin health year-round.
