The UV Index exhibits considerable seasonal variation, peaking in the winter months of January, February, and March, where it reaches extreme levels (16-13), accompanied by a very quick burn time of just 10 minutes. As spring approaches in April, the index decreases slightly to 10 but remains very high, allowing for a burn time of 15 minutes. May and August see a drop to 7, classified as high, with burn times extending to 25 minutes. The summer months of June and July remain moderate at 5, allowing for longer exposure of 30 minutes before risk increases again in September with a very high index of 9 and a shorter burn time of 15 minutes. The trend shifts back to extreme levels in October, November, and December (12-15), demanding careful attention to UV exposure with only 10 minutes before burn onset. Visitors and residents are strongly advised to prioritize sun protection during the high-risk months of January through March and October through November, by wearing sunscreen, protective clothing, and hat, and to seek shade as necessary to minimize the risk of UV-related harm.
