From April to September, the UV Index reaches very high to extreme levels, particularly peaking in June at an Index of 11, where the burn time drops to just 10 minutes. Consequently, visitors and residents should be particularly vigilant during this period, especially in May through August, where the burn time remains critical at 15 minutes for high UV levels.
