Throughout the year, the UV Index experiences notable seasonal changes, with high-risk months typically occurring from April to August, when indices reach 10 or higher and burn times decrease significantly. April and May present a very high exposure category with a burn time of just 15 minutes, while the peak of summer in June and July escalates to an extreme category, reducing burn time to a mere 10 minutes. Even August maintains this extreme level before tapering off in September. For visitors and residents, it is crucial during these high-risk months to take precautionary measures such as wearing sunscreen, protective clothing, and seeking shade between 10 a.m. and 4 p.m. to minimize the risk of sunburn and long-term skin damage. In contrast, the fall and winter months offer more moderate UV levels, particularly from November to February, with indices dropping back to a high or moderate exposure category and increasing burn times to 25 minutes or longer.
