As the year progresses, the UV Index experiences significant fluctuations, peaking during the summer months. From January to March, the UV levels rise gradually, moving from a moderate index of 5 to a very high 8. This trend continues through April and May, where monthly indexes remain very high at 10 and 9 respectively. The months of June, July, and August are the most critical, with UV levels soaring to extreme indexes of 11 and 13, necessitating quick action, as burn times shorten to just 10 minutes. The fall season ushers in a decline, yet September and October still exhibit extreme to very high levels, with a burn time of 10 to 15 minutes. As a result, both visitors and residents should exercise increased caution during the high-risk months of March to October, prioritizing sun protection measures such as sunscreen, hats, and protective clothing to minimize the risk of skin damage.
