Throughout the year, seasonal variations in the UV Index indicate a significant shift in sun exposure risks. From January to February, UV levels remain in the moderate category, with a burn time of 30 minutes. However, as spring begins in March, the index rises to high, necessitating shorter exposure times of 25 minutes. The most critical months for UV exposure are April through August, where the index peaks at extreme levels of 11 in June and July, offering burn times as brief as 10 minutes. After this peak, UV levels gradually decline but remain very high until September. As temperatures cool into October and beyond, the risk decreases, with November and December reflecting moderate and low exposure risks respectively. Visitors and residents are advised to take precautions, especially during the high-risk months of April, May, June, and July, by seeking shade, wearing protective clothing, and applying sunscreen regularly to mitigate the risks of sunburn and long-term skin damage.
