Throughout the year, the UV Index reflects significant seasonal changes, indicating varying levels of sun exposure risk. January and December have the lowest UV levels (Index 2, low exposure), allowing for 45 minutes of safe sun exposure. As spring approaches, February (Index 3, moderate) heightens the risk slightly, leading to a burn time of 30 minutes. The high-risk months emerge in late spring and summer: March (Index 6), April (Index 7), May (Index 8), and especially July (Index 11, extreme), which dramatically reduces safe exposure time to just 10 minutes. In August and September, UV levels remain very high (Index 9-10), necessitating caution during outdoor activities. Come October, the risk decreases to high (Index 6), while November and December return to low exposure levels. Visitors and residents should take necessary precautions during the high-risk months, particularly from May through July, including using sunscreen, wearing protective clothing, and seeking shade during peak sun hours to minimize the risk of UV-related harm.
