As the seasons change, so does the UV Index, indicating varying levels of sun exposure risk throughout the year. From January to February, the UV levels are moderate (3-5), allowing for longer safe exposure times of about 30 minutes. However, as we move into March and through summer months, the UV Index soars to high (7) and very high (8-10) levels, particularly from April to August, when the burn time decreases sharply to just 15 minutes. September marks a slight decline in UV intensity but remains very high at 8. In contrast, October through December sees a return to moderate levels, with burn times reverting to 25-30 minutes. Visitors and residents should exercise caution during the high-risk months of April through September, taking protective measures such as wearing sunscreen, hats, and sunglasses, and seeking shade during peak sun hours to minimize skin damage.
