From January to February, UV exposure is relatively low (UV Index 2-4), allowing for about 45 minutes of safe sun exposure, yet caution should still be exercised. March and April ramp up to high levels (UV Index 6-7), with burn times decreasing to 25 minutes. The summer months of May through August present the highest risk, as UV Index values hit 9-10, indicating very high exposure with a mere 15 minutes burn time—adequate sun protection is essential during this period. As autumn arrives, UV levels begin to drop; September returns to high (UV Index 7) with 25 minutes of burn time, followed by moderate levels in October (UV Index 5) and November (UV Index 3), allowing for 30 minutes of exposure before winter brings low levels once again in December (UV Index 2) with 45 minutes of safe sun time.
