Throughout the year, the UV Index fluctuates significantly, indicating varying levels of risk for sun exposure. From January to February, UV levels remain in the moderate range (3-4), allowing for approximately 30 minutes of safe sun exposure. As spring approaches in March, the UV Index escalates to 7, marking the beginning of high risk, with a reduced safe exposure time of 25 minutes. The late spring and summer months, particularly April to August, experience the highest UV readings, with values reaching a peak of 10 in June and July, categorizing them as very high risk and necessitating careful sun protection after just 15 minutes of exposure. September sees a slight decline to an 8, while October drops to a 6, signaling a return to high risk. Conversely, late fall and winter months—November (3) and December (2)—see safer exposure categories, with burn times extending up to 30-45 minutes. Visitors and residents should take proactive measures in high-risk months (March to September) by using sunscreen, wearing protective clothing, and seeking shade to minimize sun damage.
