The UV Index experiences significant variability throughout the year, with January and February marking the beginning of a gradual rise, where levels reach a very high category. The risk intensifies dramatically from March to August, where the index peaks at 16 in July, indicating an extreme exposure category and a critical burn time of just 10 minutes. As summer transitions to early fall, September and October still maintain extreme levels, gradually decreasing but remaining a risk for sunburn. High-risk months, particularly from March to October, require visitors and residents to take proactive measures such as wearing protective clothing, applying sunscreen frequently, and seeking shade during peak hours to mitigate the increased likelihood of skin damage. In contrast, November and December see a return to very high and high exposure levels, respectively, with longer burn times, but still warrant caution. Overall, anyone spending time outdoors should be vigilant, particularly during the summer months when UV levels are at their highest.
