As the seasons change, so do UV levels, significantly influencing the risk of sunburn and skin damage. January and December exhibit moderate UV indices of 4, allowing up to 30 minutes of safe exposure. February marks an increase to a high level of 6, reducing safe exposure to 25 minutes. This upward trend peaks in the spring and early summer, with May and June reaching an extreme UV index of 11 and 12, allowing only 10 minutes of exposure. March and April also present very high risks with indices of 8 and 9, advising extreme caution during these months. High-risk months, particularly March to August, require visitors and residents to take preventative measures, such as wearing sunscreen, protective clothing, and seeking shade during peak hours, especially when the index exceeds 8. As we move into fall, the UV index gradually declines, but remaining vigilant is still wise until November.
