The peak months of May through August maintain a critical UV Index of 9, portraying significant risk with the same short 15-minute burn time.

By November and December, UV levels drop again to moderate and low, providing burn times of 30 and 45 minutes. Visitors and residents are advised to take precautions during high-risk months, especially from April through August, by wearing sunscreen, protective clothing, and limiting sun exposure during peak hours to minimize the risk of skin damage.
