With UV levels peaking significantly during midday hours, being aware of this forecast not only aids in preventing sunburn but also plays a vital role in maintaining long-term skin health.

High-risk months for sun exposure occur from February to August, where UV Index levels reach very high to extreme values, particularly in April, May, June, and July, with indexes of 11 to 12 and a burn time as short as 10 minutes. Residents and visitors should exercise caution during these months by seeking shade, wearing protective clothing, and applying sunscreen frequently. As we transition into fall and winter, UV levels gradually decrease, with November and December presenting lower risk (UV Index of 6 and 5, respectively), allowing for slightly longer burn times of 25 to 30 minutes.
