As the seasons change, so does the UV Index, reflecting the varying intensity of ultraviolet radiation throughout the year. January and December experience moderate UV levels, with burn times of 30 minutes, while February sees an increase to high levels, prompting reduced exposure of just 25 minutes. The high-risk months are from March to August, where the UV Index peaks at 11 during June and July, classifying these months as having extreme exposure risk and requiring careful management of sun exposure, with a burn time of only 10 minutes. Visitors and residents should ideally plan outdoor activities for early mornings or late afternoons, seek shade during peak sun hours, and use sun protection, such as broad-spectrum sunscreen, hats, and sunglasses, particularly during March through August when burn times are significantly shorter. As fall and winter approach, the UV index gradually decreases, making outdoor time less risky, but caution is still advised during the transitional months.
