The UV Index exhibits significant seasonal variations, with the highest levels recorded during the late spring and summer months. From March to August, the UV Index reaches a peak of 9, indicating a very high risk of harm from unprotected sun exposure, particularly in May through July. Notably, May to August are considered high-risk months for sunburn, with a rapid burn time of just 15 minutes in most cases. In contrast, the UV Index is at its lowest in December (UV Index 1) and January (UV Index 2), where the exposure category is low and the burn time extends up to 45 minutes. Visitors and residents are advised to take precautions during the high UV season—such as using sunscreen, wearing protective clothing, and seeking shade—especially during the peak sun hours around noon. As the UV Index decreases in the fall and winter, vigilance remains important for skin protection on sunny days.
