As the seasons change, so too does the UV Index, which significantly influences sun exposure risk. High-risk months for UV exposure are typically from March to August, during which the UV Index peaks at an extreme level of 11, indicating a burn time as short as 10 minutes. Specifically, April, May, July, and August mark the critical periods for intense sun exposure. As such, it’s vital for both visitors and residents to take proactive measures during these months, including wearing protective clothing, applying broad-spectrum sunscreen, and seeking shade during peak sunlight hours. Conversely, the winter months of December and January see a drop to moderate levels, with safer burn times of 30 minutes, providing an opportunity for outdoor activities with reduced risk. Always stay informed about current UV levels and prioritize sun safety year-round.
