As the seasons change, so does the UV Index, significantly impacting sun exposure and the risk of skin damage. From January to February, the UV Index is moderate (3-4) with a longer burn time of 30 minutes. However, as we transition into March and April, the UV Index rises sharply to high (7) and very high (8) respectively, with burn times decreasing to just 25 and 15 minutes. The peak UV intensity occurs during the summer months of July and August when the Index reaches an extreme level of 11, with a mere 10 minutes for potential sunburn. Visitors and residents should be particularly cautious from March through September, the high-risk months for UV exposure, and take proactive measures such as applying sunscreen, wearing protective clothing, and seeking shade during peak hours to minimize skin damage. As the year concludes, the UV levels drop again in October to moderate levels in November and December, providing a respite from intense sun exposure.
