The UV Index exhibits significant seasonal variations, with the highest levels recorded during the winter months. January, February, and March feature extreme UV exposure, with indices peaking at 15 in January and maintaining a burn time of just 10 minutes, indicating a high risk for skin damage. As we transition into April, the index drops to 7 (high exposure), leading to a longer burn time of 25 minutes. From May to July, the index remains moderate, stabilizing between 4 and 5, which corresponds to burn times of 30 minutes, offering slightly less risk. However, the end of summer signals a return to higher exposure with August (UV Index 6), followed by September (8), prompting a need for caution as burn times decrease notably to 15 minutes. The cycle finishes with extreme levels returning in October, November, and December, where the UV Index again climbs to 12-14 and burn times tighten to 10 minutes. Visitors and residents are advised to take precautions during high-risk months—specifically from January to March and again in October and November—by wearing protective clothing and using broad-spectrum sunscreen to minimize the risk of skin damage.
