As the seasons change, so does the UV Index, which significantly impacts sun exposure risks. January and February present a moderate risk with a UV Index of 5, allowing for a burn time of 30 minutes. However, from March to August, the UV Index spikes, reaching an extreme level of 11 during the summer months, where a mere 10 minutes of exposure can lead to burns. This makes March to August the high-risk period, especially in April and May when the index reaches its peak. September and October maintain a very high level at 10 and 8, respectively, with shorter burn times of 15 minutes. November sees a shift to a high risk with a UV Index of 6, and December eases to a moderate risk. Residents and visitors are advised to take precautions during the high-risk months by using sunscreen, wearing protective clothing, and seeking shade to minimize UV exposure and potential skin damage.
