Throughout the year, UV levels exhibit significant seasonal variability, with the highest risks occurring during the winter and late fall months. January and December both record an extreme UV Index of 14, with a burn time of just 10 minutes, making these months particularly hazardous for sun exposure. February follows closely with a UV Index of 13. The high-risk months for UV exposure are thus identified as November through March, when UV levels remain consistently extreme to very high (UV Index 10 or above). Residents and visitors should take precautionary measures during these months, such as wearing protective clothing, utilizing sunscreen, and seeking shade, especially during midday hours when sun intensity peaks. As the year progresses into June, July, and August, the UV Index drops to moderate levels, allowing for safer outdoor activities, but still necessitating basic sun safety practices.
