Throughout the year, seasonal UV changes exhibit significant fluctuations, particularly peaking during the winter months (January to April) with an extreme UV Index ranging from 11 to 16 and a burn time of just 10 minutes. The high-risk months are notably concentrated in the winter and early spring, where the UV Index remains extreme, suggesting that visitors and residents should take extra precautions by seeking shade and wearing protective clothing. As we transition into late spring and summer, the UV Index decreases to a very high and high level, allowing for slightly longer safe exposure times of 15 to 25 minutes. However, even during these months (May to August), it is crucial to maintain vigilance, especially in September and October, as UV levels rebound to extreme levels again. To stay safe, individuals are advised to consistently check the UV Index and employ sun protection strategies year-round, especially during peak UV times.
