Throughout the year, seasonal UV changes present varying risks for sun exposure, with the highest UV Index recorded during the winter months. From January to March, the UV Index remains at an extreme level (15–13) with a critical burn time of just 10 minutes, making this period particularly hazardous for unprotected skin. As the year progresses, April sees a decrease to a very high category (UV Index 10, burn time 15 min), followed by a moderate level in June (UV Index 5, burn time 30 min). However, the risk escalates again in late summer and early fall, with August and September reaching very high levels of UV exposure once more. The final months of the year return to extreme conditions (UV Index 14), emphasizing the importance of sun protection year-round.
