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.
