In Mang GJen, Vietnam, understanding the UV Index is crucial for your skin health and overall well-being. With its Cwa climate, this region experiences significant solar exposure, particularly around noon when the UV index peaks at an alarming 14. Being aware of UV levels is essential not only for preventing sunburn but also for reducing the long-term risks associated with skin damage and skin cancer. As the sun rises, UV levels fluctuate drastically, reaching moderate levels as early as 9:00 AM and soaring to dangerous heights by 11:00 AM. Stay informed to protect yourself and enjoy the beautiful outdoors safely!
The UV Index throughout the day exhibits a clear peak in the late morning, with values surging to a maximum of 14 at both 11:00 and 12:00.
