In Ad Dann, Yemen, awareness of the UV Index is crucial for maintaining skin health and preventing sunburn. Understanding UV levels helps residents and visitors alike to take necessary precautions against harmful rays, especially during the peak hours of sunlight from 10 AM to 2 PM when the UV Index surges to a maximum of 10. With Ad Dann's arid climate typical of the BWh zone, the risk of overexposure is heightened, making it essential to stay informed about daily UV fluctuations and protect your skin effectively.
