Understanding the UV Index is crucial for residents and visitors in Jiblah, Yemen, where the bright sunshine can lead to significant UV exposure. With high levels reaching up to 13 around midday, being aware of UV levels is essential for preventing sunburn and protecting your skin health. In this arid climate, typical of the BWh zone, the sun's intense rays pose increased risks, especially during the peak hours of 10 AM to 2 PM. By staying informed about the UV Index, you can take the necessary precautions and enjoy the beautiful outdoors while safeguarding your well-being.
