Understanding the UV Index in Aslam, Yemen, is crucial for safeguarding your skin and overall health. With an arid climate that typically presents elevated UV levels, being aware of sun exposure is vital to prevent sunburn and long-term skin damage. The UV Index varies throughout the day, reaching a peak of 10 around noon, which indicates a very high risk of harm from unprotected sun exposure. By staying informed about these UV levels, you can take appropriate precautions, ensuring your time outdoors remains enjoyable and safe.
As the sun rises, the UV Index begins its ascent, peaking at a robust 10 between 11:00 and 12:00. This is the point when sun safety is crucial, as the intensity of ultraviolet radiation can cause harm to unprotected skin in just minutes. The morning starts with a low reading of 1 at 07:00, and steadily climbs to 3 by 08:00, before reaching a moderate 5 at 09:00. By 10:00, the index surges to 8, signaling that it's time to seek shade or apply sunscreen. In the afternoon, it gradually declines from 9 at 13:00 to 4 at 15:00, and continues to drop to a mere 1 by the evening, making those twilight hours notably safer for outdoor activities. As the day wraps up around 19:00, a calm 0 confirms that the UV threat has vanished, leaving the sky clear for stargazing. Stay informed and protect your skin during peak hours!
