In Yelwa, Nigeria, awareness of the UV Index is crucial for safeguarding your skin against harmful ultraviolet radiation. Understanding UV levels can help residents and visitors alike prevent sunburn and promote long-term skin health, especially in a region known for its Aw climate—characterized by hot and sunny weather. With peak UV levels soaring to 11 during midday, it's essential to stay informed about your exposure risks throughout the day.

The peak occurs between 12:00 PM and 1:00 PM, when the index hits a scorching 11, indicating a very high risk of harm from unprotected sun exposure. After this peak, the index steadily declines; by 3:00 PM, it drops to a safer 7, and by 5:00 PM, it further falls to 2. As the sun sets, the UV intensity diminishes to 1 at 6:00 PM and finally drops to 0 by 7:00 PM, making evening outings much safer. Be sun-smart during the peak hours to protect your skin!
