Understanding the UV Index is crucial for residents of Guri, Nigeria to safeguard their skin health and prevent sunburn. With a BSh climate characterized by intense sunlight, Guri experiences significantly high UV levels, particularly from late morning to early afternoon when the index peaks at 11.
