Understanding the UV Index is crucial for the residents of Ipetumodu, Nigeria, especially given its Aw climate zone, which brings ample sunshine year-round. Monitoring UV levels is essential for preventing sunburn and maintaining long-term skin health, as exposure can significantly increase the risk of skin damage and related conditions.

After this apex, the UVI starts to decline, dropping to 10 at 14:00 and gradually easing to 7 by 15:00. Post-peak hours see a further retreat, resting at 4 at 16:00, cooling off to 2 by 17:00, before settling back to 1 at 18:00 and finally fading to 0 after sunset at 19:00.
