In Uyo, Nigeria, staying informed about the UV Index is crucial for maintaining optimal skin health and preventing sunburn. The city's tropical climate, characterized by high temperatures and significant sunlight exposure, amplifies the risk of harmful UV radiation.

The midday sun takes its toll, as the index spikes to 9 by 11:00 AM.
