Understanding the UV Index is crucial for residents of Umuneke-Ngor, Nigeria, where the climate, characterized by high temperatures and ample sunshine, poses significant UV exposure risks. Awareness of UV levels not only helps in preventing sunburns but also plays a vital role in maintaining skin health over time. With peak UV Index readings reaching as high as 11 around midday, it's essential for locals to be educated about these levels to protect themselves effectively against harmful effects. As the sun rises and shines brightly in this vibrant region, being informed is the first step towards enjoying the outdoors safely.
The UV Index throughout the day showcases a dramatic increase in intensity, reaching its peak at 12:00 PM and 1:00 PM with a scorching 11. Early morning sees a mild start, with readings of 1 at 7:00 AM and climbing to 2 by 8:00 AM. As the day progresses, the index escalates, hitting 4 by 9:00 AM and a notable 7 at 10:00 AM. The midday sun takes its toll, as the index spikes to 9 by 11:00 AM. Following this, it stabilizes at its zenith of 11 before beginning its descent—dropping to 9 at 2:00 PM and then tapering down to 6 by 3:00 PM. The evening offers a welcome relief with levels declining to 2 at 5:00 PM, and ultimately sinking to 0 by 7:00 PM. This hourly data clearly illustrates the importance of sun protection during peak UV hours, especially from 11 AM to 1 PM when the sun is at its strongest.
