Understanding the UV Index is crucial for residents of Ifon, Nigeria, as it plays a vital role in safeguarding skin health and preventing sunburns. With elevated UV levels peaking at 12 during the midday hours, awareness of these changes can help you take appropriate protective measures. Ifon’s Aw climate zone brings not only warmth but also significant UV exposure risks, especially when the sun is at its highest. By being informed about the daily UV Index, you can better plan your outdoor activities and ensure your skin remains healthy and protected from the sun's harmful effects.
As the sun rises, the UVI begins its climb, with a mild 1 at 07:00. By 08:00, it gently increases to 2, making early morning outings quite pleasant. The intensity ramps up quickly, hitting 4 at 09:00 and then surging to 6 by 10:00. The true peak arrives during midday, as the index soars to a blistering 12 between 12:00 and 13:00, signaling a prime time for sun protection. 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. Monitor the UVI closely to ensure safe sun exposure throughout the day!

Throughout the year, UV index levels exhibit significant seasonal variation, with the highest risks typically occurring from February to October.
