Understanding the UV Index is crucial for residents of Nyamira, Kenya, where the sun's powerful rays pose daily risks to skin health and overall well-being. With peak UV levels reaching a staggering 11 around midday, it is essential to be aware of potential sunburn and long-term skin damage when spending time outdoors. Nyamira’s subtropical climate means consistent exposure to sunlight, especially during the dry seasons, making it vital to stay informed about UV levels and take protective measures. Whether it's a leisurely afternoon in the sun or weekend activities, knowing the UV Index can help ensure you enjoy the beautiful weather safely and responsibly.

The real intensity arrives by 10:00, where the index spikes to a striking 7, reaching its peak at 12:00 and 13:00 with a blistering 11. This midday sun demands your attention—be sun-safe! As the afternoon progresses, the UV Index gradually declines to 9 at 14:00, followed by a steady decrease to 6 at 15:00 and tapering off to 2 by 17:00. Finally, the UV rays retreat to a 1 by 18:00, disappearing altogether by 19:00. Always stay informed and protect your skin during peak hours!
