Understanding the UV Index is crucial for residents and visitors in Kiryandongo, Uganda, where the sun's intense rays can pose serious health risks. Awareness of UV levels helps in preventing sunburn and protecting skin health, particularly during the peak hours of high exposure. With Kiryandongo's Aw climate, characterized by its warm temperatures and strong sun, knowing when UV radiation reaches dangerous levels—such as the peak index of 11 between noon and 1 PM—can make all the difference in maintaining your well-being while enjoying the outdoors. Stay informed and protect yourself from potential harm!
As the sun rises, the UV Index begins its subtle ascent, starting at a modest 1 at 07:00 and 08:00. By 09:00, it jumps to 3, signaling the start of more intense rays. The real surge occurs between 10:00 and 13:00, where it peaks at an impressive 11, indicating a high risk of harm from unprotected sun exposure. From 14:00, it gradually declines, with values dropping to 10 and then easing further down to 5 by 16:00. As the late afternoon sets in, the index softens to 2 at 17:00 and returns to a safe 1 by 18:00, ultimately falling to 0 by 19:00. This daily dance of UV radiation underscores the importance of sun safety, especially during the midday hours.
