Understanding the UV Index in Oursi, Burkina Faso, is crucial for everyone who wants to enjoy the sun safely. With UV levels reaching a striking 12 at midday, awareness of these levels is vital in preventing sunburn and maintaining skin health. Oursi's hot semi-arid climate means that UV radiation can be particularly intense, especially between 10 AM and 2 PM, when the risk of skin damage is greatest. By staying informed about the UV Index, residents and visitors can better protect themselves from harmful effects, ensuring a healthier outdoor experience under the Burkinabé sun.
The UV Index throughout the day presents a dramatic curve of sun intensity, peaking spectacularly at 12 during the midday hours. Starting at a mild 1 at 07:00, the index climbs steadily, reaching 3 by 08:00. As the sun rises higher, the intensity escalates, hitting 6 at 09:00 and soaring to 8 by 10:00. The pinnacle of UV exposure occurs between 11:00 and 13:00, with an impressive high of 11 at 11:00 and 12 at noon. Following this zenith, the numbers gracefully dip to 8 at 14:00, then gradually taper off, descending to 5 by 15:00 and further down to 1 by 17:00. As the evening approaches, the UV Index turns gentle, resting at 0 by 19:00, signaling the end of a sun-soaked day. Always remember to protect your skin during those peak hours!
