In El Ksour, Tunisia, understanding the UV Index is crucial for safeguarding your skin from harmful sun exposure. With the region's Mediterranean climate and its tendency for high UV levels—peaking at 11 during midday—awareness of these fluctuations can significantly help in preventing sunburn and promoting long-term skin health. As the sun rises, UV exposure increases rapidly, making it essential for residents and visitors alike to stay informed. By checking the UV Index regularly, you can enjoy the beautiful sunny days of El Ksour while ensuring you take the necessary precautions to protect your skin.
At sunrise, the UV Index begins to rise slowly, peaking at 1 by 07:00 before climbing steadily throughout the morning. By 09:00, it reaches a moderate 5, but the real intensity kicks in as the sun approaches its zenith. 10:00 marks a significant jump to 8, followed closely by an impressive peak of 11 at 12:00 and 13:00, indicating a high risk for unprotected skin. As the afternoon progresses, the index drops to 9 by 14:00, then gradually declines to 7 at 15:00, before tapering back to a safer 5 by 16:00. As the day winds down, the UV levels return to 2 at 17:00 and finally settle at 1 by 19:00, reminding us that while midday sun offers the most intense rays, protective measures are vital throughout the day.
