Understanding the UV Index is vital for residents and visitors of As Sars, Tunisia, where the Mediterranean climate presents unique sun exposure risks. With UV levels peaking at 12 around noon, awareness of these fluctuations can significantly contribute to sunburn prevention and skin health. Whether you’re relaxing by the coast or exploring the vibrant local culture, being informed about the UV Index helps protect your skin from harmful rays and ensures you enjoy all that this beautiful region has to offer while staying safe under the sun.
The UV Index tells the story of a sunny day with fluctuating intensity. Starting at 07:00, the index is a modest 2, gradually increasing to 3 by 08:00. As the sun climbs higher, we see a significant jump; at 09:00, it leaps to 6, and by 10:00, it reaches 8. The peak of the day occurs at 12:00, boasting a high of 12—a reminder to protect your skin. It slightly tapers off to 11 by 13:00, then 10 at 14:00, as the day begins to wind down. By 15:00, the index drops to 7, and continues to descend, closing out the evening at a gentle 2 by 17:00, with the sun setting further into the evening at 1 for both 18:00 and 19:00. Stay safe under the sun, especially during those midday hours!

Seasonal changes in UV exposure reveal significant variations throughout the year. From March to August, the UV Index peaks, with April to June marking the highest levels of risk. Specifically, May and June experience an extreme UV Index of 10 and 12, where the potential burn time is just 10 minutes. Consequently, March and October present high risks with UV Index values of 7, and residents and visitors should take precautions during these months as well. To protect yourself, it’s advisable to wear sunscreen, protective clothing, and seek shade, particularly during peak hours between 10 a.m. and 4 p.m. From December to February, UV exposure decreases significantly, but individuals should remain vigilant, as moderate levels can still cause skin damage with unprotected exposure.
