Understanding the UV Index is crucial for residents and visitors in Tetouan, Morocco, where the sun shines brightly in a Mediterranean climate characterized by hot, dry summers. Knowing the UV levels not only helps in preventing painful sunburn but also plays a vital role in maintaining long-term skin health. During peak hours, particularly from 11 AM to 2 PM, Tetouan experiences intense UV radiation, reaching a maximum index of 11. This awareness enables individuals to take appropriate precautions, ensuring safe enjoyment of the outdoors while minimizing the risks associated with excessive sun exposure.
During the day, the UV Index exhibits a striking pattern as it peaks in the late morning and early afternoon. Starting from a modest value of 1 at 07:00, the index gradually climbs, reaching 3 by 09:00. Expect a sharp increase around 10:00, when it soars to 5, and it doesn't stop there; by noon, it hits an impressive 10. The highest point of the day occurs at 13:00, with a peak of 11, indicating a critical time for sun exposure. As the afternoon progresses, the index begins to decline, falling to 10 at 14:00 and tapering off to 9 at 15:00. By evening, the UV Index diminishes steadily, finishing the day back at 1 by 19:00. This data emphasizes the importance of protective measures during the high noon hours when UV levels are at their most intense.
