Understanding the UV Index in Casablanca, Morocco, is crucial for protecting your skin and overall health. High UV levels can lead to sunburn and long-term skin damage, making it essential to stay informed about daily UV exposure. With Casablanca's Mediterranean climate, characterized by plenty of sunshine, UV levels can soar as high as 10 during midday, presenting significant risks if proper precautions aren’t taken. By being aware of the UV Index, you can enjoy the beautiful Moroccan sun while keeping your skin safe and healthy.
The UV Index (UVI) follows a distinct pattern throughout the day, starting from a low of 1 at 07:00 and 08:00. As the sun rises higher, the intensity increases, reaching 2 by 09:00. The real surge occurs between 10:00 and 13:00, where it climbs sharply to its peak of 10 at 13:00 and 14:00, indicating extremely high levels of UV radiation. As the afternoon wanes, the index gradually decreases, dropping to 4 by 17:00, then settling back to a comfortable 1 by 19:00. For those enjoying outdoor activities, it’s crucial to take precautions between 11:00 and 15:00 when the UVI is at its highest.
