In Derdara, Morocco, being aware of the UV Index is crucial for safeguarding your skin against harmful ultraviolet rays. Understanding UV levels can help you take proactive measures to prevent sunburn and bolster skin health, particularly in a region characterized by a Csa climate that experiences intense sunshine. During peak hours, typically between 11:00 AM and 2:00 PM, the UV Index can soar to a maximum of 11, indicating a very high risk of harm from unprotected sun exposure. By staying informed about the UV index, residents and visitors alike can enjoy the beautiful Moroccan sun while keeping their skin protected.
As the sun rises, the UV Index begins at a mild 1 at 07:00, perfect for those early morning strolls. By 08:00, it climbs to 3, still manageable for outdoor activities. The intensity increases significantly by 10:00, racing to 7, and peaks at a striking 11 by 13:00. This midday surge, reaching 10 at 12:00 and tapering to 9 at 15:00, calls for careful sun protection. As the afternoon wanes, the UV Index descends gracefully to 2 by 18:00, and finally settles back at 1 by 19:00, making for a pleasant evening. Remember, when the sun is highest, it’s vital to stay protected!
