Understanding the UV Index is crucial for residents and visitors in Sidi Yahya Ou Saad, Morocco. As this charming town basks in a Mediterranean climate (Csa), exposure to sunlight can lead to elevated UV levels, especially during midday when the index peaks at a striking 12. Being aware of the UV Index helps you take precautions against sunburn and protects your skin health, ensuring you enjoy the beautiful Moroccan outdoors without harm. With such intense midday sun, it's vital to stay informed about UV levels to safeguard your health while exploring this vibrant region.
As the sun rises at 07:00, the UV Index starts off gently at 1, perfect for those early morning strolls. By 08:00, it nudges up to 2, inviting more outdoor activity. The real action begins around 09:00, when the index hits 3, signaling it's a great time for some light exercise. But things heat up quickly: by 10:00, the UV Index reaches 6, and from 11:00 to 13:00, it skyrockets to a blistering 9 and then 11, peaking at 12 in the afternoon—the ideal time to seek shade or sunscreen up! The intensity begins to wane after 14:00, as it gradually dips to 10 at 15:00, before further easing to 5 at 17:00. By evening, the UV Index returns to a tranquil 2 by 18:00 and finally settles back at 1 by 19:00. It’s a day that reminds us to take sun safety seriously while enjoying the radiant daylight!
