In El Morro, Mexico, staying informed about the UV Index is crucial for protecting your skin and overall health. With its BWh climate, this picturesque coastal town experiences high levels of ultraviolet radiation, especially during the midday hours when UV Index peaks at a potentially dangerous 12. Understanding these levels is essential not only for preventing painful sunburns but also for reducing the long-term risks of skin damage and other health issues related to sun exposure. Whether you're soaking up the sun or enjoying outdoor activities, being aware of the UV Index can help you make informed choices for a safe and enjoyable experience under the Mexican sun.
The UV Index dramatically rises as the day progresses, peaking in the early afternoon. Starting at a modest 1 at 07:00, the UV exposure quickly increases, reaching 10 by 11:00 and peaking at a dangerous 12 from 12:00 to 13:00. As the sun begins to set, the index gradually declines, falling to 5 by 16:00, and tapering off to a low 1 by 18:00 and 19:00. This ebb and flow underscores the importance of sun safety, especially during those peak hours when the UV Index is at its highest. Stay protected!
