In San Atenogenes (La Villita), Mexico, staying informed about the UV Index is crucial for safeguarding your skin and overall health. Understanding UV levels not only helps prevent painful sunburns but also plays a vital role in reducing long-term skin damage and the risk of skin cancer. With a BSk climate characterized by intense sunlight, particularly during midday, residents and visitors face elevated UV exposure, especially when the index peaks at a staggering 14 from 12:00 PM to 2:00 PM.
