In Ciudad Miguel Alemán, Mexico, being mindful of the UV Index is crucial for protecting your skin from harmful solar radiation. Understanding UV levels helps in preventing sunburns and reducing the long-term risks of skin conditions. With a climate classified as BSh, residents and visitors experience significant UV exposure, especially during peak hours—where the Index reaches a maximum of 12 from 1 PM to 3 PM. By staying informed about these daily fluctuations, you can enjoy the sunny days while safeguarding your skin's health.
Today’s UV Index varies dramatically throughout the day, beginning at a mild 1 from 7:00 AM to 9:00 AM, making it a safe time for outdoor activities with minimal sun protection. As the sun climbs higher, the index rises to a moderate 4 by 10:00 AM and then escalates sharply, peaking at a blistering 12 between 1:00 PM and 2:00 PM. It's crucial to take precautions during this time, such as wearing sunscreen, hats, and sunglasses. Following the peak, the intensity diminishes gradually, dropping to 5 by 5:00 PM and settling back to 1 as evening approaches at 7:00 PM. Be mindful of the sun’s potency; it’s wise to seek shade or limit direct exposure during peak hours!
