Understanding the UV Index is crucial for residents and visitors in El Sasub, Mexico, where the warm, tropical climate often elevates sun exposure risks. As the UV Index can reach a maximum of 13 during midday, awareness of UV levels is essential for preventing sunburn and maintaining long-term skin health. With peak values occurring between 11 AM and 2 PM, when the sun is at its highest, being knowledgeable about these levels allows you to take proactive measures to shield yourself from harmful rays and enjoy the beautiful sunny days that El Sasub has to offer.
At 07:00 and 08:00, the UV Index remains low, peaking at 1, making it a safe time for outdoor activities. However, as the day progresses, the sun’s intensity ramps up sharply. By 10:00, the index reaches 5, climbing to a striking 11 by noon. The day hits its peak at 13:00 and 14:00, with a UV Index of 13, warranting caution and sun protection. As the afternoon unfolds, you’ll find a gradual decline: readings drop to 11 at 15:00, then 8 at 16:00, further easing to 2 by 18:00, and finally settling back to 1 by 19:00. Remember, to enjoy the sun safely, consider protective measures during the high UV hours!
