Understanding the UV Index in Banco Nacional, Mexico, is crucial for maintaining skin health and preventing sunburn. With the area’s BWh climate characterized by intense sunlight, awareness of UV levels can significantly reduce risks associated with prolonged sun exposure. During peak hours, such as between 12:00 PM and 3:00 PM, the UV Index soars to levels of 10 and above, indicating a high potential for skin damage. By being informed about these UV levels, residents and visitors can take proactive measures to protect their skin and enjoy the beautiful weather safely.
This hour-by-hour UV Index data reveals a striking pattern throughout the day. Starting off gently at 1 at 07:00 and 08:00, the intensity begins to rise gradually, reaching 2 by 09:00. The sun's rays become increasingly potent as the clock ticks, hitting 4 at 10:00 before skyrocketing to 7 at 11:00. The peak occurs in the early afternoon, with a scorching 10 at 12:00 and reaching an intense 13 at 14:00. Following this zenith, the UV Index begins to taper off, descending to 12 by 15:00, then dropping to 9 at 16:00. As the day cools, the UVI continues to decline, finding itself at 3 by 18:00 and returning to a more manageable 1 at 19:00. In summary, the UV exposure is highest between 11:00 and 14:00, making those hours critical for sun safety.
