Understanding the UV Index in Los Guerra, Mexico, is essential for safeguarding your skin and overall health against harmful UV rays. With a climate characterized by hot and dry conditions, the risk of sunburn and long-term skin damage rises, particularly during peak hours. Notably, UV levels can reach a maximum of 12 from noon to 2 PM, indicating a very high risk of harm from unprotected sun exposure. By being aware of these levels, you can take proactive measures to enjoy the beautiful weather while protecting yourself from the sun's intense rays.
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!
