In Estancia de San Antonio, understanding the UV Index is essential for protecting your skin and overall health under the sun's intense rays. With a climate classified as BSh, the region experiences high UV levels, particularly between late morning and early afternoon when the index peaks at a scorching 14. This awareness is vital for sunburn prevention and maintaining long-term skin health. Keeping an eye on the UV Index can help you make informed choices about outdoor activities, ensuring you enjoy the beautiful weather while safeguarding your skin from potential harm.
The UV Index throughout the day tells a compelling story of rising sun intensity. Starting off at a mellow 1 at 07:00 AM, it gradually increases to a moderate 2 by 09:00 AM. As the clock strikes 10:00 AM, the index soars to 5, marking the onset of stronger rays. With the sun at its peak, the index reaches an impressive 11 at 12:00 PM and 14 at 1:00 PM, signaling the highest risk for unprotected skin. Although it remains high at 14 from 1:00 PM to 2:00 PM, it soon begins to dip, falling to 9 by 4:00 PM and further down to 3 at 6:00 PM. As daylight dims, the UV Index retreats to a safe 1 by 7:00 PM, reminding us of the sun's powerful influence during the midday hours. Be sure to protect your skin when the index is at its highest!
