In San Claudio, Spain, being aware of the UV Index is essential for protecting your skin and overall health. Understanding the UV levels throughout the day can significantly aid in sunburn prevention and long-term skin care, especially during peak hours when the index reaches a maximum of 10 around 2:00 PM. With its Csb climate, San Claudio experiences varied sunshine throughout the year, but during the height of summer, the risks of UV exposure become particularly pronounced. Stay informed and enjoy the sun safely by monitoring the UV Index!
As the sun rises, the UV Index begins its gradual ascent, peaking at an impressive 10 between 2 PM and 3 PM. Starting at a mild 1 at 7 AM and 8 AM, the index climbs steadily, hitting 3 by 10 AM and reaching 5 by 11 AM. The afternoon sun brings the strongest rays, with a 7 at noon, then soaring to 9 at 1 PM. Caution is advised during this peak, as UV levels dip slowly in the late afternoon; at 4 PM, it drops to 9, followed by a gentle decline to a comfortable 3 by 7 PM. Remember to protect your skin during the intense midday hours!
