In Altarejos, Spain, understanding the UV Index is crucial for protecting your skin and ensuring your overall health. With the sun's rays reaching their peak during midday, the risk for sunburn increases significantly, especially between 11 AM and 3 PM when the UV Index elevates to levels as high as 12. Awareness of these levels helps residents and visitors take proactive measures against skin damage and long-term health effects. Altarejos, located in a Csb climate zone, experiences a unique blend of Mediterranean sunshine and seasonal variations, making it essential for everyone to stay informed about UV exposure risks and to enjoy the beautiful outdoors safely.
As the sun rises, the UV Index begins at a mild 1 at 07:00, providing a gentle reminder to enjoy the day with minimal sun protection. However, by 10:00, the index surges to a moderate 4, alerting us to take more care during outdoor activities. The intensity peaks dramatically at 12:00, reaching a staggering 9, and by 13:00, it escalates to a maximum of 11—a critical time for sun safety. From there, the UV levels gradually decline, with readings of 12 at 14:00, 11 at 15:00, and tapering off to 4 by 18:00. As evening approaches, the index drops to a low 2 at 19:00, offering a much more forgiving environment for those looking to enjoy the outdoors as the sun sets. It's a day to be mindful and enjoy the sunny moments while taking protective measures during peak hours!
