In Canales de la Sierra, Spain, understanding the UV Index is crucial for safeguarding your skin and overall health. With a climate classified as Cfb, characterized by moderate temperatures and significant sun exposure, awareness of UV levels can help you prevent painful sunburns and reduce the risk of long-term skin damage. During peak hours, particularly between 12 PM and 3 PM, the UV Index can reach a high of 10, indicating a very high risk of harm from unprotected sun exposure. Being informed allows you to enjoy the beautiful outdoors while taking the necessary precautions to protect your skin.
The UV Index today presents a clear picture of the sun's intensity as it rises and falls throughout the day. Starting off gently at a maximum of 1 between 7:00 AM and 8:00 AM, the index steadily climbs to 3 by 10:00 AM. However, from 11:00 AM to 3:00 PM, the UV rays reach their peak, hitting a striking 10 by 1:00 PM—dangerous levels warranting protection! After this peak period, the intensity begins to decline, falling to 6 at 5:00 PM and tapering off to 2 by 7:00 PM. While the early hours are safe for outdoor activities, it’s essential to stay vigilant during midday when UV exposure is at its most potent. Remember to apply sunscreen and seek shade when necessary!
