Understanding the UV Index in Arrufo, Argentina is essential for safeguarding your skin against harmful UV radiation, especially given the region's temperate climate (Cfa) that often experiences peaks in UV exposure. Awareness of UV levels is critical, as even low indices can lead to sunburn and long-term skin health issues. With maximum UV readings reaching 4 around midday, residents and visitors must take proactive measures to enjoy the sun safely, ensuring they protect their skin while embracing the beauty of Arrufo’s sunny days.
The UV Index skyrockets as the sun climbs higher, peaking at 12:00 PM with a level of 4, indicating a moderate risk of harm from unprotected sun exposure. As the daylight progresses, 07:00 starts at a cool 0, gradually rising to 1 by 08:00 and 09:00. By 10:00, it hits 2, and by 11:00, it reaches 3, setting the stage for that midday high. Later in the afternoon, from 12:00 to 14:00, the index maintains its strength at 4, before gently tapering off as the sun begins to set. By 19:00, it’s back to 0, marking the end of a sun-filled day.
