In Rio Pomba, Brazil, understanding the UV Index is crucial for safeguarding your skin and overall health. As a region characterized by a humid subtropical climate (Cwa), the sun can pose significant risks, especially during peak hours when UV levels soar. Knowing the UV Index not only helps in preventing painful sunburns but also plays a vital role in reducing the long-term risks of skin damage and various skin cancers. With values peaking at 8 around noon, residents and visitors alike should stay informed about UV levels to enjoy outdoor activities safely while protecting their skin. So, whether you’re basking in the sun or out exploring, pay attention to the UV Index to keep your skin healthy in this beautiful Brazilian locale.
As the sun rises, the UV Index begins its ascent, starting at a gentle 1 by 7:00 AM. By 8:00 AM, it nudges up to 2, signaling a mild increase in UV exposure. The intensity heats up quickly, reaching a moderate 4 by 9:00 AM, before hitting its peak of 8 from 11:00 AM to 12:00 PM. This is the prime time for sun safety awareness! After noon, the UV Index gradually declines; by 3:00 PM, it recedes to 3, and as the day wanes, it drops significantly to 1 by 4:00 PM. By evening, UV levels have diminished, reaching 0 by 6:00 PM, offering a reprieve from the sun’s rays.
