In Taubate, Brazil, being aware of the UV Index is crucial for safeguarding your skin and overall health. Understanding UV levels helps prevent potential sunburn and long-term skin damage, particularly in this Cfa climate zone, where direct sunlight can be intense. As you navigate through the day, you'll notice that UV exposure peaks between 10:00 AM and 1:00 PM, reaching levels of 8—a significant risk for sun-related health issues. Stay informed and protect your skin—knowledge is your first line of defense against harmful UV rays.
The UV Index data paints a vivid picture of sun exposure throughout the day. In the early hours, from 7:00 AM to 9:00 AM, the UV Index remains low, peaking at only 1. However, as the sun climbs higher, from 10:00 AM to 12:00 PM, it surges to 8 at noon, marking the peak of solar intensity. The afternoon sees a slight decline, with the index dropping to 5 at 2:00 PM and further to 3 by 3:00 PM. As evening approaches, the UV levels plummet back to a safe 1 by 4:00 PM, and the sun's diminishing rays result in a 0 by 6:00 PM, signaling a welcome reprieve from UV exposure. Essentially, the peak intensity occurs during midday hours, highlighting the importance of seeking shade and wearing protection during these critical hours.
