In Armacao, Brazil, awareness of the UV Index is crucial for maintaining healthy skin and preventing painful sunburns. With a Cfa climate characterized by warm summers and ample sunshine, understanding UV levels becomes essential, especially during peak hours when the index reaches up to 5. This means that protection is vital from about 11:00 AM to 1:00 PM, when UV radiation can pose significant risks. By keeping an eye on the UV Index, locals and visitors alike can enjoy the sun safely while safeguarding their skin health and overall well-being.
The UV Index throughout the day reveals a notable oscillation in sun exposure. Early morning hours from 7:00 AM to 8:00 AM see a mild UV Index of 1, indicating minimal risk. As the sun ascends, the intensity rises sharply, peaking at 5 between 11:00 AM and 1:00 PM, marking the day’s highest risk for skin damage. Following this peak, the index tapers off in the afternoon, returning to a manageable 2 by 3:00 PM, before descending to a safe 0 by 6:00 PM. It’s clear that the primary concern for sun safety lies during mid-day; ensure to protect your skin when the UV Index hits its zenith!
