In Palmares do Sul, Brazil, being aware of the UV Index is crucial for protecting your skin and overall health. With the region's Cfa climate, residents and visitors alike face varying UV exposure throughout the day, peaking around midday when levels reach 5. Understanding these UV levels is essential not just for preventing sunburn, but also for safeguarding against long-term skin damage. As the sun climbs higher, from a low of 1 in the morning to a significant 4 and 5 around noon, knowing when to seek shade and apply sunscreen can make all the difference in enjoying the outdoors safely.
At dawn, the UV Index begins at a gentle 0 by 07:00, indicating minimal exposure risk. As the sun rises higher, the index steadily climbs, reaching 1 at 08:00 and peaking at 5 between 12:00 and 13:00, when the sun’s rays are at their most intense. During these peak hours, it’s wise to don your sunscreen and protective gear. Following this zenith, the index gracefully descends, dropping to 4 at 14:00 and tapering off to 2 by 15:00. As the afternoon fades to evening, the UV levels reduce significantly, returning to a safe 0 by 18:00. This hourly UV pattern underscores the importance of sun safety during peak daylight hours!
