In Paraiso das Aguas, Brazil, understanding the UV Index is crucial for safeguarding your skin against harmful ultraviolet radiation. With UV levels peaking around 11 AM to 1 PM, residents and visitors must stay vigilant to prevent sunburn and protect overall skin health. This tropical climate, characterized by high temperatures and abundant sunshine, often leads to increased UV exposure, making it essential to keep an eye on the daily UV forecasts. By staying informed, you can enjoy the beautiful outdoors while keeping your skin safe and healthy.
As the sun rises, the UV Index begins its ascent, starting at a gentle 1 at 7:00 AM and gradually climbing to reach its peak at 11:00 AM with a powerful 8. This surge prompts an alert as midday approaches, where 10:00 and 11:00 cut through the morning glow with 6 and 8 respectively. By 12:00 PM, the levels slightly dip to 7, but the UV radiation remains significant. In the early afternoon, the index falls to 6 at 1:00 PM and continues its descent until it hits 4 at 2:00 PM. By late afternoon, the UV threat dwindles, sliding to 2 at 3:00 PM, before dropping to 1 by 4:00 PM. As the sun begins to set, the UV Index completely fades, reaching 0 by 5:00 PM and remaining there into the evening.

Throughout the year, the UV Index experiences significant fluctuations, with the highest levels recorded from January to April, consistently categorized as extreme. These months, particularly February (UV Index 17), present the greatest risk, with a rapid burn time of just 10 minutes. As the season transitions into late spring and summer, the UV Index lowers to a very high level during May to July, allowing for slightly longer burn times of 15 minutes. However, the risks remain notable, especially as the summer draws to a close in August, where it spikes back to an extreme category. Visitors and residents should exercise caution year-round, particularly between January and April and during August and October, by applying sunscreen, wearing protective clothing, and limiting sun exposure during peak hours to protect their skin from harmful UV rays.
