Understanding the UV Index is crucial for residents of Doctor Cecilio Baez, Paraguay, where the climate features warm summers and significant sun exposure. With UV levels that can peak at 7 around midday, being aware of these fluctuations is essential for preventing sunburn and protecting skin health. High UV levels increase the risk of skin damage, making it vital to take precautions, especially during the hottest hours. Given the Cfa climate typical of the region, where humid subtropical conditions prevail, awareness of UV exposure risks can help you enjoy the sun safely while safeguarding your skin for the long term.
The UV Index reveals an early morning reprieve, starting at a gentle 1 at 7:00 AM and remaining low through 9:00 AM. However, as the sun climbs, intensity increases sharply, peaking at a 7 around noon, signaling the most potent UV exposure of the day. The early afternoon maintains a respectable UV level of 6 at 1:00 PM before gradually tapering off. By mid-afternoon, it drops to 4, then swiftly declines to 1 by 4:00 PM, and finally settles at 0 by 6:00 PM, marking the day's end for UV concern. This hourly trend underscores the importance of sun safety during peak hours, especially between 10 AM and 2 PM.

Throughout the year, the UV Index exhibits significant seasonal changes, with high-risk months primarily occurring during the late fall and winter, specifically from October to March, where the index reaches extreme levels (13-15) and a burn time of just 10 minutes. As we transition into spring and summer, UV exposure decreases to high levels in May and June (7-8) and allows for longer burn times of 25 minutes, though still caution is warranted. August and September remain critical, returning to very high levels with a burn time of 15 minutes. Visitors and residents should take precautions year-round, especially during the extreme months by wearing protective clothing, applying sunscreen regularly, and avoiding direct sun exposure during peak hours to mitigate the risks of harmful UV radiation.
