Understanding the UV Index is crucial for residents of San Juan Bautista, Paraguay, where the warm climate and ample sunshine can increase the risk of harmful UV exposure. By keeping an eye on UV levels, you can effectively prevent sunburn and safeguard your skin's health, ensuring that outdoor activities remain enjoyable and safe. The typical climate here, classified as Cfa, means you’re exposed to varying UV risks throughout the day, with peak values reaching 6 around midday. So, whether you’re out enjoying the sun or simply going about your daily routine, staying informed about the UV Index is key to protecting your skin and promoting overall well-being.
The UV Index starts low in the early morning, with a maximum of 1 at 07:00 and 08:00, making it a safe time for outdoor activities. As the day progresses, the intensity rises sharply, peaking at 6 between 11:00 and 12:00—the perfect time to take precautions if heading outside. By 13:00, it dips slightly to 5, and a more noticeable decline occurs in the afternoon, falling to 2 by 15:00. As the sun sets, the UV Index drops off sharply, reaching 1 by 16:00, and finally 0 past 18:00. It’s clear that midday sun calls for some sun safety measures, but the later hours provide a much more forgiving environment for enjoying the outdoors!
