Understanding the UV Index is crucial for residents of Alto Vera, Paraguay, where the Cfa climate brings warm temperatures and abundant sunshine throughout the year. Being informed about UV levels helps residents safeguard their skin against harmful ultraviolet rays, which can lead to painful sunburns and long-term skin health issues. During peak sunlight hours, particularly between 10:00 AM and 12:00 PM, UV Index values can reach as high as 7, indicating a high risk of harm from unprotected sun exposure. By staying aware of these levels, you can enjoy your time outdoors while effectively protecting your skin!
The hourly UV index reveals an engaging story of the sun's intensity throughout the day. At 07:00, a gentle start with a UV Index of 1 sets the stage for the morning. As the sun climbs, it reaches 2 by 08:00 and steadily rises to 4 by 09:00, signaling a shift. The peak intensity occurs at 11:00 and 12:00, both hitting a UV Index of 7, reminding everyone to take precautions. As afternoon unfolds, the index dips to 6 at 13:00, then gradually decreases to 4 by 14:00. The sun’s rays soften in the late afternoon, dropping to 2 at 15:00, and finally retreating to 1 at 16:00. By 17:00, it tumbles to 0, signaling the end of the sun’s powerful sway, with the UV Index staying at 0 for the remainder of the evening. Plan your sun exposure wisely!
