Understanding the UV Index is crucial for residents of Nanawa, Paraguay, where high sunscreen awareness can significantly impact skin health and prevent sunburn. With the region's Cfa climate, characterized by hot summers and mild winters, UV levels can soar, particularly during midday hours when values peak at 6. By staying informed about daily UV exposure risks, you can take essential precautions to protect yourself and enjoy the beautiful Paraguayan sun safely.
The UV Index throughout the day presents a dynamic range of sun exposure, starting from a maximum of 0 at 07:00, signaling safe conditions for early risers. As the morning unfolds, it gradually climbs to 1 by 08:00 and remains stable until 09:00. The real action begins around 10:00, escalating to 3, followed by a sharp rise to 5 at 11:00. At 12:00, the peak is reached with a UV Index of 6, persisting until 14:00. Post-peak, levels decrease steadily, dipping to 4 by 15:00, and then further down to 2 at 16:00. As the day winds down, the index returns to safe levels of 1 by 17:00 and finally drops back to 0 by 19:00, marking a clear transition from peak sun intensity to evening calm. Always remember to take precautions during those midday hours when the UV Index is high!
