Sol-air temperature refers to the temperature of the air surrounding us outside. The sun's energy heats the air and the Earth's surface. This temperature that we feel is called sol-air temperature. It can be affected by different things such as air movement, humidity, and the angle of the sun. When the sun is shining very brightly, sol-air temperature can feel very warm. Conversely, when it is cloudy or at night, sol-air temperature can be much cooler. It's important to wear appropriate clothing and protect our skin from harmful UV rays because of sol-air temperature changes.
