Clouds love this long-wave infrared radiation. The tiny water particles in them soak it right up.

Have you ever noticed that a cloudy night often is warmer than a clear one? Those clouds are absorbing that radiation coming off the Earth and radiating a lot of it back toward the ground, acting like a big infrared blanket over you.

A cloudy day can be a different story, depending on the season. In spring and summer, the same clouds that kept you warm at night now are preventing the sunlight from reaching you. More often than not, a calm cloudy summer day is cooler than a calm sunny day. In winter, clouds during the day often make temperatures near the ground warmer than on a clear day.
