ELI5: Clouds are made up of water that has evaporated, in Summer when it is hotter and more water is evaporating there is often far less clouds than in Winter when it is cold and there are lots of clouds. What causes this?

My head hurts trying to think about this...

Truly evaporated water is invisible, it’s basically air. Think about the totally clear area right at the top of a boiling kettle. Clouds are tiny droplets if water, white and visible, like steam. The summer heat evaporates lots of water,  but it only forms clouds in certain areas where it’s gets pushed up to colder parts of the sky. That’s part of why some places have summer thunderstorms, with hail sometimes.
