Question:
What time of day do clouds appear the most and why?

Replies:
Locally, clouds often appear during later part the day as land and water heat up from the sun. The sun's heat evaporates water and, being warm, the water vapor rises. When it gets high enough, the vapor condenses into droplets which we see as clouds. This kind of cloud is the puffy "fair weather cumulus" we often see on otherwise clear and sunny days.

Clouds from larger causes, such as warm and cold fronts or hurricanes and other storms, can be seen any time of day.

Hope this helps. R. W. "Mr. A." Avakian
