Scientific common sense: Why are there no clouds in the summer sky?

Because there are no clouds, there is sunshine, otherwise the sunshine will be blocked by clouds. There are also "Cloudless Days in Wan Li" in winter, and it often rains in summer, with many cloudy days. Why there are no clouds in the summer sky should not be an accurate objective phenomenon.

If you think it is always sunny in May, it has something to do with your local climate. Maybe you have a temperate continental climate, and now it is dry and sunny, not rainy. This is related to the height angle of the sun in summer, but the weather on the same latitude of the earth will not be the same, and the weather and climate also depend on local geographical location, land and sea distribution and other factors.

The weather is always changeable, sometimes sunny and sometimes cloudy. Some places are sunny and some places are cloudy. You can look at the weather forecast and satellite pictures to see where the clouds are distributed.
