What weather does hail usually appear in?

Usually, hail will appear in sunny weather in autumn.

Hail comes from cumulonimbus clouds and is most common in summer or at the turn of spring and summer. When the raindrops in the cloud are carried to the high altitude below 0℃ by the rising airflow, they solidify into small ice beads; With the increase of water vapor updraft, strong hail may be formed. In summer with strong sunshine, the water vapor content in the air is high and the convection is strong, which creates conditions for hail.
