Other forms: summers; summering; summered
Summer is the season after spring and before autumn. In the summer, the weather is warmer and many students get a break from school.
If you live in the Northern Hemisphere, summer lasts from June to September, and if you travel in December to Australia or somewhere else in the Southern Hemisphere, you'll get to experience summer all over again. When fancy people talk about what they do during the summer, they may use it as a verb: "Oh, we summer in Maine."
