Summer

The Northern Hemisphere, the northern half of the earth, has summer weather during late June, July, August, and early September. Summerlike days sometimes occur in mid-autumn. In the Southern Hemisphere, summer lasts from late December until early March.

The highest summer temperatures usually occur in the middle of a continent.

During summer in North America, warm southern winds carry moisture north from the Gulf of Mexico to central and eastern North America.

They can bring warm, humid weather to much of the region east of the Rocky Mountains and as far north as Canada.
