Written by Crow, Doyle Bramhall II, and Justin Stanley, the song features a breezy, smooth tempo, with a noticeable dose of 1970s R&B influence.

In the music video, Crow goes to the park during a sunny day, staging an intimate set with her band.

Amar Too from AOL Music said that "'Summer Day' might just be the perfect, flagship single for your summer night drives, or evenings spent in your favorite rocking chair on the patio.

The music video for the song was shot in Nashville, and was released on July 14, 2010 on VEVO and was directed by Wayne Isham.
