In a summer issue of Vibe, the song was included on a list of the top songs for a summer playlist. Research director Laura Checkoway reviewed the remix of the track and stated: "Ghost's game is tight." In an Amazon.com editorial review, Tom Keogh stated that the song "proves a breezy dance number." Tim Sendra of Allmusic wrote that "Summertime" features "a wonderful vocal from Beyoncé."
