In November 2008, an anime adaption of Natsu no Arashi! was announced.[4] The anime series was produced by Shaft, directed by Akiyuki Shinbo and Shin Oonuma, with Katsuhiko Takayama acting as series composition writer and Kazuhiro Oota (Shaft) designing the characters for animation.[5] Oota and Yoshiaki Itou (Shaft) served as chief animation directors, and Ken Sato composed the music. The series was broadcast from April 5, 2009, it had a total of 13 episodes.[5][6] Of its 12 episodes, 6 were produced in-house at Shaft, while 7 were outsourced: episodes 3, 5, 9, and 11–13 to Studio Pastoral; and episode 10 to Mushi Production.
Four pieces of theme music are used during the first season—one opening theme, one closing theme and two special closing themes for episodes six and eleven. The opening theme is "Atashi dake ni kakete" (あたしだけにかけて) by Omokage Lucky Hole and the closing theme is "Kirari Futari" (キラリフタリ) by Ryōko Shiraishi.

Itou did not return as Oota's co-chief animation director, and Oonuma acted as series director for only the first seven episodes. Kenichi Ishikura replaced Oonuma for the final six episodes.
