On December 13, 2018, a press conference was held to reveal the film and announce it would be released on July 19, 2019. The first teaser trailer debuted on April 10, exactly 100 days before the premiere. The second trailer was released on May 28. Producer Genki Kawamura presented a work in process screening on June 14, 2019, at the Annecy International Animation Film Festival in France that was open to industry professionals and students but not the general public.

During its screening in Japan, many convenience stores such as Lawson launched food products inspired by the film. Weathering with You screenings in 4DX and MX4D begins from September 27 onwards.
