[50] The artwork for Un Verano Sin Ti features a sad one-eyed heart in front of a vibrant beach setting with the light blue ocean, beaming sunset, breezy palm trees, happy dolphins, and pink flowers that was designed by the L.A.-based artist and graphic designer Adrian Hernandez, professionally known as Ugly Primo, with whom Bad Bunny has been in a friendship with since 2018.

Hernandez explains even further that he made about seven versions, in different styles and aesthetics, based on a drawing that Bad Bunny gave him, and a little after six months, the cover art of Un Verano Sin Ti was finally finished and unveiled to the public on May 4, 2022, just two days before the official release of the album.

[53] David Crone of AllMusic writes, "Un Verano is not only a seasonal statement-piece but a testament to Benito's singular songwriting -- across genres, generations, and even languages, he works to produce enduring landmarks that trace universal joys, sorrows, and passions.

... With the sun-kissed Un Verano Sin Ti, Bad Bunny continues to proudly give pop music some much-needed flavor, swagger, and sounds by way of the Caribbean.

[78] Un Verano Sin Ti became Bad Bunny's first album to reach the top 10 on the music charts of Canada, Italy, the Netherlands, and Switzerland.
