Evening DJ Shaun Keaveny is to take over the slot from 2 April as part of a schedule shake-up that also sees Elbow frontman Guy Garvey join the station.
Jupitus said he would return to stand-up comedy and appear in a play at the Edinburgh Fringe.
Calling his time there an "unbridled joy", he added: "I expect to be back next time there's a bug going round."
Keaveny joined 6 Music last year from indie station Xfm, where he hosted the Friday breakfast show and helped the station win a Sony award for its Rock School feature.
6 Music controller Lesley Douglas said: "His irreverence, humour and love of music will make him the perfect new breakfast show presenter as we move 6 Music into its sixth year.

"He is one of those rare broadcasting talents who is appointment listening."
She said Jupitus was a "hard act to follow", adding: "I look forward to welcoming him back to 6 Music at some point in the future when he has caught up on his sleep."
Elbow singer Guy Garvey gets a Sunday night show in the new schedule, while musician and film-maker Don Letts gains a Friday night programme.
Channel 4 music presenter George Lamb takes over the station's nightly Dream Ticket slot, which features archive BBC sessions.
