Apple TV announced this week that filming on Silo Season 4 has officially wrapped. The announcement comes as we still await the streamer to announce when the sci-fi series will return for its third season.
Based on the Silo book series by Hugh Howey, Seasons 1 and 2 mostly adapted the 2011 book Wool,f ocusing on life inside the underground silo and Juliette's investigation into a series of suspicious deaths that uncover a much larger conspiracy.
Season 2, which aired from November 2024 to January 2025, continued Juliette's story outside the silo, but ended with an unexpected flashback that teased at ime before the silos existed. Many fans are eager to return to the dystopian universe, but Apple TV has not yet announced when Season 3 will premiere.
Apple chose to film Silo Seasons 3 and 4 back-to-back to finish the story efficiently and keep production consistent as the show moves into its final chapter. It's already been confirmed that the series will conclude with Season 4, covering material from the Shift and Dust novels.
Despite no official announcement yet, many believe eason 3 will air at some point this year. Filmin gon the third season wrapped in May 2025, but the show's heavy visual effects and post-production are known to take a while.
For comparison, filming on Season 2 wrapped in March 2024, while the season aired about eight months later in November 2024. We're already behind that same eight month schedule with Season 3, but we're hoping it will arrive by end of 2026.
