• "California Rain" emerged from James Marriott's 2025 American tour, with the songwriting process spanning multiple locations across the United States. Marriott started sketching the song in Caldwell, Idaho, before tightening it up during rehearsals in Seattle and finally finishing the lyrics in California, where the title, and the irony, locked into place.
  
  "We were going to play some of the older songs on the last tour of America that we hadn't played in a while... I thought, 'I don't really want to play these. I don't think they sound very good," Marriott told Official Charts. "What is the best representation of me? Probably the one I wrote in Caldwell, Idaho."
• "California Rain" was workshopped during soundchecks, with audience reactions acting as an informal focus group. If it landed, it stayed. If it didn't, it went back under the microscope.
  
  With just two weeks between the US and UK legs of the tour, Marriott recorded the track while continuing to perform it nightly. His Finnish producer Psylla flew in and mixed the song in real time as it was being played. The music video followed immediately after the tour wrapped.
• Marriott penned the song about homesickness and being away from the UK. "It's a song written on tour about culture shocks and touring the United States as an Englishman," he explained. "Its lyrics take semblance from missing your home life/people whilst self-doubt and imposter syndrome captures you whilst away."
• One of the things Marriott missed from the UK was the weather:
  
  The rain won't stop me now
  
  As Marriott surveyed California's cloudless skies, he pined for some rain. "In the spirit of not knowing what you have until you don't have it," he explained, "'the rain won't stop me now' takes the thing that British people complain about the most and transforms it into something hopeful and to be missed."
  
  Sometimes, the song suggests, you don't want blue skies. You want weather.
• The music video, directed by Herbie Elton, leans hard into metaphor. Marriott plays a weatherman condemned to eternal sunshine, while also appearing as an anthropomorphised, smug sun, the sort of character you'd cross the street to avoid.
