Luke Combs penned the song with frequent writing partner Ray Fulcher and Jordan Walker of the duo Walker McGuire. He recalled to The Boot
the session that produced the track:
"I don't know if there's necessarily a personal side to it as much [as] it was a good story we wrote. I had the title in my phone; I keep titles in my phone. It was just one of those things where I came in and had the title, 'When It Rains It Pours.'
I thought it was going to be a sad song. Jordan Walker was like, 'Why don't we make it a fun, not sad, thing?' So me and Jordan and Ray wrote it, and it turned out great.
We tried to have fun with it and write it in a '90s, early-Brad Paisley kind of song, is what we were going for with that thing. Luckily, in my opinion, we nailed it. People seem to love it so far."
