Rain photos all look similar: a window, a puddle, a street turned shiny, a mug held up against grey light. The caption is the part that decides whether the post reads as gloomy or warm. Everything below is original and grouped by mood, and the AI Instagram post generator will rewrite any of it in your own phrasing.

How to use these
Let the caption say the part the photo cannot, which for rain is usually the sound or the temperature, not the view. Front-load the best few words, because the feed cuts a caption off after a line and most people never tap for the rest, so check it against a caption length checker if the line is long. Keep hashtags in the first comment. Rainy day posts tend to do well in the late afternoon when people are already indoors and scrolling, so it is worth writing a few when the weather turns and letting them go out across the week rather than posting six in one afternoon. BulkPublish can space them out with scheduling.
