What Are Idioms for Raining?
Idioms for raining are set phrases that use the word rain to describe either real weather or something unrelated to weather.
They split into two groups. The first group describes heavy rain, such as “raining cats and dogs.” The second group uses rain as a picture for health, plans, money or luck, such as “right as rain.”
Hearing the word rain does not always mean someone is talking about the weather. A speaker can say “it never rains but it pours” on a bright sunny day and still be understood. Keep that in mind, and the rest of this guide gets easier.
Idioms for Raining Hard
Raining cats and dogs, raining buckets and raining stair-rods all describe very heavy rain.
Raining Cats and Dogs
Meaning: It is raining very heavily.
Origin (unknown): Phrase Finder says no one knows who coined this 17th-century phrase. A close version appears in a 1653 play by Richard Brome, which has “dogs and polecats” falling. The form we use today first appears in Jonathan Swift’s 1738 book Polite and Ingenious Conversation.
A popular story says pets slipped off thatched roofs in the rain. Phrase Finder calls this nonsense, and traces its spread to a 1999 email. Another guess links the phrase to a French word for waterfall, but there is no evidence for it.
Examples:
- “We moved sports day indoors because it was raining cats and dogs.”
- “Take a coat. It’s raining cats and dogs out there.”

Rain Idioms That Aren’t About Weather

Right as Rain
Meaning: Perfectly well or in good working order.
Origin (unconfirmed): Phrase Finder says it dates to the mid-to-late 1800s in the UK. Older forms included “right as nails” and “right as ninepence.” The reason rain was chosen is unclear. One guess says rain is a sure thing in UK weather. Another links rain to good crops and good fortune.
Example: “After two days of rest, my cold is gone and I’m right as rain.”
Take a Rain Check
Meaning: To decline an offer now but hope to accept it later.
Origin (documented): Dictionary.com describes a rain check as a ticket for future use, given to spectators when rain stopped an outdoor event such as a baseball game. It was first recorded in 1880–85. The polite “maybe later” sense grew from that ticket. Phrase Finder marks the idiom as mostly American.
Example: “I can’t make the team lunch today. Can I take a rain check?”

Which Rain Idiom Fits the Moment?

- Declining an invitation: “Can I take a rain check?” sounds polite and friendly.
- Writing a business report: use “heavy rain” or “postpone.” Idioms can sound too casual there.
- Comforting someone: “You’ll be right as rain soon” sounds warm.
- Talking about money: “save for a rainy day” is neutral and clear.
Common Mistakes with Rain Idioms
Learners most often stretch an idiom past its meaning, mix up sound-alike words, or use a casual phrase in a formal place.
- Using “raining cats and dogs” for light rain. The phrase describes very heavy rain only.
- Saying “take a rain check” to refuse for good. It suggests you want to accept later, so use it only if you mean it.
- Confusing sound-alike words. Write “right as rain,” not “reign” or “rein.” For the ticket idiom, “rain check” is the usual US spelling, and “cheque” sometimes appears in British writing.
- Taking “it never rains but it pours” as a weather report. It describes bad luck and works on a sunny day too.
- Using rain idioms in formal reports. Choose plain words such as “heavy rain” or “reschedule.”
