Weather Idioms: Under the Weather, Raining Cats and Dogs, A Storm in a Teacup

What this session covers

Weather idioms are common in English. Weather words — sun, rain, clouds, storm, thunder — appear in many fixed expressions, often with meanings far from the literal weather. 'Under the weather' (feeling ill). 'Raining cats and dogs' (raining heavily). 'A storm in a teacup' (a fuss about something small). 'Fair-weather friend' (only there in good times). 'On cloud nine' (very happy). 'Come rain or shine' (no matter what). 'Steal someone's thunder' (take the attention away from them). Like all idioms, the meanings cannot be guessed from the parts. 'Under the weather' has nothing to do with being literally under weather — it means feeling unwell. 'On cloud nine' has nothing to do with actual clouds — it means very happy. Topic-based teaching — grouping idioms by weather — makes them easier to remember. This lesson is the fifth in the topic-based idioms series, after body (#45), animal (#50), food (#55), and money (#59). It covers about 12 of the most useful weather idioms with clear meanings and examples.

Personal Reflection

Before you start — think honestly about your own teaching and experience.

Q1
When your students meet a weather idiom like 'under the weather' or 'a storm in a teacup' in reading or conversation, do they recognise it as a fixed expression with its own meaning, or do they try to translate the weather references literally?
Q2
Which of these have you seen your students get wrong or avoid using altogether?

Discover the Pattern

Look at the examples. Answer each question before reading the explanation — this is how your students will learn too.

1
Idioms about FEELINGS:

under the weather (= feeling unwell, slightly ill)
I am a bit under the weather today — I think I will stay home.

on cloud nine (= very happy)
When she got the job, she was on cloud nine for a week.

in a black mood / under a cloud (= unhappy, in trouble)
Do not talk to him today — he is in a black mood. / She has been under a cloud at work since the mistake.

Why do English speakers use weather words for feelings? What is the connection?

Weather and feelings have a natural connection in English. Sunny weather makes people happy; cloudy or rainy weather makes them feel low. The idioms reflect this. 'Under the weather' originally meant feeling the bad effects of bad weather — and now means feeling unwell generally. 'On cloud nine' uses the high position above clouds as a metaphor for happiness — being so happy you are floating. 'In a black mood' uses dark weather (storms) as a metaphor for an angry or negative mood. 'Under a cloud' uses cloud cover as a metaphor for trouble or suspicion hanging over someone. The weather-feeling connection makes these idioms intuitive once you see it. Students who notice the connection can remember the idioms more easily.

2
Idioms about PROBLEMS and SITUATIONS:

raining cats and dogs (= raining very heavily)
We could not go out — it was raining cats and dogs.

a storm in a teacup (= a fuss about something small or unimportant)
The argument was just a storm in a teacup — the next day everything was fine.

weather the storm (= survive a difficult time)
The company managed to weather the storm and stay in business.

take by storm (= achieve sudden success)
The new song took the country by storm.

Why do storms appear so often in idioms about problems?

Storms are dramatic, sudden, and usually problematic — so they make a powerful image for difficult or sudden situations. 'A storm in a teacup' uses the smallness of a teacup combined with the drama of a storm — for a fuss that seems big but is actually small. 'Weather the storm' uses surviving bad weather as a metaphor for surviving a difficult time. 'Take by storm' uses the suddenness of a storm for sudden success that catches people unprepared. 'Calm before the storm' (another idiom) uses the strange quiet before bad weather as a metaphor for the period before a difficult event. Each idiom uses the dramatic qualities of weather — its power, suddenness, unpredictability — to describe situations in life. Students should learn the storm idioms together as a group about dramatic events.

3
Idioms about RELATIONSHIPS and COMMITMENT:

fair-weather friend (= a friend only in good times)
She turned out to be a fair-weather friend — she disappeared when I needed help.

come rain or shine (= no matter what — in any condition)
My father walks five kilometres every day, come rain or shine.

steal someone's thunder (= take attention away from someone)
She stole my thunder by announcing her engagement at my birthday party.

take a rain check (= postpone something to another time)
I cannot come tonight, but can I take a rain check?

Why do these idioms describe social situations?

Each weather idiom describes a social or interpersonal situation through a weather metaphor. 'Fair-weather friend' uses good (fair) weather as a metaphor for good times — a friend who only appears when life is sunny but disappears in bad times. 'Come rain or shine' uses any weather (good or bad) as a metaphor for any condition — keeping a commitment regardless of circumstances. 'Steal someone's thunder' uses the dramatic noise of thunder as a metaphor for attention or recognition — taking the attention that should belong to someone else. 'Take a rain check' is American in origin — originally a ticket given when a sports event was cancelled because of rain, allowing you to come another day. It now means postponing any plan to a later time. These social-situation idioms add personality and colour to descriptions of relationships and commitments.

The Pattern — What You Just Discovered

Weather idioms are fixed expressions using weather words for non-literal meanings. Feelings: under the weather (ill), on cloud nine (very happy), in a black mood (angry/down). Problems: raining cats and dogs (heavy rain), a storm in a teacup (small fuss), weather the storm (survive difficulty). Relationships: fair-weather friend (only there in good times), come rain or shine (in any condition), steal someone's thunder (take attention), take a rain check (postpone). Each is a fixed chunk that must be learned. Most are casual to neutral in register and rarely fit formal academic writing.

Usage Notes

NOTE 1 — Weather and feelings are linked: Many weather idioms about feelings use the natural connection between weather and mood. Sunny = happy, cloudy = sad, stormy = angry. Knowing this connection helps memory.

NOTE 2 — Group by topic for memory: Learning all the feeling idioms together, then all the problem idioms, then the relationship idioms, makes them easier to remember. The topic-grouping approach creates strong memory connections.

NOTE 3 — Most are casual or neutral: Weather idioms are mostly informal or neutral. They work in everyday speech, friendly emails, and informal writing. They rarely fit formal academic writing. Save them for casual contexts.

NOTE 4 — Idioms are fixed: Most weather idioms cannot be changed. 'Under THE weather' (with 'the'). 'On cloud NINE' (specifically nine — not eight or ten). 'A storm in a TEACUP' (specifically teacup — not cup or mug). 'Take a rain CHECK' (specifically check — not ticket). Exact wording matters.

NOTE 5 — Dramatic weather, dramatic meaning: Storm idioms are particularly dramatic — they describe sudden, powerful situations. 'Take by storm' (sudden success). 'Weather the storm' (survive difficulty). 'A storm is brewing' (trouble is coming). The dramatic weather makes the idioms vivid.

Note

Weather idioms are common in everyday English — in conversation, films, songs, and stories. Students who do not know them miss meaning frequently. The topic-grouping approach makes them easier to remember than learning random lists. Pairs with body (#45), animal (#50), food (#55), and money (#59) idioms — together five strong topic-based foundations. The teaching focus at this level should be on recognition first (understanding idioms in reading and listening) and active production second. Students who use weather idioms confidently sound noticeably more fluent in casual contexts.

💡

Use real weather to teach weather idioms. Look out the window — is it sunny? Then use the sunny idioms (on cloud nine, every cloud has a silver lining, fair-weather friend). Is it raining? Then 'raining cats and dogs', 'come rain or shine', 'take a rain check'. Connecting the idioms to real weather makes them more memorable.

Common Student Errors

I am under weather today — I have a bad cold.
I am under the weather today — I have a bad cold.
WhyThe fixed idiom is 'under THE weather' (with 'the'). 'Under weather' is not natural English. The article 'the' is essential to the idiom and cannot be dropped.
She was on cloud ten when she heard about her promotion.
She was on cloud nine when she heard about her promotion.
WhyThe fixed idiom is 'on cloud NINE' specifically. The number cannot be changed. 'On cloud ten' or 'on cloud eight' are wrong — the idiom is fixed at nine. Always 'on cloud nine'.
It was raining dogs and cats heavily during our journey.
It was raining cats and dogs heavily during our journey.
WhyThe fixed order is 'cats and dogs' (cats first, dogs second). 'Dogs and cats' reverses the order and sounds wrong. Idioms are fixed in their exact wording, including the order of words. Always 'raining cats and dogs'.
The argument was just a storm in a cup of tea — nothing serious.
The argument was just a storm in a teacup — nothing serious.
WhyThe fixed idiom is 'a storm in a TEACUP' (one word — teacup), not 'a storm in a cup of tea'. The compound noun 'teacup' is part of the fixed expression. Native speakers use teacup specifically.
My academic essay states: The economy weathered the storm of the recession through careful policy.
My academic essay states: The economy survived the recession through careful policy. / The economy recovered from the recession through careful policy.
Why'Weather the storm' is informal idiom — wrong for formal academic writing. Formal writing should use neutral language: survived, recovered, endured. Save idioms for casual contexts. Mixing register signals lack of formal-writing skills.

Check Your Understanding — Part 1

A teacher feels slightly ill — she has a sore throat and a small headache. She wants to tell the school in a polite way.
Pick the most appropriate word:
A student has just received excellent exam results — the best she has ever had. She feels extremely happy.
Pick the most appropriate word:
Two friends had a small disagreement that everyone thought was very serious, but the next day they were friends again. The fuss was about nothing.

Pick the most appropriate word:
A grandfather walks five kilometres every morning to the market and back, regardless of whether it is sunny, rainy, or windy.
Pick the most appropriate word:
0 / 5 answered

Check Your Understanding — Part 2: Why Is It Wrong?

Each sentence has a problem with a weather idiom. Suggest a better version and explain.

I am feeling under weather today and may need to go home early from work.
Write the correct sentence:
Explain why it is wrong:
I am feeling under the weather today and may need to go home early from work.
The fixed idiom is 'under THE weather' (with 'the'). 'Under weather' is not English. The article 'the' is essential to the idiom and cannot be dropped. Always include 'the'.
After winning the competition, she was on cloud ten for the whole week.
Write the correct sentence:
Explain why it is wrong:
After winning the competition, she was on cloud nine for the whole week.
The fixed idiom is 'on cloud NINE' specifically. The number cannot be changed to ten or eight or any other number. The idiom is fixed at nine — possibly because in some old systems clouds were numbered, with nine being the highest. Whatever the origin, the form is fixed.
My academic research paper discusses how the economy weathered the storm of the global recession.
Write the correct sentence:
Explain why it is wrong:
My academic research paper discusses how the economy survived the global recession. / My academic research paper discusses how the economy endured the global recession.
'Weather the storm' is informal idiom — wrong for academic research papers. Formal writing should use neutral language: survived, endured, withstood. Save idioms for casual contexts.
He is a fair weather friend — he only appears when there are no problems.
Write the correct sentence:
Explain why it is wrong:
He is a fair-weather friend — he only appears when there are no problems.
The fixed idiom uses a hyphen: 'fair-weather' (with hyphen) modifies the noun 'friend'. Without the hyphen, 'fair weather friend' looks like three separate words and is non-standard. The hyphen joins fair and weather into one compound adjective.

0 / 5 done
1

STEP 1 — Weather and idioms (5 min): Write 'under the weather' on the board. Ask: what does it mean? Discuss. Establish that weather idioms use weather words for non-literal meanings. Show three more: on cloud nine, raining cats and dogs, a storm in a teacup. Each has a fixed meaning unrelated to literal weather.

2

STEP 2 — Feeling idioms (6 min): Drill the feeling idioms — under the weather (ill), on cloud nine (very happy), in a black mood (angry). Discuss the connection between weather and feelings. Sunny = happy, cloudy = sad, stormy = angry. The connection helps memory.

3

STEP 3 — Problem and storm idioms (7 min): Drill the problem idioms — raining cats and dogs (heavy rain), a storm in a teacup (small fuss), weather the storm (survive difficulty), take by storm (sudden success). Storms are dramatic — the idioms describe dramatic situations.

4

STEP 4 — Relationship and commitment idioms (7 min): Drill fair-weather friend (only in good times), come rain or shine (no matter what), steal someone's thunder (take attention), take a rain check (postpone). Each describes a social or commitment situation.

5

STEP 5 — Match idiom to situation (5 min): Give five situations. Someone slightly ill (under the weather). Someone very happy (on cloud nine). A small fuss (storm in a teacup). A friend only in good times (fair-weather friend). A walk every day regardless of weather (come rain or shine). Discuss as a class.

2 Match idiom to meaning (oral)
Read out a weather idiom. Students give the meaning. Then read out a meaning — students give the idiom. Both directions help fix the connections in memory.
Example sentences
Teacher: 'under the weather' → Student: 'feeling slightly ill'
Teacher: 'mean very happy' → Student: 'on cloud nine'
Teacher: 'a storm in a teacup' → Student: 'a fuss about something small'
Teacher: 'mean a friend only in good times' → Student: 'a fair-weather friend'
3 Weather idioms in stories (reading)
Give students a short story or paragraph using several weather idioms in context. Students must identify each idiom and explain what it means. The exercise drills recognition.
Example sentences
Sample story: 'Last week was difficult for our family. My grandfather was under the weather with a bad cough, my mother had a stressful project at work, and the weather was raining cats and dogs every day. Then my brother announced he was getting married — it was such happy news that we were all on cloud nine. The next morning, my brother told us his fiancee had a fair-weather friend who would not come to the wedding because of the bad weather. We laughed — what a storm in a teacup over nothing! Come rain or shine, my brother said, the wedding would happen.'
Idioms: under the weather (ill), raining cats and dogs (heavy rain), on cloud nine (very happy), fair-weather friend (only good times), a storm in a teacup (small fuss), come rain or shine (no matter what).

Plan Your Next Steps

For each strategy, choose the option that best describes where you are now.

Continue building idioms by topic. Other useful groups: COLOUR idioms (in the red, green with envy, off colour, see red), NUMBER idioms (at sixes and sevens, two-faced, on cloud nine — overlap), TIME idioms (in the nick of time, against the clock, time flies).
Connect to the four other idiom lessons — body (#45), animal (#50), food (#55), money (#59), and now weather (#65). Five strong topic-based foundations.
Look at how weather idioms appear in songs and films. Real-world examples motivate students because idioms are everywhere in entertainment.
Teach idiom register more carefully. Most weather idioms are informal. Some have formal alternatives (under the weather → feeling unwell; weather the storm → survive a crisis). Match the register to the context.
Ask students to keep an idiom journal organised by topic. Each new idiom they meet, they note with meaning, example, and topic group. Reviewing weekly fixes the idioms in memory.
What is the one change you will make next time you teach this vocabulary?
