Idiom of The Day – Under the Weather Meaning & Examples

Welcome to our daily Idiom series, designed to help you sound like a native American English speaker. Today’s idiom is “Under the Weather.” In this post, you will learn what it means, where it comes from, how to use it in real sentences, and which common mistakes to avoid.

Idiom Under the Weather Meaning

Let me share a little story. A few months ago, I was really looking forward to my best friend’s wedding. I had bought a new dress, planned my hairstyle, and picked out the perfect shoes. But just two days before the big day, I caught a bad cold. My nose was blocked, my head felt heavy, and I had absolutely no energy. When my friend called to check on me, I said: “I am feeling a bit under the weather.”

Of course, I was not standing outside in the rain. The phrase “under the weather” simply means feeling sick, unwell, or not quite yourself. It is a softer, more natural way to say you are ill — and native English speakers use it all the time.

So the next time you are not feeling well, instead of just saying “I am sick,” try saying “I am feeling a bit under the weather.” It sounds more natural and is far more commonly used in everyday American and British English.

Similar Idioms with Meaning

Tip: “Under the weather” and “off-colour” are both mild ways to say you are unwell. “Sick as a dog” is much stronger — use it when someone is seriously ill.

Common Mistakes to Avoid

The first mistake is using this idiom for situations that are not related to health. “Under the weather” is only used to describe illness or physical unwellness. It cannot be used for nervousness, lack of preparation, or bad mood.

The second mistake is connecting the idiom to actual weather. Just because the word “weather” appears in the phrase does not mean it describes rain or storms. The idiom is entirely about health, not climate.

The third mistake is altering the wording. Common errors include “below the weather,” “under weather” (missing “the”), and “under the weathers” (wrong plural). The phrase is fixed — it is always “under the weather,” exactly as written.

Practice & Application: Using “Under the Weather” in Speaking (IELTS & Real Life)

“Under the weather” is one of the most practical idioms for IELTS Speaking because health and daily routine are very common topics in Part 1. It also works naturally in Part 2 when describing a time you had to cancel plans or deal with illness. Using it confidently and correctly shows the examiner that your English vocabulary is natural and not just textbook-perfect.

IELTS Speaking Practice

Part 1 — Short Answer

Question: Have you ever had to cancel plans because you were not feeling well?

Sample Answer:

Yes, quite recently actually. I had been looking forward to a cousin’s birthday dinner for weeks, but on the day itself I woke up feeling under the weather — sore throat, mild fever, and no energy at all. I had to call and apologise, which I felt terrible about. My family was understanding, but it was still disappointing. I ended up resting the whole day and thankfully recovered quickly.

Part 2 — Cue Card

Describe a time when you were ill and had to miss something important.

Sample Answer:

I would like to talk about a time I was under the weather right before an important college presentation. My group and I had been preparing for weeks, and we were all quite nervous but also excited. Then, two days before the presentation, I came down with a severe cold. I was completely under the weather — runny nose, constant sneezing, and a headache that made it hard to concentrate. I still attended the presentation because I did not want to let my group down, but it was one of the hardest things I have done. I could barely speak clearly, and I had to pause several times. Looking back, I think I should have rested more in the days leading up to it rather than pushing through the late nights. The experience taught me that taking care of your health is not a luxury — it is what allows you to perform well in everything else.

Part 3 — Discussion

Question: Why do some people continue working even when they are ill?

Sample Answer:

There are several reasons. In many work cultures, especially competitive ones, people feel a pressure to show that they are dedicated — taking a sick day might be seen as weakness or laziness, even when someone is genuinely under the weather. There is also the practical concern of deadlines and responsibilities. If you are part of a team, falling ill at a critical moment can feel like letting others down. However, I think this attitude is slowly changing. More employers now understand that a person who forces themselves to work while unwell tends to be less productive and takes longer to recover, which costs more in the long run.

Question: How important is it to rest when you are feeling unwell?

Sample Answer:

It is extremely important, and I think it is something many people underestimate. When you are under the weather, your body is working hard to fight off whatever is making you ill. Pushing through without adequate rest is essentially taking energy away from that recovery process. Short-term rest almost always leads to faster recovery than trying to carry on as usual. Beyond the physical benefits, rest also protects the people around you — if you are contagious and you go to work or school, you risk spreading the illness to others. I believe resting when ill is not just self-care but also a form of consideration for others.
