Full origin of under the weather →Frequently asked questions
What does 'under the weather' mean exactly?
It means mildly unwell: a cold, a headache, general tiredness. It signals something minor and temporary, so it would be odd to use it about a serious illness such as pneumonia.
Where does the phrase 'under the weather' come from?
It is widely associated with sailing, where a seasick or ailing passenger would go below deck and out of the weather. The nautical link is plausible and often repeated, but the exact origin is not documented with certainty.
Is it polite to say you are under the weather at work?
Yes, and that is much of its usefulness. It excuses you without requiring you to describe symptoms, which is why it is so common in emails to a manager or a client.
