Weather vs Whether: How to Tell Them Apart
Weather is what the sky is doing. Whether introduces a choice between possibilities.
The weather turned. I asked whether she was coming.
The test that settles it
Try replacing the word with if. If the sentence still makes sense, you want whether. Weather is a thing you can look out of the window at, and nothing else will substitute for it.
“he asked ___ we agreed” → if we agreed works, so whether.
“the ___ has been dreadful” → if is nonsense, so weather.
Whether belongs to the question family — which, what, when, why — and every one of them opens with wh. A choice is a question, so it takes the wh spelling.
Weather: the state of the atmosphere
Rain, sun, wind and temperature. As a verb it means to come through something difficult, or to be worn away by exposure.
The weather closed in by midday.
They weathered the recession.

Could you point at the sky? Then weather.
Whether: introducing alternatives
A conjunction presenting two or more possibilities, often paired with or. It never names a thing; it only sets up a choice.
I do not know whether to laugh.
Whether or not you agree
It depends on whether they call.
Does if fit in its place? Then whether.
Side by side
| Weather | Whether |

| What the sky is doing | A choice between options |
| Noun and verb | Conjunction |
| You can see it | It introduces a clause |
| cold weather | whether or not |
The exceptions
A wether is a castrated ram. It is a real word, it appears in bellwether — the lead sheep with the bell, and hence any leading indicator — and it is spelt with neither the a nor the h.
So bellwether has nothing to do with forecasting, despite how often it is written bellweather.
Both can introduce an indirect question, but whether is required before or not, before an infinitive (whether to go), and after a preposition (the question of whether). Where either works, whether is the more formal.
Where people get it wrong
| Incorrect | Correct | Why |
|---|---|---|
| I am not sure weather to go. | I am not sure whether to go. | A choice. |
| The whether forecast is good. | The weather forecast is good. | The sky. |
| a bellweather for the wider market | a bellwether for the wider market | The sheep, not the sky. |
| They whethered the storm together. | They weathered the storm together. | The verb from weather. |

Frequently asked
Is whether or not ever redundant?
Sometimes. When you mean regardless, keep it. When whether alone carries the sense, the or not can go.
Do all three sound the same?
Broadly yes, though some speakers still aspirate the wh in whether.
