Other forms: weathering, weathered, weathers
The weather is what the sky is doing today. Bad weather, the weather forecast, under the weather.
It is the state of the atmosphere now, where climate is the long-run pattern — a distinction worth keeping clear. Britain's is famously changeable because the country sits where several air masses meet, which is also why the subject is so useful for conversation. Note under the weather, meaning slightly ill; weather a storm, meaning to survive it; and weathered, meaning worn by exposure.

Too few real examples of this word to estimate which sense is commonest.
