Sorry about the wrong spelling in my previous post. I meant to ask which sentence is correct: 'The weather is cold but there is fresh aire' or 'the weather is cold but there is fresh breeze'?
Neither is quite right.
The weather is cold and there is a fresh breeze
would make most sense. If you need to use "but", then this would make sense:
The weather is hot but there is a fresh breeze.
"Fresh air" won't work in this context.
