The weather is hot today, right?

There is nothing wrong with sentence grammar, but it is illogical.

In English, we say weather is fine/good/bad, etc.

(The weather is good, not good, ...)

Generally, we don't say "the weather is hot"

But you can say It's hot today.

as for the new concept sentences,

"the weather's cold in the north and windy in the east"

the first sentence is changed to

"it is cold in the north and windy in the east"

comparative logic

the second sentence

"our cl". Imagine is not very good, but it's surely interesting "

There is nothing wrong, it's absolutely right.
