Particle question about で and に


Can someone say:

"ここに暑いですね?"

To ask: "Its hot in here, isn't it?" Or is the correct way to say it:

"ここで暑いですね？"




The usual thing to say would just be

暑いですね。

But if you to want to use ここ, I would say

ここは暑いですね。

ここが is also grammatically correct, though the emphasis is different. Neither に
or で are appropriate here. に is typically used for a directional noun (though
it is also used with things you might not think of direction, such as 住む), and
で is usually used for where an action happens (well, it has other uses as
well). Here there's no action happening, or a direction for it to happen in.

If you want to say "in here" (as in, in this room) rather than just here
(which is all ここ means) you might say

このなかは暑いですね。 or このへやは暑いですね。
