Can we use "as" in this manner?

It is very hot here in the summers. However it isn't as hot in the countryside.

or

It is very hot here in the summers. However in the countryside, it isn't as hot.

I've searched the web but only found sources using as...as for comparison. I think my sentences just convey the same meaning as

It is very hot here in the summers. However it isn't as hot in the countryside [as it is here]

where "as it is here" is implied.

edit

If I simply say "It isn't as hot in the countryside." without any context will it be fine?

I'm worried because I found some examples here where they're using the phrase without context.

Is the structure I'm trying to form not popular enough because all I can find on the web is as...as comparison?

Is it always necessary that 'as' has to be followed by 'as' while making comparisons?

Solution 1:

Yes, it's fine. The part in square brackets ([as it is in the city]) is only needed if you don't give the other person full context. However, in the course of a dialogue, you've likely already provided all the info they need so

Solution 2:

Yes. If you're looking for the classic construction, your phrase will look like this:

"It isn't as hot in the countryside as it is here in summers" (The "It is very hot here" is implied)
