Although / While

[peptidoglycan]

1) Although the temperature reaches 90 or 95 degrees in the daytime, the nights are often chilly.

2) While the temperature reaches 90 or 95 degrees in the daytime, the nights are often chilly.

The Elements of Style by W.Strunk says that this use of while is unfortunate. Because (2) can be paraphrased as

The temperature reaches 90 or 95 degrees in the daytime; at the same time the nights are often chilly.

and shows why this use of while is unfortunate.

What do you think about this matter?

 

[ceznaldo]

I think in everyday speaking either will do, in fact in spoken English you will probably hear the word 'while' used a lot more in this context as it gives the narrative a more flowing feel.
However Mr Strunk may well be grammatically correct.
By the way I love the idea of an opinion being 'unfortunate'.

 

[panjandrum]

This probably comes down to a question of personal choice.
I prefer to avoid using "while" if there is no specific sense of "during the time that".

 

[AMETAL]

I think although is more suıtable for the sentence you gave as an example.
When seeing 'While' I feel as if there was a process.
Altough indicates an contrast 'hot' and 'cold.'

While the temperature reaches 90 or 95 degrees in the daytime, nobody goes out.

This sentence looks more sensible .

“While” doesn’t work in this sentence though, AMETAL; you would have to change ‘reaches’ for ‘is at’.
