Do u need air conditioner in hotel mid Sept?
 

Also we are going in mid September, do you think I will need air conditioner in the room or is it cool enough by that time of year?

Where? Iceland probably not
Denmark probably not
Italy probably
Greece probably

sorry about that - Paris France - air or no air?

Air. Preferably chilled. Paris in mid September can still be warm and humid; so I wouldn't take a chance, especially if you want to sleep with the windows closed.

Air conditioning is a good idea from May to October in Paris. You'll definitely need it in the summer months, but in recent years even cooler months can be in the 90s F, so air conditioning is a wise precaution.

One experience. Paris (France not Texas). September. Open windows for cool air. Courtyard room. Aural entertainment. We both laughed so hard that a woman could fake it that loud. ( See Harry met Sally for reference )

Hi bg,

Will you be able to sleep if the room is 80F and humid at 11:00 PM?

There is another aspect to having air conditioning in Paris that most people don't mention, namely: keeping the noise out by shutting the windows.

We get a room with air conditioning. That way, we can shut out much of the noise from the street because the windows are double paned.

Paris can be warm and humid that time of year. Rain is frequent, and the buildings are heat traps.
The days are long enough that solar radiation warms the concrete and masonry and the heat dissapates slowly over time.

We were in a hotel room where the rain was coming in the windows. We of course had to shut them, or have a wet bed.
The temperature was not that bad in terms of raw figures - 80 F about - but after factoring in the high humidity and no air movement, the room was most uncomfortable similar to the description above.

Next trip, we had air conditioned quarters.

Dissipate.
I can so spell it. I just type funny.

Was it just two years ago that all those people died of the heat in France? I'm guessing it could be on the warm side.
