This is all the usual advice, which works for a few days, but during a period of over a week of high temperatures, there's nothing you can do.

The sun will eventually heat up every part of the house and turn it into a radiator.

Even when night time temperatures drop to 17c, I have my have windows open at 10pm with a decent cross-wind, my bedroom temperature may drop from 26c to 24c after 2-3 hours, but if I close the windows, it jumps to 25c in ~30 minutes...

The streets probably don't help either - no trees, just asphalt, front yards with paving slabs etc

That's pretty nice actually!

I am in a brand new rooftop apartment, so pretty exposed to heat. I can keep 28-29C indoors when it's 38C outdoors. That's hot but workable with a ceiling fan.

At night we open all windows and have a ceiling fan above the bed. We've got about 24C indoor in the morning, with nightime outdoor temperature at about 21C.

Obviously I keep physical activity to early morning and late night.

17c outside just to be clear, highlighting that that it doesn't serve much purpose in cooling inside the house

We also have high humidity which makes 25c to 30c at night very uncomfortable for us Brits.

People often forget about humidity when telling people they don't need AC

And you have to remember we're a country of people used to max summer heat mostly being around 20-22c and many people will sleep with the window partly open in the depths of winter

> People often forget about humidity when telling people they don't need AC

True that it is not so humid here in the French alps.

But to be clear: do get an AC if you need to. Please dont rely only on your AC though. Turning on the AC (eg just pressing a button, really) is so easy we tend to forget about the rest... and end up burning even more fuel.

Scotland here - have heard people from London talking about moving here for the weather.. which isn't something I ever expected to hear!

Was 10C this morning when I went out to walk my dog, in a t-shirt and shorts!

I hope you didn't get heatstroke ! XD

I'm surprised you need to put clothes on your dog
