Maybe if the blinds are on the outside of the window, but IME that’s not the norm north of the alps. And you can’t blind+fan your way out of 40°C heatwaves, the nights get warm too and then you can’t properly cool down your place at night anymore.
True, but we’re at the time of year when there’s way more daylight than night, so it’s a war of attrition with the hot day winning no matter what you do.
Not sure how true that is, although I don’t understand how, one side of my house is noticeably cooler than the rest and it has stayed like that throughout the heatwave even without turning on the ac

If it’s a couple days maybe, but in a heatwave everything will heat up eventually.
you can open windows during night, as long as night air temperature is tolerable
Night air in a 40°C heatwave isn’t going to be particularly cold, especially when you just passed the longest day in the year.

That’s your lower bound, but you need to have fans everywhere to replace all air and cool down your walls to the air temperature.

Is it the North side? Maybe painted a different color?
maybe you have some kind of natural evaporative heatsink nearby (trees) or perhaps inside
Can’t confirm. Especially if you live directly below a roof.
