nice of you to think that by evening you get cooler air :D we have had days where the only time of the day where the outside temp was lower than indoor's was between 01-07. So either you stay up to open the windows, or wait till early morning... but then you just get 1-2 hrs before having to close everything again

Yeah, anecdotally night time temperatures have gotten much worse the last decade. But in the 90s-2010s you could easily get by without air-conditioning and no misery, with just passive temperature control.

  If you live in a brick/stone hours you can still go a long way by maximally ventilating house at nigh and during the day keeping sun out (shutters, awning e.t.c) and keep ventilation minimal. It would not help if the nights are warm (so you'd need AC) but there are still many more days with cold nights and by using shutters and timed ventilation you can reduce AC energy use. AC full on without other measures and passive thermal control techniques are no only two available options, one can combine them.

    Many years ago I lived in a brick apartment and the afternoon/evening sun would hit the wall next to my bedroom, making it very hot at night. I started going out with buckets of water to splash on the wall a few times each evening and it made a real difference. A white sheet hung across the wall might have helped more. Lots of things can be done if you don’t mind looking silly :) Unless you’re in the an area with high temp and high humidity. That is bad.

      Retractable awnings are very common including in residential setups in southern Europe.

        Do those also cover the apartment walls? I've only seen large awnings covering walls in detached houses, and even then it's relatively rare to cover walls that aren't close to doors.

        Usually no, most of the times the walls that have the longest sun exposure have terraces/balconies and awnings.

In addition, in some places (where I live) the air quality is extremely poor for much of the summer due to wildfire smoke. So even if you do get a cool night, if you don't have AC you have to choose between maintaining some level of air quality indoors or cooling your house.
