Yeah - we’ve always used the shutters to regulate the temperature inside - my mother has lived here thirty years. As you say, it’s when it starts to get cumulative that it stops working. The days have been touching 40, the nights 30 - I’ve been doing astronomy in shorts and a t-shirt - feels weird. The upshot is that at night, the walls radiate the day’s heat - normally, this is welcome, as it smooths out the daily temperature cycle (and provides an infrared lamp for cold astronomers) - but right now it’s just slowly getting hotter and hotter on the southern end of the house, as it’s absorbing more than it’s radiating.
And yeah, we stumble around in the dark and head out into the anvil of the sun. Even the insects have given up and shut up. Hot in the height of summer is normal here - but this is both early in the year, and those few degrees make a big difference at high humidity - above/below body temperature. I’ve been more comfortable than I am right now in 55 degrees in a desert, as in the bone-dry air, sweating works remarkably well, as long as you stay hydrated.
Are ceiling fans used in Europe or at least where you live. As it could be an opportunity for someone to import and sell ceiling fans in European cities where there is hot humid summer with no breeze suddenly as previously no market for them.
