I'm surprised that there seem to be no minimal of gardens on this thread. We're lucky enough to have a garden, and that it always has a shady spot somewhere, so we sit outside for much of the day, moving around. Yesterday and today we've had a cooling breeze, which is great! (We're in NW England but it's already 30°.)
Other cooling factors in our (small) garden are hedges and grass - we focus on supporting wildlife so some of the grass is uncut at present. (It remains pretty green.) We also have a small pond and a (freestanding, and unconnected with the pond) water feature, which sounds lovely and cool. (It's the sort which pours down through "bowls".). Perhaps this isn't for everyone but it's just some ideas!
I think you under estimate just how small many modern gardens are. 3m x 5m would encompass the size garden attached to many new houses, certainly in our neck of the woods.
We live in an old house in a town centre and have a bigger garden than average for our situation, and yes, part of the garden is in shade all day long, but we are surrounded by buildings, a converted mill and its car park behind us. The huge walls of tall old buildings on either side.
The temperature in our garden, even in the shade, has been far too hot to even contemplate, sitting out in, even when there has been a breeze. We have just hunkered down in doors with curtains and blinds drawn on the sunny side. We have fans on all day
I hope you are ok
