Pushka have you considered an outdoor misting system to cool things down? I received a relayed message where the temperature dropped 7 degrees Celsius on a property one hour north of Adelaide in post code 5401. They had the verandah temperature drop from 31 to 24 and installed it after a 50 degree day and a 45 degree day.
You could get set for less than a hundred dollars.
