Good advice. I did this Wednesday, unfortunately the wall in question is the longest in the house, and gets blasted with all of the afternoon sun. even after 2/3 minutes of cold water on the bricks the water was still warm by the time it reached the bottom of the wall. I think its the dark tiles on the roof that make it the worst though.
If you can spray water on the outside walls, the paths near the house and the garden. The evaporative cooling of the area will help a bit.
@Seagoon_ @TinyBreak very sage advice.
