So I live in inland Los Angeles area (west sanfernando valley), temps are supposed to hit 111 for the next 3 days and have been around 102 to 107 the last few days. I have the highest grade shade cloth that filters out as much sun as possible and still, my pots are real hot!, not the soil, but the pots. I cant just keep running water thru the soil, cause at best I will fungus problems and at worst, root rot from decaying killed off roots that touched the inside of the pot.
 What I do is i essentially use shop towels (Shop rags) that I get from left over surgical paks at the hospital I work at, I drape all the pots in towels. everything but the trees trunk is covered. Kind of a funny scene, if you blur your eyes and look at my garden, everything looks like its in sky blue pots. I then wet down the area around the trees, under the benches and even the shade cloth. I put just enough water on the trees surface to wet the towels.
 This method has worked well for me keeping the pots and soil cooler than the air by at 10 degrees. Sometimes a couple of degrees is the difference between life and death.
Yesterday my teacher paid me a nice compliment as we were sweating it out in his garage working on some trees. he said if I can keep trees alive in those conditions, i can keep them alive anywhere.
You can use used wash cloths or buy shop towels from an automotive supply place. Obviously, you wouldn't want to use used shop towels that have oil or other toxic solutions on them.

 This afternoon, at about 3:30, the hottest part of the day, I took my infrared temp gun and took some temps. The surface temp of ceramic pots with no towel draped over them (all under heavy shade cloth), was about 110. The pots with towels on them were in the low 90's under the towel. Then using a thermometer with a probe, the internal soil temp of trees with towels on the pot ranged in the upper 80's to low 90's. Trees with no towels had internal soil temps of at least 10 degrees more.
 I did not put towels on some trees cause they are completely raw stock in big containers.  I think without the towels, I for sure would lose some trees and a bunch get severely stressed.
 I would like to hear from people who live in desert areas that routinely deal with very hi temps and see how they have adapted.
