This. Water it deeper & less frequently, and cut it long. I schedule a watering night be split into two full cycles to reduce water running off down the street and increase absorption. If I want, for example, 10 minutes total per zone, I do zones 1-9 for 5 minutes each, then repeat the whole thing. I'm watering 2x a week and the only problems I'm having are in the spots with very few hours of shade to no shade at all.
Another thing that I've found has helped a ton this year is adjusting my sprinklers to make sure the water is being distributed as evenly as possible. I had my sprinkler system built 20 years ago, so what was left after we built the pool last year needed some work after 20 years of yard work, adding dirt, sodding here and there, women & kids in cars running over the sprinkler by the driveway, etc. We had to replace the back yard sprinkler, so that needed a lot of tweaking as well. This crazy heat has made it obvious exactly where the sprinklers needed work - where there was too little water, too much water, or it was just right. I'm not surly 1%, so I did most of that shit myself. It's a pita, and dirty work, but it's really paid off.
