I run misters in my cedar tree about 5' above ground and are 5 feet apart. I operate only above 95 degrees. The girls choose their places as it does cool (effectiveness depends on humidity). The misters in the run are 6' above ground and I use three in a distance of about 35'. Again, they stand where they want to. The misters (Ocean Breeze) use about 1/2 gal per hour each.
I also set three misters to run softened water on the A/C coils, one on each side, when temps are above 90-95 degrees. The increase in A/C coil efficiency is clearly noticeable as the unit cycles on for less time, less often. Electrical savings and comfort far exceed the water cost for the few hours each day. Saw it in last year's electric bill as it was significantly less and the summer temps were hot, hot, hot.
Mine also have swim pools as seen in the background...they use them. I change water every couple of days as a rule.

Wind is not a problem here, most always always plenty of it.
