We do this.
Actually, we apply a ton of science to this to avoid the AC because we are frugal. I grew up in KS heat w/o AC, so we learned REALLY well how to do it!
You use the North/South theory!
The sun is more to the south than the north, so you put fans in the North and blow in- as many windows as possible- in the morning and at night. As the day heats up, you reverse the ones in the upstairs and blow in from the north on the lower windows only. You continue to blow out the upper windows.
IF the air is cooler outside than in, you blow in upstairs at night, and have windows blowing out in another room upstairs to create a cross-breeze.
This keeps waaaaaaaaay cooler.
Best of all choices is an attic fan, the kind you mount in the ceiling and blow out with massive pull to the lower levels. Those are the best! You open the North lower windows and it makes a huge difference!
ETA: At our house, the A/C comes on when it won't go below 85* at night no matter what we do...then the arguing starts, because we can't agree over whether it's acceptable to leave the AC on and keep it on, or whether to open it up at night. The issue is that we had a friend in the HVAC business say it's bad to open it up because we have swampy humidity here, and at least the first hour the AC is on everyday will be removing the humidity from the air...and I'm not even sure if hubby and I fight the same point each year...sometimes I think we switch sides just to argue.
