I have a window fan in the bedroom, which has been doing quite well--it has a thermostat, so it'll stop on its own some time between two and four, depending on how fast it cools down.

I'm facing the wrong way for the breeze, and it's a one-room-wide apt., shaped like a trailer, so the only other window is the sliding glass door on the balcony at the other end. That door is now open, and there's a fan going in front of it, as well, but I'll close it and turn off the fan before I go to sleep, usually. I get up early enough to have it run again in the morning before the heat hits that side.

According to the fan readout, it's 79 in here now, so I'm doing all right. Still not looking forward to another couple of days of this. I was going to sew...
