For some non-AC options if you don’t manage to get one in time: Those little spray fans that also mist you with water are remarkably effective. They usually are battery-powered, so still useful in a power outage.
Also, drinking cold smoothies is surprisingly cooling—probably any consumption of ice-cold water/stuff will get you a similar effect. I drank many of them to get through heat waves in San Francisco.

A fan and some improvisation (and old socks, plastic box, wooden spoon etc) works as a swamp cooler.
