Hot weather actually should be pretty good for fuel economy - less dense air doesn't mean anything for efficiency, it just means less power, since less air = less fuel needed = less power. But less fuel = more fuel efficient. But if it's too hot, now the AC is on, and you're putting a load on the engine.
It's why a short-ram intake should actually improve fuel economy at the expense of power (despite what they claim - probably because their dyno tests are done with an open hood).
