My reliable source is a sticker that Onan puts right on the generator door.
As to the original question, you won't know for sure until you get there. Many times, in the desert SW the temp goes WAY down as the sun sets and you might be able to turn it off around midnight. I do that even in the SE where the humidity stays high at night.
My Onan has the same sticker. I did run it for a few minutes while troubleshooting a problem that turned out to be a broken ground wire at the genset.
