For Mississippi alligators at least, while the determining factor for sex is temperature, this is likely more a proxy for birth location than it is climate or weather patterns. If the nest is on leaves, then the egg temperature is about 34 C, and if its in a marsh, then the egg temperature is 30 C, meaning the leaf nests produce males and the marsh nests produce females.
