I know you are probably sad to see the sunny days and summer temperatures fade away, but in terms of dating, you should start getting very excited for fall.
Summer for a lot of people is all about finding a fling, looking for a hookup, and taking advantage of the nice weather to go out and meet as many different people as possible. Once fall comes however, a lot of daters change their tune. The colder temperatures send the brain a message to begin building a nest and preparing for the winter. Fall is a time when singles want to find that person that they are going to snuggle up with when it snows, to watch a movie with, and to maybe even take home for Thanksgiving dinner.
