This is a fallacy I see thrown around a lot here. An average summer feels "like summer" here because that's what we are used to. If there was someone who was a "heat lover", who thought that summer should be constant 90+ degree days like they have in Texas, then they would be pretty upset about how "un-summer like" the typical summer is around here. They might make the same argument that beavis made and say that "the heatwave back in June was the only 2 weeks of real summer we've had. The other weeks have only been a disgrace". In fact, they may be used to the winters we get in the Midwest and say "90% of days in the winter feel like winter! In January and February it's winter-like because the calendar says so. Why can't summers do that here?"
If we set our expectations for something that just doesn't happen climatologically, then we will get disappointed. Every single year. The only solutions are to A. move to Phoenix/Houston or Mt. Rainier/Alaska or B. Accept normal, and enjoy a nice 60 degree winter day when it comes (go outside maybe?).
