The calendar says summer, the thermometer disagrees

This is the weirdest summer ever. Last year we were sizzling in the hottest heat wave since records had been kept. This year, August temps are only in the 70s and 80s range. I suspected the cooler weather would only last a few days, but it has lasted a few weeks and the forecast shows no change. I have never in my life experienced a summer this cool. It feels weird, and wearing summer clothes is out of the question. In August. I don't know how to act.

I know the weather was cooler in America some this summer too. What's going on?

Chinese people find it amusing that foreigners (that's us) always want to talk about the weather. But I just do, I can't help it.
