We can argue about whether or not it pissed down all the time, but here in London we have definitely had a wetter than usual summer.
My job involves cutting grass, lots of cutting grass, and during most summers there is an extended period without rain which allows the ground to dry out so that the grass slows down and even stops growing for a while, allowing us to do other stuff. This hasn't happened at all this year.
You could even say that summer has been cancelled this year, rather than Christmas...
