it seems something like 80% of this year are taken up by weather complaints of one kind or another

Why do I need a blanket to huddle under at the end of June? We had a couple of warm days a while ago, but then it got colder again. It's not that I want extreme heat, but lows of 9°C and highs of 14°C are not the temperature range you think of for "summer". Why can't we have a nice 22°-25°?
