Is Summer over?

The weather in Amsterdam is like a girl that can't decide what shoes to wear to a dinner date with her girlfriends....kind of psychotic. One minute the sun is full out, you take your scarf of and smile just like the sun...the next minute, your big umbrella comes out of your bag and people around you seem irritated that they forgot theirs. Is this just a tease that will end up in some after Summer sun or is this the beginning of fall?? Confused.
