I thought this would be a fun thread. We had something like this in my old DDC in 2009.
I live in Olympia Washington. The weather in late August/early September is the best of the year. Guaranteed dry and sunny, about 70-80 during the day and getting cooler at night (50-60). The blackberries are out all over and the gardens and farmers market bursting with fruits and veggies. It's my favorite time of the year here in this land of short summers. Also her birthday parties can always be outdoors! I always want to do outside parties for DD but the weather is not reliable in April here.
The only thing I'm sad about is I'll only have at the most 6 weeks to get outside with my new baby until the horrible rainy season starts. It usually stops being sunny and the gray and wet start around mid October. With DD being born in April at least I had all summer to be out with her. Oh well, better than a mid winter EDD!
