Quite a detailed and scientific explanation there!
I was about to say, in Seattle we get about 30 days of blue skies per year, and summer starts in mid July and ends in early September for us. The rest of the year is just a a long, extended mix of autumn and early spring with rain, clouds, and muck. Here we like to joke that the earliest summer starts for us is the 5th July, because in all previous years, even when summer has come early, the Fourth of July has always been cloudy for us. This year was the first year in about a decade where we were able to see fireworks unobscured by cloud or rain.
