It's the new Labor Day Tradition around Seattle: Celebrate Bumbershoot, get in those last second Back to School deals, and complain about how lousy the summer weather has been :)

Between last year and this year, it's been a very vocal topic when it comes to the weather: "Man, this summer has been dismal!"

I wrote a story last year documenting that the summer of 2007 wasn't too far off of normal, it just felt cool compared to recent sunny and warmer summers.

Then came this year, which began with the coldest start to June ever.  July was pretty nice and were doing OK into mid-August before the cool rains returned.

But has this summer really been that bad?

Hoping to answer the question once and for all, and to have something to gauge future summers, I've put together what I'm tentatively calling the "Summer Sanity Index" although I am open to suggestions for a better name. (Submit yours in the commenting fields below.)

I went back all the way to 1948 and then for each year, compiled the average high temperature between June 1 and August 31 -- the basic time of summer vacations. (Not counting September since kids are back in school and summer is for all intents and purposes over, even though technically it has three weeks left.)

I then rated them on a scale of 0 to 100 -- 50 being an average summer for temperature, 0 being the coldest on record, and 100 being the warmest on record.

To balance this a bit, I then did the same for number of days in that period we had measurable rain -- figuring that is a better gauge than just using aggregate rainfall totals since that could get skewed by a big storm.

(For example, if you had one day of heavy rain but 29 days of sunshine, people would generally accept that is a nicer summer than to have 10 days of lighter rain that added up to less.)

And again, I ranked each year based on 50 being normal, 100 being the least rainy and 0 being the most frequently rainy.  I then averaged the rain and temperature scores together for a final score.

(I wanted to also use number of cloudy days vs. average, but that data is very difficult to find earlier than the mid 1990s -- it's all hard copy buried in some warehouse in D.C.)

So what did I find?

Our recent summers have nothing on 1954, which rates by far the "worst" summer ever. (Yes, I know rain fans, this would be the "best" by your standards, but for ease of writing, we'll go with sunny and warm being what's expected in summer.)  That year was the coldest summer -- with just an average high temperature of 66.23 degrees through the summer. It was also the most frequently rainy with rain on 32 of the 92 days.  It gets a Summer Sanity Index of "0".

The best summer? 1967.  That was the third warmest summer on record -- 77.48 degrees and good for "99" on the index, and just behind the 77.62 degree summer of 1961. But 1967 was the driest with just 6 rainy days that summer to give it a near perfect Summer Sanity Index of 99.5.

So what about this summer? It was just a little below average, scoring 45.5 on the Index. The average temperature was 72.09 degrees, good for a score of 45 compared to the "50" score of 72.60.  We had 20 rainy days, just over the '50' score of 19 average rainy days.

And believe it or not, this past summer actually rated a little worse than 2007, which finished with a score of 46.5. (62 on temperature, but only a 31 on rain).  The 2006 summer, which everyone remembers for being sunny and warm, rated very well, scoring a 70 -- the 10th highest score.
