I finally looked up the hard stats so that I could prove a point. First, I looked up the Durham, NC stats which looked pretty good to me. Click through to Wikipedia for a bigger picture, but the basics are that it usually doesn't get too cold, rarely snows, has a good mix of sun and rain and provides enough heat in the summer that you can work up a thirst and find lemonade refreshing. All things quite important to me.
Probably the most convincing argument in my mind for San Francisco's non weather perfectness is the absence of seasons. Just pulling together this graphic to show how the above data plays out made me nostalgic for leaves in the yard, grass and dustings of snow.
For Mr. Palindrome's case, the 1374.6 hours of sunshine per year in Durham reinforce his case that San Francisco has much less rain and much more sun. The chart below for San Francisco's weather history shows very little rain, milder summers and winters and 3061.7 hours of sunshine per year.
What's your idea of perfect weather? Would you want to live year round in perfect weather? Do you and your partner have the same idea or different ideas about it?
