During the late fall, when the water is still near 50F and the interior drops into the teens, we can have far larger temperature differences.
But proximity to water is only one cause of temperature variations. The urban centers tend to be warmer (the heat island effect) due to the release of heat by concrete and the multitude of heat sources in a city.
And then there are terrain effects. Cool air tends to flow into valleys and low spots, and thus they are cooler...sometimes by 5-8 F compared to surround hills or ridges. If you have a car thermometer you can see this effect as you drive. Or if you are crazy like me, you might walk around a hilly neighborhood with a digital thermometer.
You see why TV weathercasters show multiple temperatures on the news--they have to---temperatures are too variable around here.
What about daytime high temperatures? Here are the temps at 3 PM this afternoon.

You got to love living in an area whether you can choose your climate with a few mile drive.
Of course, there are even smaller-scale microclimates: the differences between an eastward or westward facing slope, north or south side of your home, shady versus sunny plots, and more. I learned from experience where I should not plant my tomatoes.
Friday, September 30th, I will participate in a meet-and-greet with two excellent Seattle School board candidates: Marty McLaren and Sharon Peaslee at Puget Ridge Cohousing Assn, 7020 18th SW (north of SW Myrtle) from 6-8 p.m. Refreshments of course.
Dog Update: My little cockapoo is still on the loose...if you are in Seattle and see her (see below), let me know...thanks...cliff
