I live is So. Cal. - 6 miles from the Mexican Border, love the temperature but the prices can be a pain. But I used to it after 38 years. My sister just moved up to Camano Island in Washington State from Rialto CA. You have the 4 seasons, it can be a culture shock, but we were raised in Edmonds WA so she knew what she was getting into. They have a lot more rain, but people are still out and about because for the most part it is gentle rain. I would recommend a prolonged visit before actually moving there. The gray can really depress a lot of people.
They have state sales tax and property taxes (no Prop 13 though) but no state income taxes.
I have never lived in Oregon, near the coast, it is beautiful and they do not have the sales tax. Also, they pump your gas, no extra charge compared to what we pay in San Diego.
Good luck!
