Haven't been online much over the weekend, so just seeing this now. I am steadfast in my choice that has come up in other threads over the years: northern California, specifically The Sea Ranch in northwest Sonoma County, three hours north of San Francisco. It's never been warmer than the low 90s (and that's exceedingly rare), it's never humid when it does get warm, and it rarely gets below 32 in the winter (no snow, no ice). There's not a lot for jobs since it's a relatively isolated vacation area and it's expensive, but we'd figure out a way to make it work. If the means presented themselves tomorrow, I'd be there for the rest of my life. The video below shows just a small portion at the south end of the community.
Edited to add current weather at The Sea Ranch as of 10:17 a.m. Pacific time today: sunny, 61 (feels like 57), dewpoint 47, winds NW @16mph. Forecast high of 64, overnight low of 48. Extended forecast through next Wednesday: highs between 67 and71, lows between 49 and 51, with sunshine every day.
