San Diego if you have enough money to live away from the city itself and send maids into town for groceries. It's like 78 - 80 degrees all the time.
Florida is very hot and humid.
Hawaii is very expensive because of where it is. Many people come back to the mainland so it can't be all that great once you live there for a while.
Be very wary of places that are isolated because without job competition employers are free to abuse you with lower wages and lots of responsibilities that they would be afraid to heap on you if you could just take your talents elsewhere. I know this living up in this resort destination. I'm self employed now and have to do everything. It just doesn't seem like abuse so much now.
This is paradise in the summer.
About 78 - 82 degrees with 10 percent humidity - and wildflowers everywhere. When you get older you appreciate this kind of thing. We came for the winters and stayed for the summers. (That's a saying here).
