If you want Arizona, try Yuma. Lots of snowbirds there.
It's been 40 years, but I spent several days in Yuma. Not my idea of a great retirement area, but it so depends upon what you want. No idea about tennis either. At least it would be warmer. I did some ag research in lettuce and cotton fields there. In the February mornings, there were icicles hanging from the irrigation sprayers but by afternoon it was low 80s. YMMV
