I feel like anywhere outside of the cold and wet belt around Arlington would be pretty ideal for him. Even people to the north usually report sunnier and drier conditions on the reg.
71F and mostly cloudy but dry.
If y'all want to put the patio furniture out earlier, then I suggest moving or getting a second home or time-share in the south Willamette Valley.
Much warmer and drier and no oppressive heat yet. It will get hot sometimes but nights are usually good.
