I feel best by the ocean. Trips to Hawaii and the coastal Carolinas have been great short term success stories.
I live in WNY, and the best I've felt in over two years is AWAY from here!
I'm leaving in a week for 4 months in Myrtle Beach, SC. It should be interesting to see if there is improvement with a long stay "by the shore" in temperatures that will be getting steadily cooler than the temps during my brief positive experiences of Sept in Hawaii and April in NC an SC.
I also live in the Buffalo ny area and battling RA its been a awful this time. Have you ever heard of the Road Back Foundation check it out.
I don't know about states because I live in Europe, but I'm worse in wet weather and better in dry countries.
my father has pmr and visits my sister in New Mexico. It has a very dry heat he says that he feels better not completely but better than he does here in New York. I feel my worst on extremely humid days, I however have not been to NM since I've been diagnosed and I have ra, and that is different from pmr. He says that its not so much better that he would up and move his entire life out there just to feel some what better.
I think the climate cure for RA is a myth. But maybe you'd like to live where it was ideal. No snow to shovel and no oppressive heat. Let me know if you find it. Here in Fla. it is too hot to breathe some days, but the winter is nice. Extremes seem to be the thing to avoid, but that would be for comfort, not cure. Just my opinion.
