Elaine, check your local vendors. Santa Barbara Orchid Estates lists which Cyms. are "heat tolerant". I don't buy from them often , as they are pricey, but they do have some good info, considering their location, and my two Oldest Cyms. probably came from them. If you have a local Cym. grower they may be helpful. They grow them in Hawaii where they have to haul them up the mountain at night to get them to bloom. As long as they get the 20deg. change between day and night temps. most should do well in the south east.
