Lots of water will be key. Also, I've heard that some people in warmer climates grow their hostas in pots, since it's easier to maintain the potting medium/soil.

Several hostas perform better than most in the heat, whether because of family history (the fragrant ones) or thicker leaves. Starting there, you get plantaginea, Guacamole, Avocado, Holy Mole, Paradigm, Sun Power, Sum and Substance, and a lot of their sports or offspring.

Personally, I've also had success with some of the skinnier hostas that also have some substance, like The Razor's Edge and Pineapple Poll. I grow those in sun here, which is probably equivalent to your shade down there. The tips can bleach a little, but the plants seem to do fine otherwise.

Last but not least, Undulata Albomarginata is an old hosta that survives better than most in the heat even though it has thin leaves; it won't always look good but will keep coming back. It's also cheap, so you can find some volunteer victims really easy.
