I think you can, Sheri, I have known succulent growers in much more humid areas that grow them. but they do have to grow them in containers and make the media very porous, so the roots will dry out faster and be able to move them to protected space if it rains too much. Succulent tropicals like epiphyllums, plumerias, adeniums should do nicely in your area as long as in very well draining media. Just maybe steer away from the desert type succulents, those ones really want to be very dry, and in low humidity. Some succulents are dormant in summer, and some are more actively growing when temps are cooler.
