Hello there and welcome to BYC! 
I can't say for sure RIRs will thrive in your environment however we certainly have tons of humid swampy air on this side of the world and they do just fine.
Definitely cover your cement with something for padding the hard surface and to absorb poop. Either sand, (purchased or harvested from nature in a clean area) or possibly wood chips/mulch. Either of these will tolerate wet humid weather if you turn it over occasionally.
Good luck and welcome to our roost!
