Yeah... good catch about the humidity...
It's something that you should be okay with. As a general rule, expect 90+ degree days with nearly 90% humidity
It is not a dry heat down here..... it's a nice sloppy moist heat that sticks around with ya all day long.... and only reluctantly lets go after a shower and some time in the AC.
The flip side of that is that fishing & gardening are great year round.
