Calcify...
I was in Dubai in September and it was quite hot and VERY humid. Since you're from the states, imagine what a Miami humidity feels like and add about 30-40 percent on top of that. I was surprised. I had spent some time down in Miami and it has never been over about 37 (100F) in Miami. Dubai goes well above 37 AND has the humidity. Of course, you don't spend a lot of time outdoors then.
I suggest you take a "fact finding" trip/tour to Dubai at some point to check it out for yourself. I did this and found I really enjoyed Dubai, but I was there as a tourist and didn't have to live there on a day to day basis... but I still liked it.
Cheers
