If it were me (and I've done over 900+ dives around Florida and dove in some of the really rarely dove, interesting spots -- so I can have a small opinion...
-but probably not as much an opinion as others who have dove Florida even more.....
)
In August I would book with Randy with Emerald Charters - Tequesta near Jupiter - book with ScubaWorks and hope the goliath grouper are aggregating and the currents will allow you to photo!
Then I would dive BHB that is fairly nearby with someone who knows the spot. It often takes a few days to "find" things there and you don't have days to kill. Since I had a couple of days to kill to just search and practice at BHB I located things I wanted to photo and then took a friend back with me. On one dive amongst lots of fish, etc. we found and photoed 2 striated frogfish, 2 longsnout seahorses, 5 pipefish of various species, a northern stargazer (the most handsome stargazer in the world in my humble opinion), 3 pairs of mating common octos including a pair that had been together for a week and it seems the "affair" had cooled somewhat.....
, several atlantic longarm octos out hunting (that's our version of the mimic octo), unusual small nudibranchs and a strange small seahare that rode on one of the seahorses and two species of searobins plus lots of baby fish. Not bad at all to practice macro!!!! This is a free dive with security in the park but you need to be out by sunset (no more night dives there). And the security is needed as one day we dove it we couldn't exit the park by our usual right turn (because the bridge was closed above the park because of a shooting) and we took the long scenic way around through Singer Island and the park. Don't have accomos near the bridge but the Phil Foster Park at BHB is safe itself now because of the security. I made friends with the rangers and they are pretty cool and watched me, etc.
Of course if there is a hurricane or tropical system all bets are off!!!
Good Luck! Carol
PS I wear a 5mm wetsuit there all year long including the bridge and Jupiter - but then that's how you get nice long dives now and limit air consumption isn't it?? By staying warm - but of course judge for yourself -- not toooo warm....
