Scuba Jenny is great
Sorry that someone up north let this mean weather out the barn gate.
Looking at the forecast I'm not sure you'll be able to get out...or if you do that it will be much fun in high seas.
When the seas are this wavy, if you do choose to go out, go on the biggest boats that are the most stable: Ocean Divers, Conch Republic, Horizon Divers, Rainbow Reef all have large stable boats.
If these boats do go out, they may limit to experienced divers.
Here is the current forecast (remember it is a prediction and could be off by a bit and is always being re-forecasted):
Personally I don't take students/guides in seas greater than 3-5ft as it's just not safe on the surface, getting off and back on the boat, and the ride isn't much fun.
There are 2 alternatives, not as pretty as our coral reefs, but both protected from winds and high seas.
1-Pennekamp Park Cannon Beach - 18ft max, silty laid out easy to navigate viz around 15ft. There are 1715 canons and a wall of little critters. We've seen some surprises there too - manatee, dolphin, nurse shark, sting ray. Admission is cheap by the car load. You will need to rent tanks/weights.
2-Jules Undersea Lodge - set up as a dive park to support the underwater hotel, there are platforms, and various items on the bottom. You can look inside the hotel windows. Viz is also about 15-20ft and when the seas are like this, all of the local shops end up taking students there for their check out dives. Admission is $37.50 and tanks/weights extra to rent as well as hot showers.
In the interim, let me know when/where you are in town and maybe meetup for
or break bread.

You do have the option to head over to Crystal River to see manatees where the conditions are not impacted by weather like in Key Largo. The colder the weather, the more manatess in the warm (70deg) springs.
