Hi
@godive1
I would think your best chance to see sharks would be in Jupiter. I have used Jupiter Dive Center for 11 years, there are other good operators that others could recommend. As others have mentioned, your visit will be early in Lemon Shark aggregation. The dive at Lemon Drop is a very good opportunity to dive with many Lemon Sharks. On Fridays, the 1st dive of the 3 tanker is often at Deep Ledge, this is a chance to dive with Bull Sharks. There are very frequently Reef Sharks on the reef dives, Lemon Sharks are there too.
I agree with
@Biotech Diver the reefs of Boynton Beach are my favorite. Sharks sightings are considerably less frequent than in Jupiter. If you have a chance to do the Castor wreck, there is a nice endemic population of Goliath Grouper and a couple of Bull Sharks are often seen cruising the perimeter. I generally use Underwater Explorers, but Kevin has not been running recently due to Covid and school obligations. I frequently go out with Loggerhead and Starfish.
As others have mentioned, the winter sea conditions are highly variable. Boynton Inlet tends to be the most affected, Jupiter is intermediate. When seas are up, I often can get out of West Palm, the most forgiving of the 3 inlets. West Palm has nice reefs and wrecks. Governor's River Walk and the Mitzpah, Ana Cecilia Corridor can both be nice. I generally go out with Narcosis, sometimes Walker's Dive Charters. Again, there are several additional good operators
If you can't get out into the ocean, the Blue Heron Bridge can be a very nice backup dive
Sorry, I can't help you with the diving south of Boynton Beach. Hope you have a good visit, let us all know how it went.
