I’m from the West Coast, specifically from the Naples-Bonita Springs area.
Visibility is very low, shore diving is not going to be possible nor advisable.
Most West Coast dive shops will have students drive to the east coast, specifically to the FL Keys, to Fort Lauderdale or to a freshwater Lake in the middle of the State to complete open water components.
There are several operators that will take divers offshore in Marco Island, Naples, Fort Myers, Sarasota and Tampa. Those are not daily dive charters, but work occasionally, depending on demand and weather conditions.
Now to the best part. In all honesty, the West Coast of Florida has amazing diving; however, it’s not easy to get to a dive spot because of distance. It will take hours on a good day to trek between 20 and 30 miles to reach a good dive site.
It requires a knowledgeable Captain and reliable transportation and an entire day.
You will find advertisements online offering spear fishing trips. It’s very good in Gulf waters; however, it’s best to venture into the West Coast with a robust level of experience and with a responsible operator.
Local counties have artificial reef programs that attract wildlife. Both Collier and Lee Counties have reef locations available to the public. You can find nice videos on YouTube of folks diving the Middle Grounds, others diving sinkholes off of Naples, Fort Myers and Marco. There are charters in Venice Sarasota area that will take you to sites where you can find fossilized shark tooth- and other old manatee bones can be fetched.
Lee County deployed the USS Mohawk. Feel free to search for YouTube videos of folks diving the USS Mohawk in Lee County.
On a rare instance, visibility opens up and you can actually do some diving pretty close to shore; however, that is an exception... not the norm.
Hope this helps. The West Coast is a great place to live, go to school and work. I’m now living in the East Coast for work reasons, as well as for the diving.
Here is a video that will give you an idea of diving in the West Coast:
