Rules, timetables and tax rates as read on the issuing body's own pages and data on 27 October 2026. Artificial reef counts are from the Florida Fish and Wildlife Conservation Commission's statewide layer; water is NOAA satellite data for 2021 to 2025, explained below.

Fort Lauderdale's reef starts at the sand; Miami's buoyed wrecks are a boat ride south

The first difference between Fort Lauderdale vs Miami is how you get to the reef. Broward County has 24 miles of Atlantic coast, and it divides the reef that follows it into an Inner Reef in 20 to 30 feet of water, a Middle Reef in 40 to 60 feet and an Outer Reef in 50 to 100 feet. At one town the reef is close enough to swim to.

The usual entry is Lauderdale-by-the-Sea, the small town just north of Fort Lauderdale. Its government calls itself “Florida’s Beach Diving Capital”, keeps a tank rack at the Datura Avenue beach portal and says three coral reefs lie within 100 yards of the beach. Two marked snorkel trails run in 10 feet of water. The SS Copenhagen, a state underwater preserve, lies less than a mile out and is reached by boat.

Miami's buoyed wreck trail is farther away. Biscayne National Park's Maritime Heritage Trail has six mapped wrecks with mooring buoys, and the Park Service states that “access to the sites on the trail is by boat only”. The buoys over the Mandalay sit about 38 km from MiamiCentral station in a straight line, about as far as Brightline's Fort Lauderdale station. Plan on a charter, not a walk.

Closer to town, the shallowest new entries are off the beaches. In October 2025 Miami-Dade placed 22 concrete cars, the ReefLine project, at its South Beach artificial reef site in 22 feet of water. The shore diving list covers other coasts where the reef begins at the sand, as it does at Lauderdale-by-the-Sea.

Broward's 128 artificial reefs sit deeper than Miami-Dade's 277

Both counties have sunk ships for decades, and the state keeps one list of all of it. The Florida Fish and Wildlife Conservation Commission's artificial reef layer, last edited in May 2026, files 128 deployments in Broward and 277 in Miami-Dade. That count includes boulders, concrete modules and memorial reef balls as well as ships.

The ships are where the counties differ. Counted by the depth the state records:

Nearly half of Broward's wrecks, 35 of 74, lie between 61 and 100 feet. Miami-Dade has more at both ends: shallow hulls and barges off Key Biscayne and Miami Beach, and a long tail below 130 feet. A few of the shallow Miami-Dade entries lie inside Biscayne Bay rather than on the ocean side. Broward's own page counts differently and says the county has created “over 150 artificial reefs” since 1982.

For a new diver this matters more than the totals. A month of wreck diving from Fort Lauderdale means many dives in the 60 to 100 foot band, which is where a deeper certification and the nitrox question come in. In Miami a first-week diver has more shallow steel to choose from. The wreck diving guide compares other coasts built the same way.

Biscayne National Park off Miami: no entrance fee, boat only, buoys at 8 to 22 feet

Biscayne is Miami's answer to Fort Lauderdale's beach reef, and it costs nothing to enter. The Park Service states that “the park has no entrance fees” and that the park is 95% water. The trail wrecks are shallow. The park's buoy list puts the Mandalay at 8 to 11 feet, the Erl King at 15 to 20, the Alicia at 16 to 20 and the Lugano at 18 to 22. It names the Erl King, Alicia and Lugano as best suited to scuba, and the Mandalay as the snorkeler's wreck.

Two rules come with the buoys. Mooring buoy use is limited to four hours by any one boat. And anchoring anywhere in the Legare Anchorage, the box over HMS Fowey east of Elliott Key, is prohibited except in an emergency. The Fowey Rocks Lighthouse is on the trail too, with its own ring of mooring buoys; the tower itself is closed to the public.

Fishing law inside the park is mostly Florida's. The Park Service writes that fishing regulations “are set by the Florida Fish and Wildlife Conservation Commission”, and that fishing with a spear “shall be in accordance with State law”. The exceptions that matter to divers are about lobster, below. The Miami diving guide covers the trail's history and the park's founding law.

One aquatic preserve covers the Fort Lauderdale and Miami reefs, and stops where Biscayne begins

Since 1 July 2024 the reef off both cities has had a state name and status: the Kristin Jacobs Coral Aquatic Preserve, formerly the Kristin Jacobs Coral Reef Ecosystem Conservation Area. Florida Statutes section 258.39 sets its boundary as “the sovereignty submerged lands and waters of the state offshore of Broward, Martin, Miami-Dade, and Palm Beach Counties from the St. Lucie Inlet to the northern boundary of the Biscayne National Park”.

The Department of Environmental Protection gives it 240,782 acres over 105 miles. So in the Fort Lauderdale vs Miami choice, the state reef rules are the same on both sides of the county line. South of that boundary the reef is inside Biscayne National Park, where the Park Service applies Florida's fishing rules plus the park-specific ones.

The rule that reaches a diver's boat is the Florida Coral Reef Protection Act, section 403.93345, which covers the reefs off Broward and Miami-Dade among five counties. Anchoring on a coral reef costs $225 per occurrence, with another $225 inside an aquatic preserve; a lawfully registered recreational boat gets a warning letter at least once instead. A grounding must be reported within 24 hours and the vessel removed within 72. The department says nearly 300 mooring buoys sit inside the preserve. Use one instead of the anchor.

Lobster mini-season: 12 a day off Fort Lauderdale, 6 in Biscayne

Florida's two-day sport season runs on “the last Wednesday and successive Thursday of July”, which next falls on 28 and 29 July 2027. Rule 68B-24.004 splits the limit by place. Outside Monroe County and Biscayne National Park, a diver may take 12 spiny lobster a day. In Biscayne National Park the limit is 6. Off Fort Lauderdale you get the higher number; off Miami it depends on which side of the park line the boat stops.

Some of the park is closed outright. Lobster harvest is banned in its five Coral Reef Protection Areas, Fowey Rocks Lighthouse among them, and in the Biscayne Bay/Card Sound Lobster Sanctuary. The night-diving ban of the mini-season applies in Monroe County only, so it does not reach either city.

The regular season runs from 6 August to 31 March, with 6 lobster per person per day everywhere. The carapace must measure more than 3 inches, measured in the water with a gauge you carry. Egg-bearing females stay. Any device that could puncture the shell is banned, so no spears. A visitor needs a nonresident saltwater fishing license, set in statute at $15.50 for three days, $28.50 for seven or $45.50 for a year, plus a $5 spiny lobster permit, unless an exemption applies.

Spearfishing off Fort Lauderdale and Miami: one federal box and a 100-yard rule

Neither county sits inside Florida's statutory spearfishing ban, which section 379.2425 limits to Pennekamp, Collier County and the Upper Keys down to Long Key. What applies on both coasts is rule 68B-20.003. It bans spearfishing within 100 yards of public bathing beaches, commercial or public fishing piers and fishing bridges, within 100 feet of a jetty, and in water run by the state parks division.

That rule bites hardest where Fort Lauderdale is strongest. The town puts Lauderdale-by-the-Sea's three shore reefs within 100 yards of its public beach, inside the distance the rule protects. Shore diving there is for looking.

Miami adds a federal line. Federal rule 50 CFR 622.182 draws the Key Biscayne/Artificial Reef-H special management zone, a box between 25°41.32′ and 25°42.82′ N, and says that there “Use of spearfishing gear is prohibited”. It is one of two such zones in the rule, and none of the section's zones lies off Broward. Plotted against the state's reef coordinates, 37 of Miami-Dade's artificial reef deployments fall inside the box, among them the Rio Miami, the Belzona wrecks and the Neptune Memorial Reef. Before you pack a gun, read our guide to starting spearfishing.

Dive-flag distances are the same in Fort Lauderdale and Miami, and channels cut them to 100 feet

Florida Statutes section 327.331 applies statewide, so this part of Fort Lauderdale vs Miami is a tie. “All divers must prominently display a divers-down warning device in the area in which the diving occurs, other than when diving in an area customarily used for swimming only.” The symbol must be at least 12 by 12 inches from the water and 20 by 24 inches from a boat.

On open water, divers must make reasonable efforts to stay within 300 feet of the flag and boats to keep 300 feet away. On rivers, inlets and navigation channels both figures drop to 100 feet. That matters near the Port Everglades and PortMiami entrances. A boat inside those distances must slow to the speed needed to keep headway and steerage. The flag has to come down once every diver is aboard or ashore.

The swimming-area exception is narrow. A shore diver at Lauderdale-by-the-Sea who heads out to the second reef has left the swimming area, so tow a buoy with a flag.

Fort Lauderdale vs Miami water temperature: the same sea, a few tenths apart

The two coasts share one current and one sea surface. NOAA's satellite record puts them within 0.3 °C of each other in every month:

Monthly means of NOAA's OISST v2.1 sea surface temperature, January 2021 to December 2025, for the quarter-degree cells centered at 26.125° N 80.125° W (the Fort Lauderdale shore from Port Everglades to Lauderdale-by-the-Sea) and 25.625° N 80.125° W (Key Biscayne and Fowey Rocks), read from NOAA PSL's monthly file sst.mon.mean.nc.

From November to January the Fort Lauderdale cell runs 0.2 to 0.3 °C warmer; from March to July the Miami cell is warmer by up to 0.2 °C. Single months ran cooler than the average: the coldest monthly mean in the five years was 24.1 °C off Fort Lauderdale (February 2024 and January 2025) and 23.5 °C off Miami (January 2025). A cell is about 25 km across, so it shows the open sea, not a cold morning on one reef. Pack the same wetsuit for both: a thicker one from December to March, a thin one from June to October.

Storm season does not split either. The National Hurricane Center gives the Atlantic season as 1 June to 30 November, with its peak on 10 September and most activity between mid-August and mid-October.

Brightline and Tri-Rail between Fort Lauderdale and Miami, and from FLL and MIA

You do not have to choose one city for a whole month. Brightline runs between its Fort Lauderdale station and MiamiCentral 18 times each way on a weekday, by its own timetable data for Wednesday 28 October 2026. Southbound takes 38 minutes and northbound 33. The first train leaves Miami at 05:45 and the last southbound leaves Fort Lauderdale at 23:53.

Tri-Rail is the commuter line, and it serves both airports. On a weekday its timetable has 25 trains each way between Fort Lauderdale station and Miami Airport station, 46 to 54 minutes, and 15 each way on a Saturday. The line stops at Fort Lauderdale Airport station, where a Tri-Rail shuttle bus loops to the terminals, 65 times on a weekday. Miami Airport station is the southern end of the main line. MiamiCentral is reached by a separate Tri-Rail link from the Metrorail Transfer station, 13 trips a weekday.

Brightline's South Florida stops are Miami, Aventura, Fort Lauderdale, Boca Raton and West Palm Beach; its one airport stop is Orlando's. From FLL or MIA, Tri-Rail is the train that starts at the airport. Check how your dive boat's marina connects to the station before you book a room by the tracks.

What a month in Fort Lauderdale or Miami costs in tax and licences

A furnished rental of six months or less carries Florida's transient rental taxes. The Department of Revenue's rate sheet, revised in October 2026, lists a local rate of 6% in Broward and 6% in Miami-Dade, except 7% in Miami Beach and 4% in Surfside and Bal Harbour. Both counties add a 1% discretionary sales surtax to the 6% state sales tax. On a one-month rental that is 13% in Fort Lauderdale and in Miami-Dade outside those three towns, and 14% in Miami Beach.

The diving extras cost the same too. Biscayne charges no entrance fee, the reef protection act applies on both sides, and the fishing licence is statewide. Rent is the line to compare yourself, for your own dates.

Fort Lauderdale and Miami dive businesses on our lists

Both lists come from training-body registers, so they show who is affiliated, not who is good.

The Fort Lauderdale list was compiled on 1 September 2026 and the Miami list on 20 September, with one IKO school added on 25 September. Only one of the eight Fort Lauderdale entries is filed in Fort Lauderdale itself: SSI files three in Pompano Beach, two in Dania Beach, one in Sunrise and one in Lauderhill. All four Miami dive centers are filed in Miami. SSI also rates one center on each list for extended range, and Ace Diving in Miami for rebreathers.

The Fort Lauderdale operator list and the Miami operator list link each entry to its register page. Before a deep wreck month, check that your dive insurance covers chamber treatment. Divers Alert Network's guidance is to call 911 first in a life-threatening emergency, then its hotline on +1-919-684-9111.

Fort Lauderdale for walk-in reef and 60-to-100-foot wrecks, Miami for Biscayne

Base in Fort Lauderdale if you want to dive without a boat on some days, if you are certified for the 60 to 100 foot band where nearly half of Broward's wrecks sit, or if lobster season is the point. Lauderdale-by-the-Sea is the address that matters. The Fort Lauderdale diving guide covers the SS Copenhagen and the Lady Luck. Do not plan to spear from the beach.

Base in Miami if you are newly certified or snorkel as much as you dive, because the Biscayne trail and the Key Biscayne barges are shallow. Expect to book boats for nearly everything. For a long stay, Fort Lauderdale vs Miami need not be either/or: Brightline makes a split month easy. Heading on south, Key Largo vs Key West picks up where Biscayne ends.

Note: Fishing and lobster rules change by commission vote, and timetables change with the season. Check the current rule with the Florida Fish and Wildlife Conservation Commission and the timetable with the operator before you dive or travel.
