Boating in South Florida

South Florida packs a big-city waterfront, a national park and quick access to the Atlantic into one stretch of coast. From Palm Beach County through Broward to Miami-Dade, you can run the Intracoastal past high-rises, anchor off a sandbar or head through an inlet toward deep blue water within minutes. This page covers the main areas, the rules that catch visiting boaters and how to plan a safe day on the water.

South Florida, area by area

Palm Beach County and Lake Worth Lagoon

Lake Worth Lagoon runs behind Palm Beach and connects to the ocean through the Lake Worth Inlet, also called the Palm Beach Inlet, which serves the Port of Palm Beach. Expect commercial traffic near the port and strong tidal currents in the inlet. Farther south, Boca Raton has its own inlet into the Atlantic. The Intracoastal through this county is mostly a narrow, residential waterway with long stretches of slow-speed and no-wake zones.

Broward County and Fort Lauderdale

Broward's waterfront is a dense network of canals, the New River through downtown Fort Lauderdale and the Intracoastal. Port Everglades is both a cruise and cargo port, and its entrance channel is a major inlet for recreational boats as well. Hillsboro Inlet sits at the northern end of the county. With so many private docks and canals, much of the inside water is slow speed or idle, and drawbridges set the pace of any trip along the Intracoastal. See our Intracoastal Waterway guide for how bridges and channel markers work.

North Miami-Dade and Miami Beach

Haulover Inlet connects the Atlantic with northern Biscayne Bay, and the sandbar near it is one of the busiest gathering spots in the region on weekends. South of it, the bay is lined with Miami Beach islands, causeways and residential canals. Government Cut, the main ship channel past PortMiami, carries cruise ships and cargo vessels, so recreational boaters must keep clear of them in the channel.

Biscayne Bay and Biscayne National Park

South of Key Biscayne, the bay opens into a wide, shallow body of water bordered by islands such as Elliott Key and Boca Chita Key. The NPS describes Biscayne National Park as more than 250 square miles of water, and boating is how most people visit. The park reaches from the mainland mangroves across the bay and out to the reefs on the Atlantic side. Stiltsville, a group of houses built on pilings near the northern edge of the park, is a well-known landmark close to Biscayne Channel.

What makes boating here different

Traffic. South Florida has some of the busiest recreational waters in the state. Weekends and holidays bring crowded ramps, sandbars and inlets, plus wakes from large yachts. Keep a steady lookout, slow down early and know the navigation rules for crossing and overtaking.

Inlets. The inlets here are short and can be very rough when an outgoing tide meets an onshore wind or swell. Waves stand up at the mouth and the current can push a small boat sideways. Watch the inlet from a safe spot before you commit, and run it with the tide when conditions are marginal.

Ships in narrow channels. Under the federal navigation rules, a vessel under 20 meters may not impede a vessel that can only navigate safely within a narrow channel. Near PortMiami, Port Everglades and the Port of Palm Beach, that means getting out of the channel early when a ship approaches. Security zones around ports and some vessels are enforced by the Coast Guard.

Shallow bay water. Biscayne Bay looks deep from a distance but is shallow across large areas outside marked channels. The NPS warns that running aground damages seagrass and coral and the boat itself. If you touch bottom, stop, trim up and push or pole off, or wait for the tide. Do not power off.

Bridges. Bascule bridges on the Intracoastal open on schedules or on request, and the waits add up on long runs. Check the current schedules and any closures in the Coast Guard Local Notice to Mariners (opens in a new tab).

Protected areas and local rules

Biscayne National Park

The park's boating page lists the key points for visitors. Personal watercraft, including jet skis and WaveRunners, are prohibited in the park. Observe the slow-speed zones that protect manatees: idle speed means the minimum speed needed to steer with no wake, and slow speed means off plane, fully settled in the water, with no or minimum wake.

The park's mooring buoys are white plastic spheres about 18 inches across, placed next to some popular reefs. Use is limited to four hours per boat, the buoys are for vessels up to 45 feet unless the park authorizes otherwise, and you may not anchor within 300 feet of a mooring buoy. If no buoy is free, anchor in sand downwind of the reef so the line cannot drag across coral. Read diving and snorkeling in Florida before you get in the water.

Anchoring limitation areas

Florida law designates several dense urban waterways in South Florida as anchoring limitation areas under s. 327.4108, F.S. (opens in a new tab). In these areas you may not anchor from one-half hour after sunset to one-half hour before sunrise, with limited exceptions. They include:

• Part of the Middle River in Broward County, between Northeast 21st Court and the Intracoastal
• Sunset Lake in Miami-Dade County
• Sections of Biscayne Bay between named Miami Beach islands, including the waters around Palm, Star, Hibiscus, Rivo Alto, Di Lido, San Marino, San Marco and Biscayne Islands and the Sunset Islands

Counties other than Monroe may also create their own small anchoring limitation areas, marked with signs and buoys, where you may not anchor for more than 45 consecutive days in a six-month period. For anchoring technique and local etiquette, see anchoring and docking in Florida.

Manatee and speed zones

Manatee protection zones and local speed zones cover much of the Intracoastal and many canals in all three counties. Signs show the speed and any seasonal dates. Our environmental rules page explains how these zones work.

Access: ramps, marinas and inlets

Miami-Dade County operates the marinas and ramps closest to Biscayne National Park. The NPS names four: Homestead Bayfront and Black Point, which feed directly into the park, plus Matheson Hammock to the north and Crandon on Key Biscayne, close to Biscayne Channel and Stiltsville. The NPS notes that a marina may close temporarily during heavy traffic until parking opens up, so arrive early on weekends.

Elsewhere, boat access is spread across county and city ramps and many private marinas. Trailer parking is usually the limiting factor. Use our boat ramps and marinas guides to find options, and call ahead for transient slips, fuel and pump-out.

The main ocean inlets, from north to south, are Lake Worth (Palm Beach) Inlet, Boca Raton Inlet, Hillsboro Inlet, Port Everglades, Haulover Inlet and Government Cut. Each behaves differently with wind and tide, so ask locally and watch before you run one for the first time.

Weather and seasons

Winter brings the most pleasant temperatures but also cold fronts with strong north and northeast winds. Those winds blow against the Gulf Stream, which runs close to shore along this coast, and can build steep, dangerous seas offshore and in the inlets. Summer is usually calmer in the morning, with afternoon thunderstorms, lightning and sudden squalls. The Atlantic hurricane season runs from June through November.

Check the marine forecast for both the bay and the coastal Atlantic zones, and see Florida marine weather for how to read it. If you plan to cross to the islands, read Boating to the Bahamas first. Heading south instead? See our Florida Keys guide.

Frequently asked questions

Can I ride a personal watercraft in Biscayne National Park?

No. The National Park Service prohibits personal watercraft, including jet skis and WaveRunners, in Biscayne National Park. You can still ride them in other South Florida waters where local rules allow.

Where can't I anchor overnight in Miami Beach and Fort Lauderdale?

Florida law makes several urban areas anchoring limitation areas, where you may not anchor from one-half hour after sunset to one-half hour before sunrise. They include Sunset Lake and waters between several Miami Beach islands in Biscayne Bay, and part of the Middle River in Broward County.

How long can I stay on a Biscayne National Park mooring buoy?

The park limits each boat to four hours on a mooring buoy, and the buoys are for vessels up to 45 feet unless the park authorizes otherwise. Do not anchor within 300 feet of a mooring buoy.

Which nautical chart covers Biscayne National Park?

The National Park Service lists NOAA chart 11451 for park waters. Use it with tide predictions, because much of the park is shallow.
