How to Find Lobster Spots in Florida: Bottom, Water & GPS

Most of the bottom you idle over on a lobster trip is empty. Florida's shallows run for hundreds of miles, but lobster concentrate on the small fraction of it that pairs hard structure with food nearby, and everything in between is just sand. Learning to recognize productive bottom, ideally from the surface before you ever get wet, is what separates a full bag from a long day of swimming. Here's how to read it, and the fastest way to skip straight to proven bottom.

What makes a spot a lobster spot

Every productive spot comes down to two ingredients sitting next to each other: hard structure to shelter in, and open foraging bottom to feed on. Get both together and you have a spot. Get only one and you usually don't.

• The structure is anything with holes and edges to hide under: rock piles, ledges and undercuts, coral heads, patch reefs, and exposed hardbottom (the old reef rock, riddled with pockets). This is where lobster spend the day.
• The food is the seagrass and sand flats right beside it, where they walk out to forage at night.

Two more rules narrow it down fast. First, depth: the large majority of productive spots sit in under 20 feet, which is ideal for free-divers and where most of the good structure lives. Second, edges, not tops: lobster tuck into the overhangs and the seams where structure meets sand, not on top of a clean reef. For the full breakdown of each habitat type, see the lobster habitat guide; for reading it once you're in the water, the how to find lobster guide covers the in-water tells. This guide is about finding the spot in the first place.

What lobster bottom looks like from the surface

Here's the skill most people never develop: you can read productive bottom from the boat, before anyone gets wet. In Florida's clear, shallow water, structure gives itself away by color.

Bare sand looks pale, almost white. Everything that holds lobster, seagrass, hardbottom, rock, coral, and reef, reads as darker patches against it. So as you idle, you're looking for dark blotches and hard tonal changes in a field of light sand, and especially the edges where dark meets light. A dark grass or reef patch dropping off to clean sand is exactly the shelter-plus-food pairing you want.

A few things make that easier to see:

• Wear polarized sunglasses. They cut the surface glare and let you actually see the bottom. This is the single biggest upgrade to reading water.
• Time it for high sun. Midday, roughly 10 to 2, with the light coming down steep, lights up the bottom. Early and late, glare and low angles hide it.
• Keep the sun at your back as you scan, and pick calm, clear days. Chop and murky water erase the color. That's part of why conditions matter so much, covered in the weather guide.

Idle slow, read the color, and mark the dark edges. You're building a list of spots to drop in on without wasting a single dive on empty sand.

Scouting before you leave the dock

The best spot-finding happens at the kitchen table. You can do most of the work before you burn a drop of fuel.

• Satellite imagery. In the shallow, clear water from Miami through the Keys, hardbottom, patch reefs, and grass beds are visible from space. Open Google Earth, pan the shallows, and you'll see the same dark patches you'd read from the boat. Drop pins on the promising ones and you've got a scouting list before you leave.
• Nautical charts. NOAA charts show depth contours, plus rock, reef, and wreck symbols. Use them to find the right depth band and the structure marked on it.
• Artificial reefs. Florida has one of the largest artificial reef programs in the country, with thousands of public reefs at published coordinates. Many hold lobster, and the artificial reef guide covers how to search them by county and depth.
• Your sounder, on the water. A depth finder confirms hard bottom and relief where the satellite left off, and side-scan (if you have it) is even better. Mark what produces and you slowly build a milk run of spots you can work trip after trip.

The catch: scouting eats time and fuel

All of that works, and plenty of locals built their spot lists exactly this way. But be honest about the cost. Prospecting new bottom means a lot of idling, drifting, dropping in on holes that turn out empty, and running between marks, and that adds up to fuel, daylight, and usually several trips before you have a set of spots you can count on.

For a visitor with a weekend, or the two days of mini-season, that learning curve can eat the entire trip. And even seasoned locals burn gas re-finding bottom after a storm pushes sand around and buries the hardbottom that was producing last month. Finding spots the hard way is a real, ongoing tax on your time on the water.

The shortcut: start from proven GPS numbers

The way to skip the tax is to not start from zero. That's the whole idea behind Lobsterly: a set of 3,000+ proven lobster spots from Haulover Inlet to Key West, most in under 20 feet with foraging habitat right beside them, so you're diving productive bottom on day one instead of scouting for it.

• Green Lobster Zones show you where to hunt for structure, and thousands of waypoints mark the specific spots inside them.
• Every no-take zone is marked, so you know what's off-limits before you drop.
• It includes 4,500+ Florida artificial reefs, and it all works offline once you're past cell range.
• It's a one-time purchase, no subscription.

What that really buys you is a smarter run: instead of wandering, you plan an efficient loop between known spots, which saves fuel, saves daylight, and puts you on lobster faster. You don't have to take it on faith, either. You can start free with a sample of spots to see how it works (free Florida lobster spots), and if you want to compare every option, the buying spots guide lays out GPS files, charters, and apps side by side.

Keep your own list in the Lobsterly app

The proven waypoints get you started, but the real payoff comes from making the map your own. Lobsterly is built to work like a logbook, not just a spot list, so every trip turns into intel for the next one.

• Favorite the spots that produce. Star the waypoints that come through for you and they're a tap away next time, so your best bottom rises to the top of the map.
• Add notes to any spot. Jot down the depth, the structure, what produced, the conditions, and the date. Next season you're reading your own notes instead of guessing.
• Save your own spots, privately. Found a ledge that isn't on the map? Drop your own waypoint. Your personal spots live on your device, not on a public feed, so the bottom you worked to find stays yours.
• Share personal spots with friends. When you do want to let a buddy in on one, you can send them your own saved spots. Only your personal spots are shareable, so nothing gets exposed that you didn't choose to share.

Here's the habit that separates the divers who get better every season: log the spots that looked good even when they came up empty. Lobster aren't fixed to one piece of bottom. They shift dens night to night and move across the reef and the shallows with the seasons and the cold fronts, the whole story in the migration guide and the day in the life guide. A ledge that's bare today can be stacked next month, so a promising spot with no bugs is still worth a pin and a note. Over a season those notes become a personal, ranked list no dataset can match, because it's tuned to exactly how and where you dive.

Put it together

A simple workflow that works whether you're scouting your own bottom or starting from a proven list:

1. Do your homework. Pre-scout dark bottom on satellite and charts in the right depth band, or load a proven set of waypoints and plan a fuel-smart run between them.
2. Read the water on the way. Idle slow, sun at your back and polarized glasses on, and pick out the dark edges against the sand.
3. Confirm with the sounder. Check for hard bottom and relief before you commit a dive.
4. Check that it's legal. Make sure the spot is outside every no-take zone.
5. Keep score in the app. Favorite the spots that produce, drop and note the promising bottom you find, and your own list grows every trip.

Finding lobster spots is a skill you can absolutely build yourself. It just takes time and fuel that a proven set of numbers gives back to you. That's the fastest path from the ramp to a full bag.

Frequently asked questions

How do you find lobster spots in Florida?

Look for hard structure with food nearby: rock, ledges, coral heads, patch reefs, or exposed hardbottom sitting next to seagrass or sand, usually in under 20 feet. You can spot that bottom from the surface as dark patches against pale sand (polarized glasses, high sun), pre-scout it with satellite imagery and charts, and confirm it on your sounder. The fastest route is to start from a proven set of GPS waypoints so you skip the trial and error.

What does lobster bottom look like from the surface?

Dark patches and hard color changes against pale sand. Seagrass, hardbottom, rock, coral, and patch reefs all read as darker bottom; bare sand looks light or white. The productive edges are where dark meets light. It's easiest to see around midday with the sun high and behind you, in calm clear water, wearing polarized sunglasses.

Is it worth buying lobster GPS coordinates?

For most people, yes. Scouting productive bottom yourself takes time, fuel, and often several trips, which is a lot if you only have a weekend or the two days of mini-season. A proven set of waypoints gets you on lobster fast and lets you plan a fuel-efficient run. You can start free with a sample of spots and add more as you go.

Conditions and regulations change. Always confirm the latest rules on the FWC spiny lobster page before you dive. Last updated July 2026.
