Key Largo
Florida Keys

Diving capital of the US. Crystal clear tropical water, shallow patch reefs, and deep wrecks including the Spiegel Grove and Duane. Consistently 30 to 80 ft vis in summer, more volatile in winter.

Typical summer vis · 30 to 80 ft
Islamorada
Florida Keys

Sportfishing capital of the world. Deep water close to shore, the edge of the Gulf Stream within a short run. Sailfish winter push, mahi summer runs.

Typical summer vis · 30 to 70 ft
Key West
Florida Keys

Southernmost reef structure in the continental US. Marquesas and Dry Tortugas trips for permit, tarpon, and offshore pelagics. Shallower patch reefs inshore for snapper and grouper.

Typical summer vis · 30 to 80 ft
Jupiter
Southeast Florida

Deep ledge runs just offshore, plus the inlet drift for big snook and tarpon. Strong Gulf Stream influence: pelagics push close in when conditions align.

Typical summer vis · 40 to 90 ft
Pompano Beach
Southeast Florida

Shipwreck alley: dozens of intentionally sunk wrecks within 20 minutes of the inlet, plus the world's largest artificial reef project. Year round diving, reliable sailfish in winter.

Typical summer vis · 40 to 80 ft
West Palm Beach
Palm Beach

Drift diving country, where the Gulf Stream runs close enough to sweep divers over reef and wreck off Palm Beach. Blue Heron Bridge at nearby Phil Foster Park is a world famous shore dive for macro life and night diving.

Typical summer vis · 40 to 80 ft
Fort Lauderdale
Southeast Florida

Three parallel reef lines and a graveyard of artificial wrecks within a short run of the inlet. Easy beach entries at Lauderdale-by-the-Sea put reef in reach without a boat. Warm, clear Gulf Stream water most of the year.

Typical summer vis · 30 to 70 ft
Miami
Southeast Florida

Haulover, Government Cut, and the edge of the Gulf Stream just minutes offshore. Sailfish, kingfish, and mahi runs all year. Bonefish flats in Biscayne Bay on the back side.

Typical summer vis · 30 to 70 ft
Tampa Bay
West Florida

Massive estuary with tarpon runs from May to July, redfish and snook all year in the grass flats, and offshore depth for grouper within 30 miles.

Typical summer vis · 5 to 25 ft
Destin
Florida Panhandle

"World's luckiest fishing village." Deep water closer to shore than most Gulf ports. Red snapper mecca in season, cobia push in spring, offshore tuna trips all year.

Typical summer vis · 20 to 60 ft
Panama City Beach
Florida Panhandle

Called the wreck diving capital of the South: dozens of sunk ships and artificial reefs in clear Gulf water, plus jetty and inshore diving at St. Andrews. Cleaner, calmer summer water than the open Atlantic reefs to the south.

Typical summer vis · 30 to 70 ft
Naples
Southwest Florida

Inshore snook and tarpon fishing, plus the run to the Middle Grounds for serious offshore trips. Easy Gulf of Mexico bottom inside 20 miles.

Typical summer vis · 10 to 35 ft
Blue Heron Bridge
Palm Beach

One of the most famous shore dives in the US: shallow water packed with macro life at Phil Foster Park, best in the window around slack high tide when clean ocean water pushes in through the inlet. Seahorses, frogfish, octopus, and rays over a 6 to 20 ft sand and rubble bottom.

Typical summer vis · 10 to 30 ft

California

21 spots
San Diego
Southern California

Kelp forests for white seabass and halibut, plus offshore runs to the Coronado Islands and the Tanner Bank. Cool Pacific water all year; vis improves with offshore winds.

Typical summer vis · 10 to 40 ft
La Jolla
Southern California

Marine reserve at La Jolla Cove, kelp forest divable all year. Outside the reserve: legendary freediving for white seabass and calico bass.

Typical summer vis · 10 to 35 ft
Catalina Island
Southern California

One of the most popular spearfishing and diving islands on the US West Coast. Kelp forests on the front side, bluewater pelagic shots on the back side. Short ferry from LA/OC.

Typical summer vis · 20 to 50 ft
Laguna Beach
Orange County

Orange County's shore diving heart: a string of coves (Divers Cove, Shaw's Cove, Woods Cove) inside marine protected areas, with kelp, reef, and resident sea lions. Much of the coast is no take reserve, so it's a diving and freediving destination more than a spearfishing one.

Typical summer vis · 10 to 30 ft
Palos Verdes
Los Angeles

The rocky peninsula on LA's south edge: kelp lined points and cobble reefs that draw freedivers and spearos for white seabass and calico bass. Lunada Bay and Christmas Tree Cove are classic entries; vis swings hard with swell and runoff.

Typical summer vis · 10 to 30 ft
Dana Point
Orange County

A working harbor and headland at the south end of Orange County, with kelp reef diving off the point and easy boat access to offshore structure. Cooler, clearer water than the beaches to the north, and a launch for Catalina and San Clemente crossings.

Typical summer vis · 15 to 40 ft
Redondo Beach
Los Angeles

LA's most accessible shore diving: Veterans Park drops straight into the Redondo submarine canyon, where cold deep water and resident sea life sit yards off the sand. A reliable dive all year when swell shuts down the open coast.

Typical summer vis · 10 to 30 ft
Santa Barbara
Santa Barbara Coast

Gateway to the Channel Islands and one of the most studied kelp coasts in the world. Warm temperate water, dense kelp forests, and the launch point for crossings to Santa Cruz and Anacapa Islands. Halibut on the sand, white seabass in the kelp.

Typical summer vis · 15 to 40 ft
Channel Islands
Channel Islands

The clearest water in Southern California. Anacapa and Santa Cruz Islands sit far enough offshore to escape mainland runoff, with towering kelp, big yellowtail, and white seabass. A boat trip from Ventura or Santa Barbara, when the weather allows.

Typical summer vis · 30 to 70 ft
Monterey Bay
Central California

Deep canyon starts feet from shore. Cold, plankton rich water: lower vis, but rich kelp forest life, lingcod, and cabezon for divers.

Typical summer vis · 10 to 30 ft
Carmel
Central California

Point Lobos and Carmel Bay hold some of the best shore diving on the West Coast: granite walls, deep kelp, and clearer water than neighboring Monterey Bay. Point Lobos reserve requires a reservation; Monastery Beach's steep shorebreak is for experienced divers only.

Typical summer vis · 20 to 50 ft
Big Sur
Central California

Remote, dramatic, and shut by weather much of the year. When the swell drops, spots like Jade Cove offer clear, cold, kelp lined diving with granite structure and almost no crowd. A committing coast: no easy exits, big surf, and long drives between entries.

Typical summer vis · 15 to 40 ft
Santa Cruz
Central California

The north end of Monterey Bay: kelp reefs off Natural Bridges and the west side, cold plankton rich water, and the famous surf break at Steamer Lane. Lower vis than Carmel but productive hunting for lingcod and rockfish.

Typical summer vis · 10 to 25 ft
Mendocino Coast
Northern California

Rugged, cold Northern California. Long famous for red abalone freediving (that fishery is closed indefinitely), it's now a rockfish and lingcod coast for hardy spearos. Big swell, thick kelp, and short weather windows define the diving here.

Typical summer vis · 10 to 25 ft
Half Moon Bay
San Francisco Peninsula

The coast just south of San Francisco: Pillar Point harbor, the big wave reef at Mavericks, and productive rockfish and lingcod grounds. Cold, often green, big swell water. A fishing and spearfishing coast where timing the swell window is everything.

Typical summer vis · 5 to 20 ft
Bodega Bay
Sonoma Coast

Sonoma County's fishing harbor and the gateway to the rugged North Coast. Salmon and rockfish offshore, Dungeness crab in season, and cold, nutrient rich water that runs green more often than blue. Big swell and strong wind define the diving windows.

Typical summer vis · 5 to 20 ft
Salt Point
Sonoma Coast

A dedicated dive and freedive park on the Sonoma coast, with sandstone reefs, kelp, and one of Northern California's few protected coves for entry. Historically an abalone diving mecca (that fishery is closed indefinitely), now rockfish, lingcod, and cold water that's clear on a good day.

Typical summer vis · 10 to 25 ft
La Jolla Shores
Southern California

A gentle sand beach entry that slopes into the head of La Jolla Canyon. Summer brings leopard sharks into knee deep water; the canyon walls hold octopus and nudibranchs. Surge and plankton can swing the vis fast between days.

Typical summer vis · 10 to 30 ft
Casino Point
Southern California

Catalina's roped off dive park beside the Avalon Casino: giant kelp, tame kelp bass and garibaldi, and a stair step entry off the rocks. Among the most reliable visibility in Southern California.

Typical summer vis · 30 to 60 ft
Monastery Beach
Central California

A steep sand entry straight onto the lip of Carmel Canyon: deep kelp and drop off diving for experienced divers, with a shore break that demands calm day timing and real respect.

Typical summer vis · 20 to 40 ft
Monterey Breakwater
Central California

The classic Central California training and checkout dive at San Carlos Beach: an easy sand entry along the breakwater wall, sea lions hauled out on the rocks, and metridium fields a short kick out.

Typical summer vis · 10 to 30 ft

Where the numbers come from

Each location page carries a dated snapshot of wind, waves, swell and water temperature from the same feed the app uses, and refreshes it in your browser. Wind, waves, swell, water temperature and current come from global weather and marine forecast models. Wave height is blended with the nearest NOAA or CDIP buoy when one is within about 60 km, tides come from NOAA predictions within about 50 km of a US station and a global tide model elsewhere, and warnings come from the National Weather Service. The visibility estimate starts from each spot's typical clarity for the month, built from diver surveys and in water measurements with satellite ocean color filling the gaps, and adjusts for waves and tide. In the app, every factor in the 0 to 10 rating is tappable, so you can see why the day scored the way it did.

Common questions

Does Submarius show water visibility for diving?

It shows a visibility estimate in Scuba, Freediving and Spearfishing modes. It's a model estimate, not a measurement, shown with a confidence figure, so treat it as a guide.

Does Submarius show current or water temperature for diving?

Yes. Scuba and Freediving modes show sea surface temperature with the air temperature underneath, and a current tile with drift in knots, its direction and the next slack. The current comes from a regional ocean model, so it's the drift offshore, not the current at your entry. There's no bottom temperature or thermocline reading.

Are the safety features available to free users?

Yes, every one, permanently. Safety Watch lets you file a plan with a "back by" time and pick who watches. If you don't check in, the server alerts them by push or email, even if your phone is dead or out of signal. SOS goes to your contacts after a 5 second cancel window. Safety Watch needs a free account, and it alerts the people you pick, not the coast guard.

What's free and what's Pro?

Today's 0 to 10 rating and every tile for today are free, along with the next 12 hours, the best 3 hour window, National Weather Service warnings, trip recording and every safety tool. Pro is $12.99 a month or $99 a year, each with a 7 day free trial, or $149 once with no trial. Those are US prices, and other countries differ. Pro adds forecast days 2 to 8, the reefs and wrecks layer and the other Pro map layers, such as NOAA charts, bathymetry, reef habitat (tropical waters), sea surface temperature, wind and forecast radar (continental US), plus cam playback and offline map areas.
