Dive conditions today, by location
Pick a dive spot to see today's swell, wind, water temperature and visibility estimate, then open it in the app for the tide and current. In the app, the reefs and wrecks layer (Pro) shows charted wrecks, reefs and obstructions nearby, each with the seabed depth beside it (an estimate where no chart reports one) and, where a chart sounding exists, the least depth over it.
North Carolina
1 spotSouth Carolina
1 spotFlorida
13 spotsDiving 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.
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.
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.
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.
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.
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.
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.
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.
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.
"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.
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.
Inshore snook and tarpon fishing, plus the run to the Middle Grounds for serious offshore trips. Easy Gulf of Mexico bottom inside 20 miles.
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.
California
21 spotsKelp 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.
Marine reserve at La Jolla Cove, kelp forest divable all year. Outside the reserve: legendary freediving for white seabass and calico bass.
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.
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.
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.
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.
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.
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.
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.
Deep canyon starts feet from shore. Cold, plankton rich water: lower vis, but rich kelp forest life, lingcod, and cabezon for divers.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Washington
2 spotsCold water diving at its best: giant Pacific octopus, wolf eels, and vivid invertebrate life at sites like Edmonds Underwater Park, Alki, and Redondo. Counterintuitively, vis is often best in winter when the plankton dies back. Currents rule the dive planning here.
A deep glacial fjord off Puget Sound, famous for wolf eels, octopus, and the occasional sixgill shark at Sund Rock. Poor flushing means low oxygen events in late summer can push fish shallow or empty a site, so timing matters.
Hawaii
3 spotsKnown for bluewater spearfishing: mahi, wahoo, and yellowfin tuna off the offshore FAD buoys. North Shore surf breaks in winter are a major draw.
Kona side drops off faster than almost anywhere in the world: 1000ft contour within a mile of shore. Big blue marlin and yellowfin tuna within sight of the harbor.
Molokini Crater diving, Honolua Bay on calm days, plus bluewater trips between the islands. Winter humpback whale migration routes overlap fishing grounds.

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
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.
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.
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.
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.
