Today — right on the edge — wave, wind and noticeable surge.

The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.
Our own model
Our own forecast engine — not a third-party widget. It weighs these water factors into one go-or-stay verdict for this coast; the 0–10 dial is that verdict, read out as a number.
Safety gates
It all folds into a single 0–10 score and one verdict: go or stay.
A forecast, not a guarantee — the sea has the last word.

spearo.app folds wind, wave, swell period, visibility, tides, water temperature and risk into a single verdict — go to the spot or not. It computes 7 days ahead from open marine models (Open-Meteo, IPMA), with no sign-up and no accounts. Built for solo spearfishing off the rocks, where any mistake costs dearly.
Now live: 3016 spots across 406 stretches of coast — mainland Portugal, Madeira and the Azores.

The models set the window. Whether you go in is read only at the water: count the sets, watch the surge on the entry. If in doubt, you don't get in.
Scouted entries, coloured by today. The colour is the sea state at the spot, not a guarantee: the wash and a slippery entry you judge on site.
Open the seafloor mapTwo Vietnam-era M-60 tanks placed in 1994 with about a thousand tonnes of limestone boulders around them, 13-15 m off Miami Beach. Shallow, distinctive and an easy freedive; hogfish, mangrove snapper and grunts on the boulder field, with the tanks as the marker.
Google MapsWARNING: a 195-ft barge sunk upside down in 1985 off Key Biscayne, 16-18 m, now so overgrown it reads as reef; openings in the bulkhead let divers inside. It lies in the Artificial Reef-H SMZ, where 50 CFR 622.182(a)(2) prohibits spearfishing gear.
Google MapsJose Cuervo Bar: you go in from the shore, some 1.1 km from Miami. Marker position: 25.769° N, 80.128° W. Maximum depth is around 7 m. Spearfishing in Florida is barred by structures such as piers and bridges and at lifeguarded beaches (68B-20.003(2)); check signage locally.
Google MapsWARNING: hull with about 12 m of relief off Government Cut in 21 m, inside the Artificial Reef-H SMZ, where 50 CFR 622.182(a)(2) prohibits spearfishing gear. Dive it without the gun; heavy cruise-ship traffic passes close by.
Google MapsWARNING: the 118-ft steel tug Orion, first vessel of the Miami-Dade artificial-reef programme (1981), upright in 24-27 m on the Belcher's rebar-marked trail. The trail sits in the Key Biscayne SMZ: spearfishing gear prohibited, 50 CFR 622.182(a)(2).
Google MapsWARNING: shallow wreck in 11 m off Key Biscayne, inside the Key Biscayne / Artificial Reef-H Special Management Zone. Federal rule 50 CFR 622.182(a)(2) prohibits spearfishing gear in this box. Information zone: a dive to look, not a place to hunt.
Google MapsWARNING: deeper wreck cluster off Miami in 26 m, within the Key Biscayne SMZ of 50 CFR 622.182(a)(2): spearfishing gear is prohibited across the whole box. A sightseeing dive for experienced divers, not a hunting mark.
Google MapsSOLO is the biggest risk: underwater you can black out from lack of oxygen silently and fatally, with no one around. Solo is never truly «safe». Below are the best weather windows; carry a buoy, tell someone your plan and exit time, and any doubt — don't go.
Cameras, map and reference — to hand as you come up.
Check the cam BEFORE you leave. Foam, brown/green murk, or waves washing the entry rocks = No-go. At night/in fog the cam is useless — treat it as «unknown», NOT «green».
US spearfishing law is state-by-state. License, spearable species, powerhead rules and distances vary; federal sanctuaries (Gray's Reef, the Keys, Flower Garden Banks) ban spearfishing. Always confirm with the state agency and local ordinances.
Miami spearfishing is about choosing legal structure outside the wrong boundaries. The listed wreck notes place Rio Miami, Ophelia Brian Reef and Tacoma north of Biscayne National Park, so they are treated here as wreck sites rather than park water. They can hold mutton or mangrove snapper, hogfish, grouper when open, cobia, sheepshead and flounder. The limiting factors are boat traffic off Government Cut, current, and Florida's long list of species that cannot be taken by spear.
These three wrecks are close to the city but should be planned as boat dives. None is marked no-take in the record, and each note places it north of Biscayne National Park.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Rio Miami | Shallow wreck | Shallow wreck profile off Key Biscayne | Intermediate boat dive | Boat, north of Biscayne National Park | A practical structure check when water is clean. Use a divers-down flag and avoid drifting toward park or channel restrictions. |
| Ophelia Brian Reef | Wreck and artificial reef | About 40 ft of relief in the record | Intermediate | Boat off Government Cut | The relief can attract snapper and hogfish. Government Cut traffic makes surface discipline non-negotiable. |
| Tacoma | Deeper wreck cluster | Deeper than the shallow reef stops | Advanced freediving team | Boat, north of Biscayne National Park | A better fit for experienced freedivers with depth, current and recovery procedures set before the first drop. |

A Florida saltwater license is the starting point, and reef fish require the free State Reef Fish Angler designation. FWC bans powerheads and rebreathers for spearfishing. It also prohibits spearing within 100 yards of public swimming beaches, public fishing piers and qualifying bridges, and within 100 ft of most above-water jetty sections. Miami divers also need strict divers-down flag behavior.
FWC lists many prohibited species that matter in Miami. Do not spear snook, red drum, spotted seatrout, tarpon, bonefish, pompano, goliath grouper, Nassau grouper, sharks, rays, billfish, lobster, stone crab or ornamental reef families. Legal targets can include hogfish, snapper, sheepshead, cobia and flounder, with grouper only when the exact season, size and zone line up.
Miami can be clear and still be a poor spearfishing day if current or boat traffic is wrong. The record points at trouble from the east sector, so watch easterly swell before committing to the wrecks. NOAA Station 41122 gives a nearby sea-state signal, while the Port Miami camera helps judge Government Cut surface traffic and wind texture.
Yes, where state, federal, park and local boundaries allow it.
Yes. Florida reef fish require the free SRFS designation.
No. FWC lists lobster as prohibited for harvest by spearing.
Hogfish, snapper, sheepshead, cobia and flounder are realistic; grouper depends on season.
NOAA NDBC Station 41122 is the local Miami offshore station.
