The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.
How we score the water
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.
01
Swell & wave memory
Height, period and direction of the swell, plus the wake of recent storms — an old storm still stirs the water, and the engine remembers.
02
Wind & gusts
Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
03
Tide phase
Timing and range of the tide, calibrated per coast — big spring tides pull the verdict toward caution.
04
Water temperature
Sea-surface temperature — sharply cold water vetoes a green verdict.
05
Currents & outflow
Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
06
Rain runoff & air clarity
Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
07
Coast shape & exposure
How the coast faces the swell — a sheltered cove keeps the water clean; an exposed, head-on point takes a penalty.
Safety gates
Thunderstorm forecast — an instant red, no exceptions.
An official warning (MeteoAlarm / IPMA) — yellow, or red for the higher ranks.
Missing input data — a would-be green is capped to yellow rather than overstated.
Strong disagreement between forecast models — a green day is pulled back to yellow.
Night hours — where night spearfishing is banned by law the window is forced red; where it is legal (Australia outside NSW, New Zealand, South Africa) it is capped at yellow, never green.
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.

What it is
A marine instrument, go / no-go for solo hunting.
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.

Palmetto Bay at Deering Point beach access (Palmetto Bay): shore entry, 3.1 km from Cutler Bay. Florida 68B-20.003(2)(a): no spearfishing within 100 yards (91 m) of the beach. Expect no more than about 1.0 m of water. Inside Biscayne National Park; read its rules first.
SOLO 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.

Surfacing
Cameras, map and reference — to hand as you come up.
Year-round. Min FL 12″ (30 cm), NC/SC 14″, GA 10″. Bag FL 8/person (50/trip vessel limit in Mar–Apr), NC 5, SC 10/person and 30/boat, GA 15. FL expressly allows spearing.
mangrove/mutton snapper
Lutjanus griseus · 5–35 m · legal
Year-round in FL state waters on both coasts. Min 10″ (25 cm), 5/person — but the real constraint is FL's 10-snapper daily aggregate. NC/SC handle it inside the snapper-grouper complex, not as a standalone line.
mutton snapper
Lutjanus analis · 5–40 m · legal
A core Keys / SE-Florida target. Year-round in FL state waters on both coasts and in SC. Min 18″ (46 cm), bag 5/person inside the 10-snapper daily aggregate.
yellowtail snapper
Ocyurus chrysurus · 3–30 m · legal
The Keys' bread-and-butter reef fish. Year-round in FL state waters on both coasts. Min 12″ (30 cm), up to 10/person/day — but inside the 10-snapper aggregate, i.e. that is the whole snapper bag.
black sea bass
Centropristis striata · 5–40 m · legal
A staple on every NC/SC/GA nearshore ledge and artificial reef. Year-round in FL, NC south of Hatteras, SC and GA. Min 13″ (33 cm) FL Atlantic / NC-south / SC, 12″ GA, 10″ FL Gulf. Bag 7/person (GA 15).
gray triggerfish
Balistes capriscus · 10–50 m · ⚠️ closed season/limit
FWC lists 'hook and line, spears, gigs' as legal gear, so it is NOT covered by the FL ornamental-triggerfish spearing ban. FL Atlantic year-round, min 12″ (30 cm), 10/day; FL Gulf open Mar 1–May 31 and Aug 1–Dec 31, min 15″ (38 cm), 1/day.
lionfish
Pterois volitans / P. miles · 1–60 m · invasive — target
Invasive: no season, size or bag limit. No licence needed with a pole spear, Hawaiian sling, hand-held net or a lionfish-specific device. The SPEAR bans still apply: 100 yd from swimming beaches/piers/fishing bridges, 100 ft from a jetty's above-water part, Monroe County from Long Key north to the Miami-Dade line, and any DEP park water — hand-held nets only there.
great barracuda
Sphyraena barracuda · 1–30 m · legal
Year-round. The trap is county-scoped: Collier, Monroe, Miami-Dade, Broward, Palm Beach and Martin run a 15–36″ (38–91 cm) slot, 2/person and 6/vessel plus one fish over 36″. Rest of the state: no size limit, 2 fish or 100 lb, whichever is more.

Law
✓Florida: saltwater licence $17 res / $47 non-res; reef fish need the free State Reef Fish Angler (SRFS) designation. NC: CRFL; SC/GA: saltwater licence.
✓Distances (FL): 100 yd from beaches/piers/bridges, 100 ft from the above-water part of a jetty. banned in FL and SC; rebreathers are illegal for spearfishing in FL.
✓SC: gamefish (red drum/seatrout/cobia/tarpon/striped bass) hook-and-line only (§50-5-1700). GA: speargun doubtful in state water — real hunting on federal reefs.
⛔ 🚫 FLORIDA's full no-spear list (FWC, FAC 68B-20.005): snook, bonefish, tarpon, goliath and Nassau grouper, red drum, spotted seatrout, weakfish, pompano, African pompano, permit, tripletail, spiny lobster, blue crab and stone crab, all billfish, sharks, manta ray and spotted eagle ray, sturgeon — plus any species whose harvest is prohibited by law.
⛔ 🚫 Florida also bans spearing in fresh water, within 100 yards (91 m) of a public swimming beach, a commercial or public fishing pier or any part of a bridge from which public fishing is allowed, and within 100 ft (30 m) of the above-water part of a jetty; ornamental reef fish may not be speared. Federal Gulf waters follow the federal list instead.
⛔ 🚫 Spiny lobster/stone crab — hand-take only (no puncturing). banned in FL and SC. Monroe County (Long Key north to the Miami-Dade line — incl. Key Largo): spearfishing banned; the lionfish licence exemption does NOT override it — hand-held nets only there.
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.
Safety protocol
Sets: watch the wave trains ≥15 min before entering; Hmax ≈ 2×Hs, the wash can run 50 m past the foam line. A lull >10 min with period >12 s = a big set «overdue», do NOT enter; enter right after a full set passes and re-check at minute 30.
Exit FIRST: find your exit AND a backup before entering. On a rocky/boulder shore a 0.5 m rise in swell can make the exit impossible — getting pinned/unable to climb out is the main killer.
Headland rip: prominent points often have a permanent topographic rip regardless of the model — locate it, enter/exit on the windward side, never swim against it.
Cold: wetsuit per the SST chip; the first shiver = a metabolic surge and a drop in breath-hold → get out at the first steady shiver. Cap the session at 45–60 min below 15 °C.
Solo discipline: buoy up; tell someone the spot and exit time; conservative breath-hold (never push it in cold/murky/surfy water); visibility <3 m — don't enter.
Afternoon wind: on many coasts the wind builds from midday — plan to be out of the water by midday; the chop builds — get out.
UV 11:00–15:00 (UVI ≥6): sunscreen and cover up on the surface interval.
Solo is a fundamental risk (hypoxic blackout with no buddy). Any doubt = No-go.
FAQ — spearfishing in Cutler Bay
Where can I spearfish in Cutler Bay?
Cutler Bay has rock entry points such as Palmetto Bay at Deering Point beach access (Palmetto Bay) and Deering Estate beach access (Palmetto Bay). Cutler Bay is a town on the Florida coast of United States; its shoreline faces east, at 80°. Below you'll find each spot (access, shelter and hazards) and today's forecast.
When is the best season in Cutler Bay?
Year-round; the best US regime — snappers/groupers/hogfish, lionfish encouraged.
How cold is the water in Cutler Bay?
Warm year-round, 22–29 °C; the Keys and reefs are gin-clear.
Is Cutler Bay good for a beginner?
Beginner-friendly on the reefs/Keys; mind the Upper Keys ban and the 100-yard rule.
Do I need a licence in Cutler Bay?
Yes — in Cutler Bay almost certainly, but the licence is the STATE's, not a federal one: nearly every coastal state requires its own saltwater fishing licence, and several add a free registration or an extra endorsement on top (Florida's free State Reef Fish Survey for reef fish, Texas's saltwater endorsement, California's Ocean Enhancement Validation). Hawaii asks nothing of residents and charges visitors the NRMFL. What may be speared, and with what gear, is state law too — the price and the details depend on the state, so read the «Law» block below.
Deep ledge, 25–45 m — the classic FL Panhandle and Carolinas spear target. FL Gulf state waters year-round, min 16″ (41 cm); FL Atlantic May 1–Dec 31, min 20″ (51 cm). SC federal waters: 1 scamp or yellowmouth (not both) per person/day.
greater amberjack📋 season by state
The signature wreck and rig fish of the whole façade. FL Gulf (state and federal) OPEN SEP 1–OCT 13 2026 only, min 34″ (86 cm); FL Atlantic closed in April only, min 28″ (71 cm), same in SC and GA. Bag 1/person everywhere.
