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.
- 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.
- Wind & gusts
- Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
- Tide phase
- Timing and range of the tide, calibrated per coast — big spring tides pull the verdict toward caution.
- Water temperature
- Sea-surface temperature — sharply cold water vetoes a green verdict.
- Currents & outflow
- Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
- Rain runoff & air clarity
- Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
- 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 — forced red; the window is closed after dark.
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.

Visibility and what drives it — post-storm clearing, river plume, temperature and the thermocline.
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: 1152 spots across 189 stretches of coast — mainland Portugal, Madeira and the Azores.

On the rock
The forecast is the plan.
The call is on the rock.
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.

Nearshore reef 3.4 nm off Bogue Inlet; sheepshead, black sea bass, flounder and triggerfish. ⚠️ State-water AR (<3 nm) may be no-spear — verify with NC DMF before hunting.
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.

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».

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.
- ⛔ 🚫 Do not spear (FL FAC 68B-20.005): snook, red drum, spotted seatrout, tarpon, bonefish, pompano, goliath/Nassau grouper, billfish, sharks, rays + ornamental reef families.
- ⛔ 🚫 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.
