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.

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.

Reference
What's in season,
what the law says.
In season now
- red snapperRed snapper: state-set season (typically May–Oct), 2–4/day, 15–16″.
- sheepshead
- flounder
- cobia (ling)Texas: spear NONGAME only (sheepshead/flounder); gamefish (red drum/seatrout/cobia) pole-and-line only.
Law
- ✓Saltwater licence (+endorsement) per state: FL $17/$47, AL res $30, MS ~$13/$30, LA res $32, TX licence + saltwater endorsement.
- ✓Texas: spear only (sheepshead/flounder); gamefish (red drum/seatrout/cobia) pole-and-line only.
- ✓Red snapper: state-set season. Federal reef waters: spear + allowed outside the stressed area, descending device required.
- ⛔ 🚫 Goliath/Nassau grouper, Gulf sturgeon, sawfish, sea turtles, mammals and many sharks — take prohibited.
- ⛔ ⚠️ Texas & Alabama: gamefish (red drum/seatrout) pole-and-line only, NOT by spear. : banned in FL/TX, allowed in federal waters outside the stressed area.
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.
Spearfishing in Biloxi: spots, seasons and rules
Spearfishing Biloxi is better offshore of the barrier islands than inside the brown Sound. FH-9 is the nearest public reef, but it sits in turbid Sound water. FH-5 sits south of the barrier islands where water clears, and FH-3 is the deepest listed nearshore FH mark, with the best snapper potential. Mississippi allows spear and gig take for finfish with a saltwater license, but that permission does not override red snapper seasons or protected species. Around Ship, Horn and other National Seashore islands, keep the 1 mile no-spear buffer.
TL;DR
- Biloxi is a barrier-island visibility puzzle: the Sound is often turbid, while FH reefs south of Ship and Horn islands clear up.
- FH-9 is the nearest public reef, but FH-5 and FH-3 are the better boat runs when you need cleaner water.
- Mississippi allows spear and gig take for finfish with a saltwater license; red snapper remains season and area controlled.
- Keep 1 mile off Gulf Islands National Seashore islands where spearing is banned.
Where are the useful Biloxi spearfishing reefs?
The FH reefs are boat plans. The farther marks cost more weather judgment, but they also put you closer to the cleaner water beyond the barrier-island filter.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| FH-9 | Nearest public reef to Biloxi | Nearshore reef; exact depth not stated | Intermediate in low visibility | Boat from Biloxi | The convenience option, but it sits in turbid Sound water. Use it for short structure checks, not a clear-water expectation. |
| FH-5 | Public reef south of the barrier islands | Nearshore Gulf reef; exact depth not stated | Intermediate boat dive | Boat run past the inside Sound | A cleaner-water step up from FH-9. It is the better choice when the Sound looks dirty but offshore weather is still settled. |
| FH-3 | Deepest listed nearshore FH reef | Deepest of the listed FH options; exact depth not stated | Intermediate to advanced boat dive | Boat, best with a conservative weather window | The clearest listed FH option, with snapper potential. Seasons and distance from protected islands still need checking. |
When does Biloxi water visibility improve?
Biloxi visibility improves after you get past the inside Mississippi Sound. The barrier islands block some sea, but they also separate dirty inshore water from cleaner Gulf water. A calm south-facing forecast and a good look at the City of Biloxi beach stream help, while PNLM6 gives broader Gulf wind and sea context.
What can you legally spear from Biloxi?
The local Mississippi pack says spear and gig are legal for finfish with a saltwater license. Sheepshead and flounder are practical structure targets, and red snapper is possible only when the state or federal season and area allow it. Do not take Goliath or Nassau grouper, Gulf sturgeon, sawfish, sea turtles, marine mammals or prohibited sharks.
How do National Seashore closures affect Biloxi?
The local Biloxi blurb says to keep 1 mile off the national-seashore islands where spearing is banned. That rule matters because the better FH water is near the barrier-island line. Plot the buffer before the trip, and if the boat position is uncertain, stop hunting until you are clearly outside it.
FAQ
Is Biloxi better than Bay St. Louis for visibility?
Usually yes, if you run to FH-5 or FH-3. Inside the Sound, both areas can be turbid.
Can you shore spearfish Biloxi?
The useful spots are public reefs reached by boat. Shore water is usually too turbid and crowded for a sensible spearfishing plan.
Do you need a Mississippi saltwater license?
Yes. Mississippi law requires a saltwater license for recreational saltwater fishing.
Can Biloxi divers spear red snapper?
Only during the relevant open season and in the right waters. Red snapper is season-controlled.
What is the key Biloxi closure?
The 1 mile no-spear ring around Gulf Islands National Seashore islands is the boundary to plot before hunting near Ship or Horn island waters.
