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.

Reference

What's in season,
what the law says.

In season now
  • sheepshead
    Archosargus probatocephalus · 2–15 m · legal
    Year-round across the façade. AL 12″ (30 cm) and 8/person, MS 14″ (36 cm) and 15, Louisiana neither a size nor a bag limit, TX 15″ (38 cm) and 5/day. Sheepshead is nongame in Texas, so gig, spear and speargun are lawful there.
  • cobia (ling)
    Rachycentron canadum · 3–30 m · ⚠️ closed season/limit
    In TEXAS cobia may NOT be taken by spear at all: it is on the game-fish list and 'game fish may be taken only by pole and line'; gig, spear and speargun are for nongame fish only. AL, MS and LA: year-round in state waters, min 36″ (91 cm), 1/person (MS 2), max 2/vessel.
  • gray (mangrove) snapper
    Lutjanus griseus · 5–35 m · legal
    The most reliable rig and jetty snapper from Alabama to Texas. Year-round in AL, MS and LA: min 12″ (30 cm), 10/person (in LA inside the 10-snapper aggregate). Texas lists no limit — unlisted species carry no bag or length limit there.
  • red grouper
    Epinephelus morio · 15–50 m · ⚠️ closed season/limit
    In Louisiana the rule is depth-keyed: year-round in state waters, but closed Feb 1–Mar 31 seaward of the 20-fathom (120 ft, ~37 m) line. Min 20″ (51 cm) in AL and MS, bag 2/person; in LA inside the 4-grouper aggregate. Texas lists no red grouper limit.

    LDWF reef site in South Timbalier 128, toppled jacket material in 30-34 m about 26 nm south of Fourchon. The classic Louisiana blue-water window is July-September, when the green line pushes inshore; red snapper, amberjack and cobia.

    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.

    A shallow, dependable jetty and marsh-edge target. Year-round in LA and TX; LA slot 16–27″ (41–69 cm), 5/day with max 1 over 27″; TX 14–30″ (36–76 cm), 5/day with max 1 over 52″. MS lists no limit. Nongame in Texas, so lawful to spear there — unlike its red drum cousin.
  • hogfish
    Lachnolaimus maximus · 10–40 m · legal
    This card is LOUISIANA-anchored, not façade-wide: only LA carries an explicit hogfish line — year-round in state waters, min 14″ (36 cm), 5/person/day. No AL or MS hogfish line was found; do not read it as a Gulf-wide allowance. Florida does carry a Gulf line: min 14″ fork length, 5/person/day, year-round — so the sixteen Florida cities on this façade read Florida's rule, not Louisiana's.
  • lionfish
    Pterois volitans / P. miles · 1–60 m · invasive — target
    Invasive: no season, size or bag limit. But the basis here is negative space — lionfish is not a listed species in MS Title 22 Part 3, and Texas states plainly there are no limits except as listed. No AL or LA lionfish line was found. Florida's licence exemption DOES apply to the sixteen Florida cities on this façade: no licence is needed when taking lionfish with a pole spear, Hawaiian sling, hand-held net or a lionfish-specific device.
    • Regulated — check your state
    • red snapper📋 season by state
      Not merely 'typically May–Oct': TEXAS state waters are open ALL YEAR at 4 fish/day, min 15″ (38 cm). LA open from May 1 until further notice, 4/day, 16″. AL and MS set the season annually, 2/person, 16″ (41 cm). Red snapper is nongame in Texas, so spear and speargun are lawful gear. Florida sets its own Gulf state-waters season each year, separate from the federal one: min 16″ (41 cm), 2/person, and the free State Reef Fish Angler designation is required.
    • flounder📋 season by state
      Three DIFFERENT autumn closures inside one façade — there is no single season: AL closed all November, LA Oct 15–Nov 30, TX Nov 1–Dec 14 (bag 0), MS year-round. Min AL 14″ (36 cm), MS 12″ (30 cm), LA none, TX 15″ (38 cm). Flounder is nongame in Texas, so gigging and spearing are the normal legal method there.
    • greater amberjack📋 season by state
      The defining rig and wreck fish of the northern Gulf. Louisiana opens Sep 1 and closes Oct 14. AL/MS follow the federal season; Texas has no state closure. Min 34″ (86 cm), Texas 38″ (97 cm) — and it is nongame there, so fully spearable. Bag 1/person in all four states. Florida runs its own FWC Gulf season: min 34″ fork length, 1/person — check the current year's opening.
    • gray triggerfish📋 season by state
      Texas is the genuine outlier: 20 a day against one a day in AL, MS and LA. Min AL/MS 15″ (38 cm), TX 16″ (41 cm); in LA it sits inside the 20-reef-fish aggregate. Louisiana closed Jan 1–end of February and Jun 1–Jul 31.
    • gag grouper📋 season by state
      The practical spear season on the Louisiana shelf-edge banks is Sep 1–Dec 31 (to 23:59). AL and MS open; Texas has no state closure. Min 24″ (61 cm) in all four states, bag 2/person (in LA inside the 4-grouper aggregate). In Florida the Gulf gag season is set by FWC (in recent years Sep 1–Nov 10), min 24″, 2/person inside the 4-grouper aggregate — check the current year.
    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.

    FAQ — spearfishing in Port Fourchon

    Where can I spearfish in Port Fourchon?

    Port Fourchon has rock entry points such as Bay Marchand 3, Pelican Island Reef and South Timbalier 86. Rig-diving gateway: reefed platforms just offshore hold snapper and cobia, while Timbalier Bay is sheltered and silty. Below you'll find each spot (access, shelter and hazards) and today's forecast.

    When is the best season in Port Fourchon?

    Apr–Oct; rig-diving (rigs-to-reef) culture in federal waters.

    How cold is the water in Port Fourchon?

    The Mississippi plume clouds the coast; clear 22–29 °C on the far rigs.

    Is Port Fourchon good for a beginner?

    Advanced: serious hunting on the far rigs; plume-murky nearshore.

    Do I need a licence in Port Fourchon?

    Yes — in Port Fourchon 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.
