Compiled by the spearo sea-state engine · How it works →
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: 1391 spots across 205 stretches of coast — mainland Portugal, Madeira and the Azores.
State-deployed recreational reef in 17 m of water, roughly 3 km off Bunbury: thirty concrete boxes of three metres in six clusters, with ninety smaller modules added in 2019. Boat only. No Western Australian marine park reaches these waters — the nearest is over 30 km south.
Purpose-scuttled dive wreck of December 2003, sunk in 17 m about three nautical miles off Back Beach and well outside the port. The museum record lists her as not federally protected, so no heritage exclusion applies; the position matches the museum and the wreck guide to four decimals.
The ocean end of Bunbury's Back Beach strip, taken 85 m off the shoreline. This frontage is dead straight — the seaward normal holds 285–288° over 1.5, 3 and 5 km — so anything from the west quarter lands on it unfiltered and there is no corner to hide in. Sand with rock at the ends; a small, clean day only.
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.
One morning glance — and you know.

Law
•Spearfishing in Australia is governed by STATE law, not federal: the licence, the gear, the closed areas, the sizes and the all differ between NSW, QLD, VIC, SA, WA and TAS. Below is your state's pack; cross into the next state and the rules change at the border.
✓Federally listed species are protected everywhere in Australia, in every state and in Commonwealth waters: white and whale sharks, sawfish, marine turtles, marine mammals and the other listed marine species — never shoot, disturb or take them (Environment Protection and Biodiversity Conservation Act 1999).
•Marine park zoning applies ON TOP of the state's fishing rules: / Sanctuary / Preservation zones are full no-take, and on the Great Barrier Reef the marine park zoning sits on top of the Queensland rules. Check the boundaries on the managing agency's zone map before you enter the water.
•Two prohibitions coincide in every state we ship a city in: rock lobster may not be taken with a spear or any puncturing device, and all inland (fresh) waters are closed to spearfishing. Abalone may not be speared either. Source: the state fisheries recreational guides.
✓WA: no licence is needed for shore-based fishing, but from a powered boat a Recreational Fishing from Boat Licence is required — AUD 40 a year; separate rock lobster and abalone licences at AUD 50. Half fee for under-16s, Seniors Card holders and listed pensioners; a licence runs 12 months from issue (Fish Resources Management Act 1994).
✓WA gear and places (per DPIRD, 2026 guide): spearfishing is allowed in ocean waters except some , around dive wrecks, and from a boat during the West Coast demersal closure. All inland waters are closed; a hand spear in an is only for estuarine cobbler. In Ningaloo and Shark Bay Marine Parks spearfishing on compressed air is prohibited. A is not on the list of permitted gear, and explosives or noxious substances may not be carried on a boat (Aquatic Resources Management Act 2016).
•WA, the key shore-versus-boat difference: the demersal closure in the West Coast bioregion (Kalbarri/Zuytdorp – Augusta/Black Point) runs to spring 2027 and bites on BOAT-based fishing, boat spearing included; shore-entry spearfishing stays open. The exception is the dhufish, which may not be speared from land at all. The South Coast bioregion (Albany, Esperance) is outside the closure.
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 Bunbury
Where can I spearfish in Bunbury?
Bunbury has rock entry points such as Mindalong Beach, Bunbury Artificial Reef and Lena. Two coasts in one town: Koombana Bay and the Leschenault Inlet face north behind the port, while the Back Beach strip faces 289° straight into the Indian Ocean swell. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Bunbury is in WA. No licence from the shore in Western Australia — but fishing from a boat needs the RFBL, and the WA dhufish sits under a demersal closure to spring 2027. Spearfishing on scuba is banned everywhere, rock lobster may never be speared, and marine-park sanctuary/green zones are no-take. See the guide for the state-by-state detail.
•WA sizes and seasons: pink snapper 50 cm (Lancelin – Black Point) or 41 cm (Lancelin – Zuytdorp), bag 2; western blue groper 50 cm (1); coral trout 45 cm (1); spangled emperor 40 cm; WA salmon 30 cm (4) and tailor 30 cm (8) inside the 16-fish nearshore bag. Closures: Cockburn and Warnbro Sounds 1 Aug – 31 Jan, the Abrolhos baldchin groper closure 1 Oct – 31 Dec, and three separate Shark Bay pink snapper windows.
•WA weather: the BOM marine wind warning summary for the state — bom.gov.au/marine/lite/warning/IDW20100.shtml. Rules change: check DPIRD before every trip.
⛔ 🚫 Western Australia also protects all rays and skates in the Hamelin Bay Protection Area, the black and smooth stingrays (Bathytoshia) in the South Coast and West Coast bioregions, coral and live rock, and seven native freshwater fishes (fresh water is closed to spearfishing anyway).
⛔ 🚫 Fully protected in Western Australia: grey nurse shark, white shark, speartooth shark, whale shark, all sawfish, potato rockcod, Queensland groper, humphead Maori wrasse, common and leafy seadragons, coral and live rock; black and smooth stingrays in the South Coast and West Coast bioregions.
⛔ 🚫 Every inland water in Western Australia is closed to spearfishing; some and the dive wrecks are closed to it, and in Ningaloo and Shark Bay Marine Parks spearfishing on compressed air is prohibited (DPIRD). Rock lobster and abalone may not be speared.
Rules change and vary BY STATE. Before heading out, check with your state's fisheries (NSW DPI, Fisheries QLD, VFA, DPIRD WA, PIRSA, NRE Tas, NT Fisheries) and the marine-park zoning map.
