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.

The water column

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.

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.

Law
  • 🚫 Eastern blue groper (NSW state fish) — protected from spearing since 1969. Potato cod, Queensland (giant) groper, humphead Maori wrasse, barramundi cod — no-take.
  • 🚫 Grey nurse shark, black cod (Epinephelus daemelii), great white shark, whale shark, seahorses/seadragons — fully protected.
  • 🚫 Rock lobster may NOT be taken by spear (statewide gear rule). Spearfishing is banned in all inland waters and in / (full no-take) — check the zone map.
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 Augusta (Flinders Bay): spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Spearfishing in Augusta is a contrast between bay water and exposed cape water. Flinders Bay by the boat harbour is the easiest listed entry, with shallow reef in 2-8 m. Hamelin Bay can be a legal shore entry outside the Ngari Capes sanctuary line, but the boundary needs a local check. Cape Leeuwin is the dramatic option and the least forgiving: 4-12 m reef, Southern Ocean swell and high shark-risk warnings.

TL;DR

  • Augusta is a WA south-west edge: Flinders Bay can be manageable, while Cape Leeuwin belongs to rare calm days.
  • Hamelin Bay is usable only with zoning discipline. Ngari Capes sanctuary water sits at Hamelin Island reef to the west.
  • WA has no general shore licence under Australian state-by-state rules, but boat RFBL, DPIRD limits and demersal closures can still change the plan.
  • The worst weather is southerly ocean energy around 190 degrees. If the Southern Ocean is showing power, do not force the cape.

Which Augusta shore entries are realistic?

Sort by exposure before fish. The bay gives room to decline a dive; the cape gives fewer second chances.

Cape LeeuwinExposed lighthouse cape reef4-12 mAdvanced, calm days onlyRock entry with a pre-planned exit and no swell surpriseDhufish habitat appears in the note, but so do Southern Ocean exposure and high shark risk.

What weather window does Augusta need?

The coastline faces south, and the bad sector runs roughly 130 to 250 degrees. A west wind can help Flinders Bay, but it does not make Cape Leeuwin friendly when long-period swell is present. Read the bay first and leave the cape for exceptional days.

How should Ngari Capes zoning be treated?

Fail closed. Hamelin Bay is described as legal outside the sanctuary, while Hamelin Island reef to the west is named as the sanctuary reference. That wording makes the boundary part of the dive plan. If DBCA or DPIRD mapping is unclear, skip it.

What WA rules affect Augusta catches?

WA has no general recreational shore licence under Australian state-by-state rules, but boat activity can require the RFBL. DPIRD size and bag limits apply. West-coast demersal settings matter for dhufish and related bottom fish, with a closure noted through spring 2027 for that bioregion.

What are the main safety cues?

The city notes mention high shark risk at the cape and stingrays at Hamelin Bay boat ramp. Add the AU gear rule that rock lobster may not be speared. Fish clear shallow reef, avoid long bloody tows, and save crustaceans for legal non-spear methods.

FAQ

Do you need a licence to spearfish in Augusta WA?

There is no general WA shore licence under Australian state-by-state rules, but RFBL, DPIRD limits and closures may apply.

Can you spearfish at Hamelin Bay?

Only outside sanctuary water. Verify the Ngari Capes boundary.

Is Cape Leeuwin suitable for beginners?

No. It is exposed to Southern Ocean swell and high shark risk.

Can you spear dhufish near Augusta?

Check current DPIRD demersal rules first.

Can rock lobster be taken with a spear?

No. Australian state-by-state rules say rock lobster may not be speared.
