The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.
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.
Safety gates
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.
Where to get in, where to hunt
Wind, wave and the swell windows — when to go and the best hours.
The day is picked above, in the hero. Here are that day's windows, the hour-by-hour map and the trends. Tap a window to break down the conditions.
Visibility and what drives it — post-storm clearing, river plume, temperature and the thermocline.
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.

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.
Scouted entries, coloured by today. The colour is the sea state at the spot, not a guarantee: the wash and a slippery entry you judge on site.

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.

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.
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.
Sort by exposure before fish. The bay gives room to decline a dive; the cape gives fewer second chances.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Flinders Bay (Augusta) | Sheltered bay reef by the boat harbour | 2-8 m | Best local first check | Shore entry near the harbour when boat movement and visibility allow | Dhufish and skippy are listed, with crayfish habitat. Hunt fish only and keep lobster out of the spear plan. |
| Hamelin Bay | Sheltered bay and reef edges | Variable shallow reef | Intermediate with zoning check | Boat-ramp area and shore access, clear of rays and sanctuary water | Ngari Capes sanctuary water is at Hamelin Island reef to the west. Verify current zoning before loading a gun. |
| Cape Leeuwin | Exposed lighthouse cape reef | 4-12 m | Advanced, calm days only | Rock entry with a pre-planned exit and no swell surprise | Dhufish habitat appears in the note, but so do Southern Ocean exposure and high shark risk. |
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.
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.
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.
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.
There is no general WA shore licence under Australian state-by-state rules, but RFBL, DPIRD limits and closures may apply.
Only outside sanctuary water. Verify the Ngari Capes boundary.
No. It is exposed to Southern Ocean swell and high shark risk.
Check current DPIRD demersal rules first.
No. Australian state-by-state rules say rock lobster may not be speared.
