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.

  • 🚫 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 Byron Bay: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Spearfishing in Byron Bay is a zoning-first plan. Cape Byron Marine Park wraps the headland, and sanctuary zones mean no fishing or spearfishing. Julian Rocks and The Pass are no-take for hunting purposes, so treat any uncertain boundary as closed. The practical shore dive is Tallow Beach at Cosy Corner, where rock and reef hold drummer, bream and snapper when the shore break is small. NSW rules apply: pay the Recreational Fishing Fee, follow current limits and release protected species.

TL;DR

  • Byron Bay starts with zoning: Julian Rocks and The Pass are treated as Cape Byron Marine Park sanctuary closures.
  • The practical legal shore option is Tallow Beach, Cosy Corner, only with small shore break and settled easterly swell.
  • Clearer water usually follows light offshore wind and calm days; E to SE swell dirties the rocks fast.
  • In NSW, pay the Recreational Fishing Fee, follow current limits and never spear eastern blue groper.

Key Byron Bay spearfishing locations and closures

Byron rewards conservative map work. Famous dive names are not automatically hunting spots, because sanctuary water sits close to town. Use the marine park map, keep a wide buffer from the line, and choose entries that are clearly outside no-take water.

SpotTypeDepthLevelAccessNotes
The PassSanctuary-side reef and sand cornerShallow reef and sand edgeClosed when inside sanctuary waterBeach and headland access under Cape ByronA sheltered corner for swimmers and snorkellers, not a default spearfishing mark. The Pass sits inside sanctuary water, so do not hunt there unless an official map proves otherwise.
Tallow Beach - Cosy CornerRock, boulder and reef shore diveMostly shallow reef, around 2-8 mIntermediate shore entryWalk in from the southern end of Tallow BeachThe realistic legal option in this group. Expect drummer, bream and snapper around the rock edge after calm weather. Any easterly shore break makes the return messy.
Julian Rocks (Nguthungulli)Offshore reef sanctuaryBoat dive reef, roughly 2.5 km offshoreNo-take closure for spearfishingBoat access for diving, not huntingA landmark dive site with grey nurse sharks and turtles. It is a Cape Byron Marine Park sanctuary zone, so spearfishing is prohibited.

When does Byron Bay visibility usually work?

The Byron coast faces the easterly swell corridor, so water quality changes quickly. Small swell, light westerly wind and a few settled days are the useful signs. An E or SE push puts sand and bubbles around Cosy Corner and makes the rock exit less forgiving. After rain, wait for the nearshore water to settle rather than guessing from the car park.

Which Byron zones are closed to spearfishing?

Cape Byron Marine Park is the main legal filter. Sanctuary zones are no-take: no fishing, no spearfishing and no collecting. The city centre warning, The Pass and Julian Rocks all point to hard closure risk. Boundaries can be hard to judge from the water, so leave a generous buffer. If a GPS point, sign or map does not agree, stay out.

What fish are realistic around Byron Bay?

On legal reef outside sanctuary water, expect east-coast temperate species rather than a long offshore trophy list. Drummer and bream work the wash, snapper move around broken reef, and yellowtail kingfish can appear when the water is blue enough. NSW size and bag limits decide the keepers. Eastern blue groper, black cod, grey nurse shark and white shark must not be taken.

What NSW rules matter before a shore dive?

A NSW Recreational Fishing Fee is required unless an exemption applies. Carry proof, know the current bag and size table, and check marine park zoning before entering. Spearfishing is banned in inland waters, and protected species must be released immediately. Do not load a speargun around people or out of the water. If the clean water is inside a sanctuary, snorkel or wait.

FAQ

Do you need to pay the NSW fishing fee to spearfish in Byron Bay?

Yes. Spearfishing is recreational fishing in NSW, so the Recreational Fishing Fee applies unless you qualify for an exemption.

Can you spearfish at Julian Rocks?

No. Julian Rocks is treated as a Cape Byron Marine Park sanctuary site, which means no fishing and no spearfishing.

Is The Pass a safe spearfishing spot?

No for hunting when it falls inside sanctuary water. Use the official map and fail closed if the boundary is uncertain.

How is Byron Bay visibility after easterly swell?

Usually poorer. The exposed coast stirs quickly in E to SE swell, so wait for small swell, offshore wind and settled water.

Is eastern blue groper legal to spear in NSW?

No. Treat eastern blue groper as fully protected from spearfishing and release it immediately if encountered.
