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.

  • 🚫 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 Hobart / D'Entrecasteaux: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Spearfishing near Hobart works best when the plan separates closed reserve water from ordinary shore reef. Tinderbox is famous for diving but it is a Marine Reserve, so do not spear there. Blackmans Bay gives a legal reef and point option in moderate depth, while Taroona and Hinsby Beach are sheltered Derwent entries with easier access and often softer visibility. Tasmania rules are species and method specific: check scalefish limits, protected species and marine reserve boundaries before packing extra gear.

TL;DR

  • Hobart spearfishing is sheltered by Tasmanian standards, but Tinderbox Marine Reserve is no-take and must stay look-only.
  • Blackmans Bay is the stronger shore choice; Taroona and Hinsby Beach are easy but often lower visibility in the Derwent.
  • Expect cold water, reef ledges, kelp, flathead ground and suburban boat traffic rather than open-ocean bluewater hunting.
  • Check Fishing Tasmania rules for scalefish limits, protected species and marine reserves.

Hobart shore spearfishing entries and closures

Hobart is forgiving compared with the Tasman Peninsula, but it has more suburban traffic and more reserve traps. Treat Tinderbox as a closed dive site, then judge Blackmans Bay and Taroona by visibility, wind and boat movement. A good Hobart session is usually a modest one: short swim, visible float and a clean exit.

SpotTypeDepthLevelAccessNotes
TinderboxMarine reserve reefShallow reef and weed bedsNo-take closureShore dive site south of HobartA classic snorkel and dive area with boarfish and reef life, but not a spearfishing spot. The reserve rule is simple: no fishing or setting gear. Keep the gun out of the plan.
Blackmans BayPoint reef and blowhole ledgesAbout 3-8 mAccessible intermediateWalk-in around the pointThe main huntable entry in this group. It has reef ledges, wrasse, flathead ground and cray habitat nearby. It is more comfortable on a settled forecast with wind that does not push chop into the bay.
Taroona / Hinsby BeachSheltered Derwent shore reefAbout 2-6 mAccessible, low to moderate visibilityBeach and foreshore walk-inA convenient estuary-side option when ocean entries are too rough. Expect reef ledges, flathead and shellfish habitat, but plan around lower visibility and local boating.

When does Hobart visibility improve?

Hobart visibility is more estuary-influenced than Eaglehawk Neck. Taroona can be calm yet green, especially after rain or wind-driven Derwent movement. Blackmans Bay often gives the better balance of reef and water movement, but it still needs a settled forecast. W wind shelter is useful at Blackmans only if swell and surface chop stay manageable. Cold water is normal, so long rests and a conservative route help.

Can you spearfish at Tinderbox?

No. Tinderbox Marine Reserve is a no-fishing area, and spearfishing is prohibited. It is fine as a look-only dive if conditions suit, but not as a backup hunting mark. The safe approach is to draw the reserve boundary before the trip, not from memory at the car park. If the cleanest water sits inside Tinderbox, leave it for snorkelling.

What can Hobart divers target legally?

Around open reef, divers may encounter wrasse, flathead, occasional snapper influence and other temperate scalefish. Keepers depend on the current Tasmania size and bag table. Seahorses, weedy seadragons, white sharks and grey nurse sharks are protected.

What local hazards matter most?

Hobart hazards are quieter than cliff-coast hazards, which can make them easier to underestimate. Low visibility, moorings, small boats, cold water and slippery foreshore exits are the usual problems. Carry a high float, stay out of navigation paths and avoid loading a speargun near swimmers. If diving alone, keep the route shallow enough that a missed exit does not become a long cold swim.

FAQ

Do you need a licence to spearfish in Hobart?

Check the method. Scalefish by spear is covered by gear and catch rules, while rock lobster and abalone sit under separate rules.

Can you spearfish in Tinderbox Marine Reserve?

No. Tinderbox is a marine reserve, and fishing or setting gear is prohibited.

Where is the best legal shore option near Hobart?

Blackmans Bay is the strongest listed legal option when swell, wind and visibility line up.

Why is Taroona often murky?

It sits in the Derwent system, so rain, estuary movement and wind chop can reduce visibility even when the surface looks calm.

Are weedy seadragons protected in Tasmania?

Yes. Weedy seadragons and seahorses are protected and must not be taken.
