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.

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: 3016 spots across 406 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.

  • red / spiny rock lobster (kōura)
    Jasus edwardsii · 3–30 m · ⚠️ closed season/limit
    tail width ≥ 54 mm (♀ 60 mm) · bag 6 a day · 🚫 no spear · 🚫 possessing a speared one is an offence · ✋ by hand or hand-operated loop (spring-loaded loops banned) · The six is spiny and packhorse combined, of which at most 3 packhorse. · Measure tail WIDTH: male 54 mm, female 60 mm; berried, soft-shell and unmeasurable ones go straight back. (Fisheries (Amateur Fishing) Regulations 2013, reg. 29(2), reg. 46; MPI 7281.)
  • pāua (blackfoot abalone)
    Haliotis iris · 0–10 m · ⚠️ closed season/limit
    min 125 mm (shell) · bag 5 a day · ✋ by hand · tool: pāua knife (blunt; MPI: never use sharp objects) · Inside the Taranaki pāua fishery area the minimum is 85 mm, not 125 mm. · 🚫 Pāua is free-diving only: with underwater breathing apparatus you may neither take nor possess it — having a tank in the vehicle or on the boat while holding pāua is already an offence (Fisheries (Amateur Fishing) Regulations 2013, reg. 48). A snorkel does not count as apparatus. · ⚠️ Before taking any shellfish check the NZ Food Safety biotoxin warnings — they change constantly and are separate from the fishing rules.
  • kina (sea urchin)
    Evechinus chloroticus · 1–15 m · legal
    no minimum size · bag 50 a day · ⚠️ Before taking any shellfish check the NZ Food Safety biotoxin warnings — they change constantly and are separate from the fishing rules.
  • trumpeter (kohikohi)
    Latris lineata · 10–60 m · legal
    min 35 cm · inside the combined limit 20 · Almost always sits below safe breath-hold depth — on this coast it is information, not a target.
  • hāpuku / bass (groper)
    Polyprion oxygeneios · 30–120 m · ⚠️ closed season/limit
    no minimum size · bag 2 a day · inside the combined limit 20 · No more than 3 per fisher accumulated over more than one day. · Almost always sits below safe breath-hold depth — on this coast it is information, not a target.

    • Law
    • ✓There is no in New Zealand: MPI states plainly that you do not need one to fish in the sea — only fresh water needs a licence. The rules are REGIONAL, though: MPI divides the country into seven fishing areas with their own sizes and limits, and the Kaikōura Marine Area has rules of its own on top. Buying, selling or swapping recreationally caught seafood is an offence under the Fisheries Act 1996.
    • ✓Three species may not be taken with a SPEAR anywhere in the country: rock lobster, salmon and trout. For rock lobster it is an express rule — using a spear to take one, and possessing a speared lobster, are both prohibited, with a fine up to NZ$10,000 (Fisheries (Amateur Fishing) Regulations 2013, reg. 29(2)). Salmon and trout are freshwater sports fish managed by Fish & Game.
    • ✓AN IMPORTANT CORRECTION to a common belief: no nationwide scuba ban for spearfishing was found in the MPI rules. The only breathing-apparatus prohibition is for PĀUA: it may be neither taken nor possessed while you have apparatus, even if the tank is merely in the car or on the boat (Fisheries (Amateur Fishing) Regulations 2013, reg. 48). A snorkel is not apparatus, and what forbids rock lobster is the SPEAR, not the tank. An absence of prohibition is not a permission: ask MPI before you go.
    • ✓: MPI describes spearfishing as catching fish with rubber-powered spearguns and slings or compressed-gas pneumatic spearguns, and its rules say neither yes nor no about or explosive tips. Treat the question as UNRESOLVED and do not carry a as permitted gear. No time-of-day restriction was found in the MPI rules or in the Fisheries (Amateur Fishing) Regulations 2013.
    • ✓How to measure and where to check: a finfish is measured from the tip of the nose to the end of the middle ray of the tail fin — the 'V' of the tail, not its tips (Fisheries (Amateur Fishing) Regulations 2013). Rock lobster is measured by tail WIDTH; pāua along the flat face of the shell in a straight line, not over the curve. Rules change often: MPI asks you to check them each time before you go fishing, for example in the NZ Fishing Rules app. Poaching: 0800 4 POACHER.
    • ✓Central: combined finfish daily limit 20, snapper 10 at 27 cm. Blue cod is split in two: 8 (Taranaki – Titahi Bay) 2 a day, 2 (Titahi Bay – Cape Runaway) 20 a day, min 33 cm. Pāua 5 a day at 125 mm — but 85 mm inside the Taranaki pāua fishery area. Rock lobster south of the Wairoa: 6 combined, max 3 packhorse. Waimārama is closed to blackfoot pāua until 22 December 2026, and Pukerua Bay is hand-held lines only (MPI; Fisheries (Recreational Management Controls) Notice No. 1 2026).
    • •Weather: MetService coastal forecasts and gale warnings — metservice.com/marine/coastal, areas: portland, castlepoint, cook, stephens, raglan. Fishing rules change: check MPI or the NZ Fishing Rules app before every trip.
    • ⛔ 🚫 Absolutely protected under the Wildlife Act 1953: white, basking, whale, oceanic whitetip and smalltooth sandtiger sharks, oceanic manta and spinetail devil rays, giant grouper and spotted black grouper, plus black corals, gorgonians, stony corals and hydrocorals. Marine mammals sit under the Marine Mammals Protection Act 1978. Penalty up to NZ$250,000 and six months.
    • ⛔ 🚫 Marine reserves (Marine Reserves Act 1971) are total no-take by any method, spearfishing included; so are areas protected under the Conservation Act 1987. and run on their own bylaws, and a is a temporary closure under the Fisheries Act 1996 with a real fine as well as a tapu. Check local bylaws and current before you go — they change several times a year.
    • ⛔ 🚫 Pukerua Bay is closed to everything but hand-held lines — which kills spearfishing there. Waimārama (Hawke's Bay) is closed to blackfoot pāua until 22 December 2026, supporting the of Ngāi Hapū o Waimārama. Six marine reserves — Kāpiti (eastern and western), Tapuae, Taputeranga, Te Angiangi and Te Tapuwae o Rongokako — are closed to all fishing.

    Rules change and are regional. Before heading out, check with MPI (regional fishing rules / the NZ Fishing Rules app), DOC (marine reserves) and local notices (rāhui/mātaitai).

    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 Māhia

    Where can I spearfish in Māhia?

    Māhia has rock entry points such as Tuahuru Point, Putiki Point and Tawapata Bay. Māhia is a hamlet in the Hawke's Bay region, and its own water belongs to the Horokaka mātaitai reserve, a customary fisheries area with its own local rules; that is not a ban in itself. Below you'll find each spot (access, shelter and hazards) and today's forecast.

    When is the best season in Māhia?

    Summer (Dec–Apr) — open shingle coast; catch the calms.

    How cold is the water in Māhia?

    Summer 16–20 °C — 5 mm suit; open shingle coast.

    Is Māhia good for a beginner?

    Moderate: open coast; catch the calms.

    Do I need a licence in Māhia?

    No — New Zealand has no recreational sea-fishing licence, so anyone may spearfish at Māhia; MPI's size, bag and gear rules still apply and they are set per MPI fishing area: Māhia is in the Central area, where the combined finfish daily limit is 20. Pāua is free-dive only — having underwater breathing apparatus while taking pāua is banned nationwide — crayfish (rock lobster) may be taken only by hand or a hand-held loop, never speared — MPI's rules set no scuba ban for crayfish; spearfishing is banned inside every marine reserve, and mātaitai, taiāpure and rāhui must be respected. See the guide.
