Compiled by the spearo sea-state engine · How it works →

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.

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.

AlkoleaMutriku
no data
window
—
tide
Cantabrian regime, spring range up to 4.5 m. The exit ledge covers at half-tide: work out the way back before you get in.
shelter
The platform shelters nothing: the whole 300-40° sector comes in and only a south land wind leaves it fishable.
conditions
Gullies from 3 to 9 m over slab; on a clean southerly you see 7-9 m, the best water in the municipality.
hazard
Nearest bathing zone (Ondar Gain) 821 m away and the inner harbour 257 m: this mark is clear of everything. The risk is the platform itself — slick slab, sweeping waves and a hard exit at high water.
access
Park on the Deba road and walk down the track to the platform; in via the central gully.

Flysch platform between Mutriku and Arbe; gullies running square to the shore, good visibility on a southerly. No bathing zone within 800 m.

    tide
    Cantabrian regime, spring range up to 4.5 m. The cobbles roll with every wave at high water and make the exit harder than the entry.
    shelter
    The point cuts the east and the cove keeps one fishable corner on a north-easterly.
    conditions
    Boulder field from 5 to 12 m with dense kelp; 6-8 m of visibility and the best fish on this stretch.
    hazard
    Clear of every zone: nearest bathing zone (Ondarbeltz) 735 m, the harbour 739 m and the Zona de Reserva 1.6 km east — mind that if you swim that way, because fishing there is banned outright. An outgoing current runs off the point on the ebb.
    access
    Track to the edge of Arbe and a short scramble down; in at the south corner of the cove.

    Cove and point east of town; boulders and kelp at 5-12 m, one of the reference marks of the area. 1.6 km from the biotope's Zona de Reserva.

    ⚠️ This point is inside the restricted zone “Zona de baño censada «Mutriku (Ondar Gain)» (Mutriku) + 250 m — pesca submarina prohibida (art. 14.3, Decreto 198/2000), 1 jun – 30 sep”: fishing there is regulated (season, gear, permit), not banned outright. Read the zone's rules before you go.
    window
    —
    tide
    Cantabrian regime, spring range up to 4.5 m. The stacks can be walked round only at low water; on a rising tide you swim back.
    shelter
    The coves are open to the north; only the east flank of each gives any lee on a westerly.
    conditions
    Slab and cave from 2 to 8 m, shallow; with any groundswell the beach sand clouds the lot.
    hazard
    The censused Ondar Gain bathing zone is 75 m away — INSIDE the 250 m of art. 14.3, so from 1 June to 30 September this mark is not fished; it stays published because the rest of the year it is legal, good water. The outer dock of the harbour is 65 m south-west. censused bathing zone — from 1 Jun to 30 Sep art. 14.3 of Decreto 198/2000 bars spearfishing inside it and within 250 m port water: art. 18.2.2 of Decreto 198/2000 closes ports, docks, anchorages and channels all year
    access
    From Burumendi beach over the rocks at the east end, 100 m; at high water you walk straight in.

    Rocky flanks of the eastern coves; flysch slabs and shallow caves, entry off the beach. 75 m from the Ondar Gain bathing zone: in season this mark is not fishable.

    tide
    Cantabrian regime, spring range up to 4.5 m. On a spring low the cove is left ankle-deep and there is nothing to hunt until half-tide.
    shelter
    Each cove is a different lee: on a westerly you fish the third, on a north-easterly the sixth.
    conditions
    Vertical wall from 4 to 18 m; the deepest shore-accessible water in Mutriku, with 6-9 m of visibility.
    hazard
    Clear of every mapped zone: Saturraran 1.3 km and the harbour 1.4 km. The danger is the cliff — no exit between coves, no signal, and the path cut by rockfall in winter.
    access
    Coast path west from Mutriku, 25 minutes, and down a fixed rope into the third cove.

    Idurrepe's seven coves west of the harbour; flysch cliff, reachable only by swimming or footpath, and 1.3 km to the nearest bathing zone.

    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
    • ✓Spearfishing licence mandatory; the AUTONOMOUS COMMUNITY issues it (not the State) and it is valid in the exterior waters of the whole coast. Free-diving only — scuba is banned (, art. 3).
    • ✓Spearfishing catch may not be sold or traded — it is non-commercial fishing ().
    • ✓Night prohibited: spearfishing only in daylight (sunset to sunrise not allowed) — , art. 16.d.
    • ✓Marker buoy MANDATORY: mark your position with a clearly visible buoy and stay within 25 m of it — , art. 15.
    • ✓Never keep the speargun loaded out of the water — , art. 16.a.
    • ✓Keep at least 300 m from professional fishing vessels that are working — , art. 12.b.
    • ✓The state act (, art. 16) bans, for spearfishing: a loaded gun out of the water; explosive/electric points and lamps (hand torches excepted); underwater scooters; night — from sunset to sunrise. Plus art. 12 b), d), e): 300 m from professional fishing vessels, light as an attractant, poisons/explosives. A ban in a PARTICULAR reserve, port or beach comes from that place's OWN instrument (the reserve's order, the autonomous community's rules, the port authority) — see the no-take zones on the map and your community's rules.
    • ✓Min. sizes by ( + + EU 2019/1241): sea bass 42 cm (rec.) / 36 cm / 25 cm Mediterranean / 22 cm Canaries; gilthead bream 20 cm and white seabream 23 cm in the Mediterranean (EU 2019/1241); grouper 45 cm. See your zone's species card.
    • ✓Only species in Annex I of may be taken; keeping, landing or transporting undersized specimens is prohibited.
    • ✓The licence needs a medical fitness certificate for free-diving and civil-liability insurance (or a federative licence, which includes it). Mandatory in the Basque Country/Murcia/Asturias/Galicia; the federative licence covers it in Galicia/Balearics/Cantabria; the Canaries and Andalusia do NOT require it for the individual licence (a responsible health declaration). Minimum age generally 16 (14 in Andalusia).
    • ✓There is no fixed national catch cap (, art. 5 delegates it to the communities); the standard is 5 kg/person/day, with 1 specimen allowed not to count (Canaries — Decreto 182/2004, art. 38.3; Murcia; Galicia; Basque Country). Protected species have per-piece quotas.
    • ✓Only a harpoon is allowed — hand-held or mechanically propelled, with one or several points (, art. 14.1). Carrying spearfishing gear and underwater breathing equipment aboard AT THE SAME TIME is prohibited (art. 14.2) — an offence in itself, even if you dived on a breath hold.
    • ✓Spain is not one jurisdiction. The licence is issued by a coastal autonomous community, and you must comply with the rules of the administration on whose littoral you are in the water: «debiendo cumplir la normativa establecida por la administración en cuyo litoral se realice la actividad» (, art. 13). Interior waters — inside the straight baselines: bays, coves, rías, the whole coastal strip — are the community's competence; exterior waters are the State's. So the age, the days of the week, the distances and the are found in your community's act, not in the state one.
    • ✓Basque Country: the spearfishing licence is issued by the Basque Government — Gobierno Vasco (Eusko Jaurlaritza): Decreto 198/2000, platform, spearfishing valid 1 year.
    • ✓Basque Country: spearfishing needs a SEPARATE licence (Decreto 198/2000, art. 4); it takes being 16, an official sports medical certificate of fitness for this very activity, and accident + civil-liability insurance (art. 7.3). The cap is 5 kg (art. 12.1). Barred within 250 m of properly delimited bathing or watersport areas (art. 14.3); orto to ocaso only (art. 16). Ports, docks, habitual anchorages, navigation channels and vessel-traffic zones are closed; and a biotope, a special-protection zone or an artificial reef closes spearfishing only when ITS OWN norm says so (art. 18).
    • ⛔ Seahorses (Hippocampus) — protected (RPE).

    Rules change and are REGIONAL. Before heading out, check with the competent autonomous community (licence) and the min-size table in force.

    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 Mutriku

    Where can I spearfish in Mutriku?

    Mutriku has rock entry points such as Burumendi eta Hirugarren hondartza, Alkolea and Arbe eta Arrilabango punta. Mutriku is the doorway to the flysch: slabs, gullies and coves east of town, and Idurrepe's seven coves to the west, reached only by swimming or by path. Below you'll find each spot (access, shelter and hazards) and today's forecast.

    When is the best season in Mutriku?

    Summer and early autumn are the windows — in winter the Bay of Biscay swell shuts the coast down. Tides are large (4 m+) and set up current, so pick a small-sea day with the tide in your favour.

    How cold is the water in Mutriku?

    ~14–22 °C: cool, but it warms up in the summer window. A 5 mm suit at peak summer, 7 mm with a hood the rest of the year.

    Is Mutriku good for a beginner?

    Demanding: strong Biscay swell, big tides and exposed rock entries. It's for those who can already read the sea and pick the window well — not a coast to start on.

    Do I need a licence in Mutriku?

    Yes — in Mutriku you need a recreational sea-fishing licence (issued by the autonomous community); breath-hold only (no scuba), with a marker buoy and no night diving. See the guide.
