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.

⚠️ This point is inside the restricted zone “Biotopo Protegido Deba-Zumaia — Zona de Protección Marina (pesca no prohibida por el decreto)”: 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 Deba bar empties right alongside: on an ebb with the river up the water leaves turbid and fast.
shelter
Nothing in front and a wall behind: with a north-west groundswell there is nowhere to tuck in.
conditions
Wall and slabs from 5 to 14 m; the cleanest water in the municipality, 7-9 m, because the Deba is 1.3 km west.
hazard
IT IS INSIDE the biotope's Zona de Protección Marina (3,520 ha, out to the internal-waters line): Decreto 33/2009 does NOT forbid fishing in it. What is banned outright is the Zona de Reserva, and it starts 101 m east of this mark — one minute of finning. Look at the map before drifting that way, because the ebb sets exactly in that direction.
access
The flysch path to the end of the open stretch, 1.4 km from the beach, and down through the cleft.

    tide
    Cantabrian regime, spring range up to 4.5 m. On the flood the clean water comes up the gullies, and that is the good hour.
    shelter
    The point cuts the north-west just enough to leave the south side fishable with under a metre of sea.
    conditions
    Boulders and sand from 3 to 11 m; the Deba stains the whole stretch on every spate and takes two or three days to clear.

    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 Deba

    Where can I spearfish in Deba?

    Deba has rock entry points such as Ondarbeltz — punta oeste, Flysch de Deba (este de Santiago) and Lapari. Deba lies inside the Deba-Zumaia biotope. Below you'll find each spot (access, shelter and hazards) and today's forecast.

    When is the best season in Deba?

    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 Deba?

    ~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 Deba 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 Deba?

    Yes — in Deba 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.
