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.

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: 1391 spots across 205 stretches of coast — mainland Portugal, Madeira and the Azores.
The cape that closes Varazze to the west, where the seafront promenade ends and the rock towards Celle begins: serpentinite slabs running into the water and carrying on down, boulders and vertical fissures, patchy posidonia along the sand edge. This is the deep ground of the coast — 400 m out EMODnet reads −18.4 m, three times Arenzano — so grouper here is not a figure of speech and dentex pass through. Close in: octopus among the boulders, sargo and saddled bream on the points, gilthead along the sand edge. It faces SOUTH-EAST: a libeccio breaks along the whole point and you see nothing, a tramontana settles it and it clears in half a day. Boat traffic to the marina — float in sight, always.
Two kilometres east of the marina, where road and railway pull away from the sea and the shore becomes unbroken rock all the way to Punta d'Invrea: serpentinite steps, slides of big boulders, and a bottom that drops away fast. It is the deepest number in the whole wave — 400 m out EMODnet reads −22.4 m. Grouper in the deeper cracks in summer, dentex and amberjack passing, sargo and saddled bream along the whole step, octopus under the boulders. It faces SOUTH-EAST and it is EXPOSED: there is no shelter here, the libeccio comes straight in and the current works along the rock. Access on foot from the coast path — do not go in alone, and plan the exit before the entry.
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.
One morning glance — and you know.

Law
✓NO paid licence, but a free MASAF REGISTRATION is mandatory (recreational sea-fishing declaration, online via SIAN/SPID, annual) — it is not a «licence».
✓Free-diving only: scuba/rebreather/hookah BANNED (art. 128-bis DPR 1639/68). The 16+ rule comes from a different act — D.Lgs 4/2012, art. 6 c. 5; handing a speargun to an under-16 is an offence (art. 13-octies c. 3 b, as replaced by L. 75/2026).
✓Night prohibited: spearfishing only from dawn to sunset (art. 129e DPR 1639/68).
✓Distances (art. 129 DPR 1639/68): ≥500 m from beaches with bathers; ≥100 m from fixed gear/set nets and from vessels anchored outside ports.
✓Buoy MANDATORY (art. 130 DPR 1639/68): float with a red flag bearing a white diagonal stripe, visible ≥300 m; the diver stays within 50 m of the buoy/support boat.
✓The speargun may not be kept armed out of the water (art. 131 DPR 1639/68) — load only when submerged.
✓The spearfisher may NOT gather corals, crustaceans or molluscs — the second paragraph of the same article (art. 128-bis DPR 1639/68; the same rule in D.M. 249/1987, art. 2). BUT cephalopods are EXCLUDED: octopus, cuttlefish and squid may be taken — the exception is kept in terms by the official guidance (circolare 6227201 of 23.07.1987). Mussels — up to 3 kg per person per day, but only with the Capo del Compartimento Marittimo's authorisation. The 5 kg daily cap counts EVERYTHING taken that day (D.Lgs 4/2012, art. 13-octies c. 4, as replaced by L. 75/2026).
✓You MAY carry a speargun and a breathing apparatus on the same boat — but at most ONE cylinder of up to 10 L per vessel, and using it to fish is prohibited (art. 128-ter DPR 1639/68). While you are down, at least one person must stay aboard ready to intervene, and there must be a rope long enough to recover the diver.
✓Sale of recreational catch is PROHIBITED (EU control regime, Reg. CE 1224/2009).
✓The 5 kg/person daily cap IS in force and carries a fine: €500–3 000 up to 10 kg, €2 000–12 000 up to 50 kg, €12 000–50 000 above (D.Lgs 4/2012, art. 13-octies c. 4, as replaced by Law 21 Apr 2026 no. 75). Exception: a single fish heavier than 5 kg. Recovery-plan species and bluefin tuna: +1/3 (c. 5).
⛔ Date mussels (Lithophaga lithophaga) — TOTAL BAN: fishing, possession, transport, sale (D.M. 16/10/1998; EU-protected). Never touch.
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 Varazze
Where can I spearfish in Varazze?
Varazze has rock entry points such as Punta dell'Olmo and Punta della Mola. Spearfishing in Varazze: sea forecast and shore-entry spots. Below you'll find each spot (access, shelter and hazards) and today's forecast.
When is the best season in Varazze?
A Mediterranean season from late spring to autumn, peaking in summer. It opens when the SW libeccio eases and the water clears; morning or an offshore wind is the best moment.
How cold is the water in Varazze?
Mediterranean: ~13 °C in winter up to ~24–25 °C in summer. A 3 mm suit in high summer, 5 mm in spring and autumn; the thermocline can leave the bottom colder.
Is Varazze good for a beginner?
Intermediate: rock and cliffs with quick drop-offs, often deep close in. On calm days it's approachable in the sheltered corners; with libeccio it's for the experienced. Buoy always.
Do I need a licence in Varazze?
No — in Varazze there is no paid licence; a free MASAF declaration is mandatory (the recreational sea-fishing communication, online via SIAN/SPID, renewed each year), which is not a «licence». Breath-hold only (no scuba), with a marker buoy and no selling the catch. See the guide.
Rules change. Before heading out, check with MASAF (registration) and the Guardia Costiera / Capitaneria di Porto; Sicily and Sardegna add regional tightening.
