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 — 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.

Sassi Neri / Due SorelleSirolo-Numana

borderline

swell on the quarter today (city-level)

window: Between the shore and five metres of water there are 410 m: that is the stretch you want to cover in good light. On breath-hold, by day, with the marker in sight: the rest is local variation. With the 410 m that separate you from five metres of water, the return in daylight is planned from the start. At Sirolo-Numana the season conditions the law more than it conditions the sea.
tide: High water pushed by Levante counts for more than a spring tide. At Sirolo-Numana nobody plans an outing around the tide, and they are right not to. Plan on the swell: here it is the only parameter that really changes the day. With the shore 130 m from the mark, the alongshore current counts for more than any table.
shelter: The wall absorbs nothing: what reaches it comes back, and under the rock you get return waves no forecast ever mentions. The shore in front of the mark faces east, about 101°, so everything arriving from that sector gets in unobstructed. The 540 m that separate the shore from ten metres of water tell you how much sea it takes to ruin the day. At Sirolo-Numana the old rule holds: watch the sea for ten minutes, then decide.
conditions: The 20 m contour does not pass within useful reach of this entry: the bottom here stays shallow for a long way. The outside water arrives when the wind from the west pushes it in; with an old sea it stays offshore for days. At Sirolo-Numana the good days are few and have to be taken when they come. In Levante the suspension stays inshore; in Ponente it is gone in half a day.
hazard: Rock coming down from above is a real risk under a cliff, especially after rain. The 500 m from used beaches starts at the water's edge, which is 130 m from here: in summer it is the first calculation to make. Cramp comes at the worst moment: come out before you need to. At Sirolo-Numana the real risk is not the depth: it is the combination of tiredness and swell.
access: Between the coast and the mark there are 130 m of water, to be counted twice, out and back. Under a cliff the access is the real problem: you go down where there is a gully, not wherever you like. If you do not fancy swimming the 540 m back from ten metres of water, do not go any further out. From the entry point to the shore there are 130 m, and they are the metres that weigh most on the return.

Base of the Conero cliff, screes; sea bream, sea bass. Relatively clean water.

Scoglio del TraveSirolo-Numana

borderline

swell on the quarter today (city-level)

window: The 500 m from used beaches is measured from the water's edge, and here the shore is 30 m from the mark: in bathing season do the arithmetic before getting in. With Grecale in the forecast the useful window shortens by itself, long before sunset. In doubt, ask the local Capitaneria beforehand and not afterwards. A shore oriented at 27° loses the sun before sunset: take it into account for the last descent.
tide: The regime is microtidal: the level at Sirolo-Numana moves less than half a metre even at springs. The level counts for little here: what counts is how much sea has gone through in the days before. The way back, 260 m to the five-metre band, is decided beforehand and not on the way. The ten-metre line, 730 m offshore, does not move with the level: it moves with the swell.
shelter: In Grecale the detached rocks break the swell but hand it back confused, and that crossed sea tires you more than a clean wave. With an exposure of 27° the awkward sector runs from north to east, and outside it the day is usually saved. At Sirolo-Numana the swell forecast matters more than the wind forecast on this stretch. With the wind from the southwest at your back you can work; with the swell from the northeast in your face you look and go home.
conditions: In poor clarity at Sirolo-Numana it pays to work short and close to the bottom instead of heading out. With the five-metre band at 260 m and little else, the day is decided entirely by the clarity. By 730 m from the shore you already know whether it is worth going on. Past 730 m from the shore it is the water that decides the day and not the willingness.
hazard: At Sirolo-Numana, as along the whole Italian coast, the surface marker and the 50 m radius are not negotiable. In Grecale the passage between the shoal and the coast becomes the most dangerous part of the route. With 260 m out to five metres, the exit is short only if you decide on it in time. Hypothermia works slowly: you feel it on the way out, not during.
access: With the shore 30 m away and five metres of water at 260 m, the band to cross is a short one. Towards the rock it pays to start from the nearest point of the coast, not from the most comfortable one. The last stretch back to land, 30 m, is always done with less breath than you expected. At Sirolo-Numana the return is planned on the afternoon swell, not on the morning one.

Secca della MadonnaSirolo-Numana

borderline

swell on the quarter today (city-level)

window: DPR 1639/1968 dates from 1968 and is still the reference text: it is not a historical detail. At Sirolo-Numana it is worth losing ten minutes to check the local order rather than arguing about it later. Italian law is the same everywhere; it is the local command that applies it. If there are people in the water the question is not the law but common sense: move.
tide: Between the shore and five metres of water there are 390 m, and no tide shifts that line appreciably. The current you will find towards the east will nearly always be wind-driven and not tidal. A surge pushed by Levante can raise the level more than the tide itself. Water pushing you towards the east, that is towards the open sea, is the signal to come out.
shelter: A shoal works the opposite way round from the coast: it shelters underwater and not on the surface, and nothing stops what passes over the top. The exposure measured on the coastline is 83°, that is full east: in Levante there is no shelter here, in Ponente the water flattens. The strip between the shore and the 5 m contour, about 390 m here, is the first to churn and the last to clear. Better to call it off from land than to discover the real sea two hundred metres out.
conditions: The survey puts ten metres about 1400 m from the shore and nothing deeper anywhere nearby. With 10 m reached about 1400 m out, the limit of the day is set by your breath and not by the distance. At Sirolo-Numana it pays to come out feeling you stopped early. The nearest river mouth is the first thing to look at after rain.
hazard: Over the cap of a shoal the water stands up and the ascent can put you in the middle of a breaker. On the shoreline at Sirolo-Numana the same national rules apply without discounts: breath-hold, daylight, marker in sight. With Levante building, the window shuts sooner than the forecast says. Better to come back empty-handed than not to come back on time.
access: Under the shore the bottom is what you see from above, 30 m from the coastline. In Levante the crossing out to the shoal is worth thinking about twice, because on the way back you will have it against you. With swell on the entry, change the spot instead of insisting. At Sirolo-Numana many accesses cross private property: if it is signed, look for another one.

Rocky banks off Numana; the Sirocco murks it up, the offshore Bora clears it.

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.

Look at the water
right now.

Check the cam BEFORE you leave. Foam, brown/green murk, or waves washing the entry rocks = No-go. At night/in fog the cam is useless — treat it as «unknown», NOT «green».

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 Sirolo-Numana

Where can I spearfish in Sirolo-Numana?

Sirolo-Numana has rock entry points such as Sassi Neri / Due Sorelle, Scoglio del Trave and Secca della Madonna. The only true rock of the central Adriatic: screes under the Conero cliff, the Trave reef with walls of 9–10 m and banks off Numana. Below you'll find each spot (access, shelter and hazards) and today's forecast.

When is the best season in Sirolo-Numana?

Mostly summer, and only on the Conero rock (Sirolo–Numana): the rest is sand and murk. The scirocco (SE) shuts visibility at once, the offshore bora (NE) often cleans it. In summer the 500 m bathing ban pushes you to dawn and dusk.

How cold is the water in Sirolo-Numana?

~12–26 °C depending on season. A 3–5 mm suit in summer, 5 mm in the shoulder months. On the Conero the water is relatively clear for the Adriatic; the scirocco clouds it fast.

Is Sirolo-Numana good for a beginner?

Demanding for visibility reasons: only the Conero holds up, the rest is sand and murk. You have to catch the good window (offshore bora that cleans). Summer 500 m bathing ban: dawn or dusk. Buoy always.

Do I need a licence in Sirolo-Numana?

No — in Sirolo-Numana 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.
