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 — forced red; the window is closed after dark.

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: 1152 spots across 189 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.

Law
  • Fan mussel (Pinna nobilis) — strictly protected, taking/disturbing prohibited (mass die-off from a pathogen).
  • Date mussel (Lithophaga lithophaga) — harvesting strictly banned (destroys the reef).
  • Seahorses (Hippocampus), loggerhead turtle (Caretta caretta) and monk seal (Monachus monachus) — protected, taking/disturbing prohibited.
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.

Spearfishing in Dubrovnik: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Dubrovnik spearfishing is legality-first because Lokrum is listed as a protected special reserve. Its reefs are described with white sea bream, conger eel and gilthead bream, but the local ban warning controls the plan. Grebeni off Lapad is an offshore shoal listed for dentex and amberjack. Uvala Slano, north of the city, is a sheltered rocky bay listed for gilthead bream and sea bass. The bad sea sector is 120-240 degrees, with south as the strongest warning direction.

TL;DR

  • Dubrovnik has three listed areas: Lokrum reefs, the Grebeni shoal off Lapad and sheltered rocky Slano north of town.
  • Lokrum is marked as a protected special reserve; respect local fishing bans and do not treat it as an open top spot.
  • Use the Croatian sport licence, freedive only, daylight only, marker buoy required; ordinary recreational licences do not cover spearguns.

Which Dubrovnik spearfishing areas are listed?

The table separates legal caution from fishing character. Lokrum is not framed as a free hunting recommendation because the protected-reserve warning is explicit.

What should you check first in Dubrovnik?

Check legal status before conditions around Lokrum. The spot note says Lokrum is a protected special reserve and local bans must be respected. For sea state, Dubrovnik has a 210 degree aspect, with 120-240 degrees as the bad sector and south as the main warning direction. The Adriatic tide is small, so wind, swell and visibility decide more than tide tables. Croatian law requires the sport sea-fishing licence for spearguns, not the recreational licence. It is breath-hold only, daylight only, minimum age 16, with a mandatory marker buoy and no more than two spearguns per diver.

FAQ

Can I spearfish freely at Lokrum?

No. Lokrum is listed as a protected special reserve, and local bans must be respected.

What is Grebeni off Lapad?

It is listed as an offshore shoal for dentex and amberjack.

Is Slano exposed like the reefs?

No. It is described as a sheltered rocky bay north of the city.

Does Croatia allow scuba spearfishing?

No. Spearfishing is breath-hold only.

What licence do tourists need?

The sport sea-fishing licence; the ordinary recreational licence is not enough for spearguns.
