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.

On the rock

The forecast is the plan.
The call is on the rock.

The models set the window. Whether you go in is read only at the water: count the sets, watch the surge on the entry. If in doubt, you don't get in.

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.

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
  • Seahorses (Hippocampus) — protected (RPE).
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 Cartagena: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Cartagena is legality-first. The Cabo Tiñoso marine reserve is listed as closed to spearfishing, so Cabo Tiñoso and Cala Salitrona are boundary warnings, not open recommendations. El Portús is the clearest usable entry because it is outside the reserve boundary, semi-sheltered and easy. Isla de las Palomas sits under the Cabo Tiñoso reserve hard warning: treat it as a no-go unless a current boundary check proves otherwise. The legal split is Murcia plus Mediterranean sizes.

TL;DR

  • Do not treat Cabo Tiñoso reserve water as a spearfishing area.
  • Best practical start: El Portús, outside the reserve boundary and semi-sheltered.
  • Main weather risk: S-SE swell, with southeast worst for the city setup.

Best legal spearfishing spots near Cartagena

These shore-entry zones should only be used with settled sea, a visible buoy and confirmed local limits.

Conditions and season essentials

The bad sector runs from E-SE to SW, with southeast worst. El Portús has rocky ledges, sargo and octopus, and is listed outside the Cabo Tiñoso reserve. Isla de las Palomas toward Isla Plana is rocky ground with moderate SE exposure. Cabo Tiñoso has deep ledges and fish, but the marine reserve ban means it cannot be framed as open water. Cala Salitrona has tricky entry and south swell exposure. Murcia processes the spearfishing licence separately through CARM. The caladero is Mediterranean: seabass 25 cm, gilthead 20 cm, sargo 23 cm, grouper 45 cm, octopus 1 kg.
