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.

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.

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.

Law
- ✓Recreational fishing needs no PRODUCE permit, BUT spearfishing requires a DICAPI diver card/registration (Coast Guard), 18+. Spearing on scuba is banned.
- ✓RN Mar Tropical de Grau (Máncora/Tumbes/Piura) = protected area with restrictions; check the sectors before shooting.
- ⛔ 🚫 Seahorse, whale shark and manta ray — take banned. Don't shoot.
- ⛔ 🚫 RN Mar Tropical de Grau (D.S. 003-2024-MINAM), Paracas NR, San Fernando NR and RNSIIPG (guano islands/points) — no-take core zones: no hunting inside the rings.
Rules change. Before heading out, get the DICAPI diver card/registration (Coast Guard) — spearing on scuba is banned; check the sectors of RN Mar Tropical de Grau.
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 Callao: spots, seasons and rules
Callao works best when the spot choice follows the rule map. La Punta peninsula and, ten miles out, the Palomino and Cavinzas islands with their sea-lion colonies. Treat the names below as orientation only. Before entering with a speargun, get the DICAPI card; autonomous breathing gear is not allowed for spearing. Separate rock fish from closures in Peru: cabrilla and pintadilla may show, while chita pauses in December and lorna in April.
TL;DR
- Callao: urban breakwaters, sea-lion islands and naval control at San Lorenzo.
- Southwest swell pounds an exposed shore, so start at dawn; check the one webcam for color and foam before you commit.
- Sort the DICAPI card before you load; spearing on tanks is off the table here.
Practical spearfishing areas around Callao
These are practical orientation marks. Costa Verde's groynes and San Lorenzo's south wall only work on a small, low southwest set. If zoning is unclear, scout without take.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Costa Verde (Miraflores/Chorrillos) | mixed bottom | shallow to mid-depth | Intermediate | shore entry, only in small seas | Groynes and rock of Lima's urban seafront; hunting by the groynes. Keep the session short. |
| Isla San Lorenzo (pared sur) | wall and reef edge | 8-20m | Intermediate | shore entry, only in small seas | Peru's largest island off Callao; rock walls 8-20 m on the S/SW face. Keep the session short. |
How do season and rules combine in Callao?
Treat La Punta as a logistics dive: traffic, variable water and coordinated access. Conditions still beat the calendar: The worst sea is from SW; the coast is exposed, so dawn matters; upwelling can clear and cool the water at the same time; 1 webcam link helps check color and foam. Keep it breath-hold and treat unconfirmed protected water as closed. Costa Verde is the city option: groynes, urban rock and visibility that changes with swell and runoff. Palomino and Cavinzas are sea-lion islets inside the RNSIIPG framing, so wildlife disturbance is the red line even where a use zone exists. San Lorenzo adds 8-20 m rock walls on the south and southwest face, but access is boat-based and naval-controlled. If the bay is brown or the exit line is foamy, use the day to scout, not to load a gun.
FAQ
Do you need the DICAPI card in Callao?
Yes. Carry the DICAPI sport-diver card before you enter with a gun, and leave the tank on shore since scuba spearing is not permitted.
Is scuba spearing allowed in Peru?
No. Use freediving only, with the DICAPI card sorted first.
Which Peru closures matter near Callao?
Do not shoot chita in December or lorna in April.
How should you read visibility at Callao?
A southwest swell is the worst case on this exposed bay, so read it at dawn and lean on the single webcam for water color and foam before deciding.
What should be treated as off limits near Callao?
Avoid Islas Palomino / Cavinzas where it overlaps core, breeding-fauna or closed sectors; confirm with SERNANP in reserve water.
