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
- ✓A SERNAPESCA recreational-fishing licence is required — it explicitly covers spearfishing (defined as capture by sport diving, apnea and spearguns). Online at pescarecreativa.sernapesca.cl. Free for 65+/under-12/disabled. Sale prohibited.
- ✓Unlike continental Argentina, scuba is not banned: the legal definition includes 'sport diving', so both apnea and scuba are legal. Respect RAV closed seasons (conger, corvina) and regional sizes.
- ⛔ 🚫 Loco (Concholepas) — permanent ban to 31 Dec 2028 (Arica→Aysén). Only by hand by the AMERB org; outsiders/recreational barred.
- ⛔ Elephant fish (Callorhinchus) and smoothhounds (Mustelus) — mandatory release. Don't shoot.
- ⛔ AMERB areas (hundreds of polygons): benthos (loco/lapa/erizo) — exclusive to fisher orgs, don't take; fish by speargun — grey zone, check locally.
- ⛔ Marine mammals, sea turtles, penguins — protected; do not touch.
Rules change. Before heading out, get the recreational licence (SERNAPESCA, pescarecreativa.sernapesca.cl) and respect the RAV closed seasons and regional sizes.
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 Antofagasta: spots, seasons and rules
Antofagasta is an exposed desert-rock session, not a protected cove plan. La Portada gives the famous arch and 0-15 m reefs; Caleta Coloso is quieter, with kelp and rock to 18 m south of town. Go early, confirm the ledge exit and keep the swim compact. SERNAPESCA, RAV closures, closed loco and AMERB limits apply.
TL;DR
- La Portada is the arch-and-reef option; Coloso is the quieter kelp cove south of town.
- Read southwest period and port foam before committing to the rock entries.
- Licence, RAV closures, closed loco and AMERB benthos rules travel with you.
Where can you spearfish in Antofagasta?
Use La Portada for the recognizable northern reef scene and Coloso for a quieter southern entry. Both are intermediate shore marks, not fallbacks for rough swell.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| La Portada | Arch and rock | 0-15 m | Intermediate | Shore entry | Arch and reefs north of the city, 0-15 m; iconic, some tourist traffic. Coords approx. Check the exit. |
| Caleta Coloso | Rocky cove | 0-18 m | Intermediate | Shore entry | Cove to the south, rock and kelp 0-18 m, shore; less pressure. Coords approx. Check the exit. |
How should Antofagasta be timed?
Small swell and light wind matter more than season. Humboldt upwelling can bring cold water even under clear skies, so read foam on the ledges before entering. Chile requires the SERNAPESCA recreational licence and includes sport diving, apnea and spearguns in the activity. Loco is closed to recreational take until 31 Dec 2028; elephant fish and smoothhounds are release-only. North of the city, the Reserva Marina La Rinconada is a no-take marine reserve, so confirm its limits and keep it off the hunting plan.
