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.

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.
Entry points
Where to get in
off the rocks.
Scouted entries, coloured by today. The colour is the sea state at the spot, not a guarantee: the wash and a slippery entry you judge on site.
Open the seafloor map
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
- ✓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 Algarrobo: spots, seasons and rules
Algarrobo is a sheltered bay route kept away from the penguin islet. Bahia Algarrobo is listed as rock and sand in 0-12 m with partial shelter. End the plan if wind or drift points toward sensitive wildlife. Wildlife distance, licence and closed resources are all part of the route. North-sector weather is the weak point.
TL;DR
- The route stays in Bahia Algarrobo and away from the penguin islet.
- No camera means north wind, summer traffic and exits are checked from shore.
- Wildlife distance is as practical as the SERNAPESCA licence.
Where can you spearfish in Algarrobo?
Bahia Algarrobo is the practical mark: sheltered shallow rock and sand, with a clear need to stay away from the penguin islet.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Bahía Algarrobo | Rock and sand bay | 0-12 m | Accessible to intermediate | Shore entry | Sheltered north bay, rock+sand 0-12 m, shore; away from the penguin islet. Coords approx. Check the exit. |
What boundary matters in Algarrobo?
The bay can help with shelter, but it does not justify moving toward the islet. Keep the route compact and visible from shore. Chile requires the SERNAPESCA licence and recognises spearfishing through sport diving, apnea and spearguns. Loco is closed to recreational take until 31 Dec 2028, AMERB benthos is not for recreational harvest, and penguins are protected wildlife. Do not follow fish toward birds, boats or unclear rocks near the islet. Bahia Algarrobo is a north-opening protected bay with good SW shelter and easy shore entries, so the useful route stays on the 0-12 m rock-and-sand band. Keep the swim short enough that the same beach exit remains visible. The penguin islet is a feeding zone and stays outside the hunt. There are no listed webcams or buoy for Algarrobo, which makes the shoreline check part of the plan. Read the north-sector wind or swell before committing, then keep the exit close enough to reverse if the bay loses shelter. If the bad sector starts to show, use shore conditions instead of pushing farther out. The local bottom is cold, clear rock and sand with vieja, rollizo and sargo. Vieja and pejeperro are one-fish-per-day species, while sargo and rollizo sit under the five-fish item limit and the overall jornada cap. A 5-7 mm suit matches the Humboldt water called out for the bay. The listed entry remains from shore, not by boat.
