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.

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».

- ✓Apnea only: spearing on a tank/scuba is banned (artificial breathing apparatus prohibited — IBAMA rule).

- ⛔ 🚫 Goliath grouper (Epinephelus itajara) — indefinite moratorium (CR). Not a legal target: do not take, release.
- ⛔ Hammerhead sharks (Sphyrna lewini/zygaena) and angel sharks (Squatina spp.) — red list, take banned. Don't shoot.
- ⛔ Sea turtles, whales/dolphins, seahorses — protected, taking/disturbing prohibited.
Rules change and vary by state. Before heading out, check on gov.br (recreational licence, MPA) and the state closed seasons/sizes; apnea only, goliath grouper is banned.
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 Guarujá: spots, seasons and rules
Spearfishing in Guarujá is about choosing the seaward granite headlands and avoiding dirty urban water near the Santos port channel. Astúrias, Pitangueiras, Pernambuco and Perequê are the useful names, with local visibility stated at 4 to 12 m. If south or southwest sea is running, exits over rock become a weak plan. MERO TOTAL MORATORIUM applies here: goliath grouper is not legal. You also need the gov.br recreational licence, fee-exempt only for accompanied under-18s and for men 65+/women 60+, and legal spearfishing is apnea only.
TL;DR
- Guarujá is an outer-headland plan: Astúrias and Pernambuco make more sense than water near the Santos port channel.
- Local visibility is modest, 4 to 12 m, and south to southwest sea is the poor setup.
- Laje de Santos Marine State Park is no-take, so it is not a hunting destination.
Best spearfishing spots in Guarujá
Keep the plan on the outer coast and away from the port channel. Laje de Santos is a no-take marine park about 40 km offshore, so it belongs on the exclusion list, not the target list.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Praia das Astúrias headland | Urban granite headland | Shallow to moderate, no tighter local number | Intermediate | Shore entry with exit chosen before entering | Use it only when the water looks clean on the outer point. Swimmers, small craft and urban runoff all reduce the margin. |
| Praia de Pernambuco headland | Outer seaward point | Shallow to moderate | Intermediate | Shore entry in small-sea windows | Better aligned with cleaner water than the port side. South or southwest swell should cancel the rock exit. |
What conditions matter in Guarujá?
The local visibility band is only 4 to 12 m, so water color matters more than optimism. Look for small sea on the outer headlands and use the Enseada or Pitangueiras camera only as a first filter. National rules still control the day: gov.br licence required, apnea only, no scuba spearing, and goliath grouper under total moratorium. If any protected-area limit is uncertain, treat it as closed.
FAQ
Do you need a licence in Guarujá?
Yes. Use the gov.br recreational fishing licence service. Its fee is waived only for accompanied under-18s and for men 65+/women 60+.
What visibility should you expect?
The stated local range is 4 to 12 m, with dirty water more likely near the Santos port influence.
Can you spearfish at Laje de Santos?
No. It is a no-take marine state park and should not be treated as a hunting spot.
Can you spear goliath grouper?
No. Goliath grouper, called mero in Brazil, is under total moratorium.
Is Guarujá a beginner solo dive?
Not as a first outing. Rock exits, boat traffic and variable water all demand conservative judgment.
