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.
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.

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 (mero, Epinephelus itajara): total moratorium since 2002, renewed (in force 2026+). Never a legal target — capture/transport/sale is an environmental offence.
- ✓Closed seasons (vary by state): true grouper & badejo in the N/NE 1 Aug–30 Sep; bluefish in the S/SE ~1 Dec–31 Mar; robalo reopens after 31 Jul (state-dependent). Mind minimum sizes.
- ⛔ 🚫 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 Rio de Janeiro: spots, seasons and rules
Spearfishing in Rio de Janeiro is not an all-beach plan. The useful side is the ocean coast, especially Barra, Recreio and the Tijucas Islands offshore, where rocky water can be clearer than expected for a major city. The stated outer-island range is 5 to 15 m visibility and 18 to 25 °C water. Guanabara Bay is out because of pollution and practical restrictions. MERO TOTAL MORATORIUM means goliath grouper is not a target. Use the gov.br recreational licence, whose fee is waived only for accompanied under-18s and seniors (men 65+, women 60+), and dive apnea-only.
TL;DR
- Rio spearfishing belongs on the ocean side: Barra, Recreio and the Tijucas Islands, not Guanabara Bay.
- Outer-island visibility is stated at 5 to 15 m, with 18 to 25 °C water.
- Frequent south swell and heavy boat traffic make a bright float and short plan essential.
Best spearfishing reference in Rio de Janeiro
The listed option is offshore. Use Barra and Recreio as the ocean-side context, but do not turn crowded urban beach water into a hunting plan.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Tijucas Islands off Barra | Outer rocky islands | No fixed local depth; use the 5 to 15 m visibility band as the condition cue | Intermediate to advanced | Boat, float and surface support | Potentially clearer than the city shore, but current, pickup, boats and south swell must all be simple. |
What conditions matter in Rio?
Small ocean-side sea is the key. South ressaca is common and should stop the plan when it breaks over rocks or turns the water milky. The Copacabana camera can show general sea color and size, but it does not clear an offshore dive. Nationally, the licence is required, spearing on scuba is banned, and goliath grouper is fully protected by moratorium. Treat any uncertain boundary or polluted bay water as a no-go.
FAQ
Do you need a licence in Rio?
Yes. Use the gov.br recreational fishing licence service. The fee is waived for accompanied under-18s and for seniors (men 65+, women 60+).
Can you hunt in Guanabara Bay?
No. The local plan keeps spearfishing on the ocean side, not the polluted bay shore.
What visibility is stated offshore?
The outer-island range is 5 to 15 m.
Are the Tijucas Islands beginner-friendly?
No. Treat them as boat dives with surface support.
Can you spear goliath grouper?
No. Goliath grouper, or mero, is under total moratorium in Brazil.
