Compiled by the spearo sea-state engine · How it works →

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.

01
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.
02
Wind & gusts
Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
03
Tide phase
Timing and range of the tide, calibrated per coast — big spring tides pull the verdict toward caution.
04
Water temperature
Sea-surface temperature — sharply cold water vetoes a green verdict.
05
Currents & outflow
Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
06
Rain runoff & air clarity
Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
07
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 — where night spearfishing is banned by law the window is forced red; where it is legal (Australia outside NSW, New Zealand, South Africa) it is capped at yellow, never green.

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: 3016 spots across 406 stretches of coast — mainland Portugal, Madeira and the Azores.

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.

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

    Spearfishing with a speargun is banned in Seychelles: the Fisheries Act 2014 (s.32(1)) prohibits using or carrying a speargun for fishing at any hour, day or night, and the Seychelles Fishing Authority confirms this covers recreational fishing. Fishing of any kind is illegal in the marine national parks (Ste Anne, Baie Ternay, Port Launay, Curieuse, Île Cocos). The spots here are snorkelling and freediving entries. Check sfa.sc before you go.

    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.

    FAQ — spearfishing in Beau Vallon

    Where can I spearfish in Beau Vallon?

    Beau Vallon has rock entry points such as Beau Vallon beach, Fisherman's Cove Reef (Bel Ombre) and Northolme Beach. Beau Vallon is the long beach and dive-centre hub of north-west Mahé, with the granite coves of Glacis to the north and Bel Ombre to the west. Below you'll find each spot (access, shelter and hazards) and today's forecast.

    When is the best season in Beau Vallon?

    SE trade winds (about May–October) make the south and east coasts (Anse Royale, Takamaka) choppy with seaweed while the north-west and west (Beau Vallon, Port Glaud, Anse à la Mouche) are calm; the NW monsoon (about November–March) reverses it.

    How cold is the water in Beau Vallon?

    About 26–27 °C in July–August and 29–30 °C in March–April.

    Is Beau Vallon good for a beginner?

    Mostly shallow reef lagoons and granite coves from the beach; the south tip (Police bays) gets open-ocean swell and some beaches are unsafe for swimming. Spearguns are banned in Seychelles.

    Do I need a licence in Beau Vallon?

    Beau Vallon: Spearfishing with a speargun is banned in Seychelles: the Fisheries Act 2014 (s.32(1)) prohibits using or carrying a speargun for fishing at any hour, day or night, and the Seychelles Fishing Authority confirms this covers recreational fishing.
