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 — 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.
