Today — right on the edge — wave, wind and visibility.

The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.
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.
Safety gates
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.
Where to get in, where to hunt
Wind, wave and the swell windows — when to go and the best hours.

Leave your email — and the moment a window opens at Blankenberge, we'll send the go / no-go verdict. Email is all we need.

Visibility and what drives it — post-storm clearing, river plume, temperature and the thermocline.
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.
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.

Spearfishing is not among the recreational sea-fishing methods recognised in Belgium (Flemish fisheries agency guide 2026), and diving federations forbid it — treat it as not permitted and check locally. No fishing at all in the Baai van Heist reserve; no fishing from a boat 22:00–05:00. Forecasts are for freediving and snorkelling.
Blankenberge has rock entry points such as Blankenberge pier, Wenduine and Zeebrugge west dam. Resort town with a long pier between Wenduine and Zeebrugge. Below you'll find each spot (access, shelter and hazards) and today's forecast.
