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.

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.

Google MapsSOLO 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.
Cameras, map and reference — to hand as you come up.
Spearfishing is banned in German coastal waters: Schleswig-Holstein (Küstenfischereiverordnung 2018, § 9(1)), Mecklenburg-Vorpommern (KüFVO M-V, § 16(1)) and Lower Saxony (Fisheries Act, § 44(1) no. 5) prohibit spears and harpoons for any fishing, at any hour. The Helgoland rock-base reserve and the Jasmund National Park strip are closed to all fishing. Forecasts here are for freediving and snorkelling; leave the speargun at home.
Cuxhaven has rock entry points such as Kugelbake, Duhnen Buhnen and Sahlenburg. Port town at the mouth of the Elbe. Below you'll find each spot (access, shelter and hazards) and today's forecast.
June–September; the shallow Wadden Sea turns murky quickly in wind — best in calms at neap tides.
4–5 °C in February, 17–19 °C in August — a drysuit or 7 mm in winter, 5–7 mm in summer.
Wadden Sea sandbanks, groynes and channels with strong tidal currents; Cuxhaven sits on the Elbe mouth with heavy shipping. Spearfishing is banned (Nds. FischG § 44).
