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.
The day is picked above, in the hero. Here are that day's windows, the hour-by-hour map and the trends. Tap a window to break down the conditions.
Leave your email — and the moment a window opens at Sassnitz, 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.
See all spotsRelief and bottom type, tides, and the depths of each spot.
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.
Open the seafloor mapEntry from Göhren north beach; the giant granite boulder lies about 350 m out and is reached underwater over alternating boulder fields and sand in 15–20 minutes on a compass bearing. Smaller boulders around it stay permanently submerged. Use a surface marker buoy — boats pass along this shore. Spearfishing not permitted here — check local rules.

Google MapsWreck of the fishing cutter SAS 33 Sturmvogel, sunk in 1984 after a collision with a ferry; reached by boat from Sassnitz. The 17 m hull lies on sand, tilted to port, from about 12 m down to 16 m. Old fishing nets hang on the stern — carry a knife and a surface marker. Spearfishing not permitted here — check local rules.
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.
Sassnitz has rock entry points such as Hafenmole Sassnitz, Wrack Sturmvogel and Wissower Klinken. Ferry port at the foot of Rügen's chalk cliffs. Below you'll find each spot (access, shelter and hazards) and today's forecast.
May–September; the water warms by July and summer algal blooms are possible; sea level follows the wind (setup), not the tide.
2–4 °C in February, 17–20 °C in August — a drysuit or 7 mm in winter, 5–7 mm in summer.
Chalk and moraine shores, boulders and wrecks; visibility usually 2–6 m. Spearfishing is banned (KüFVO M-V § 16) — freediving and snorkelling only; the Jasmund National Park strip is closed to all fishing.
