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

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.
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 Fehmarn, 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.
Open the seafloor mapBeach entry after a short walk from a small wood by the shore on Fehmarn's east coast. Sand and seagrass give way to large boulders covered in algae and mussels, reaching about 15 m. Summer boat traffic — tow a buoy; look out for gillnets. Spearfishing not permitted here — check local rules.
Google MapsShore entry below Staberhuk lighthouse on Fehmarn's south-east tip, swimming out to the east. Gravel fields and large stable boulders form a stony reef in the shallows down to about 10 m. Watch for current off the point and avoid strong easterly winds. Spearfishing not permitted here — check local rules.
Google MapsBeach entry on Fehmarn's west coast from parking at the dike, about 30 m from the water. Sand with rubble and weed patches from about 3 m around a pile 50 m out, to around 6 m. Moderate current possible — not for strong onshore wind. Spearfishing not permitted here — check local rules.
Google MapsBoat dive off Fehmarn's east coast near Katharinenhof to a broken-up wreck whose collapsed south side forms a short tunnel. The east side drops to about 16 m. Do not enter collapsed sections without proper wreck training. Spearfishing not permitted here — check local rules.
Google MapsVery shallow site entered from the beach or the small harbour mole at the Wulfener Hals campsite. Sand, small marl banks and wide seagrass meadows at 2.5–3 m. Boat traffic near the harbour — use a buoy. 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.
Fehmarn has rock entry points such as Staberhuk, Katharinenhof and Wulfener Hals. Germany's third-largest island, on the Fehmarn Belt. 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.
Boulder flats, eelgrass and wrecks; Kiel Fjord and Lübeck Bay carry heavy shipping. Spearfishing is banned (KüFVO SH § 9) — freediving and snorkelling only.
