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.
Open the seafloor mapBradstreet Fishing Pier: lake shore, 1.4 km from Rocky River. Access type in the OpenStreetMap data: pier. The shore here faces Lake Erie. The pin is about 60 m from the lake shoreline. Check the state's current spearing rules before you dive.

Rocky River is a Ohio town on Lake Erie. Ohio lets forage fish — drum, carp, suckers, gar, bowfin and the rest — be taken by any method outside a listed set that does not include spears, while game fish are treated as closed. We have two public access points here, Bradstreet Fishing Pier among them, from OpenStreetMap, and none of them is a surveyed dive site: treat them as entries, not marks. The shore faces north, and wind from 290–60° closes it.
Forage fish yes, game fish no at Rocky River: Ohio lets its forage-fish class be taken by any method outside a listed set, and spears are not in that set. Ohio never writes the word spearfishing. It defines a forage-fish class and allows it to be taken by any method except a listed set — explosives, poisons, firearms, electricity, chemicals, nets other than cast nets, seines, traps and snagging below posted dams — and spears, gigs and bows are not in that list. Nothing opens a game fish to the spear, and OAC 1501:31-13, which would settle it, could not be opened in this research, so the safe reading is that walleye, yellow perch, smallmouth bass and the salmonids are closed. An Ohio fishing licence is required. Our no-take layer shows no mapped no-take or restricted zone within 15 km of Rocky River. The rule is the same at every Rocky River entry — Bradstreet Fishing Pier and Huntington Beach. Cleveland, 13 km away, sits under the same Ohio rule.
The forage-fish class: freshwater drum (sheepshead), common carp, grass carp outside waters stocked for vegetation control, bighead, silver and black carp, quillback, suckers, bowfin, gar, buffalo, gizzard shad and goldfish. Identify a gar before you shoot — alligator, shortnose and spotted gar are Ohio state endangered, as are lake sturgeon, shovelnose sturgeon, cisco, longnose sucker and goldeye, and their possession is prohibited in all Ohio waters. It applies the same way at both Rocky River entries — Bradstreet Fishing Pier and Huntington Beach.
US spearfishing law is state-by-state. License, spearable species, powerhead rules and distances vary; federal sanctuaries (Gray's Reef, the Keys, Flower Garden Banks) ban spearfishing. Always confirm with the state agency and local ordinances.
Two public access points carry the Rocky River forecast: Bradstreet Fishing Pier (pier) and Huntington Beach (beach). They come from OpenStreetMap — the official site name, the coordinate and the access type, nothing more — so none of them is a surveyed dive site and no depth is recorded for any. The nearest town we already covered is Cleveland, about 13 km away. Treat each one as a way into the water and read the bottom yourself.
This is the same central-basin water as Cleveland: deeper and cleaner than the western basin, but visibility is poor after any blow. Ice cover on Lake Erie often reaches 90-100 % in February; the season runs May to October and the water reaches 22-24 °C in August. There is no tide — the Great Lakes astronomical range is a few centimetres. At Rocky River the shore faces north (350°): wind and swell from 290–60° close it, worst from about 10°, so outside that arc the forecast is worth a look.
No. Treat game fish as closed: Ohio publishes nothing that opens them to the spear, and OAC 1501:31-13 could not be read. Off Bradstreet Fishing Pier, the open list is forage fish.
Gar is in Ohio's forage-fish class, but identify it first: alligator, shortnose and spotted gar are state endangered and may not be possessed in any Ohio water. Off Bradstreet Fishing Pier as anywhere on the Ohio shore, an unidentified gar is not a shot.
From the mapped public entries: Bradstreet Fishing Pier (pier) and Huntington Beach (beach). None of them is a surveyed dive site, and no depths are recorded.
Wind and swell from 290–60°, worst from about 10°: the shore by Rocky River faces north (350°). Outside that arc, Bradstreet Fishing Pier and the other entries are worth a look.
May to October, water 22-24 °C in August. From January to March the lake and its harbours ice up, so Bradstreet Fishing Pier and Huntington Beach are a summer-and-autumn plan.
