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

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 mapErie Shores Park is a lake shore entry about 5.1 km from Avon Lake. Water body: Lake Erie. Coordinates of the entry: 41.500 N, 82.075 W. Fresh water floats you less, so trim your weights. Check the state's current spearing rules before you dive.
Google MapsMiller Road Park: lake shore, 3.8 km from Avon Lake. OpenStreetMap lists the site as a waterfront park. The shore here faces Lake Erie. Coordinates of the entry: 41.504 N, 82.061 W. Which fish may be speared, and when, is set by the state; read the 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.
Avon Lake 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, Erie Shores Park 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 298–68° closes it.
Forage fish yes, game fish no at Avon Lake: 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 Avon Lake. The rule is the same at every Avon Lake entry — Erie Shores Park and Miller Road Park. Rocky River, 14 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 Avon Lake entries — Erie Shores Park and Miller Road Park.
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 Avon Lake forecast: Erie Shores Park (beach) and Miller Road Park (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 Rocky River, about 14 km away. Treat each one as a way into the water and read the bottom yourself.
Lake Erie freezes hard — ice cover often reaches 90-100 % in February — and then warms first of the Great Lakes, to 22-24 °C in August, so the season here is May to October. Along this central-basin shore near Cleveland the water is cleaner than in the west, yet any blow leaves it murky for a while. No tide to plan around: the astronomical range is a few centimetres. At Avon Lake the shore faces north (358°): wind and swell from 298–68° close it, worst from about 18°, 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 Erie Shores Park, 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 Erie Shores Park as anywhere on the Ohio shore, an unidentified gar is not a shot.
From the mapped public entries: Erie Shores Park (beach) and Miller Road Park (beach). None of them is a surveyed dive site, and no depths are recorded.
Wind and swell from 298–68°, worst from about 18°: the shore by Avon Lake faces north (358°). Outside that arc, Erie Shores Park and the other entries are worth a look.
May to October, warmest in August at 22-24 °C. From January to March the lake and its harbours ice up, so Erie Shores Park and Miller Road Park are a summer-and-autumn plan.
