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.

How we score the water

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.

01
Swell & wave memory
Height, period and direction of the swell, plus the wake of recent storms — an old storm still stirs the water, and the engine remembers.
02
Wind & gusts
Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
03
Tides — none here
The Great Lakes are fresh water: there is no tide, so this factor never moves the verdict. The level is pushed around by wind setup and seiche instead.
04
Water temperature
Lake surface temperature from NOAA GLERL's GLSEA daily composite, not an ocean model — sharply cold water vetoes a green verdict.
05
Currents & outflow
Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
06
Rain runoff & air clarity
Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
07
Coast shape & exposure
How the coast faces the swell — a sheltered cove keeps the water clean; an exposed, head-on point takes a penalty.

Safety gates

  • Thunderstorm forecast — an instant red, no exceptions.
  • An official warning (MeteoAlarm / IPMA) — yellow, or red for the higher ranks.
  • Missing input data — a would-be green is capped to yellow rather than overstated.
  • Strong disagreement between forecast models — a green day is pulled back to yellow.
  • Night hours — where night spearfishing is banned by law the window is forced red; where it is legal (Australia outside NSW, New Zealand, South Africa) it is capped at yellow, never green.

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.

What it is

A marine instrument,
go / no-go for solo hunting.

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.

SOLO 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.

What's in season,
what the law says.

In season now
  • no targets this month
Regulated — check your state
  • Common carp📋 season by state
    The one species spearable almost everywhere a spear is legal at all: Michigan and Wisconsin year-round, Ohio as forage fish, Pennsylvania under 58 Pa. Code 63.8 with a non-mechanical spear. New York gives you a bow instead, carp only, 15 May – 30 September. Illinois and Indiana list it but neither names Lake Michigan as a spear water.
  • White sucker📋 season by state
    Rough fish in Michigan, Wisconsin, Ohio and Pennsylvania, so it is lawful quarry wherever those states let a spear in the water. Identify the fish first: Ohio and New York protect the longnose sucker, and Wisconsin excludes any listed threatened or endangered sucker from its rough-fish class.
  • Freshwater drum (sheepshead)📋 season by state
    Ohio's forage-fish class names the sheepshead by name, so it is a real Lake Erie spear target. Michigan and Wisconsin carry it year-round; Pennsylvania's 58 Pa. Code 63.8 list does not include it, so it may not be speared there.
  • Channel catfish📋 season by state
    Michigan's year-round list and Pennsylvania's 58 Pa. Code 63.8 list both name catfish; Illinois names channel catfish expressly. Minnesota allows catfish by spear only from a dark house through the ice, never underwater.
  • Bowfin📋 season by state
    Rough fish in Michigan, Wisconsin and Ohio, with no bag limit at all in Minnesota's inland waters. Illinois and Indiana both list it, but neither names Lake Michigan among its spear waters.
  • Longnose gar📋 season by state
    Rough fish across the western lakes; Minnesota caps the take at 10 in its inland waters. In Ohio the alligator, shortnose and spotted gar are state endangered even though 'gar' is a forage fish — identify the gar before you shoot.
  • Sea lamprey (invasive)📋 season by state
    Wisconsin's rough-fish definition includes lamprey, so it may be speared on the outlying waters; Illinois lists it too, with no live possession. In Michigan it is not on the spear list at all, and fishing anywhere in a fish ladder or within 100 feet of a lamprey control weir is prohibited.
Not a target — don't shoot
  • Lake trout🚫 no-take
    Underwater spear only in the Michigan waters the 2026 regulations name: Lake Michigan from the MI/IN border north to the 45th parallel, a 2-mile strip in Green Bay to the Ford River mouth, a 5-mile strip from Point Detour to the Brevort River, Lake Huron from the Thunder Bay River pier to Fort Gratiot Light, Lake Erie to the Celeron Island line and Lake Superior to the St. Marys River. Grand Traverse Bay, Stannard Rock, Big Reef and a 4.5-mile ring round Isle Royale are excluded. 15 in minimum; season and limit run by management unit. Nowhere else in the eight states.
  • Lake whitefish🚫 no-take
    On Michigan's year-round spear list in all state waters except designated trout lakes and streams and the Michigan/Wisconsin boundary waters. Wisconsin treats it as a game fish and bans the spear on it in the outlying (Great Lakes) waters.
  • Cisco (lake herring)🚫 no-take
    On Michigan's year-round spear list and a genuine Great Lakes target there. In Ohio the cisco (lake herring) is a state endangered species — possession is prohibited in every Ohio water.
  • Walleye🚫 no-take
    Underwater spear only in the named 2026 Michigan waters (Lake Michigan to the 45th parallel, the Green Bay and north-shore strips, Huron, Erie, Superior; Grand Traverse Bay, Stannard Rock, Big Reef and the 4.5-mile ring round Isle Royale excluded): 15 in minimum, 5 a day. Lake St. Clair, the St. Clair River and the Detroit River are not in the row at all. Every other state on the lakes bans the spear on walleye outright.
  • Northern pike🚫 no-take
    Michigan: underwater spear in the named 2026 waters (Lake Michigan to the 45th parallel, Huron from the Thunder Bay River pier to Fort Gratiot Light, Erie, Superior; Grand Traverse Bay, Stannard Rock, Big Reef and the 4.5-mile ring round Isle Royale excluded), possession season 1 July – 15 March, 24 in minimum, 2 a day; plus a separate hand-spear ice season 1 December – 15 March. Wisconsin allows pike by spear only through the ice on Lake Superior — never underwater.
  • Muskellunge (musky)
Law
  • •Michigan is the only jurisdiction in the region with a purpose-built underwater-spearfishing regime: a FREE annual underwater spearfishing licence, mandatory and separate from the fishing licence, resident and non-resident alike. From the 2026 season the monthly online effort-and-harvest report is ABOLISHED — the DNR dropped the reporting and kept the licence. Fishing licence: resident $26/yr, non-resident $76/yr, $10 daily.
  • •Michigan, gear and conduct: breath-hold ONLY — scuba and rebreathers are prohibited while underwater spearfishing; daylight only (banned from 30 min after sunset to 30 min before sunrise); a speargun may be fired only while submerged and must be tethered to a line no longer than 20 ft (6 m); bands off the spear and the safety on when moving between areas and entering or leaving the water; never within 150 ft (46 m) of a designated swimming area, boat dock, boat access site or power intake. New for 2026: the use of bait, attractants or decoys while underwater spearfishing is prohibited, and the diver must be fully submerged when taking a fish.
  • •Wisconsin is the only state here that names SCUBA as lawful for underwater spearfishing («by skin and scuba diving») — but on the outlying waters (the Great Lakes) no GAME FISH may be speared: panfish, white/yellow/rock bass, bullheads and rough fish only, sunrise to sunset. Licence: resident $20/yr, non-resident $55/yr.
  • •New York and Minnesota: there is NO Great Lakes spearfishing. New York — ECL 11-1301(1)(a)/(c): spear and speargun are lawful only in the marine and coastal district. Minnesota — the underwater harpoon gun is authorised for INLAND waters only, for common carp and native rough fish, sunrise to sunset (Minn. Stat. 97C.371, Minn. R. 6262.0600); Lake Superior is closed.
  • •Pennsylvania: 58 Pa. Code 63.5 makes every method unlawful unless specifically authorised; 63.8 authorises spears and gigs for snakehead, carp, suckers and catfish, and 63.8(c) forbids a mechanically propelled spear — so a speargun is unlawful everywhere in PA. Ohio: its «forage fish» class (thirteen rough species) may be taken by any method except a short list that does not include spears, so spearing them is lawful — but Ohio publishes no rule permitting a spear on any game fish. Indiana and Illinois: their spear paragraphs do NOT name Lake Michigan — status unconfirmed.
  • •Fresh water is not the sea: there is no tide here (the level moves with wind setup and seiche, and NOAA CO-OPS publishes no tide predictions for Great Lakes stations at all), and in winter the ice and 1–4 °C water are the season's real hazard. This page reads the water temperature from NOAA GLERL (GLSEA ACSPO) rather than from the marine model, which answers nothing on these lakes.
Safety protocol
  • Sets: watch the wave trains ≥15 min before entering; Hmax ≈ 2×Hs. Lake waves are short-period (NWS: roughly 3–4 s on average in summer) and steep, and they grow with wind strength, fetch and how long the wind has blown — a lull promises nothing here; enter right after a full set passes and re-check at minute 30.
  • Exit FIRST: find your exit AND a backup before entering. On a breakwall or a boulder revetment a modest rise in wave height can make the exit impossible — plan for not being able to climb out, and leave while the exit is still easy.
  • Structural current: near piers, breakwalls and river mouths currents can form and strengthen when waves and surf pick up (NWS describes structural and rip currents at exactly these features) — stay well clear of piers and breakwalls, especially the side the waves are hitting, and of river mouths and channel outlets: that is where the current runs strongest (NWS). If one catches you anyway, never swim against it.
  • Cold: wetsuit per the lake-temperature chip (GLERL surface — below the thermocline it is colder still); cold water shortens the safe time in the water — plan short sessions, wear a thicker suit than you think you need, and get out at the first steady shiver. Where the limit sits depends on your exposure protection, your workload and you (NOAA).
  • Solo discipline: buoy up; tell someone the spot and exit time; conservative breath-hold (never push it in cold/murky/surfy water); visibility <3 m — don't enter.
  • Afternoon wind: on the Great Lakes, on sunny days with a light gradient wind, a lake breeze often sets in around midday and the chop can build quickly — plan to be out of the water by midday; when the chop builds, get out.
  • UV 11:00–15:00 (UVI ≥6): sunscreen and cover up on the surface interval.
  • Solo is a fundamental risk (hypoxic blackout with no buddy). Any doubt = No-go.

Spearfishing in Highland Park: spots, seasons and rules

Updated 2026-10-07 · By Oleksandr, spearfisher

Highland Park is a Illinois town on Lake Michigan. Illinois names the underwater spear gun as lawful gear for rough and non-native fish only, and the list of waters open to it does not include Lake Michigan — so the lake is restricted and unresolved. We have four public access points here, Millard Beach among them, from OpenStreetMap, and none of them is a surveyed dive site: treat them as entries, not marks. The shore faces north-east, and wind from 3–133° closes it.

TL;DR

  • Restricted and unresolved at Highland Park: Illinois names the underwater spear gun as lawful gear, but 810(d) does not list Lake Michigan among the waters open to it.
  • Illinois bars taking aquatic life along, upon, across or from any public right-of-way, and Millard Beach is public lakefront. Treat it as a swim and dive entry, not a place to hunt from.
  • Four public access points are mapped for Highland Park — Millard Beach, Park Avenue Boating/Fishing Beach, Rosewood Beach and Moraine Park; none is a surveyed dive site and no depths are recorded.
  • Highland Park's shore faces north-east (63°); wind from 3–133° closes it, worst around 83°. Season: June to October, best visibility August to October.

Is spearfishing allowed in Highland Park?

Restricted and unresolved at Highland Park: Illinois names the underwater spear gun as lawful gear, but 810(d) does not list Lake Michigan among the waters open to it. 17 Ill. Adm. Code 810(a) names the underwater spear gun as a lawful method with a sport fishing licence, but only for the species in 810(b). Subsection (d) enumerates the waters open to spear methods, and Lake Michigan is not among them; whether the site-specific Section 810.45 reaches the lake could not be resolved. Illinois also makes it unlawful to take or attempt to take aquatic life along, upon, across or from any public right-of-way. Treat the water as restricted and unresolved, and confirm with IDNR before you carry a gun. Our no-take layer shows no mapped no-take or restricted zone within 15 km of Highland Park. The rule is the same at every Highland Park entry — Millard Beach, Park Avenue Boating/Fishing Beach, Rosewood Beach and Moraine Park. Winnetka, 10 km away, sits under the same Illinois rule.

Which fish can you take at Highland Park?

Only the 810(b) list, if the water were open: gars, buffalo, bullheads, redhorse, catfish, blue sucker, bowfin, drum, gizzard shad, carpsuckers and suckers, plus the non-natives — bighead, black, common, grass and silver carp, goldfish, northern snakehead, oriental weatherfish, pacu, round goby, sea lamprey, tilapia and white catfish. No trout, salmon, yellow perch, walleye, pike, bass or whitefish. It applies the same way at all four Highland Park entries — Millard Beach, Park Avenue Boating/Fishing Beach, Rosewood Beach and Moraine Park.

    All 367 spots → · spearo.app — All countries

    🚫 no-take
    Michigan only, and only by hand spear through the ice 1 December – 15 March: muskellunge is not on the 2026 underwater-spear list at all. On Lake Erie, Lake St. Clair, the Detroit River and the St. Clair River it is hook and line only, by name.
  • Smallmouth bass🚫 no-take
    No Great Lakes state authorises a spear on black bass. Michigan, Wisconsin, Minnesota, Illinois, Indiana and Pennsylvania all publish enumerating lists and bass is on none of them; New York bans every spear in fresh water.
  • Largemouth bass🚫 no-take
    Same rule as the smallmouth: no Great Lakes state puts black bass on a spear list, and New York bans the spear in fresh water altogether.
  • Yellow perch🚫 no-take
    Wisconsin is the one place a diver can shoot it: panfish carve-out on the outlying waters, skin or scuba, sunrise to sunset, while the rough-fish spearing season is open. Michigan allows it only by hand spear through the ice on Lake St. Clair, 1 December – 15 March.
  • Burbot🚫 no-take
    Pennsylvania's burbot fishery is the one real underwater lane in the eastern lakes: scuba divers only, non-mechanical spear or gig, at least 60 ft, 1 June – 30 September, 5 a day, no minimum size, fishing licence plus Lake Erie permit. Michigan and Wisconsin carry burbot on their year-round rough-fish lists.
  • Longnose sucker🚫 no-take
    State endangered in Ohio and threatened in New York — fishing for it and possessing it are illegal there, catch and release included in New York. Elsewhere it falls under the general 'suckers' allowance, which is exactly why a diver must tell the sucker species apart before shooting.
  • Round goby (invasive)🚫 no-take
    Illinois is the only one of the eight states that names the round goby as a lawful spear target, and it never names Lake Michigan among its spear waters; no live possession either. Michigan and Minnesota only ban possessing or transporting it alive — a ban is not a permission to shoot it. And the fish is too small to be a real target.
  • Lake sturgeon (protected)🚫 no-take
    Protected in all eight states — endangered or threatened, no open season, possession prohibited. Michigan's only spear season is an inland, pre-registered winter season on Black Lake; in New York even catch and release is illegal. Never a target on any Great Lake.
  • Chinook (king) salmon🚫 no-take
    No Great Lakes state authorises a spear on salmon. Michigan's table lists only lake trout among the salmonids; the salmon stamps sold in Illinois, Wisconsin, Indiana and Pennsylvania are for rod and line, not for a spear.
  • Coho (silver) salmon🚫 no-take
    Same answer as the chinook: not on a single spear list in the eight states, and New York bans the spear in fresh water outright.
  • Steelhead (migratory rainbow trout)🚫 no-take
    Nowhere spearable. On top of that, Pennsylvania bans spearfishing in and along every Lake Erie tributary stream, and Indiana bans even possessing a spear on Trail Creek, the East and West Branch Little Calumet, Salt Creek, Burns Ditch, Deep River below the Lake George dam and the Galena River — the steelhead creeks are the easiest place to break the law by accident.
  • Rainbow smelt🚫 no-take
    On the Michigan and Wisconsin rough-fish lists. On Minnesota's waters of Lake Superior smelt is a dip-net and minnow-seine fishery under Minn. R. 6262.0300, not a spear one.
    • ⛔ 🚫 NEW YORK AND MINNESOTA: there is no spearfishing on these lakes at all. New York — ECL 11-1301: no fish may be taken except by angling, and the spear and speargun are permitted ONLY in the marine and coastal district, which does not touch the Great Lakes; in the state's freshwater regulations the spear appears only for FROGS. Minnesota — Lake Superior is a closed-list water: «fish may not be taken in Lake Superior except as provided by this part», and that part authorises no spearing method.
    • ⛔ 🚫 Lake sturgeon is protected in all eight Great Lakes states — endangered or threatened, no open season, possession prohibited. These species may not be taken by spear anywhere on the lakes.
    • ⛔ 🚫 Ohio's state endangered list is part of the shot: the cisco (lake herring) and the longnose sucker may not be possessed in any Ohio water, and alligator gar, shortnose gar and spotted gar are endangered even though «gar» sits in the forage-fish class — identify the fish before you shoot. Shovelnose sturgeon and goldeye are on the same list.
    • ⛔ 🚫 New York protects statewide: lake sturgeon, Atlantic and shortnose sturgeon, American eel (Lake Ontario / St. Lawrence), paddlefish, sauger, silver chub, gilt darter, mooneye, round whitefish and the longnose sucker — fishing for a listed species, catch and release included, is illegal. The spear is banned in New York fresh water anyway; this list is what binds a diver who crosses the state line.
    • ⛔ 🚫 Wisconsin: any sucker or redhorse listed as threatened or endangered falls OUTSIDE the rough-fish definition and may not be possessed without a DNR permit — the rough-fish permission is not a blanket one. Minnesota: black buffalo, paddlefish and skipjack herring are listed, so «buffalo» as a spear target must exclude the black buffalo.
    • ⛔ 🚫 Molluscs are not a target here: Indiana has banned native mussels — live animals and empty shells alike — since 1991, and Pennsylvania closes mussels and clams year-round.
    • ⛔ 🚫 Great Lakes wrecks are look-don't-touch. The Michigan Underwater Preserves and the Thunder Bay National Marine Sanctuary protect sunken vessels as monuments: removing anything from them is unlawful. In NATIONAL PARKS (Isle Royale) the state agency states it plainly — «Fishing in any manner other than hook-and-line is prohibited in National Parks» — so spearfishing there is out. For the national LAKESHORES (Sleeping Bear Dunes, Pictured Rocks) the superintendent's compendium was NOT read in this pass: treat their status as unverified.
    • ⛔ ⚠️ Ohio, Pennsylvania, Indiana and Illinois all publish ALLOW-lists: anything not on the list may not be taken. None of the four authorises a spear on any game fish — walleye, yellow perch, smallmouth bass, steelhead, lake trout, northern pike, muskellunge. And the status of Lake Michigan ITSELF in Illinois and Indiana was NOT confirmed in this pass: until the text is read, treat it as closed rather than open.

    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.

    Where do you get into the water at Highland Park?

    Four public access points carry the Highland Park forecast: Millard Beach (beach), Park Avenue Boating/Fishing Beach (beach), Rosewood Beach (beach) and Moraine 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 Winnetka, about 10 km away. Treat each one as a way into the water and read the bottom yourself.

    Season, water and wind at Highland Park

    From January to March the harbours ice up and the open lake does not. Plan the diving for June to October; visibility peaks from August to October. The southern end of the lake warms more at the surface than the Wisconsin shore, but under the summer thermocline the water stays cold, so thicker protection pays below a few metres. No tide: the astronomical range on the Great Lakes is a few centimetres, and wind and seiche set the level. At Highland Park the shore faces north-east (63°): wind and swell from 3–133° close it, worst from about 83°, so outside that arc the forecast is worth a look.

    FAQ

    Can you spear salmon, trout or perch at Highland Park?

    No. The 810(b) list holds no game fish, and Lake Michigan off Millard Beach is not among the waters 810(d) opens to spear methods.

    Can you spear from the beaches and piers at Highland Park?

    Illinois bars taking aquatic life along, upon, across or from any public right-of-way, and Millard Beach is public lakefront. Treat it as a swim and dive entry, not a place to hunt from.

    Where can you get into the water at Highland Park?

    From the mapped public entries: Millard Beach (beach), Park Avenue Boating/Fishing Beach (beach), Rosewood Beach (beach) and Moraine Park (beach). None of them is a surveyed dive site, and no depths are recorded.

    Which wind shuts Highland Park?

    Wind and swell from 3–133°, worst from about 83°: the shore by Highland Park faces north-east (63°). Outside that arc, Millard Beach and the other entries are worth a look.

    When is the season at Highland Park?

    June to October, best visibility August to October. From January to March the harbours ice up, so Millard Beach, Park Avenue Boating/Fishing Beach, Rosewood Beach and Moraine Park are a summer-and-autumn plan.
