Today — right on the edge — wave, wind and surge pounding.

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 in the appFront Beach: you go in from the shore, some 0.4 km from Rockport (MA). The pin sits at 42.659 N / 70.621 W on the chart. Depths reach about 9 m. NOAA soundings step from about 2.2 m at 50 m off the marker to 8 m at 200 m. Bottom type: sand and rock.
Google MapsEntry from the beach at Halibut Point, 4.1 km out of Rockport (MA). Coordinates of the entry: 42.692 N, 70.628 W. Expect no more than about 9 m of water. Heading out to the north-east, the bottom is about 6 m deep 50 m from the marker and 12 m at 200 m.
Google MapsGranite ledges and old quarry shoreline at Cape Ann's northern tip, 2–15 m, with rock shelves and tide pools. Wide open to a northerly sea; tautog and cunner. Parking at the state park. Pin: shore access; water entry unverified.
Google MapsHoop Pole Cove is a shore entry about 3.7 km from Rockport (MA). The pin sits at 42.689 N / 70.624 W on the chart. The deepest water here is close to 9 m. On a line to the north-east, NOAA bathymetry gives roughly 6 m at 50 m and 11 m at 200 m out.
Google MapsRocky cove on the Cape Ann back shore south of Land's End, 2-12 m over ledge and kelp. Tautog and pollock work the ledges; entry is over slippery granite and the cove takes any easterly swell straight in.

Open in the appYou can walk into the water at Pebble Beach; the town of Rockport (MA) is 2.8 km away. Coordinates of the entry: 42.635 N, 70.601 W. Maximum depth is around 5 m. On a line to the south, NOAA bathymetry gives roughly 4 m at 50 m and 6 m at 200 m out.

Google MapsLedges at the entrance to Rockport Harbour around the lighthouse islet, 2–10 m. Sheltered from swell, so it is the pick on messy days — tautog and cunner over stone. This mark sits at the access point on land — where to enter the water is unconfirmed.
Google MapsEntry from the beach at Whale Cove, 2.1 km out of Rockport (MA). Marker position: 42.653° N, 70.595° W. Depths reach about 7 m. NOAA soundings step from about 6 m at 50 m off the marker to 9 m at 200 m. Bottom type: boulders and ledges.
Google MapsBoulder field around the twin-lighthouse island off Rockport, 3–15 m — plenty of lobster (never legal by spear in MA), plus cod and pollock. Boat only; the stated depth is approximate. Pin: shore access; water entry unverified.
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.
Check the cam BEFORE you leave. Foam, brown/green murk, or waves washing the entry rocks = No-go. At night/in fog the cam is useless — treat it as «unknown», NOT «green».
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.
Rockport (MA) has rock entry points such as Halibut Point Ledges, Thacher Island and Straitsmouth Island. The tip of Cape Ann at Rockport — Halibut Point, Thacher and Straitsmouth Island ledges for cod, tautog and lobster. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Jun–Oct; Cape Cod and the islands, tautog and black sea bass.
Cool, 12–18 °C; moderate viz, best off the islands.
Intermediate: cool with headland current, best off the islands.
Yes — in Rockport (MA) almost certainly, but the licence is the STATE's, not a federal one: nearly every coastal state requires its own saltwater fishing licence, and several add a free registration or an extra endorsement on top (Florida's free State Reef Fish Survey for reef fish, Texas's saltwater endorsement, California's Ocean Enhancement Validation). Hawaii asks nothing of residents and charges visitors the NRMFL. What may be speared, and with what gear, is state law too — the price and the details depend on the state, so read the «Law» block below.
