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 Northport, 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 mapReef and ledge off Eatons Neck below the lighthouse, about 7 km north of Northport Harbour, 2–9 m. Current-swept tautog and scup; plenty of recreational boat traffic.
Google MapsNYSDEC artificial reef on the Long Island Sound bottom 1.16 nm northeast of Lloyd Point, 14-16 m over concrete and rock rubble. Boat access only; work the slack, the Sound runs hard here, and tautog and black sea bass hold on the structure from late spring to autumn.
Google MapsShore access point Lloyd Neck, roughly 12 km from Northport. Marker position: 40.942° N, 73.476° W. Depths reach about 1.0 m. Tides are semidiurnal, two highs and two lows a day.
Google MapsOfficial Long Island Sound reef about 14 km to the east in Smithtown Bay, in roughly 12 m. Tautog, black sea bass and scup over structure deployed by the state.
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.
Northport has rock entry points such as Smithtown Reef, Eatons Neck Point and Huntington/Oyster Bay Reef. Northport works Smithtown Reef and the Eatons Neck ledges in Long Island Sound — current-swept tautog, scup and black sea bass. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Jun–Oct; striped bass legal, but the 100-yard public-beach rule applies.
16–22 °C in summer; viz poor (bays) to decent (ocean side).
Intermediate: mind the 100-yard beach rule and boat traffic.
Yes — in Northport 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.
