Today — right on the edge — wave, wind and visibility.

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 Westerly, 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.
See all spotsRelief and bottom type, tides, and the depths of each spot.
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 mapJetty-lined breachway into Quonochontaug Pond, the deepest and most saline of the Rhode Island salt ponds, 1-6 m along the walls. Tautog, black sea bass, scup and striped bass use the rock; the current through the cut is very swift, so dive it on the slack only.
Google MapsBoulder reef running about 700 m south of Napatree Point, marked by a bell buoy, 2–10 m. Tautog, scup and striped bass; swimmable from the point in flat conditions.
Google MapsDangerous reef south-west of Watch Hill Light, where the steamer Onondaga was lost, 3–15 m. Tautog, scup and striped bass; the current between the boulders is fierce.
Google MapsRock-jettied cut between Winnapaug Pond and the ocean, 1-6 m along the walls. Tautog and striped bass hold on the blocks and in the scour holes; the tide rips through the cut, so this is a slack-water dive and the deeper part of the flood is the only safe window.
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.
Westerly has rock entry points such as Watch Hill Reef / Watch Hill Light, Napatree Point Ledge and Weekapaug Breachway. Westerly dives Watch Hill Reef and Napatree Point Ledge — boulder reefs off Watch Hill for tautog, scup and striped bass. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Jun–Oct; striped bass is spearable here (unlike MA/CT).
Cool, 14–20 °C in summer; moderate viz.
Intermediate: accessible rocky shores, mind inlet current.
Yes — in Westerly 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.
