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.
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 Hampton, 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 mapLedges off the rocky drumlin headland at the north end of Hampton Beach, 2–8 m. Tautog and striped bass; the geography checks out but dive reports are thin — scout it carefully.
Google MapsTwin rock jetties at the Hampton River mouth over ledge, 2–8 m. Tautog and striped bass; New Hampshire has no written spear ban on bass — WARNING: confirm with the Marine Division first.
Google MapsLedge and boulder shoreline under the Little Boars Head bluff in North Hampton, 2-9 m. Tautog and cunner in the rock through the warm months; parking is tight along Ocean Boulevard and the entry is over slick granite.
Google MapsRock and cobble cove at the north end of Hampton, 2-8 m with weed-covered ledge running offshore. Cunner, pollock and flounder over the mixed bottom; roadside access, fully open to an easterly sea.
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.
Hampton has rock entry points such as Hampton Harbor Inlet Jetty, Great Boars Head Ledges and Plaice Cove. Hampton fishes the Hampton River inlet jetties and the Great Boars Head ledges off Hampton Beach — tautog and striped bass on the rock. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Tiny coast, a Jul–Sep window in the summer calms.
Cold, 10–16 °C in summer; viz best on flat days.
Intermediate–advanced: cold, short season, dive the calms.
Yes — in Hampton 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.
