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
Leave your email — and the moment a window opens at Point Lookout, we'll send the go / no-go verdict. Email is all we need.
Every covered town has its own live forecast, cameras and entry points. Choose where you're diving.

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.
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: 1391 spots across 205 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 mapDNR clam-shell reef off the point, about 3 m. Low structure that gathers sheepshead and tautog; brackish water keeps visibility short almost all the time.
Google MapsCameras, map and reference — to hand as you come up.
SpainRiprap at the Potomac–Chesapeake confluence, about 1 m. Sheepshead and tautog on the stone; hold the 100-yard clearance from swimmers and the pier, and remember striped bass is spear-banned.
WARNING: this reef lies inside the Point Lookout-Cedar Point firing-range danger zone (33 CFR 334.200) - patrol craft may order you out at any time. A 1059-acre reef in 9-11 m: two barges and Woodrow Wilson bridge rubble, holding striped bass and black sea bass.
Google MapsWARNING: WWII German U-boat in the lower Potomac at about 20 m — a federal and state Historic Shipwreck Preserve where diving is allowed but taking anything is not. Information zone only.
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.
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.
Point Lookout has rock entry points such as Point Lookout tip riprap/breakwater, Point Lookout Reef and U-1105 "Black Panther" wreck. Point Lookout guards the Potomac–Chesapeake confluence — riprap, a DNR reef and the WWII U-1105 wreck (a protected preserve) for sheepshead and tautog. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Jun–Oct at the Chesapeake mouth; no striped bass, 100-yard no-shoot rule.
Turbid Chesapeake mouth; clearer offshore, 18–25 °C.
Intermediate: strict 100-yard no-shoot rule (people/flags/vessels), no striped bass.
Yes — in Point Lookout 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.
