Today — sit it out — 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
Leave your email — and the moment a window opens at Yarmouth, we'll send the go / no-go verdict. Email is all we need.

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: 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.

In British Columbia spearfishing while diving is allowed for finfish except salmon, with a Tidal Waters Sport Fishing Licence; Rockfish Conservation Areas, Pacific Rim NPR and named DFO closures (e.g. Ogden Point, Race Rocks, Whytecliff) are closed. In Atlantic and Quebec tidal waters groundfish and mackerel may be taken only by angling or hand-line (AFR s.15(2)) — treat spearing as not permitted. Check current rules locally.

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.
Yarmouth has rock entry points such as Cape Forchu, Port Maitland and Chebogue Point. SW Nova Scotia at the mouth of the Bay of Fundy: Cape Forchu's ledges, the Tusket Islands and the lobster grounds of the Gulf of Maine.
