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.
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: 1152 spots across 189 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.

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».
Rules change. Before heading out, check with the Bahamas Department of Marine Resources and the Fisheries Resources Act; spearguns are banned — sling/pole spear only.
Treasure Cay has rock entry points such as Treasure Cay barrier reef. Treasure Cay — famous beach and marina on mainland Abaco — fronts the sheltered Sea of Abaco with the barrier reef offshore. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Best in summer (May–Sep). The Sea of Abaco is sheltered by the barrier reef — there's almost always a diveable lee; no-take parks nearby.
Warm: ~28–30 °C in summer (lycra/2 mm), ~22–24 °C in winter (3 mm). The sheltered Sea of Abaco is often glassy.
Beginner-friendly: the Sea of Abaco is sheltered by the reef — there's almost always a calm lee.
In Treasure Cay the speargun is BANNED across all Bahamian waters (Fisheries Resources Act, CH.244) — only a Hawaiian sling or pole spear is legal, breath-hold only (no scuba or air of any kind), and the spear must be endorsed in writing on your fishing permit. Don't hunt within 1 mile of New Providence or the south shore of Grand Bahama, or within 200 yards of any Family Island; spearfishing competitions are banned. A shore guest without a boat is a gray area, so take a sportsfishing permit with a spear endorsement on entry. Nassau grouper is closed 1 Dec–28 Feb, crawfish 1 Apr–31 Jul; turtles and sharks are fully protected. See the guide.
