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».
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.
Spearfishing in Venice, Florida is boat-based reef diving over a warm Gulf shelf. M-15 is the close inshore relief, Sarasota Sportsman Reef M-17 is the mid-shelf snapper stop, and M-9 Reefex #3 offers higher reef-ball relief. Hogfish, sheepshead, snapper, legal grouper, cobia and flounder can be part of the plan when open. The legal filter is strict: follow FWC spearing rules and confirm seasons before running offshore.
The three sites step up by commitment. Start with M-15 for a short-run check, move to M-17 for mid-shelf structure, and save M-9 for settled days. A pretty beach does not guarantee good bottom visibility offshore.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| M-15 Reef | Close inshore artificial reef | About 8 ft of relief | Intermediate | Boat access off Venice | A short-run visibility test with modest relief and strict legal target selection. |
| Sarasota Sportsman Reef M-17 | Mid-shelf artificial reef | Moderate shelf depth | Intermediate boat dive | Boat access offshore | A snapper-minded reef; confirm season, size and SRFS status. |
| M-9 Site Reefex #3 | High-relief reef balls | Higher relief structure | Advanced boat dive | Longer offshore run | Better relief and more commitment. Use a disciplined ascent and boat-watch plan. |
The bad sector is about 215-300 degrees, with west around 260 degrees stirring the shelf. Light east wind and stable weather help push cleaner water offshore. NOAA station 42013 and Venice beach cams work best together.
The regional list includes sheepshead, mangrove or mutton snapper, hogfish, cobia, flounder and gag or red grouper when open. Grouper seasons change, so check before the run. Shoot only identified, legal fish with enough size margin.
Carry a saltwater license and SRFS for reef fish. FWC prohibits powerheads and rebreathers, and bars spearing many species including snook, red drum, spotted seatrout, tarpon, sharks, rays, billfish, goliath grouper, Nassau grouper, lobster and stone crab.
M-15 is the reality check. If it is dirty or surgey, do not assume M-17 or M-9 will be easier. If it is clean, use the longer run only with enough daylight and fuel margin.
