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 Sarasota is a boat run to artificial reef and limestone structure. Gary Service Reef M-1 is the nearest offshore check, M-4 is the mid-shelf complex, and Bob Johnson Reef is the deeper high-relief choice. The city-center protected hit at Pansy Bayou is no-entry water, so it stays outside any harvest plan. Use Gulf reefs, not protected bay shortcuts.
The reef sequence is simple: M-1 for the quick test, M-4 for a middle run, Bob Johnson for deeper grouper-minded days. All depend on clean Gulf water, a clear legal target list and a boat crew that can stay over divers.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Gary Service Reef M-1 | Nearest offshore artificial reef | Shallow shelf structure | Intermediate | Boat access from Sarasota ramps | A first visibility check when east winds have settled the Gulf. |
| M-4 Site | Mid-shelf reef complex | Moderate offshore structure | Intermediate to advanced | Boat access offshore | Useful when nearshore water is sandy but the crew does not want the longest run. |
| Bob Johnson Reef | Deeper high-relief reef | Deeper artificial structure | Advanced boat dive | Longer offshore run | The grouper-minded option; seasons and depth discipline decide the day. |
The rough sector is about 215-300 degrees, with west near 260 degrees stirring the shelf. Light east wind can flatten nearshore water and clean the reefs. NOAA station 42013 and local beach cams help separate good offshore days from brown-water beach days.
Pansy Bayou No Entry Zone is marked as a hard protected hit near the city center. Do not stage, enter or hunt there. If a protected boundary is unclear, fail closed and keep the speargun unloaded.
Targets can include sheepshead, snapper, hogfish, cobia, flounder and grouper when seasons allow. Florida prohibits spearing snook, red drum, spotted seatrout, tarpon, bonefish, sharks, rays, billfish, goliath grouper, Nassau grouper, lobster and stone crab. SRFS is required for reef fish.
Use M-1 as the condition check, not as proof that deeper reefs are safe. If M-1 is dirty or current-swept, M-4 and Bob Johnson are unlikely to become easier for the same crew.
No. It is marked as a hard no-entry protected zone.
Gary Service Reef M-1.
NOAA NDBC station 42013.
No. Florida prohibits spearing both.
Only with clean offshore conditions, enough depth experience and open seasons.
