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 Steinhatchee, 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 mapBig Bend hard bottom in 7 m, with sheepshead and gag grouper. Warm, clear water in spring; in summer the algae and heat wreck the visibility.
Google MapsDeeper Big Bend zone about 35 km offshore in 10 m. Gag grouper and snapper; take spare fuel, because the coast is shallow and the run is slow.
Google MapsCameras, 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».
SpainLindberg cubes set on the Steinhatchee Fisheries Management Area public reef line, modules rising to about 8.5 m over sand at 10.7 m. Long run in a small boat from the Steinhatchee river mouth; hogfish, gag grouper and mangrove snapper, best from May to October when the Big Bend clears.
Shallow patches over Big Bend limestone ledge in 6 m. Sheepshead and grouper; the shelf falls away so slowly that it stays shallow kilometres offshore.
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.
Steinhatchee has rock entry points such as Steinhatchee Reef, Andree Reef #1 and SFMA Public Reef #1. Big Bend hard-bottom and scallop country: shallow limestone flats and reefs for grouper in tannic, tea-stained Gulf water that grades low on visibility. Below you'll find each spot (access, shelter and hazards) and today's forecast.
Year-round; the best US regime — snappers/groupers/hogfish, lionfish encouraged.
Warm year-round, 22–29 °C; the Keys and reefs are gin-clear.
Beginner-friendly on the reefs/Keys; mind the Upper Keys ban and the 100-yard rule.
Yes — in Steinhatchee 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.
