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.

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 Indian River Inlet is less about distance from the beach and more about timing the water. The inlet jetty funnels current hard, so slack water is the only sensible window for a freediver. The nearshore DNREC reef site and Reef Site 10 are better boat targets when the Atlantic is settled, with concrete, tires, wreck pieces and barges holding tautog, black sea bass, sheepshead and flounder. For Indian River Inlet water visibility, watch east swell, tide stage, wind over the bridge, and NOAA station 44009.
The inlet is not a beginner drift. Shore entries need a fixed exit plan and should be skipped when current is still running. The offshore reefs are more predictable for hunting, but they require a competent boat crew and clear diver-down discipline.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Indian River Inlet Jetty | Rock jetty and inlet mouth | Shallow to moderate along the rocks | Intermediate to advanced | Shore access only at slack water | Tautog, sheepshead and flounder use the rocks. Do not enter on a moving tide or when east swell is hitting the jetty. |
| DE Reef Site nearshore | Official DNREC artificial reef | About 50 to 60 ft | Boat crew, intermediate | Boat from Indian River Inlet | A practical spearo target about 5 miles off the mouth. Expect reef fish on low relief structure rather than natural ledges. |
| Delaware Reef Site 10 | Artificial reef with units and wreck material | Moderate offshore reef depth | Boat crew, intermediate | Boat, roughly 6 to 7 miles out | Tautog and sheepshead are the reason to go. Pick the calmest sea state because the bottom is exposed to Atlantic swell. |
Slack tide is the deciding factor at the jetty. A pretty surface during a ripping exchange can still be unsafe because the bridge throat accelerates the flow. The Atlantic side faces roughly east, so swell from 40 to 150 degrees is the visibility killer and the exit problem. NOAA station 44009 gives a regional sea check, while the DelDOT inlet cameras show whitewater, bridge wind and boat traffic. If both disagree with the forecast, trust the camera and stand down.
Tautog are the classic rock and wreck target, especially tight to concrete, tires and jetty stone. Black sea bass and scup belong on the deeper reef list, while summer flounder can be found around sand breaks and low structure. Bluefish and striped bass pass through, but each species still has Delaware seasons, sizes and possession limits. Sturgeon are fully protected, and American lobster is not a spear target anywhere on this coast.
Delaware is not New Jersey, Maryland or Maine; use DNREC rules for the exact date and species. The practical rule set is simple before launch: hold the correct recreational license or exemption, be fully submerged when using a spear, respect daily limits, and keep reef-site hunting within legal methods. Striped bass rules change often across the Atlantic states, so confirm the Delaware line before treating bass as available. When an inlet closure or posted restriction is unclear, fail closed.
No. The current makes it an intermediate or advanced slack-water spot, not a first shore dive.
NOAA NDBC station 44009 is the listed offshore reference for this inlet.
The DNREC reef system is built for fishing and diving. Still check current species and gear rules before each trip.
East and northeast swell are the main problem because the coast and inlet mouth face that energy.
No. Lobster is never a spear target on this coast; use only legal hand-take rules where allowed.
