The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.
How we score the water
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.
- Swell & wave memory
- Height, period and direction of the swell, plus the wake of recent storms — an old storm still stirs the water, and the engine remembers.
- Wind & gusts
- Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
- Tide phase
- Timing and range of the tide, calibrated per coast — big spring tides pull the verdict toward caution.
- Water temperature
- Sea-surface temperature — sharply cold water vetoes a green verdict.
- Currents & outflow
- Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
- Rain runoff & air clarity
- Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
- Coast shape & exposure
- How the coast faces the swell — a sheltered cove keeps the water clean; an exposed, head-on point takes a penalty.
Safety gates
- Thunderstorm forecast — an instant red, no exceptions.
- An official warning (MeteoAlarm / IPMA) — yellow, or red for the higher ranks.
- Missing input data — a would-be green is capped to yellow rather than overstated.
- Strong disagreement between forecast models — a green day is pulled back to yellow.
- Night hours — forced red; the window is closed after dark.
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.

What it is
A marine instrument,
go / no-go for solo hunting.
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.

Reference
What's in season,
what the law says.
In season now
- red snapperRed snapper: state-set season (typically May–Oct), 2–4/day, 15–16″.
- sheepshead
- flounder
- cobia (ling)Texas: spear NONGAME only (sheepshead/flounder); gamefish (red drum/seatrout/cobia) pole-and-line only.
Law
- ✓Saltwater licence (+endorsement) per state: FL $17/$47, AL res $30, MS ~$13/$30, LA res $32, TX licence + saltwater endorsement.
- ✓Texas: spear only (sheepshead/flounder); gamefish (red drum/seatrout/cobia) pole-and-line only.
- ✓Red snapper: state-set season. Federal reef waters: spear + allowed outside the stressed area, descending device required.
- ⛔ 🚫 Goliath/Nassau grouper, Gulf sturgeon, sawfish, sea turtles, mammals and many sharks — take prohibited.
- ⛔ ⚠️ Texas & Alabama: gamefish (red drum/seatrout) pole-and-line only, NOT by spear. : banned in FL/TX, allowed in federal waters outside the stressed area.
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.
Safety protocol
- Sets: watch the wave trains ≥15 min before entering; Hmax ≈ 2×Hs, the wash can run 50 m past the foam line. A lull >10 min with period >12 s = a big set «overdue», do NOT enter; enter right after a full set passes and re-check at minute 30.
- Exit FIRST: find your exit AND a backup before entering. On a rocky/boulder shore a 0.5 m rise in swell can make the exit impossible — getting pinned/unable to climb out is the main killer.
- Headland rip: prominent points often have a permanent topographic rip regardless of the model — locate it, enter/exit on the windward side, never swim against it.
- Cold: wetsuit per the SST chip; the first shiver = a metabolic surge and a drop in breath-hold → get out at the first steady shiver. Cap the session at 45–60 min below 15 °C.
- Solo discipline: buoy up; tell someone the spot and exit time; conservative breath-hold (never push it in cold/murky/surfy water); visibility <3 m — don't enter.
- Afternoon wind: on many coasts the wind builds from midday — plan to be out of the water by midday; the chop builds — get out.
- UV 11:00–15:00 (UVI ≥6): sunscreen and cover up on the surface interval.
- Solo is a fundamental risk (hypoxic blackout with no buddy). Any doubt = No-go.
Spearfishing in Corpus Christi: spots, seasons and rules
Corpus Christi spearfishing starts with the rulebook before the reef list. Texas is stated plainly: spear nongame only, with sheepshead and flounder as examples, while gamefish such as red drum, seatrout and cobia are pole-and-line only. The local choices range from Packery Channel Jetties to MU-775 around 41 km out and MU-A-16 about 77 km out in roughly 76 m. That last mark is an advanced boat dive, not a casual second stop.
TL;DR
- Corpus Christi is the Texas-restriction page in this batch: spear nongame only, while red drum, seatrout and cobia are pole-and-line gamefish.
- The listed marks are Packery Channel Jetties, MU-775 Corpus Christi Reef and MU-A-16 Offshore Reef.
- Corpus Christi faces 120 degrees, with 80 to 170 degrees as the poor swell sector.
- A Texas license plus saltwater endorsement is listed; federal reef water has separate red snapper and descending-device language.
Which Corpus Christi spots match the Texas plan?
The three marks move from jetty rock to offshore reefed platforms and a deep Mustang Island Area reef. Because Texas species rules are narrow for spearguns, site choice and target choice cannot be separated.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Packery Channel Jetties | Rock jetty to bedrock | Jetty and bedrock; no numeric depth is stated | Intermediate, current-aware | Jetty access; confirm local entry and exclusion rules | Packery is the inshore rock option. It still needs clean water, low current and strict target discipline under Texas nongame-only spear rules. |
| MU-775 Corpus Christi Reef | Reefed platforms and ship | Offshore structure; exact depth not stated | Intermediate to advanced boat dive | Boat access; listed about 41 km offshore | MU-775 is the practical offshore reef in the city list. Treat the platform and ship structure as a boat-traffic and depth-management dive. |
| MU-A-16 Offshore Reef | Deep offshore reef | About 76 m is listed | Advanced boat dive | Boat access; listed about 77 km out in the Mustang Island Area | MU-A-16 is deep and far. It belongs to experienced crews with clear weather, not to marginal visibility days. |
What can you legally spear in Texas?
Texas allows spear for nongame only, naming sheepshead and flounder. Red drum, seatrout and cobia are gamefish and pole-and-line only. That means a Corpus Christi diver must identify before aiming, especially around jetties where mixed species move through.
How does weather sort the Corpus Christi options?
The aspect is 120 degrees, and the poor sector is 80 to 170 degrees. Southeast and east energy can make Packery rough and offshore structure uncomfortable. Buoy 42092 is listed 41.3 km away, and two Ozolio beach cameras help with surface checks.
What federal reef cautions apply offshore?
Red snapper is flagged as state-set, while federal reef waters have separate language: spear and powerhead outside the stressed area, plus a descending-device requirement. Texas state water also has its own powerhead warning, so do not blend jurisdictions casually.
Which protected Gulf wildlife matters off Corpus Christi?
Gulf rules bar Goliath and Nassau grouper, Gulf sturgeon, sawfish, sea turtles, marine mammals and many sharks. In Texas, the safer approach is to hunt the narrow nongame list and let unfamiliar fish pass.
