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.

SOLO 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.

  • dog snapper / pargo
    3–15 m · tide change — moving water · dusk/night
    Hard-fighting reef snapper around rocky points & pinnacles; ambush on the tide change, best at dusk/night. Peaks in the warm months. Mexican rule sets no minimum size.
  • leopard grouper
    5–25 m · tide change — moving water · daytime
    Leopard grouper on rocky reef, by day. Forms spawning aggregations in spring (Apr–Jun) — very vulnerable then, take sparingly. No minimum size in the rule.
  • white seabass
    3–20 m · tide change — moving water · dawn/dusk
    White seabass over reef & kelp edges; spring peak, best at dusk on moving water. No minimum size in the rule.
  • California sheephead
    3–20 m · tide change — moving water · daytime
    California sheephead on rocky reef, by day; resident, best in the warm months. Roots the bottom — approach slowly. No minimum size in the rule.
  • yellow snapper
    3–15 m · tide change — moving water · dusk/night
    Yellow snapper by rocks & estuary edges; warm months, best at dusk/night on the tide change. No minimum size in the rule.
off season: yellowtail (Dec Jan Feb Mar Apr May) · Pacific sierra (Nov Dec Jan Feb Mar Apr)
Not a target — don't shoot
  • mahi-mahi / dorado⚠️ release / rod-only
    ⚠️ Reserved for rod-and-reel in the 50-mile belt — conservatively DON'T spear it (the exact DOF wording isn't quoted).
  • roosterfish⚠️ release / rod-only
    ⚠️ Reserved for rod-and-reel in the 50-mile belt — conservatively DON'T spear it (the exact DOF wording isn't quoted).
  • totoaba🚫 no-take
    🚫 Totoaba — permanent no-take (moratorium since 1975, NOM-059 'P', CITES I). Do not take, release.
Law
  • 🚫 Sport spearfishing is fish-only: lobster, conch (caracol) and octopus may NOT be speared (squid is the sole exception). §4.2.
  • 🚫 Totoaba, sea turtles, marine mammals and corals — no-take (). Inside the national parks (Cabo Pulmo, Cozumel, Puerto Morelos, Revillagigedo) all hunting is banned.
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 Zihuatanejo: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Spearfishing in Zihuatanejo is not one single bay spot. Isla Ixtapa offers island reef but has protected sectors that must stay out of the hunt. Morro del Chato and Sacramento are rocky boat options. Los Morros de Potosí are granite pinnacles with strong current and real depth. The Mexico baseline applies everywhere: CONAPESCA/SADER permit, apnea-only spearfishing, one speargun, no tank, and no spearing of roosterfish or mahi-mahi.

TL;DR

  • Zihuatanejo is a south-facing Pacific setup with island reef, protected sectors and strong-current granite pinnacles.
  • Mexico requires the CONAPESCA/SADER permit and spearfishing is freedive-only. Do not use scuba with a speargun.
  • Isla Ixtapa only makes sense outside protected cores. Los Morros de Potosí are for experienced divers.
  • Use the Ixtapa cameras for a first read, then decide from south swell, current and the boatman's call.

Best spearfishing spots in Zihuatanejo

The working spots split into sheltered island reef and more serious offshore rock. Treat each pin as approximate. For visitors, the first question is not target fish; it is whether the site is outside protected sectors and whether the current is manageable.

SpotTypeDepthLevelAccessNotes

Los Morros de PotosíGranite pinnacles9 to 37 mAdvancedBoat south of ZihuatanejoStrong current and deeper drops. Go only with a local boat that knows the pickup angles.
Morro del Chato (Zihuatanejo)Rocky reef6 to 22 mIntermediateBoat, outside reservesRock for cabrilla, pez fuerte, barracuda and grouper. Coordinates are approximate.
Sacramento A/B (arrecifes)Current-swept reef8 to 25 mIntermediate to advancedBoatWorth considering only when the south pulse is down and the current is readable.

Spearfishing Zihuatanejo conditions today

The coast is south-facing, and the bad swell window runs broadly from south to west. That can shut down Los Morros and the open reefs before the bay looks ugly from town. Ixtapa beach cameras are useful for surface colour and set timing, but they do not tell you whether a pinnacle is running. Start with the cameras, then ask the boatman about current and pickup.

Underwater visibility in Zihuatanejo today

There is no local buoy connected for Zihuatanejo. Visibility is a practical read from south swell, recent wind and water movement across the reef. If Ixtapa is milky, do not expect Los Morros to improve by force of optimism. When the water clears but the current pulls hard, stay shallow or change the plan.

What fish can you spear in Zihuatanejo?

The Pacific Mexico list includes dog snapper, leopard grouper, yellowtail, Pacific sierra, white seabass, California sheephead and yellow snapper. Snapper work rocky points and pinnacles on moving water. Cabrilla sit in rock by day. Yellowtail and sierra lean cooler. Roosterfish and mahi-mahi are not speargun targets under the conservative Mexico rule, and the same goes for marlin, sailfish, swordfish and tarpon.

Protected sectors of Isla Ixtapa spearfishing allowed

Do not spear inside the protected sectors. Isla Ixtapa needs a zoning check before it becomes a hunting plan. A local operator should be able to point out the closed cores and keep the boat outside them. If that boundary is unclear, choose a different site. Los Morros carry a different warning: strong current and experience required.

CONAPESCA permit and apnea-only rules

The CONAPESCA/SADER recreational-sport permit is personal and handled through E5CINCO. Use the portal for the current fee and duration options. Spearfishing is breath-hold only: one band or pneumatic speargun, no hooks or tridents, no tank, and a five-fish daily limit. Keep clear of swimmers and commercial gear. Lobster, conch and octopus are not sport spearing targets.

FAQ

Where can you spearfish in Zihuatanejo?

Isla Ixtapa outside protected sectors, Morro del Chato, Sacramento and Los Morros de Potosí. Los Morros are advanced because of current.

What is the underwater visibility in Zihuatanejo today?

It depends on south swell, wind and current. Use the Ixtapa cameras as a first read, then confirm from the boat.

What fish can you spear in Zihuatanejo?

Dog snapper, leopard grouper, yellowtail, Pacific sierra, white seabass, California sheephead and yellow snapper. Do not spear roosterfish or mahi-mahi.

Can you spearfish in the protected sectors of Isla Ixtapa?

No. Hunt only outside the protected cores and verify the boundary before entering.

When is the best season to spearfish in Zihuatanejo?

Warm months favour snapper; cooler months favour yellowtail and sierra. Daily south swell and current are the real filter.

Do you need a permit to spearfish in Mexico?

Yes. Carry the individual CONAPESCA/SADER recreational-sport fishing permit.

How much is the CONAPESCA permit and where do you get it?

Get it through E5CINCO and use the portal for the current fee. Do not plan from copied numbers.

Is scuba spearfishing allowed in Mexico?

No. Mexico spearfishing is apnea-only; do not combine a tank and speargun.
