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 — where night spearfishing is banned by law the window is forced red; where it is legal (Australia outside NSW, New Zealand, South Africa) it is capped at yellow, never green.

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.

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.

Law

✓A is required — tourists included (apply at the Oficina de Permisos).
✓Nassau and goliath grouper are closed year-round; parrotfish and queen conch (carrucho) are protected (federal + ).

⛔ 🚫 Nassau grouper (cherna) and goliath (guasa), plus queen conch (carrucho) — federal no-take. Lobster may NOT be speared (Art. 8.18) — hand/trap only.
⛔ 🚫 Sea turtles, marine mammals and Acropora corals — no-take (ESA). Spearfishing is banned in marine reserves (Tres Palmas, Canal Luis Peña), bathing zones and within 100 ft of shore.

Rules change. Before heading out, check with the DRNA (Departamento de Recursos Naturales y Ambientales) and the federal NOAA rules (50 CFR 622).

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 Humacao: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Humacao spearfishing revolves around Palmas del Mar reefs, The Cracks, Cayo Santiago and nearby Naguabo or Yabucoa options. The east trade wind is the main filter: if it is up, the reef may be choppy even when the marina looks calm. The Reserve sits around 12-24 m; The Cracks is a more advanced 18-21 m ledge with possible sharks. Carry a DRNA recreational licence, keep the spear more than 30 m off the coast, and hunt on breath-hold only. Night work is for lionfish. Cayo Santiago is no-landing, and unclear reserve status means closed.

TL;DR

Humacao is an east-face plan: trade wind chop decides whether Palmas del Mar reefs are usable.

A DRNA recreational licence is required for visitors; spearfishing is breath-hold only, not scuba-assisted.

Cayo Santiago has no landing because of the primate reserve. Any reserve uncertainty should fail closed.

Best spearfishing spots in Humacao

Use The Reserve for intermediate reef, The Cracks only with a capable buddy, and Cayo Santiago only with full respect for the no-landing rule and any management restriction.

Spot	Type	Depth	Level	Access	Notes
Palmas del Mar reefs (The Reserve)	Reef	12-24 m	Intermediate	Boat or organized launch	Legal grouper, snapper and hogfish in clear water. East wind chop can ruin the window.
The Cracks / Retreat	Reef ledge	18-21 m	Intermediate to advanced	Boat	Good structure with possible sharks. Do not use it as a casual second stop.
Cayo Santiago	Cay reef	3-15 m	Intermediate	Boat, no landing	Nearby water is dived, but the island is a primate reserve. Fail closed if rules are unclear.
