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.

Rules change. Before heading out, check with CONAPESCA/SADER (E5CINCO permit), CONANP (no-take marine ANPs) and NOM-059; apnea only.
Spearfishing in San Quintín is cold-water Baja Pacific, not tropical reef. Expect California Current water, kelp forests, variable visibility and a better autumn window. Useful spots are mostly boat-based: remote Colonet kelp reefs in 5-20 m, Isla San Martín in 5-22 m, Roca Ben in 12-30 m and Cabo Colonet in 5-18 m. Expect access difficulty, exposure and changing water color. Mexico requires an individual CONAPESCA/SADER permit, apnea only, one allowed speargun and a five-fish daily limit.
Pick San Quintín for kelp and remote rock, with boat recovery planned before entering.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Colonet reefs | Remote kelp reefs | 5-20 m | Upper intermediate | Boat, approximate coordinates | Cold kelp water with variable visibility; do not enter without a pickup plan. |
| Isla San Martín | Volcanic island reef | 5-22 m | Intermediate boat dive | Boat to the island | Listed outside reserves, with white seabass, kelp bass, California sheephead and barracuda. |
| Roca Ben | Outer rocky pinnacle | 12-30 m | Advanced; exposed | Boat to offshore pinnacle | Medregal, cabrilla, wahoo and tuna are listed. Use stable weather and a visible float. |
Visibility and cold water are the main filters. The area has variable visibility, better in autumn, and productive California Current kelp. Use enough exposure protection, confirm boat recovery and skip the dive if you cannot identify fish and bottom clearly.
Not mainly. The listed spots are remote or boat-based.
Autumn is autumn as the better visibility window.
Yes. Mexico requires an individual recreational sport-fishing permit.
No. Spearfishing is apnea only.
This guide uses the national five-fish daily limit.
