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 Tuxpan is centered on the Lobos-Tuxpan reef system, not the beach. The listed reefs sit about 10-15 km offshore and usually offer cleaner water, but they are coral and ANP-sensitive. Isla de Lobos/Sistema Lobos-Tuxpan is listed in 3-12 m. Tanhuijo, Blake and Enmedio are 3-20 m coral reefs marked as legal but inside or near an ANP buffer, so verify zoning before loading a gun. From October to March, Nortes bring strong north wind and short sea; wait until the front passes. Mexico requires a CONAPESCA/SADER permit, apnea only and five fish per day.
Use the reef names as navigation references, then confirm the legal subzone and coral rules before fishing.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Isla de Lobos / Lobos-Tuxpan system | Offshore coral reefs | 3-12 m | Intermediate; boat-based | 10-15 km offshore | Main reference for spearfishing Tuxpan. Confirm entry, pickup, subzone and coral distance. |
| Arrecife Tanhuijo | Coral reef | 3-18 m | Intermediate with zoning check | Boat inside the reef system | Huachinango, grouper and snapper are listed. Do not shoot if ANP permission is unclear. |
| Arrecife Blake | Coral reef | 4-20 m | Intermediate | Boat, subzone to verify | Good structure, but no contact with coral and no shooting in uncertain polygons. |
Nortes are the main seasonal filter. From October to March, strong north wind and short sea can close the offshore reefs; wait until the front has passed. There is no nearby buoy nearby, so combine local forecast, harbor observation and boat recovery planning.
Yes. Several reefs are inside or near ANP buffers; if the subzone is unclear, do not shoot.
Yes. October-March Nortes can bring strong north wind and short sea.
Yes. Mexico requires an individual recreational sport-fishing permit.
No. Spearfishing is apnea only.
No. Keep clear of coral; if coral or boundaries are uncertain, do not shoot.
