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.
Cameras, map and reference — to hand as you come up.
Check the cam BEFORE you leave. Foam, brown/green murk, or waves washing the entry rocks = No-go. At night/in fog the cam is useless — treat it as «unknown», NOT «green».

Rules change and are REGIONAL. Before heading out, check with the competent autonomous community (licence) and the min-size table in force.
L'Ametlla de Mar is a rocky-cove shore-entry area. Cala Forn, Cala del Vidre and Cap Roig all depend on how much easterly sea is running; the harbour rock at Cala Calafató is the easier, semi-sheltered start. Legally it is Catalonia and the Mediterranean caladero: use the Catalan underwater recreational licence, freedive only, carry a buoy, and keep away from protected or uncertain artificial-reef zones.
These shore-entry zones should only be used with settled sea, a visible buoy and confirmed local limits.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Roquedo del port (Cala Calafató) | Rocky ground by the harbour | Shore rock in shallow water | Careful beginner | Easy shore entry | Semi-sheltered rocky entry, good for beginners. Small sea. Stay out of port waters. |
| Cala del Vidre | Rocky coves toward L'Ampolla | Mixed shallow bottom | Intermediate | From the cove, away from bathing areas | Rocky coves and mixed bottom. Moderate east exposure. Catalan licence required. |
| Cala Forn | Rocky cove south of L'Ametlla | Rock ledges and drop-offs | Intermediate | From the cove, away from bathing areas | Rock, Posidonia, sargo and gilthead. Poor in Llevant. Mediterranean sizes apply. |
| Cap Roig | Rocky ground at Cap Roig | Deep rocky ledges | Intermediate | Shore entry with a clear exit route | Deeper rocky ledges. Exposed to E-SE swell. Check protected-zone limits. |
The local coast faces east. The bad sector runs from 60 to 165 degrees, with the worst direction around 100 degrees, so easterly Llevant can quickly ruin visibility and entry comfort. Use the L'Ametlla harbour webcams because no NDBC buoy is listed for the city. Cala Forn has rock, Posidonia, sargo and gilthead but is exposed. Cala del Vidre is mixed rocky ground with moderate east exposure. Cap Roig has deeper ledges and should wait for a clean forecast. The Golf de Sant Jordi artificial reef is marked as a protective reef with likely restrictions, so do not use it as a spearfishing spot.

No. It is flagged as a protective reef with likely restrictions and should be checked before entering.
Catalonia sets grouper at 50 cm, with a daily maximum of 2.
No. Catalonia lists elasmobranchs, sharks and rays, as prohibited catch.
