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».
National minimum sizes + a 150 g floor (in the table below); grouper 1/day. Spearfishing is closed all May (ΠΔ 373/1985).
Rules change, and the local Λιμεναρχείο (port authority) may impose local restrictions. Before heading out, check the current rules and the declared archaeological zones (ENALIA).
Spearfishing Astypalaia is a wind-management problem. The island has bays, inlets and satellite islets, but the NW meltemi can make open crossings and exposed shores a bad plan. Maltezana is the practical sheltered bay, Vathy is the deep all-wind inlet, Livadi and Pera Gialos work on a northerly, and Koutsomitis/Kounoupa is a boat-only clear-water option when the crossing is settled.
Keep the list compact and weather-led. Maltezana is the main sheltered bay, Vathy is the enclosed fjord-like option, and Koutsomitis/Kounoupa is the clearer islet ground when boat conditions are genuinely calm.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Maltezana / Analipsi bay | Sheltered bay and islets | 0-20 m | Intermediate | Shore or boat | Main dive area with islet shelter. Check anchorage traffic before committing. |
| Vathy fjord | Deep enclosed inlet | 0-25 m | Intermediate, remote | Shore or boat | Very sheltered in all winds, with deep water close in and a remote NE setting. |
| Koutsomitis / Kounoupa islets | Rocky islets and reef | 5-25 m | Boat, settled weather | Boat | Clear-water islet ground with exposed crossing. Do not force it in wind. |
The NW meltemi pushes the plan toward S, SE and E lee. Maltezana and Vathy give the safest named shelter; Livadi/Pera Gialos can work with a northerly; Agia Kyriaki/Vatses is exposed to south wind. Greek legal baseline: May is totally banned (ΠΔ 373/1985); no licence since 2014; freediving-only; 5 kg/day. Natura 2000 advisory zones require a local-rules check.
No. The old recreational licence is gone since 2014; check the current state sign-up before travelling.
Yes. The national May spearfishing ban applies to Astypalaia under ΠΔ 373/1985.
In NW meltemi, start with Maltezana or Vathy, then only consider exposed islets if the sea is clearly settled.
Yes, several listed spots allow shore access, but the island is remote and windy, so inspect exits first.
Not automatically. They are protected marine advisory zones, so check local rules and boundaries before fishing.
