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).
Karpathos spearfishing is mostly a wind decision before it is a spot decision. The Karpathos/Kasos strait drives the northerly hard, so Diafani, Saria and the far north can be wild pelagic water or simply unfishable. The steadier plan is the SE/E lee around Pigadia, Achata, Amoopi and Kastelia. May is a total spearfishing ban in Greece, so the local late-May sea window does not create legal fishing days.
The recorded spots point to one usable pattern: stay in the east and southeast lee when the northerly is running. There are no safety ratings in the Greek registry, so the level field only follows the wording in each spot description.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Achata Cave | Cave in a sheltered bay | Shallow to moderate, inside the cave and bay | Easy entry | Shore | East lee with a sheltered bay. It is the clearest shore option in the Achata group when you want a land entry. |
| Amoopi (SE) | Reef in SE bays | Shallow to moderate, over the reef | Beginner-friendly | Shore | Described as the best sheltered lee. The Amoopi bays are the first place to check when north wind is shaping the day. |
| Kastelia (SE) | Reef next to Amoopi | Shallow to moderate, along the reef | - | Shore | Southeast and sheltered. Treat it as the same lee logic as Amoopi, not as a separate promise of safer or deeper water. |
| Achata Arch | Arch and reef | Deeper structure, kept qualitative here | - | Boat | East coast north of Pigadia, in the eastern lee. It is a boat spot, so do not plan it as a shore fallback. |
| Swallow Cave | Cave on the NE coast | Shallow to moderate, around the cave | - | Boat | Recorded as a boat-access cave on the northeast coast. Use it only with a day and crew that fit that access. |
Karpathos is one of the windier Greek islands in this dataset. The Karpathos/Kasos strait funnels the northerly hard, and the far north around Diafani and Saria can turn into rough pelagic water. With north wind, the working plan is the SE/E lee: Pigadia, Achata, Amoopi and Kastelia. Saria Palatia Bay also sits in a Natura 2000 marine zone with an advisory flag, not an automatic hard no-take in the sheet, so boundaries and local rules still need checking before a boat run.
The city blurb names wild blue water, greater amberjack, dentex and grouper. The Dodecanese species list also includes white grouper, goldblotch grouper, white seabream, saddled seabream, Mediterranean barracuda, parrotfish and brown meagre. Grouper species in Epinephelus have a 45 cm minimum and a shared max of 1/day. White seabream is 23 cm, brown meagre is 25 cm, gilthead is 20 cm and octopus is 750 g. Dentex, amberjack, barracuda and parrotfish have the national 150 g minimum only in the sheet.
The local season note points to late May-June and September-October, with dawn as the steady time of day. The legal filter comes first: Greece has a total spearfishing ban for the whole month of May every year. That means the useful local window starts in June, not during the late-May part of the sea season. In autumn, September and October are the cleaner planning months from the fact sheet. On any date, wind direction matters more than a calendar label.
Greek national rules apply in Karpathos. No spearfishing licence is issued since the 2014 abolition under Law 4256/2014, but Greece is rolling out a free recreational-fisher registry, so check gov.gr before travel. Spearfishing is freediving-only: scuba or any compressed-air supply is banned and may not even be carried aboard. The daily catch limit is 5 kg, or one trophy over that limit. Grouper in Epinephelus is max 1/day. Night spearfishing and underwater light while hunting are forbidden.
Start with the SE/E lee: Achata, Amoopi, Kastelia and the Pigadia side. Achata Arch and Swallow Cave are boat spots, not shore entries.
The fact sheet names greater amberjack, dentex and grouper as the local big-fish angle. Grouper species in Epinephelus carry a 45 cm minimum and a max of 1 fish per day.
The north wind is accelerated by the Karpathos/Kasos strait. It often pushes the north and Saria out of play, while the east and southeast lee stay more workable.
No spearfishing licence is issued since the 2014 abolition. Check gov.gr before travelling because Greece is rolling out a free recreational-fisher registry.
Yes. May is a total spearfishing ban across Greece every year under Presidential Decree 373/1985. The Karpathos late-May sea window does not override that law.
The daily recreational limit is 5 kg, or one trophy fish heavier than that limit. Grouper in Epinephelus has an extra max of 1 fish per day.
No. Greek spearfishing is freediving-only, and scuba or any compressed-air apparatus is banned. The rule also says it may not be carried aboard.
