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 in Lesbos is best planned around shelter. Gera and Kalloni are near-landlocked gulfs with softer bottom, lower visibility and tsipoura, lavraki and octopus. The open rocky coasts are clearer and suit grouper, dentex and sargos, but the north coast suffers in N/NE meltemi. May is a total spearfishing ban across Greece (ΠΔ 373/1985), and no spearfishing licence has been issued since 2014.
Use the gulfs for shelter and the open rock only when the wind allows. The wreck entries are boat-led and should not be treated as beginner shore dives.
| Spot | Type | Depth | Level | Access | Notes |
|---|---|---|---|---|---|
| Charamida / Agios Vassilios | Islets and rocky reef SE of Mytilene | 5-25 m | Moderate exposure | Shore or boat | A meltemi-sheltered rocky option near Mytilene. |
| Gera & Kalloni Gulfs | Sand, seagrass and rocky edges | 2-15 m | Sheltered, lower visibility | Shore | The all-wind fallback for tsipoura, lavraki and octopus. |
| Cape Agios Fokas Shipwreck | Shallow wreck on the south coast | 5-17 m | Boat and calm exit | Boat | Leeward in meltemi near the Kalloni mouth. |
| Petra / Myrmigi Reef | North-coast reef complex | 15-21 m | Calm dawn only | Boat | Clearer water, but exposed to N/NE meltemi. |
The useful Lesbos window is June and September to October. May is closed by national law, so there is no legal May workaround. In summer, read wind first: if N/NE meltemi is working, the north coast around Molyvos and Petra is the wrong side, while Vatera, Agios Fokas and the enclosed gulfs make more sense. Greek rules also require freediving only, no scuba or compressed air, and a daily catch limit of 5 kg per person.
No spearfishing licence has been issued in Greece since 2014. Check gov.gr before travel for the recreational-fisher registry.
Yes. May is a total spearfishing ban across Greece, including Lesbos.
Use Vatera, Agios Fokas or the Gera and Kalloni gulfs when N/NE wind makes the north coast poor.
The gulfs suit tsipoura, lavraki and octopus; clearer open rock adds grouper, dentex and sargos.
No. Spearfishing in Greece is freediving-only; scuba and compressed-air gear are banned.
