The verdict comes from seven water factors and hard safety gates — not ten tabs. Go or stay.

How we score the water

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.

Swell & wave memory
Height, period and direction of the swell, plus the wake of recent storms — an old storm still stirs the water, and the engine remembers.
Wind & gusts
Speed and gusts, hour by hour — wind speed and an onshore push chop the surface and cut visibility.
Tide phase
Timing and range of the tide, calibrated per coast — big spring tides pull the verdict toward caution.
Water temperature
Sea-surface temperature — sharply cold water vetoes a green verdict.
Currents & outflow
Direction and drift of the current — it pushes you, and it drags turbid coastal water across where you dive.
Rain runoff & air clarity
Rain muddies the water inshore through land runoff, while fog and haze cut visibility at the surface.
Coast shape & exposure
How the coast faces the swell — a sheltered cove keeps the water clean; an exposed, head-on point takes a penalty.

Safety gates

  • Thunderstorm forecast — an instant red, no exceptions.
  • An official warning (MeteoAlarm / IPMA) — yellow, or red for the higher ranks.
  • Missing input data — a would-be green is capped to yellow rather than overstated.
  • Strong disagreement between forecast models — a green day is pulled back to yellow.
  • Night hours — forced red; the window is closed after dark.

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.

What it is

A marine instrument,
go / no-go for solo hunting.

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.

SOLO 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.

  • Mediterranean monk seal (Monachus monachus) — strictly protected, keep your distance.
  • Sea turtles (Caretta caretta, Chelonia mydas) — protected, taking/disturbing is PROHIBITED.
  • Seahorses (Hippocampus) — protected.
Safety protocol
  • Sets: watch the wave trains ≥15 min before entering; Hmax ≈ 2×Hs, the wash can run 50 m past the foam line. A lull >10 min with period >12 s = a big set «overdue», do NOT enter; enter right after a full set passes and re-check at minute 30.
  • Exit FIRST: find your exit AND a backup before entering. On a rocky/boulder shore a 0.5 m rise in swell can make the exit impossible — getting pinned/unable to climb out is the main killer.
  • Headland rip: prominent points often have a permanent topographic rip regardless of the model — locate it, enter/exit on the windward side, never swim against it.
  • Cold: wetsuit per the SST chip; the first shiver = a metabolic surge and a drop in breath-hold → get out at the first steady shiver. Cap the session at 45–60 min below 15 °C.
  • Solo discipline: buoy up; tell someone the spot and exit time; conservative breath-hold (never push it in cold/murky/surfy water); visibility <3 m — don't enter.
  • Afternoon wind: on many coasts the wind builds from midday — plan to be out of the water by midday; the chop builds — get out.
  • UV 11:00–15:00 (UVI ≥6): sunscreen and cover up on the surface interval.
  • Solo is a fundamental risk (hypoxic blackout with no buddy). Any doubt = No-go.

Spearfishing in Lesbos (Mytilene): spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

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.

TL;DR

  • Lesbos is a split plan: sheltered Gera and Kalloni gulfs, or clearer open rock when wind allows.
  • In N/NE meltemi, move away from Molyvos and Petra toward Vatera, Agios Fokas or the gulfs.
  • May is fully closed in Greece; outside May, spearfish freediving-only with the 5 kg per person daily limit.

Where can you spearfish in Lesbos?

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.

Conditions and season essentials

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.

FAQ

Do you need a licence to spearfish in Lesbos?

No spearfishing licence has been issued in Greece since 2014. Check gov.gr before travel for the recreational-fisher registry.

Is spearfishing banned in May?

Yes. May is a total spearfishing ban across Greece, including Lesbos.

Where do you go in meltemi?

Use Vatera, Agios Fokas or the Gera and Kalloni gulfs when N/NE wind makes the north coast poor.

What fish are typical?

The gulfs suit tsipoura, lavraki and octopus; clearer open rock adds grouper, dentex and sargos.

Is scuba spearfishing allowed?

No. Spearfishing in Greece is freediving-only; scuba and compressed-air gear are banned.
