• ✓⚠️ MAY — a TOTAL spearfishing ban for the whole month, every year (ΠΔ 373/1985, art. 3§1α). This is law in force, not a draft.
• ✓No licence required (abolished 2014, Ν. 4256/2014). BUT Greece is rolling out a mandatory, FREE recreational-fisher registry (the ΟΣΠΑ state registry / Μητρώο Ερασιτεχνών Αλιέων, spearfishing included) — free until 31.12.2026. Check gov.gr before you travel.
• ✓Age: 16+ (under-16 spearfishing is forbidden; ΠΔ 373/85, art. 3§1γ).
• ✓Daytime only: sunrise to sunset. Night is forbidden (ΠΔ 373/85, art. 3§1β).
• ✓Freediving only: scuba/any air-supply apparatus is banned — it may not even be carried aboard (ΠΔ 373/85, art. 3§2γ).
• ✓Distances: ≥200 m from bathers, harbours, moored vessels and marked nets; no hunting in fairways or harbour entrances/exits (ΠΔ 373/85, art. 3§1δ/ε).

• ✓Invasives: taking the lionfish (λεοντόψαρο) is encouraged — ⚠️ venomous spines. The silver-cheeked toadfish (λαγοκέφαλος) ☠️ DO NOT EAT — deadly toxin (TTX), sale banned (EU 854/2004), it bites. The rabbitfish (γερμανός) is edible — venomous spines.
• ✓Do not touch antiquities (Ν. 3028/2002); diving is forbidden in declared underwater archaeological zones. Map of the zones — the ENALIA geoportal (thalchor-2.ypen.gov.gr/layers/geonode:ENALIA).
• ✓No-take zones: the national marine parks of Alonissos/N. Sporades and Zakynthos (Laganas) — spearfishing banned park-wide; the Southern Kynouria/Arcadia diving park (Ν. 4688/2020) — banned too. Check the no-take map.
• •Coming: two new national marine parks are being created (Ionian + South Cyclades, ~27,500 km²). NOT yet in force (ΠΔ under review, mid-2026). Once live — a trawl ban + a seasonal coastal closure 15.04–31.05; in the strict zones spearfishing will be banned. Check before the season.

• ⛔ Pinna nobilis (πίννα, fan mussel) — full ban on taking/killing (Habitats Dir. 92/43 Annex IV; critically endangered).
• ⛔ Corals and sponges — recreational taking PROHIBITED (ΠΔ 373/85, art. 1§6).
• ⛔ Mediterranean monk seal (Monachus monachus) — strictly protected, keep your distance.
• ⛔ Sea turtles (Caretta caretta, Chelonia mydas) — protected, taking/disturbing is PROHIBITED.
• ⛔ Seahorses (Hippocampus) — protected.

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).

• 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.
