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.

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.

Law

  • 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 Sithonia: spots, seasons and rules

Updated 2026-07-09 · By Oleksandr, spearfisher

Spearfishing in Sithonia starts with choosing the side of the peninsula. The west coast on Toroneos, with Kelyfos and Porto Koufo, is the meltemi-sheltered side; the east coast around Sarti, Kalamitsi and Armenistis faces open Singitic water and Athos, so it is clearer but more exposed to N/NE wind and Aegean swell. Porto Koufo is the enclosed refuge. Greek national law then sets the boundary: May is unavailable, the licence system has issued no new spearfishing permits since 2014, the method is freediving, and the daily bag is 5 kg.

TL;DR

  • Sithonia splits west and east: Toroneos and Porto Koufo are the meltemi lee, while the Singitic side is clearer but exposed.
  • Listed spots include Porto Koufo Wall, Kelyfos, Bahia Beach Reef, Akti Kalogrias, Armenistis and Kalamitsi / Nemesis Wall.
  • Sithonia's June to October season starts after the Greek May stop, a full-month closure under ΠΔ 373/1985.
  • No new spearfishing licence is issued after the 2014 change; hunt on breath-hold only, stay within 5 kg/day, and keep Epinephelus grouper to 1/day.

Where can you spearfish in Sithonia?

The Sithonia registry entries describe terrain and exposure, not safety ratings. North wind points you west toward Toroneos and Porto Koufo. The eastern coast is often clearer, but it takes N/NE meltemi and Aegean swell, with dawn and lee windows in the local notes.

SpotTypeDepthLevelAccessNotes
Porto Koufo WallNatural harbour with outer capes and cavesShallow inside, steep wall outside-Boat or shoreListed as Greece's deepest natural harbour and a fully enclosed lee. The description mentions big snappers and grouper outside.
Kelyfos (Turtle island)Islet with steep reef and wallSteep change from shallow to deep water-BoatA Toroneos islet sheltered in the west-side meltemi pattern. The source lists coral, moray, octopus and grouper.
ArmenistisEastern reef with an underwater tunnelDeep reef with tunnel and separate spots-ShoreClearer but exposed to meltemi and north swell. The local notes says dawn is better.

How is the water visibility in Sithonia today?

The Sithonia facts do not include a live visibility feed. They place the clearest water on the east side toward Singitic Gulf and Athos, while the west coast is the meltemi shelter. The Neos Marmaras camera helps with surface water only.

What fish can you spearfish in Sithonia, Halkidiki?

The Sithonia profile names grouper, dentex, amberjack and lobster; spot descriptions also mention octopus, moray and snappers. Legal sizes include gilthead 20 cm, seabass 25 cm, white seabream 23 cm, grouper 45 cm and octopus 750 g. Dentex and amberjack use the general 150 g minimum. Grouper is capped at 1/day.

When is the best time to spearfish in Halkidiki?

For Sithonia, the local notes gives June to October. The practical choice is wind side: north pushes you west toward Toroneos, while a calm dawn can make the east coast clearer. May sits before that window and is legally closed for spearfishing throughout Greece.

Do you need a license to spearfish in Greece?

For Sithonia, do the paperwork check at national level. The old licence is not required, and after 2014 Greece stopped issuing new spearfishing licences. The free ΟΣΠΑ recreational-fisher registry is being rolled out until 31.12.2026, so check gov.gr. In the water, the rule is breath-hold only; scuba or any air-supply apparatus is banned even aboard. Daily catch is limited to 5 kg, or one heavier trophy, and grouper in the Epinephelus group is limited to 1/day.

FAQ

Where can you spearfish in Sithonia?

West-side names include Porto Koufo Wall, Kelyfos, Bahia Beach Reef and Akti Kalogrias. East-side names include Armenistis and Kalamitsi / Nemesis Wall, but that side is more exposed to meltemi and north swell.

Do you need a license to spearfish in Greece?

No old licence is required for Sithonia. Greece stopped issuing new spearfishing licences after 2014, but gov.gr should still be checked for the ΟΣΠΑ recreational-fisher registry.

Is spearfishing banned in May in Greece?

Yes. The Halkidiki season cannot use May, because ΠΔ 373/1985 closes spearfishing in Greece for that entire month every year.

What is the daily catch limit for spearfishing in Greece?

Count 5 kg/day as the Greek limit. One larger trophy can be retained instead, and Epinephelus grouper has a separate ceiling of 1 fish per day.

Is scuba spearfishing allowed in Greece?

No. Sithonia spearfishing must be done on breath-hold; scuba or other air supply is not allowed for the hunt or as gear kept aboard.
