Central Cyclades

Greece — Cyclades

Greece

The Cyclades are a ring of roughly 220 islands (about two dozen inhabited) in the central Aegean, arranged around sacred Delos, with Syros's Ermoupoli as the regional capital and Naxos the largest island. For sailors this is the most dramatic cruising ground in Greece: whitewashed Choras above deep anchorages, volcanic coastlines at Milos and Santorini, sand-and-turquoise bays in the Small Cyclades, and short 10-30 nm hops between islands. The defining factor is the meltemi, the north wind that blows from about June to September and peaks in July and August, often at 20-30 knots and sometimes stronger. It makes the Cyclades a superb downwind and reaching ground but punishing to windward, so routes are planned south early and back north in early-morning legs, and every overnight stop is chosen by its shelter from the north. Most charters leave from Lavrio or Alimos (Athens) or from island bases on Syros and Paros. Harbours are a mix of town quays (stern-to, Mediterranean mooring, often free or cheap but crowded and ferry-washed) and a few true marinas; anchoring in sand is the norm everywhere else. This area file covers the islands in 12 subregions from the Attica gateway to Santorini and Anafi.

When to go

Main season May to October. May-June and September-early October are the sweet spot: warm water, fewer crowds and meltemi episodes that are usually shorter and weaker. July-August bring the strongest and longest meltemi (often Force 5-7 by day, sometimes more) plus peak crowds and prices; many advisers send less experienced crews to Kea, Kythnos and Syros from Lavrio in high summer rather than Mykonos, Naxos or Santorini, or to the Saronic Gulf or Ionian instead. Winter (Nov-Mar) sailing is possible but marked by gales from both north and south, reduced ferry and taverna service, and many harbours with little shelter from southerlies.

Weather and hazards

Meltemi (etesian wind): a dry N-NE wind (more NW in the south Cyclades) driven by high pressure over the Balkans and the heat low over Anatolia. Season mainly June-September, peaking July-August; typically builds late morning to early afternoon, often to Force 5-7 (17-33 kn), and may ease at sunset but can blow through the night and persist several days (sometimes up to about ten). Steep short seas build quickly — over 3 m within hours of a 30-kn blow across long fetches. Acceleration zones: the Kafireas (Kavo Doro) strait between Evia and Andros, the Andros-Tinos and Mykonos-Tinos channels, the Paros-Naxos channel, north of Amorgos, and sometimes south of Kea and Kythnos. Katabatic fall winds ('downslope gusts') hit lee anchorages hard under high ground: Kea, Andros, Tinos, Serifos (Livadi), Sifnos (Kamares, Vathy), Folegandros, Amorgos and Ios. Warning signs 24-36 hours ahead: rising pressure over the Balkans/northern Aegean, sudden drop in humidity (no dew on deck), altocumulus and very sharp visibility, and orographic cloud caps on island peaks. Tactics: go south early in the week, leave at dawn for any windward leg, plan 1-2 weather days, anchor on south- and southwest-facing coasts and lay out plenty of chain. Other hazards: heavy ferry and high-speed-craft wash in Paros, Mykonos, Naxos, Milos, Kea and Tinos harbours (keep clear of ferry berths and their laid anchor lines); crowded town quays in July-August with crossed anchors; deep water close inshore (Santorini caldera depths are hundreds of metres — use moorings); unlit or poorly charted rocks on some approaches (do not enter Gavrio, Andros, at night); summer thunderstorms and occasional southerly gales (sirocco) in spring and autumn when north-facing harbours become the safe ones.

Hurricane season

No tropical cyclone season. Rare Mediterranean 'medicanes' (tropical-like cyclones) mostly form in autumn and winter; the main seasonal wind risk is the summer meltemi plus autumn-winter gales and southerly sirocco blows.

Entry and clearance

Greece is EU and Schengen. EU-flagged, EU-VAT-paid yachts arriving from another Schengen/EU country generally have no customs clearance, but practice varies and some Port Police (Limeniko) offices still ask yachts to report on arrival with registration, insurance, crew list, passports and the eTEPAI receipt. Non-EU yachts (and EU yachts unable to prove VAT-paid status) need a Greek Transit Log: since 2024 it is applied for online through the myAADE portal (Applications > Customs Services > Transit Log) before arrival; boats with EU VAT-paid 'Union Goods' status receive an unlimited-duration log, others an 18-month log with continued check-in/out at controlled ports. Cruisers reported in 2025 being fined (€300 in one report) for not applying online before arriving, though Customs can still issue one if the system fails. Non-EU crew must enter at a port with passport control and observe the Schengen 90/180-day rule. In the Cyclades area, Lavrio is the usual first stop from the mainland, with Port Police and Customs offices reported at Olympic Marine (verify current status); for a definitive list of current ports of entry, check Noonsite's Greece formalities pages or a Greek yacht agent. Charter yachts' paperwork is handled by the charter base. Report to the Port Police in each port where they ask; in larger harbours (Syros, Paros, Mykonos, Naxos, Milos) expect them to check papers.

Permits and fees

TEPAI (cruising tax): payable by private and professional pleasure vessels over 7 m in Greek waters, paid online via the AADE eTEPAI service before or on arrival, per calendar month (minimum one month). AADE rates: over 7 m to 8 m €16/month; over 8 m to 10 m €25; over 10 m to 12 m €33; above 12 m €8 per metre per month (verify current rates on aade.gr). Discounts exist for professional vessels; boats hauled out or declared out of use are exempt for those months. Transit Log: online application via myAADE (a €29.50 fee was quoted in a 2025 cruiser report — verify locally). Harbour dues: many Cyclades town quays charge modest municipal fees collected by the port fund, often with separate water and electricity cards (about €10 a night cited in a 2026 Lavrio-Kos report); marina rates quoted by cruisers in 2026 ranged from free to about €110 a night — verify locally. Mykonos's new marina requires online booking. Delos: day visits only (archaeological site ticket required ashore), no overnight anchoring. Keros: protected archaeological island, landing prohibited. Bareboat charter: skippers need a recognised licence (ICC, RYA Day Skipper or equivalent) and charter companies generally require a second crew member with sailing experience; VHF certificate requirements vary by company.

Tides and currents

Tides are negligible: Aegean tidal range rarely exceeds about 10 cm, so depths on charts can be used at face value (watch barometric/wind setup of a few tens of centimetres). Currents are mostly wind-driven: during strong meltemi, surface currents run S-SW through the channels and reach several knots in the Kafireas strait between Evia and Andros (up to 5 kn reported). Sources: HCMR Mediterranean Marine Science paper on Aegean tides; Hellenic Navy Hydrographic Service (HNHS) charts and tide tables; CruisersWiki NE Aegean notes.

Money

Euro (EUR). Cards widely accepted in towns and marinas; carry cash for small-island tavernas, harbour dues and water/electricity at remote quays. ATMs in island main ports (fewer on the Small Cyclades, Anafi, Sikinos, Donoussa).

Radio and phones

Emergencies: Hellenic Coast Guard 108 (sea emergencies) or 112 (EU general emergency); VHF 16 for distress. Port Police / port authorities: VHF 12 (Ermoupoli port listens on 12). Hellenic Coast Guard HQ channel 07. Olympia Radio (Greek coast radio): VHF 16 calling; weather and sea bulletins in Greek and English on working channels — the Syros station broadcasts on VHF 04 for the Cyclades (verify schedule). NAVTEX 518 kHz: Iraklio (station I, covers Central and South Aegean, Saronikos and Kafireas strait) and Limnos (L). Forecasts: Hellenic National Meteorological Service (emy.gr, 'Greek seas'), HCMR Poseidon system, plus the usual GRIB models. Marinas: Olympic Marine VHF 09 (per Noonsite listing). Mobile coverage is good across the main islands (Greek 4G/5G networks; EU roaming applies), patchy in some remote bays (e.g. Kalotyri, Amorgos).
