How far in advance should I book the Rhodes to Symi ferry?

For July and August, book this route 3–6 weeks in advance. For May, June, September and October, 1–2 weeks is usually sufficient. Cabin berths on overnight ferries fill fastest — book as early as possible if you need a specific cabin class. Check the Teleporio Score before booking to identify the best departure window.

What happens if the Rhodes to Symi ferry is cancelled due to bad weather?

When a Greek ferry is cancelled due to weather, operators are required to offer a full refund or rebooking on the next available sailing. You are not entitled to compensation for consequential costs such as hotels or flights missed as a result. Always build a buffer day before any onward flight or transport connection when island-hopping in summer, particularly on routes exposed to the Meltemi wind.

What is the Beaufort scale and how does it affect the Rhodes to Symi crossing?

The Beaufort scale measures wind force from 0 (dead calm) to 12 (hurricane force). For Greek ferry travel, Beaufort 1–3 is ideal. Beaufort 4–5 means noticeable swell and possible motion sickness on smaller vessels. Beaufort 6–7 causes delays and cancellations on catamarans and hydrofoils. Beaufort 8 and above grounds most island ferry services completely. Teleporio’s Beaufort score factors current and forecast conditions into every route recommendation.

The Rhodes to Symi Crossing

high-speed catamaran operated primarily by Dodekanisos Seaways and Symi Visitor; passenger-only vessels carrying 80-150 passengers; the crossing from Mandraki harbour (Rhodes Town) to Gialos (Symi port) covers approximately 25 nautical miles

The crossing takes approximately 50-60 minutes on the fast catamaran; slower ferry services take up to 2 hours. 2-3 departures daily in summer (June-September); 1 daily in the shoulder season; reduced winter service; day-trip boats from Rhodes often use the same route with extended stops

Sea Conditions and Beaufort Exposure

the Rhodes-Symi channel passes through a series of straits between islands and the Turkish coast that provide significant shelter from the prevailing north-northwest Meltemi; the crossing is one of the more protected in the Dodecanese and is rarely cancelled below Beaufort 7; morning crossings in July-August are reliably smooth

some services stop at Panormitis Monastery on Symi's south coast before the main Gialos harbour — check your ticket for whether you want the monastery or the harbour stop

Booking and Tickets

tickets can be bought at the Mandraki port kiosks on the morning of travel in most conditions; in July-August, booking ahead is recommended as day-trip combinations fill quickly; online booking via Dodekanisos Seaways website

Arrival

arriving at Symi's Gialos harbour is one of the great Aegean arrival experiences — the neoclassical amphitheatre of painted mansions reveals itself fully as the boat enters the harbour; day-trippers from Rhodes should arrange the boat back before exploring as departure times are fixed; staying overnight gives a completely different, quieter experience of the island after day-trip boats depart in the afternoon
