Beaufort Scale Guide for Greek Ferries

Understand Beaufort 0–10 for Greek island ferries. Track Meltemi winds, plan safer Aegean crossings and find hotels before the weather changes your plans.

The Number That Runs Greek Ferry Travel

Imagine you have booked a high-speed catamaran from Santorini to Mykonos for 14:00 on August 12th. You checked the schedule. You bought the ticket. You packed light. But you did not check the Beaufort. By 11:00 the harbour is white-capped. By 13:30 the port authority has suspended high-speed services. Your crossing is not running.

This scenario plays out across the Aegean thousands of times every August. It is not bad luck. It is the Meltemi wind doing exactly what the Beaufort scale predicted it would do — at exactly the time of day it always does it. The Beaufort scale is the difference between a traveller who arrives and a traveller who waits.

What Each Number Means at the Jetty

Read a Beaufort value as an indication of wind force, not as a fixed comfort score or service decision. The same reading can accompany different sea states depending on wind direction, swell, location and route. Check the selected sailing with the current forecast and operator or port notice.

Strong wind warning: Rough conditions can lead to delay, cancellation or port restrictions, but there is no single Beaufort threshold that applies to every route. Check the selected operator and relevant port authority before travelling, and keep a flexible plan if a connection is time-sensitive.

The Meltemi — Predictable, Not Unavoidable

The Meltemi is a seasonal northerly wind of the Aegean. Its timing, strength and local effects vary by year, location and date; it is useful forecast context, not a timetable or operating rule.

This pattern is useful for planning but not a rule. On some Meltemi-exposed routes, an earlier departure may face less wind than a later one; the difference depends on the route, vessel and date. The same Santorini-to-Mykonos crossing can have different outcomes at 07:00 and 14:00, so Teleporio scores the specific departure time and still directs travellers to the operator for live status.

How Beaufort Feeds the Teleporio Score

Vessel type is one factor in crossing comfort, but a score or generic wind threshold cannot establish whether a particular service will operate. Check the current route forecast and operator or port-authority notice for each sailing; weather and operating decisions vary by route and date.

On the same island connection, vessel type, departure port and local conditions can change the available options. Check the forecast and current operator notice for the selected sailing; a general Beaufort threshold or vessel category does not guarantee whether a service will run.

Beaufort scale in Greece: a ferry-planning reference

The Beaufort scale describes wind force; it does not confirm whether a Greek ferry will sail. Use the forecast for context, then check the selected operator and port notice for current service status.
