Every beach
Beaches on Kasos
5 beaches mapped. The most sheltered first, then every other beach with a name; each one opens its own page.
Which side of Kasos is calmest in a north wind?
In a strong north wind the beaches of Kasos facing south and south-east stay calmest: Chochliákia, Helatros, and Mikro Avlaki beach. Beaches facing north are exposed to it.
How do you know which beaches are calm?
For every beach we measured how much open sea lies in each of 16 compass directions, using OpenStreetMap coastlines. Waves build over open water, so a beach with land close by in the direction the wind comes from is sheltered. Today's wind forecast from MET Norway is then applied, and the result is refreshed every 2 hours.
Are the forecasts reliable?
They are estimates. The model does not include swell from distant storms, and local gusts can be stronger than forecast. Always follow lifeguard flags and local warnings.
Which wind direction matters on Kasos?
The direction more than the strength. A beach is rough when the wind blows from the open sea towards it and calm when land lies upwind, so on a windy day one side of Kasos can be flat while the other has waves. That is why this page lists the calmest and roughest beaches for each wind direction, and the live ranking above applies today's forecast.
