Good to know
Which beaches in Mathraki are more sheltered from the wind?
It comes down to which way the coast faces. When the maistros blows, coves facing the other way have less open water in front of them for a wave to build across, so they are usually more comfortable. It is not a guarantee — the same beach changes character when the wind turns. Check live wind and waves before you go.
How is this list ordered?
By which beaches have the best conditions at that hour, so the order changes through the day: a beach that leads in the morning can drop down the list in the afternoon, once the wind picks up. When there is no live weather data, they are listed by how well known each one is — not by a score of ours.
