Go
“Go”: a rideable window long enough to count. “Marginal”: it might work, not for long enough to promise. “No wind”: nothing rideable today. “Not yet”: too far out, or the models still disagree. Drawn as an outline, never a colour. The small line underneath says where the number comes from: which models, whether they are corrected against wind measured at this spot, and whether what you see was measured or forecast.

Meltemi stays in your range from 09:00 to 20:00.

Hour by hour
Each bar is one hour's forecast, coloured by your range: solid inside it, amber just short or gusty, muted outside. On a day nothing reaches your range, nothing takes a colour: there is data, and it is honestly short. Gusty hours are demoted: when the jump between mean and gust is big, an in-range hour shows amber. Here the spread, not the average, decides the day.

Wind angle

Offshore

Blowing off the beach. It will carry you away from the shore. Do not go without cover.

Thermal build
Two questions, answered separately: is the thermal setting up (the label), and does it build far enough for your minimum (the fill)? It can honestly set up and still stop short; then the gauge turns amber and the sentence names the gap.

Local knowledge

The wind blows side-offshore from the left in all the bays: if gear fails, it pushes you out to sea. Stay inside your bay's limits, ride in front of a centre with a rescue boat, and never go further out than you can fight back upwind from.

In the island's lee the wind comes down gusty off the land: sudden, violent gusts near the shore, rotor at the bay edges, rocks at both ends. It gets stronger still the further out you go.

Afiartis is the flat southern tip of Karpathos, where the Meltemi, squeezed by the island's mountains, comes off the land at its hardest. Three bays in a row beside the airport serve the same wind at three levels: shallows for learning, an open bay for slalom, and the notorious Devil's Bay for the very strong. Speed world championships have been sailed here.

How good is this forecast±4.5 kn

Tuned on 464 measured sessions at this spot, average error 4.5 kn. The correction refits itself nightly. Averaged over every scored hour here, calm ones included. The per-wind rows on the full record are the numbers to plan a session on.

Full track record

Measured, never assumed: every forecast is frozen when published and scored against wind measured at this spot. The figure is the average error over recent measured sessions here, and no other spot's number is ever borrowed.

About this forecastModel ensemble · tuned on 464 measured sessions here · forecast, not measured

No openly available high-resolution weather model covers this spot (some commercial sites run private local models). The forecast runs on continental and global models, which resolve the coastline more coarsely; expect a wider margin than at a spot with a local model.

No live wind sensor here yet. The number above is forecast, not measured.
