Where to Swim Today.
A Beach Forecast.

The question asked every summer morning at Paralia Figia — where is the sea calm today? — answered by a page that checks the wind and ranks ten beaches around Marmari and Karystos.

Every beach in southern Evia answers to the wind differently. A southerly that churns up the water at Figia can leave Kallianou glassy, and a meltemi from the north does the opposite. Locals carry that map in their heads; this page writes it down and pairs it with the day's forecast.

Each beach carries three numbers from local knowledge: the wind direction that hits it head-on, how sheltered it is (0 to 1), and — for Great Sand and Zastani — an extra penalty for the northerly funnel the kite-surfers love. The daytime average wind (08:00–20:00) is scored against each beach: onshore wind counts in full, offshore barely at all, and shelter damps the rest. Lowest score wins.
