Can you swim in Greece in January?

The short answer

The sea around Greece averages 16°C in January. It is swimmable but bracing. Confident swimmers and acclimatised locals will be fine; visitors used to bath-warm summer seas may prefer short dips.

Live conditions matter most

Monthly averages set expectations, but a specific beach today depends on wind, waves and local currents. Use the live map or any beach page to see right-now temperatures.
