Weather in Thessaloniki in December
Expect cold, often wet weather in Thessaloniki in December, early winter. Expect highs of about 10°C / 49°F and overnight lows near 3°C / 38°F. Nights are chilly, so bring something warm for the evenings. Sea temperatures average around 15°C / 59°F, too cold for most people to swim. Rain falls on around 7 days, with about 62 mm in total, usually in bursts rather than all-day drizzle. Thessaloniki sits on the Thermaic Gulf in northern Greece, with Mount Olympus visible across the water on clear days. Cold snaps from the north can bring frost, icy winds and a dusting of snow. Days bring around 9½ hours of daylight, so plan sightseeing for the middle of the day. Bring a warm winter coat, a hat, gloves and sturdy, waterproof footwear. Short days and changeable skies are part of the appeal, with fewer visitors and a more local feel. Plan outdoor time around the middle of the day, when it's at its warmest.
Swimming in Thessaloniki in December
At around 15°C / 60°F, the sea in Thessaloniki is too cold for most people to swim in December. Save swimming plans for July and August, when the water is much warmer. The city's own seafront isn't for swimming, so locals head to the beaches of Chalkidiki, about an hour away. There are no lifeguards or beach services out of season, so swim with care. A wetsuit makes a big difference if you want to get in.
