Weather in Heraklion in December
December is early winter in Heraklion: mild and one of the wettest times of year. Expect highs of about 17°C / 63°F and overnight lows near 10°C / 51°F. Sea temperatures average around 18°C / 64°F, refreshing for some, but too cool for most. Rain falls on around 10 days, with about 91 mm in total, usually in bursts rather than all-day drizzle. Snow often caps the high mountains, while the coast stays mild, with rain arriving in bursts from passing storms. Heraklion faces north across the Cretan Sea, with the mountains of central Crete rising behind the city. Days bring around 10 hours of daylight, so plan sightseeing for the middle of the day. Pack layers, including a warm sweater for the evenings and a light waterproof jacket. Weather can change quickly at this time of year, so check the forecast before a long day out. Plan outdoor time around the middle of the day, when it's at its warmest.
Swimming in Heraklion in December
Swimming in Heraklion in December is possible but bracing, with the sea at around 18°C / 64°F. For warm-water swimming, aim for July, August and September, when the sea is at its best. Try Amoudara, just west of the city, for clear water. There are no lifeguards or beach services out of season, so swim with care. If you feel the cold, a wetsuit top makes a difference.
Crowds & Prices in Heraklion in December
December is one of the quietest months in Heraklion, with few visitors and a local, everyday feel. It's the cheapest time to visit, with the best deals on accommodation. Christmas and New Year bring some Greek visitors home, but it stays quiet. With so few visitors, the atmosphere is genuinely local, and people have time to chat. Last-minute bookings are rarely a problem.
What's Open in Heraklion in December
Ferries to Heraklion from Piraeus run all year, but less often in December, and rough seas can cancel sailings. Direct international flights run mainly from spring to autumn, while flights from Athens operate all year. Life goes on in the main town, but most resort hotels and beach tavernas close until spring. Museums and archaeological sites are open on winter hours. Most sites close on 25 and 26 December.
Festivals & Holidays in Heraklion in December
Christmas is celebrated with church services, carols sung door to door by children and festive sweets like melomakarona and kourabiedes. On 6 December, Saint Nicholas, patron saint of sailors, is honored in harbors across Greece, and decorated boats appear alongside Christmas trees. In Heraklion, as across Greece, these traditions are very much alive. Otherwise, life follows its normal rhythm, with Sunday lunches and busy cafés rather than big events.
Is December a Good Time to Visit Heraklion?
It depends on what you want. In December, Heraklion is peaceful and inexpensive, but the season is over, the sea is too cool for most swimmers and the weather can turn. Expect highs of around 17°C / 63°F, lows near 10°C / 51°F and rain on around 10 days. It's fine for a quiet break or visiting Knossos. For a proper beach holiday, go in June, September or October.
