Where to Go in Greece in December
Northern Greece
Macedonia & Thrace, including Thessaloniki and Halkidiki
Late winter in December and continuing into February brings a final flux before spring: freezes overnight, some sunny days and occasional storms from the west that dump rain on the coast and snow inland. Ski areas around Vasilitsa and Parnassos remain reliable for winter sports, although hillside roads can be tricky after fresh snow. Plan indoor alternatives like winery or museum visits when low-pressure systems arrive, and travel with flexible plans in case of short closures.
Central Greece & Athens
Attica, Evia, Delphi, Parnassos
December’s short, cool days make Athens a city of cafés and museums, while nearby slopes open for winter sports when conditions allow. Holiday markets enliven central districts and the lower-altitude countryside still offers mild pockets for daytime wandering. Travelers should expect an unpredictable mix of sun, wind and rain - a versatile wardrobe and flexibility with transport are wise choices.
Peloponnese
Nafplio, Olympia, Mani, Taygetos
December’s weather is a mix of occasional storms and crisp, clear days; coastal towns are quiet but atmospheric, and inland valleys can see frosts overnight. Skiing is possible on higher slopes if there has been enough winter snowfall, but most travelers come for off-season tranquillity and local winter festivals. Bring warm clothes and be prepared for shortened daylight and the chance of wet weather on sightseeing days.
Ionian Islands
Corfu, Kefalonia, Zakynthos, Lefkada
December offers green winter landscapes and brisk, damp days; occasional Mediterranean storms can cause ferry delays but also clear the air for crisp, cool walks. Local Christmas and Epiphany traditions are observed in the islands’ towns, providing cultural experiences that differ from the summer scene. Pack warm waterproof layers and expect an authentic, low-key visit away from crowds.
Aegean Islands - Cyclades & Dodecanese
Mykonos, Santorini, Naxos, Rhodes, Kos
December sees mild days interspersed with storms that can make the Aegean moody and dramatic; snow is rare at sea level but can fall on higher inland hills of some islands. Holiday periods bring local festivals and a few seasonal events, but most island nightlife is muted compared with summer. Pack warm, waterproof layers and enjoy the islands’ calmer, more local character if you prefer to avoid crowds.
Crete
Chania, Heraklion, Agios Nikolaos, Samaria Gorge
December’s mild winter days alternate with rainy spells and cooler nights; while heavy snow is rare on the coasts, the White Mountains can have significant winter cover. Crete’s festive season is observed with local customs and fewer tourists, which suits travelers seeking an authentic off-season feel. Pack a warm midlayer for evenings and check inland road conditions if you plan mountain excursions.
