Athens weather in December

December in Athens brings mild but wet winter weather. Daytime temperatures average 14.1°C (57°F), while nights cool to 7.4°C (45°F). You'll see around 86mm of rainfall spread across 8 rainy days, so expect occasional showers. Despite the rain, Athens still enjoys 7.3 hours of sunshine daily, offering crisp, clear days between wet spells. The city rarely freezes, making it far gentler than northern European winters.

This is Athens' low season, with fewer tourists and a relaxed local atmosphere. The holiday spirit builds as Christmas decorations appear around Syntagma Square and Plaka. You'll find fewer crowds at major sites like the Acropolis and Parthenon, making for more peaceful exploration. Restaurants and cafes take on a cozy, intimate feel perfect for enjoying Greek coffee and warming meals.

December 2026 is ideal if you prefer quiet travel and lower prices. Pack layers and a waterproof jacket to handle rain showers. The mild temperatures mean you won't need heavy winter gear. Book accommodations early for holiday week (late December), as some travelers escape colder climates. Expect moderate crowds only around Christmas and New Year's Eve.
