Weather in Athens in December
Expect cool, fairly changeable weather in Athens in December, early winter. Daytime highs average around 15°C / 59°F, and nights drop to about 9°C / 47°F. There are typically 6 rainy days, with around 64 mm of rain in total. Sea temperatures average around 17°C / 63°F, too cold for most people to swim. Athens sits in a basin ringed by mountains, which traps heat in summer and keeps the city drier than much of Greece.

Bring a warm coat, layers, an umbrella and shoes that can cope with rain. Sunny spells between the rain can be beautiful, with clear air and long views. Plan outdoor time around the middle of the day, when it's at its warmest.
