In Greece, the month of December tends to be a bit chilly but more sunny than snowy (with the exception of the mountains) so it doesn’t have the natural “Christmassy” vibe of Europe’s many snow-covered cities. If you’re in a milder climate (like Athens) you might find it difficult to get your Christmas hat on even if all the shop-vitrines are decorated, clove and cinnamon smell is in the air and Christmas music is playing non-stop everywhere.
