What to expect
Daytime
You want a proper coat in Thessaloniki in December, not a festival jacket. Wind makes the same afternoon feel sharper than the map suggests.
Outdoor time is the middle of the day. Finish plans before the light goes. Evenings are for indoors.
Rain
December is the wet side of the year in Thessaloniki, the wettest stretch on these averages. Days can be heavy. Plans that cannot survive rain are the wrong plans.
This is not a reason to skip Thessaloniki if you like the place. It is a reason to pack for weather and to stop treating every grey hour as a failed holiday.
Evening
Evenings are cooler. A layer helps after sunset.
What to pack
