What to expect
Daytime
Days in Slovenia in January are about getting between indoor places. The cold is the story. Gloves are not a fashion choice.
A clear spell is for a short walk, then back in. Do not plan a long outdoor day as the default. Night falls early and the cold deepens with it.
Rain
January is on the drier side of the year in Slovenia. Showers are possible. They do not define the month.
A shell that lives in the bag is enough. This is not September, and it should not be packed as if it were.
Evening
Evenings are cooler. A layer helps after sunset.
What to pack
Rain jacket
A layer for cooler evenings
