Weather in Brussels in January

January in Brussels is a coat month. Treat it as cities, food and short walks, not as a terrace holiday.

In Belgium, this is how Brussels actually wears January, not how a country centroid would. January is the cold side of the year in Brussels. Pack for that, not for a leftover summer photo.

You want a proper coat in Brussels in January, 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.

Pack a shell you will actually carry. The monthly table is the place for totals. This is the feel: usable, interrupted.
