Expect winter layers, not mild afternoons

Milan in December suits travellers who do not mind keeping a coat on while exploring. The average afternoon is cold enough that a warm outer layer, jumper and closed shoes should be your starting point, with gloves and a scarf useful after dark. Colder nights can fall to -4°C or below, so do not judge your evening clothing by how it feels at lunchtime. Even a milder spell is not a reason to pack for warmth. Plan longer outdoor stretches around the middle of the day, then allow yourself somewhere indoors to warm up. If sitting outside comfortably is central to your holiday, December is a poor fit.

Work around short days and occasional rain

Rain is a consideration rather than a reason to rule the month out. There are about 7 rainy days, so a water-resistant coat and shoes that cope with wet pavements are sensible. Keep your plans flexible enough to move a longer walk when rain arrives, rather than expecting every day to be dry. Daylight is another constraint: with about 8.5 hours available, leaving outdoor plans until late afternoon gives you less room to manoeuvre. The limited sunshine also means you should not rely on the sun to make the cold feel comfortable. This month works best if you are content to mix outdoor time with regular indoor stops.
