What to expect
Daytime
Mild afternoons in Hanoi are the prize in December. You can eat outside on the good days. You still want something for the breeze.
This is walking weather. Shade is useful, not essential the way it is in the hot months. A long outdoor day is a reasonable plan.
Rain
December is on the drier side of the year in Hanoi. Showers are possible. They do not define the month.
A shell that lives in the bag is enough. This is not August, and it should not be packed as if it were.
Evening
Evenings are cooler. A layer helps after sunset.
What to pack
A layer for cooler evenings
