What to expect
Daytime
Cool days in Porto: a jumper you can take off, a shell in the bag. Walking is fine. Lingering outside without a layer is optimism.
Mornings and evenings are colder than the postcard. Pack for both, especially if you leave the built-up centre.
Rain
December is the wet side of the year in Porto. Days can be heavy. Plans that cannot survive rain are the wrong plans.
This is not a reason to skip Porto 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
Rain jacket
A layer for cooler evenings
