What to expect
Daytime
Days in United States 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
Rain is not the story in United States in January. Pack for sun. A shower would be news, not a plan.
Do not build the trip around weather windows. Build it around shade if it is hot, and around getting outside if it is not.
Evening
Evenings are cooler. A layer helps after sunset.
What to pack
A layer for cooler evenings
