What to expect
Daytime
Mild afternoons in San Francisco are the prize in July. 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
Rain is not the story in San Francisco in July. 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
