San Francisco fog is local, not universal.
Conditions can differ sharply between the coast, City Hall, the Mission, and the other side of a hill. Build the plan around the actual neighborhood and a flexible visual idea rather than an app’s citywide icon.
The coast needs a wind plan.
Wind affects sound, temperature, clothing, hair, ceremony setup, and whether guests can stay comfortable. Choose a sheltered alternative and decide in advance what conditions would trigger it.
Redwoods get dark earlier than sunset.
Dense canopy reduces light and warmth well before the published sunset. Ceremony timing, flash, clothing, sound, and guest mobility matter more here than a generic golden-hour calculation.
Summer inland heat changes the human schedule.
North Bay and wine-country heat can make an exposed ceremony difficult even when the photographs would look bright. Shade, water, shorter portraits, and moving the ceremony later protect both people and images.
Rain needs one real alternative.
A covered ceremony, an indoor portrait location, umbrellas, towels, and slightly more travel time are usually enough. The goal is not to reproduce the dry-day plan under cover; it is to create a good day in the weather that arrived.
