The president was set to attend a reelection campaign reception in Atherton on Tuesday evening.
On Wednesday morning, Biden plans to meet with the President's Council of Advisors on Science and Technology in San Francisco, which the White House describes as "the sole body of advisors from outside the federal government charged with making science, technology, and innovation policy recommendations to the President and the White House."
Biden has two more campaign receptions on Wednesday afternoon and evening before planning to depart via San Francisco International Airport to head to Arizona later in the day.
The president last visited the region in June for a three-day trip.
