Sylvia,

Golden Gate Audubon hosts a digital version of "Birds of Northern
California" which has useful bar-graphs showing expected arrival and
departure dates.

http://goldengateaudubon.org/wp-content/uploads/PDFs/BirdsNorthernCalifornia.pdf

The graph on page 58 shows Swainson's Thrush to be common through early
September becoming uncommon through the end of the month and rare through
mid-October.

This chart....

http://www.marinaudubon.org/birds-arrival-departure.php

indicates the species departs Marin County in mid-October.
