Tides are heights in feet above mean lower low water (MLLW), the datum on NOAA's charts.
Currents are speeds in knots:
flood runs up the Bay,
ebb runs back out, and
slack is the pause in between. Times are Pacific time.
These are NOAA's
predictions, worked out from astronomy and long local records, not measurements. Wind, air pressure and river flow can change the real water, so do not rely on them alone for navigation or safety.
