SAN FRANCISCO (KPIX) -- The King Tides that inundated low-lying areas around the bay on January 19th, 20th, and 21st also brought the reciprocal lowest tides possible, as shown in this timelapsed towercam video showing the water draining away from pier along the Embarcadero, from noon to 6 p.m.
Tides fluctuated a total of more than 9 feet around the Bay, and even more elsewhere as the regularly occurring tidal phenomenon peaked. The highest tide on January 20th was just before noon, with the lowest point occurring just after 6 p.m.
