King Tides in Redwood City, 12/14/20 by Ronald Horii
The King Tides are the highest tides of the year. There were King Tides on December 12/13-15/20. On 12/14, I went to Redwood City to see the effects of the King Tides on San Francisco Bay. I went to see them at Pacific Shores Center, the Port of Redwood City, Bair Island, and Redwood Shores. The time and peak height of the King Tide varies with location, but at the entrance to Redwood Creek, it was 9.1 feet at 11:31 am. King Tides also mean unusually low tides, but the minimum tides occur after dark. It was -1.5 feet at 6:51 pm at the same location. Other nearby locations were similar.
These pictures are shown in chronological order of the high tide shots. Each high tide shot is matched with a lower tide shot from approximately the same view. The low tide shots are picked to match the high tide shots and are not in chronological order. They are closer to being in reverse order.
What's important about the King Tides is that they may give us a glimpse into the future. Due to sea level rise, today's King Tide levels may be tomorrow's average tides or even low tides.

NOAA has a tool for visualizing the flooding that would be caused by various levels of sea level rise (assuming today's infrastructure). This shows how much will get inundated by 5-feet of rise, which is in the range of many models (see the last picture): https://coast.noaa.gov/slr/#/layer/slr/5/-13601297.555245275/4512012.901276003/13/satellite/none/0.8/2050/interHigh/midAccretion
