Join Exploratorium and Port of San Francisco staff on the San Francisco waterfront to observe, photograph, and discuss the king tides. “King tide” is a popular, non-scientific term used to describe exceptionally high tides.

Come find out what causes the tides, why we have higher tides at this time of year, and learn more about the Waterfront Resilience Program's efforts to protect the city's waterfront. Because of sea level rise, the king tides of today provide opportunities to experience the “normal” high tides of tomorrow.

The high tide predicted at our closest tide station is 7.05 feet at 10:36 a.m.
