King Tides are Coming

Mother Nature’s early Christmas present will be a series of high tides (6.6’ feet or more) from Dec. 21 to Dec. 24. Even higher tides will come on January 20 and 21. Check the interactive tide chart on the right side of this page; by clicking on the Day + button, you can advance to these dates and see when these tides will reach their peak. Remember, rain and low-pressure fronts can increase the height of these king tides so avoid driving or parking in areas subject to flooding.

Snap the Shore, See the Future

The California King Tides Project helps people visualize how sea level rise will impact their lives. They invite you to document “King Tides,” the highest high tides of today, by taking and sharing photos of the shoreline. King Tides images offer a living record of the changes to our coast and a glimpse of what our daily tides may look like in the future as a result of sea level rise.

Grab your smartphone to help the California King Tides Project visualize sea level rise. Learn more on The King Tides Project website.

Attend King Tides Events

A number of educational outings are scheduled in Marin and San Francisco to discover what extreme high tides can tell us about sea level rise. Here are four to choose from:
