The King Tides Project helps us visualize future sea levels by documenting today’s highest tides. Share your photos of Marin’s shoreline during King Tides or post them on social media (#kingtides) to help us create a record of how our shoreline is changing.

Mark your calendar: this winter's King Tides will occur on December 23-24, 2022 and January 20-22, 2023 when morning high tides tides are forecast to exceed 7 feet.

Check out the submitted photos gallery and remember to BE SAFE near high water!
