High Tides Are Back This November 2023

Sausalito - Mill Valley Bike Path Flooded

Living near the ocean we get to enjoy the many things that it has to offer, but we also have to deal with the issues it can bring. One of these issues are the occasionally higher than normal tides, sometimes referred to as “King” Tides. However, as opposed to other natural issues, we know when these high tides will occur far in advance. Based on tide predictions published by the National Oceanic and Atmospheric Administration(NOAA), tides levels that could be high enough to cause roadway flooding in parts of Marin, primarily coastal areas, are expected November 24-28, December 11-15 and 23-27, and January 9-13. If a high tide coincides with a significant storm, a tidal surge can occur, causing higher than predicted water levels.

The following list shows predicted high tides at or above 6.4 feet (rounded up to the nearest tenth) from October 2023 through January 2024 at the NOAA San Francisco tide gauge.


  • Nov 24, 8:41 AM, 6.4 feet
  • Nov 25, 9:16 AM, 6.6 feet
  • Nov 26, 9:52 AM, 6.7 feet
  • Nov 27, 10:28 AM, 6.7 feet
  • Nov 28, 11:05 AM, 6.5 feet
  • Dec 11, 9:24 AM, 6.4 feet
  • Dec 12, 10:01 AM, 6.6 feet
  • Dec 13, 10:42 AM, 6.7 feet
  • Dec 14, 11:26 AM, 6.6 feet
  • Dec 15, 12:14 PM, 6.5 feet
  • Dec 23, 8:05 AM, 6.6 feet
  • Dec 24, 8:46 AM, 6.7 feet
  • Dec 25, 9:26 AM, 6.7 feet
  • Dec 26, 10:07 AM, 6.6 feet
  • Dec 27, 10:46 AM, 6.4 feet


  • Jan 9, 08:55 AM, 6.6 feet
  • Jan 10, 09:42 AM, 6.8 feet
  • Jan 11, 10:30 AM, 6.9 feet
  • Jan 12, 11:19 AM, 6.9 feet
  • Jan 13, 12:10 PM, 6.6 feet

Some Tips to Prepare for Flooding:

● Move vehicles to higher ground, especially in flood-prone areas.

● Move items stored in low-lying areas, such as basements or other areas that have flooded in the past.

● Driving through flooded roads is dangerous!

Southern Marin Fire Department strongly encourages residents in low-lying areas to prepare for all upcoming high tide events.
