North Coast Sea Conditions
at a Glance

Base page and URLs to Navy W3 data last updated: Friday January 17, 2020 10:00 AM by JADELAARS.

This page was done by Chuck Tribolet, but all the data and pictures come from the National Oceanographic and Atmospheric Administration, Scripps Institution of Oceanography, and the U.S. Navy and is excerpted from http://cdip.ucsd.edu/ and https://www.fnmoc.navy.mil/ww3_cgi/index.html.  If you would like to learn more about how to read this information, see http://www.garlic.com/~triblet/swell/Inet1XMP.html and http://www.garlic.com/~triblet/swell/UPSSwell.pdf.

I also have a Monterey Sea Conditions at a Glance page, and Michael Owens maintains a Central Coast Sea Conditions at a Glance page.

You can click on any of the thumbnails to go directly to the full-size version of that image.

This information should be used to decide whether to go to the ocean.  Conditions sometimes change unexpectedly, so you should study the conditions in person and check the latest weather reports before deciding whether to get into the water.
 

CAVEAT EMPTOR: I don't dive the North Coast at all, so I have absolutely no way way of validating this.  So, PLEASE, use an extra dose of caution in using this data, AND let me know if I've missed the mark.
