Adjustments, Web sites help calculate high, low tides
I know from the newspaper San Francisco's high- or low-tide time and magnitude. How can I figure tides elsewhere e g Monterey or Ft Bragg?

There are specific relationships between key tide stations such as San Francisco, and secondary stations such as Fort Bragg and Monterey. Using these you need to know predicted high and low tides at the key or reference station and adjustment for time and height at the secondary site. Height adjustment is either a plus/minus difference in feet or a ratio where the reference station height is multiplied by a constant. Example, high tide this morning at the Golden Gate Bridge is 4.7 feet at 10:42 a.m. Adjustment for Monterey is minus .5 feet and minus 1 hour 8 minutes. That translates to 4.2 feet at 9:34 a m. Printed tide tables are usually available at marinas, harbors or wherever fishing equipment is sold. The data is also available at noaa.gov.
