Please note: In many cases, the station position in our database is accurate
to only one minute. Thus, the tide gauge may not appear to be on the coast.

San Diego 823/081 RLR(1973) is 10.2m below BM14A(1942)
Documentation added 2011-08-24
Using NOAA data the RLR digram has been re-drawn. Primary benchmark is now 12 1926 6.325m above gauge datum. The previously used benchmark BM 14A official name BM 14 A RESET 1943 as appears on the NOAA website has a value of 5.148m above TGZ in the NOAA report of 3.6.1991 and 5.150m in the report of 21.4.2003. For information: data values for the early 1980's may look high in comparison. This could be due to the El Nino Southern Oscillation (ENSO) as it is mirrored along the Californian coast.
