Note, The blanks for the years 1940-41 are due to the Second World War. Apparently during that time, data was not collected by a lightkeeper.

Original data was sent by the Lightkeepers and now by the Marine Protected Area Guardian of Race Rocks to the Institute of Ocean Sciences where it is compiled and displayed at
