The Old Point Loma Lighthouse is the highest point in the park and has been a San Diego icon since 1855. The lighthouse was closed in 1891, and the New Point Loma Lighthouse opened at a lower elevation, as fog and low clouds often obscured the light at its location 129 meters (422 feet) above sea level. The old lighthouse is now a museum, and ...
Point Loma (Spanish: Punta de la Loma, meaning "Hill Point"; Kumeyaay: Amat Kunyily, meaning "Black Earth") [1] is a seaside community in San Diego, California, United States. Geographically it is a hilly peninsula that is bordered on the west and south by the Pacific Ocean, the east by San Diego Bay and Old Town , and the north by the San ...
Tide tables, sometimes called tide charts, are used for tidal prediction and show the daily times and levels of high and low tides, usually for a particular location. [1] Tide heights at intermediate times (between high and low water) can be approximated by using the rule of twelfths or more accurately calculated by using a published tidal ...

Tidal range is the difference in height between high tide and low tide. Tides are the rise and fall of sea levels caused by gravitational forces exerted by the Moon and Sun, by Earth's rotation and by centrifugal force caused by Earth's progression around the Earth-Moon barycenter. Tidal range depends on time and location.
A chart datum is the water level surface serving as origin of depths displayed on a nautical chart and for reporting and predicting tide heights. A chart datum is generally derived from some tidal phase, in which case it is also known as a tidal datum. [1] Common chart datums are lowest astronomical tide (LAT) [1] and mean lower low water (MLLW).
