Golden Gate. The Golden Gate is a strait on the west coast of North America that connects San Francisco Bay to the Pacific Ocean.
It is defined by the headlands of the San Francisco Peninsula and the Marin Peninsula, and, since 1937, has been spanned by the Golden Gate Bridge. The entire shoreline and adjacent waters throughout the strait are managed by the Golden Gate National Recreation Area.
During the last Ice Age, when sea level was several hundred feet lower, the waters of the glacier-fed Sacramento River and the San Joaquin River scoured a deep channel through the bedrock on their way to the ocean. The strait is well known today for its depth and powerful tidal currents from the Pacific Ocean.
Many small whirlpools and eddies can form in its waters. With its strong currents, rocky reefs and fog, the Golden Gate is the site of over 100 shipwrecks.
The Golden Gate is often shrouded in fog, especially during the summer. Heat generated in the California Central Valley causes air there to rise, creating a low pressure area that pulls in cool, moist air from over the Pacific Ocean. The Golden Gate forms the largest break in the hills of the California Coast Range, allowing a persistent, dense stream of fog to enter the bay there. Although there is no weather station on Golden Gate proper, the area has a mediterranean climate with very narrow temperature fluctuations, cool summers and mild
