Notice: Due to storm activity during the winter months, significant sediment deposits have been observed near the San Francisco water level station. This is impacting real-time water level observations, especially during low tide where observed water levels have generally been higher than astronomical tide predictions. The exact spatial extent of these sediment deposits and their influence on water levels away from the station is unclear. Please use caution when utilizing these water level data for marine navigation in this region.
