From the north, Point Arena receives freshwater from the Columbia River outlet. This low salinity water is pushed past Point Arena by the california current. The continental shelf is also variable, with numerous underwater caves, providing diverse habitat for fishes and upwelling. Strong persistant winds, along with the shelf topography, create extensive upwelling, providing feeding habitat for seabirds. The waters in this IBA also have extensive kelp forests, providing more fish diversity. The weather is characterized by cool, wet winters and dry summers.
