Although these strong  winds greatly reduce our visibility for spotting whales and their blows, it does serve a valuable purpose in the ocean.  According to NOAA Fisheries:

Upwelling can occur year-round off the northern and central California coast. The winds transport surface waters (upper 15 m) offshore, which are replaced by the upwelling of deep (100-125 m), cold (8°C), and nutrient-rich waters from the shelf break region. 

The upwelled water fuels high phytoplankton production and subsequent high biomass of copepods, euphausiids, and other zooplankton during the summer.
