What to watch in the eastern North Pacific
The U.S. Pacific coast is dominated by long-period groundswell and strong seasonal upwelling that keeps nearshore water cold. Watch swell period as closely as wave height — a long-period west swell can make harbor entrances and bar crossings hazardous even when the wave height looks modest.
