What NOAA buoy TCNW1 measures

As a NOAA meteorological station, TCNW1 reports wind speed, gusts and direction, barometric pressure, air and water temperature, and — where wave sensors are fitted — significant wave height, swell period, and wave direction.

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.
