San Pedro South, CA (213)

NDBC station 46253 (San Pedro South, CA) is a moored standard meteorological station at 33.576°N 118.181°W, operated by SCRIPPS. PierMonkey reads its observations straight from the NOAA National Data Buoy Center and republishes them free, with no account required to see current conditions.

It reports significant wave height, dominant and average wave period, wind speed, gusts and direction, air and sea-surface temperature, and barometric pressure; full spectral wave-energy density, which separates overlapping swell trains by period and direction; and tide predictions from the nearest NOAA CO-OPS station.

A 16-day wave and wind forecast from the NOAA GFS-Wave model is available for this location alongside the live readings, so you can see both what the buoy is measuring now and what is expected to arrive.

PierMonkey uses buoy 46253 as the observation source for the surf forecast at Huntington Beach, about 19 km away. Swell that registers here shows up at the break shortly afterwards, which is what makes this station worth watching.
