North Point, Pohnpei, Micronesia (178)

NDBC station 52213 (North Point, Pohnpei, Micronesia) is a platform - special marine observation station at 7.081°N 158.244°E, operated by Pacific Islands Ocean Observing System. 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 ocean-current profiles through the water column.

PierMonkey uses buoy 52213 as the observation source for the surf forecast at P-Pass (Palikir), about 16 km away. Swell that registers here shows up at the break shortly afterwards, which is what makes this station worth watching.
