East Superior Spotter

NDBC station 45213 (East Superior Spotter) is a moored standard meteorological station at 47.585°N 86.585°W, operated by Michigan Technological University. 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; and full spectral wave-energy density, which separates overlapping swell trains by period and direction.
