9 active NOAA stations report within 150 km of Steamer Lane. The closest wave buoy is NDBC 46092 (MBM1), 22 km S of the break. Buoy 46012 sits upstream in the swell window, so it registers an incoming swell before it reaches the sand.
Stations are ranked by how much they tell you about Steamer Lane, not just by distance: a buoy sitting upstream — in the direction the swell comes from (about W here) — registers a new swell before it reaches the break, so it earns a lead time; a buoy behind an island is marked as shadowed; stale reports rank below fresh ones. Readings are the latest public NOAA observations and refresh hourly.
