Buoys near Pipeline

6 active NOAA stations report within 150 km of Pipeline. The closest wave buoy is NDBC 51201 (Waimea Bay, HI), 7 km W of the break and upstream of it in the swell window.

Stations are ranked by how much they tell you about Pipeline, not just by distance: a buoy sitting upstream — in the direction the swell comes from (about NW 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.

Lead times use deep-water group velocity (Cg = gT/4π ≈ 2.8 km/h per second of period) projected along the swell direction, at this break's typical period; a buoy under 40 km away reads the same swell the break is receiving. Upstream = within 30° of the swell direction; shadowing is curated per break. Observations: NOAA National Data Buoy Center. Ratings: NOAA GFS-Wave, PierMonkey Rating v3.
