Pipeline is a legendary reef break on Oahu's North Shore that produces some of the world's most powerful and hollow barrels. The wave stands up steeply on a shallow reef with a sharp take-off zone, creating intense hollow tubes that demand expert technique and split-second timing. This iconic spot is best in winter when North Pacific swells arrive with consistency, though it can turn dangerously shallow and fast during larger swells.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Pipeline is 0-1ft with a 7.45s swell period. Wind is ENE at 10mph and conditions are rated Very Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Pipeline is 0-1ft, produced by a 0.7ft SSW primary swell at 14s, a 0.6ft NW secondary swell at 9s, a 0.3ft SSW tertiary swell at 9s, a 3.1ft NE wind swell swell at 7s. Breaking wave height is the actual rideable wave size at the shore — calculated from offshore swell data using this spot's coastal bathymetry — not the raw buoy reading.
Based on the current 5-day forecast, the best window to surf Pipeline is Saturday from 8 AM to 11 AM with 2ft waves, a 7.9s swell period, and conditions rated Poor - Fair. Check the hourly forecast for updates as conditions can shift.
Pipeline works best with a N, NW swell and S, SE winds. Offshore winds groom the face of the wave, while onshore winds turn it sloppy. Cross-offshore conditions usually produce the cleanest shape.
Tide plays a big role at Pipeline. Mid tide works for most beach breaks, while reef and point breaks often prefer higher or lower stages. Use the tide chart above to line up your session with the swell peak.

The prime season at Pipeline is winter, when swell direction, wind patterns, and water temps line up most consistently. Outside the peak season you can still score, but you'll need to watch the forecast closely for the right windows.
Common hazards at Pipeline include shallow reef, strong currents, localism, rocks, extreme wave power. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our Pipeline forecast uses NOAA GFS and other weather models combined with spot-specific bathymetry to calculate breaking wave heights. Short-range (1-3 day) forecasts are most reliable. Extended forecasts show general trends. Visit /public/accuracy for per-spot and regional performance metrics.
