Coos Bay in Oregon offers a unique rivermouth break where the bay's outflow meets Pacific swells, creating shifty, sandbar-dependent peaks that can surprise even seasoned surfers. The spot faces ENE into the bay, meaning it picks up refracted and wrapped swell energy filtering in from the open Pacific, producing punchy, hollow sections when conditions align. The remote Oregon coast setting keeps crowds minimal, rewarding those willing to navigate the dynamic sandbars shaped by the bay's tidal currents.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Coos Bay is 4-6ft with a 8.95s swell period. Wind is NNE at 10mph and conditions are rated Fair. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Coos Bay is 4-6ft, produced by a 6.8ft NW primary swell at 9s, a 1ft SW secondary swell at 14s, a 0.4ft SW tertiary swell at 20s. 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 Coos Bay is Tuesday from 8 AM to 11 AM with 5ft waves, a 8.95s swell period, and conditions rated Fair. Check the hourly forecast for updates as conditions can shift.
Coos Bay works best with a W swell and E 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 Coos Bay. 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.

Common hazards at Coos Bay include strong currents, shifting sandbars, cold water, rip currents, heavy shipping traffic, unpredictable tidal flow. Always check conditions before paddling out, respect local etiquette, and never surf alone if you're unfamiliar with the break.
Our Coos Bay 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.
