Here's how the next 5 days are shaping up at Coos Bay, Oregon. Each day is rated based on breaking wave height, swell period, and wind — updated hourly from the latest NOAA GFS run.
Wed, Jun 24: 1–2ft, 7s period, rated Poor. Hold off if you can — morning starts out poor with 1-2ft waves. Later in the day looks more promising — 1-2ft and poor - fair.
Thu, Jun 25: 1–1ft, 17s period, rated Poor. Slim pickings today — 1-2ft and poor with gentle NNE breeze.
Fri, Jun 26: 1–1ft, 17s period, rated Very Poor. A slow one — 0-1ft waves and very poor conditions with 12mph SW winds.
Sat, Jun 27: 4–5ft, 15s period, rated Fair. Rideable all day with 3-4ft waves on WNW swell at 9s and gentle WSW breeze.
Sun, Jun 28: 5–6ft, 10s period, rated Fair. Dawn patrol is the move — 5-6ft on WNW swell at 10s with light SSE winds. The NW wind kicks in by afternoon — 9mph and poor - fair by then.
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 1-2ft with a 6.95s swell period. Wind is N at 9mph and conditions are rated Poor - Fair. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Coos Bay is 1-2ft, produced by a 3.7ft NW primary swell at 7s, a 1ft SW secondary swell at 13s, a 0.9ft SW tertiary swell at 15s. 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 Sunday from 6 AM to 9 AM with 5ft waves, a 9.6s 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.

The prime season at Coos Bay is fall, 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 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.
