Winchester Bay is a rivermouth break located on the Oregon coast where the Umpqua River meets the Pacific Ocean, offering sandbars that shift with river flow and tidal influence to produce punchy, hollow waves. The spot faces southeast toward the ocean, picking up Northwest swells that wrap around the river mouth and break over sand formations shaped by the river's outflow. This uncrowded gem rewards patient surfers with quality peaks, especially during fall when Oregon's swell season kicks in and offshore winds are most consistent.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Winchester Bay is 1ft with a 6.9s swell period. Wind is N at 9mph and conditions are rated Poor. The forecast updates hourly so you can plan your session around the cleanest windows.
The current breaking wave height at Winchester Bay is 1ft, produced by a 0.9ft SW primary swell at 12s, a 0.9ft WNW secondary swell at 11s, a 0.9ft WNW tertiary swell at 8s, a 3.6ft NW 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 Winchester Bay is Sunday from 6 AM to 9 AM with 5ft waves, a 9.65s swell period, and conditions rated Fair. Check the hourly forecast for updates as conditions can shift.
Winchester Bay works best with a NW swell and NE 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 Winchester 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.
