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.
