Overview

Winchester Bay South Jetty is a kitesurfing spot located at the mouth of the Umpqua River, on Oregon's south coast. The south jetty partially protects the riding area from dominant swells, creating slightly more sheltered conditions than open beaches. The spot offers access to both coastal waters and the estuary area. The sand dunes of the Oregon Dunes National Recreation Area extend to the south, offering a spectacular landscape.

On the water

Cold water year-round (10-14°C), 4/3 wetsuit minimum in summer, 5/3 in winter. Mix of ocean saltwater and fresh water from the Umpqua River. Very powerful currents at the river mouth, especially on outgoing tide. Waves of 1 to 2 meters on the ocean side, calmer conditions on the estuary side. Sandy bottom with shifting sandbars near the mouth.

Hazards

Extremely powerful currents at the Umpqua River mouth: the bar can be deadly. Never venture into the bar zone. Dangerous rock jetty if drifting: maintain safe distance. Sneaker waves on adjacent beaches. Shifting sandbars creating unpredictable breaking zones. Very cold water risking hypothermia. Maritime traffic of fishing boats entering and exiting the harbor.
