Santa Ana River Jetties is a dynamic rivermouth break where the Santa Ana River meets the Pacific, creating shifting sandbars and variable wave formations depending on river flow and swell conditions. The jetties themselves provide structure that helps organize swells and create more defined peaks, making it a fun option for intermediate surfers looking to escape some of the region's heavier breaks. Water quality can fluctuate based on river conditions, but when clean swells align with good river flow, this spot offers fun, approachable waves with solid walls.
Wave heights shown are breaking wave heights — the actual rideable wave size at this spot.
The current wave height at Santa Ana River Jetties is 3-4ft with a 17.75s swell period. Wind is SW at 7mph and conditions are rated Fair. The forecast updates hourly so you can plan your session around the cleanest windows.
