Spot Guide
The Klamath River mouth is a regional classic that can produce long, barreling rides of 150-300 meters when sandbars align with incoming NW swell. The constantly shifting sandbars from the river outflow create unpredictable but rewarding conditions for experienced surfers. However, the salmon runs attract seals, which attract great white sharks — multiple shark attacks have been documented here, making it one of the higher-risk spots on the California coast.
