State Line

State Line is an exposed beach break on the Oregon–California border near the mouth of the Winchuck River. It’s described as having fairly consistent surf, with the best conditions typically at mid tide. The bottom is primarily sand but includes rocks near the river mouth, and the area can feel remote. Water temperatures are very cold year-round (around 10–14°C, with winter months often closer to 11–13°C), so expect to need substantial thermal protection. A spring wetsuit setup is specifically recommended, including a hood, gloves, and boots, and the spot is also associated with colder-water gear needs. Safety-wise, the main concerns called out for this spot are rocks and sharks, along with rip currents and river mouth outflow currents. After heavy rain, it’s advised to check for logs and debris near the river mouth. Rescue/lifeguard coverage is described as none at the beach, so partner-surfing is recommended given the remoteness. From a wave-and-wind perspective, surf performance is described as average overall, with mixed wave shape and moderate power. East winds are reported to help by providing cleaner/offshore conditions, while West and Northwest winds can make things messier (onshore/cross effects). On larger swells, the break may close out.
