About this spot

About

Ataka is a low-profile surf spot at the rivermouth near the harbour of Komatsu, with a sandy bottom and a breakwater/jetty setup that shapes the waves into left/right peaks. The spot is described as working on all tides, with wave quality rated good and a “fun” feel rather than purely technical conditions. For swell, it typically starts producing around roughly 1.0–1.5 m and can hold up to about 2 m or more before closing out. Optimal swell direction is described as NorthWest and West. One key wind note is that Southeast winds tend to be most favorable for offshore/cleaner conditions, while West/Northwest winds are more likely to turn onshore and make the water choppy. Conditions near the rivermouth require extra caution. Sources highlight strong currents, particularly after rainfall or during high swell, and mention tetrapods/submerged harbour structures. After heavy rain, pollution or debris is also noted, so it’s advised to avoid getting in immediately following heavy rainfall due to river discharge. Access is straightforward by car, with instant walking access from the harbour-rivermouth area. Crowds are generally quiet on weekdays with only a few surfers on weekends, aligning with the spot’s low-profile/local reputation.
