Monobegawakakou

Best Surf Season (September - November)

The Pacific around Shikoku is at its restless best from late summer into autumn. This is when the tropical cyclone machine of the northwest Pacific spins up, and Monobegawakakou's south-facing stretch starts receiving consistent, longer-period swell out of the SE, SSE and S. September and October are the crown jewels: average periods climb to 9.3-9.5s, ideal offshore wind windows hit 46-56%, and water temps remain in the low-to-mid 20s (72-77°F / 22-25°C). As the Siberian High begins to strengthen, N, NNW and NNE winds groom the lines between passing systems. November carries the same storm track but with slightly less energy and smaller average heights, though the combination of clean offshore wind and lingering warm water can still produce excellent sessions.
