October: Autumn Offshore Flow Meets Typhoon Remnants
October is the classic transition month at Omaezaki. The average period eases slightly to 8.8s, but the wind balance improves dramatically: ideal wind reaches its annual peak at 26%, with the first strong continental highs injecting more frequent N/NNW/NE offshore flow. The swell rose is still dominated by E (24.4%) and ESE (24.3%), leftovers of early-autumn tropical systems, but there are enough S/SSW/SW pulses around 13% to combine with cleaner surface conditions and produce excellent sessions.
Water temperatures remain very surfable at 23.2°C, while air cools to 21.0°C. The rain signal stays active at 7.24mm/day, but the frontal passages that bring the rain also bring shifting winds. October is a high-variability, high-reward month: score a day with a fading S/SW swell and offshore N/NNE wind, and you will remember it all winter.
