Conditions at Ozaki in October
October: Maximum Period and Prime Autumn Windows
October offers the longest average wave period of the year at 9.5 seconds, and the swell direction shifts even more favourably toward the east. ESE swell dominates with 36.8% of all observations, followed by SE at 26.5%, while the 1-1.5m (3-5ft) and 1.5-2m (5-6.5ft) classes are well populated across the ESE and SE directions. This is the month when true groundswell, often from distant typhoons or deepening North Pacific lows, reaches Ozaki with real power. However, ideal wind conditions drop to 12% as the northeast monsoon reasserts itself, with NNE at 21.4% and NE at 22.2% blowing onshore for long stretches. The key is timing the cold-front passages that briefly deliver W/NW offshore winds. Water temperatures are still pleasant at 25.5°C, air temperatures average 20.7°C, and rainfall eases to 5.68mm per day.
