Ozaki - surf spot statistics

Ozaki, Japan, offers surfable conditions year-round, though the best months for quality waves and favorable winds are typically from July to November. During this period, the swell consistency improves, with ground swell percentages rising significantly in August (29%) and remaining strong through September (27%) and October (25%). These months also bring larger mean swell sizes, averaging 1.5m to 1.6m, providing more powerful and cleaner waves compared to the rest of the year. Wind conditions are most favorable in July and August (29% good winds), though they start deteriorating by September (18%). Early winter months like December and January see smaller swells (1.1m) and poor wind conditions (81-84% bad winds), making sessions less reliable. Spring and early summer (May-June) have high wind swell dominance (90-93%) but suffer from onshore winds 75% of the time, leading to choppy surf. While Ozaki can work in winter, the autumn months—particularly August to October—deliver the best combo of swell size, ground swell contribution, and manageable winds.

February at Ozaki offers surfable conditions with an average swell height of 1.2m and a period of 7.5s, producing moderately clean waves. The most consistent swells come from the NNE and ESE directions, with a notable percentage of waves in the 0.5-2.5m range (NNE: 13.19%, ESE: 16.10%). Larger, rideable waves (1.5-2.5m) are more likely from the NNE (3.78%) and SSW (2.86%) sectors, though peaky conditions are limited. Cross-shore or offshore winds (ideal only 14% of the time) are rare, as dominant winds blow from the N-NNW quadrant, often at 10-30kph, creating choppy or sideshore effects. Expect the best sessions when NNE swells coincide with lighter ENE winds, but prepare for frequent onshore wind interference. Winter consistency is decent, but quality depends heavily on wind alignment. Advanced surfers will find occasional clean sets, while intermediates should target smaller days with ESE energy.
