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.

June at Ozaki offers decent surf conditions with an average swell height of 1.4m and a period of 7.8s, indicating generally rideable waves with reasonable energy. The swell direction is predominantly from the south and southeast, with the most consistent waves coming from the SSW direction, where 10.61% of swells fall in the 1-1.5m range and another 5.83% reach 1.5-2m. This suggests a mix of smaller, user-friendly waves alongside some punchier sets, suitable for intermediate to advanced surfers. However, wind conditions are less favorable, with only 25% of the time providing ideal offshore or light wind conditions. The prevailing onshore winds often come from the WSW and SW directions, increasing in strength (20-30kph range) about 3.35-3.73% of the time, which can create choppier surfaces. Early mornings may offer cleaner conditions before the wind picks up. Overall, June delivers surfable waves, but patience and timing are key to scoring the best sessions.
