The Lowdown
Alright, Rusty here again, switching to feet and miles per hour for the same stretch.
The outlook is pretty bleak for the most part. Right from the get-go, it’s a tough start. The first surfable option is on Sunday, August 30, but even then, it’s just small and ordinary. We’re looking at a long stretch of hardly anything worth paddling out for.
The water at Ozaki is sitting at 85°, which is a touch warmer than normal for this time of year. Nice for a swim, but it doesn’t help the waves.
Let’s break it down. Saturday, August 29 is flat and messy. Not worth a second look. Sunday, August 30, we finally see a little pulse. The morning looks best – a glassy 3ft swell from the SSW with period of 7 seconds, and the wind is glass. The combined energy is moderate (114). It’s surfable, but honestly, it’s very ordinary. The afternoon brings a risk of thunderstorms and the wind swings cross-off, turning it even more average.
Monday, August 31 keeps the same small 3ft SSW swell, but the morning is cross-off and clean enough. Again, very ordinary. The afternoon gets ruined by a cross-shore wind and chop.
From Tuesday, September 1 right through to Friday, September 5, it’s a write-off. Onshore winds, poor conditions, and the swell is too small or badly directed. There’s a glimmer on Thursday, September 3 – the swell jumps to 7ft from the SSE with a 12-second period, and the combined energy is strong (1323). But the cross-onshore wind from the east messes it up. That’s really only for experts, and even then, it’s marginal. The afternoon is bigger at 8ft, but still cross-onshore.
The next real standout doesn’t come until Saturday, September 12. The afternoon session is the best on offer for the whole forecast. The wind goes completely glassy with a 3ft swell from the SSW, period pushing 11 seconds. The combined energy is moderate at 303. It’s not big, but it’ll be clean and lined up. Ozaki can get crowded sometimes, but on a small, clean day like this, it could be a fun little session.
Anything in the second week is promising but less certain. Sunday, September 13 is okay in the morning, but the wind is cross-onshore, so it’s not as good.
To sum it up: the only real standout is the Saturday afternoon, September 12. Clean, glassy, small but workable. The rest of the window is mostly a dud.
Rusty, signing off.

Information about the Ozaki Surf forecast
The above surf forecast table for Ozaki provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Ozaki can be found by selecting the local surf guide option on the grey menu. Our Ozaki surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Ozaki) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Ozaki may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
Ozaki is 11 km (7 miles) from Muroto. If you plan a holiday in Shikoku, look for hotels and other accommodation in Muroto. Muroto has rooms for a wide range of budgets as well as car hire and transport links.
