The Lowdown
Alright, Rusty here, breaking it down in feet and miles per hour.
We’re starting off slow and small, so don’t rush. The first real chance to wet your line is Tuesday morning, 28 July, at Osaki Point. A 2ft south swell with a light offshore breeze will get you a few little ones, but it’s pretty ordinary. The combined energy is weak (129). The water is running at 84°, which is a touch warmer than normal for this time of year.
The next few days are flat and quiet. Wednesday morning, 29 July, has a 2ft SE swell, still light offshore, but it’s very ordinary. Thursday morning, 30 July, is glassy with a 1ft ESE swell, but wave energy is very low (52). It’s more of a paddle day than a surf day.
Friday through Sunday, 31 July to 2 August, are mostly poor. Early Sunday morning, 2 August, we get a bump to 2ft, but the big change is the period jumping to 14 seconds, bringing some life. The combined energy climbs to 187. That’s a long-period groundswell, so it’ll have more shape and power, but at a beach-and-reef setup like Osaki Point, those long-period swells can break a bit straight. Still, the glassy morning makes it worth a look.
The real standout is Monday 3 August and Tuesday 4 August. Monday morning sees a 5ft ESE swell with a 16-second period, and the combined energy rockets to 1189. That’s a solid, powerful groundswell. The wind is onshore, so it’ll be a bit lumpy, but the size and period are there. Tuesday 4 August is even bigger: 10ft ESE swell, 18-second period, and combined energy of 5329 in the morning, 6739 in the afternoon. That’s serious wave energy. At 10ft, this is expert-only territory at Osaki Point. The wind is cross-onshore, so it’ll be a bit gnarly. If you’re experienced and know this break, Tuesday is the best on offer, but it’s not for beginners.
Wednesday 5 August is a write-off. A massive 20ft east swell with 19-second period and combined energy of 26036 is way too big for this break. The wind is onshore too. Just don’t even think about it.
Thursday 6 August through to Tuesday 12 August is a mixed bag of poor conditions, strong winds, and messy seas. The wind gets crazy strong on Friday 7 August – near gale-force from the east at 37 mph – so it’s blown out completely. Saturday and Sunday, 8 and 9 August, are still messy with cross-shore winds and lumpy chop.
The last chance in the window is on Tuesday morning, 11 August. A 3ft E swell, 11-second period, and glassy conditions. The combined energy is 275, so it’s moderate. It’s a small, clean morning session, but nothing special.
Bottom line: Tuesday 4 August is the standout, but only for experts. For everyone else, the early morning glassy sessions on Sunday 2 August or Tuesday 11 August are your best bet for a few clean, smaller waves. The rest of the window is mostly a write-off due to small size or nasty wind.
Rusty.

Information about the Osaki Point Surf forecast
The above surf forecast table for Osaki Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Osaki Point can be found by selecting the local surf guide option on the grey menu. Our Osaki Point 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 (Osaki Point) 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 Osaki Point 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.
Osaki Point is 14 km (9 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.
