The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s shaping up for this stretch of coast.
We’ve got a real slow start on the cards. The first week or so is pretty flat, with only tiny, weak swell pushing through. The real story here is a massive pulse of energy that arrives in the second week, turning things on their head for a few days, but it’s not without its issues.
Osaki Point is the only game in town, and for the first few days it’s a struggle. Sunday the 26th kicks off with a tiny 1ft SE swell, period of 15 seconds, so it’s got that long-period groundswell feel but no size. The morning is glassy, making it clean for the odd little wave, but the energy is weak (168). The afternoon gets a bit of a cross breeze, and it turns to poor conditions. Monday the 27th morning is more of the same, but the afternoon sees a little bump up to 2ft from the S with a period of 9 seconds and a clean cross-off wind. It’s still small, but that’s actually the best looking session of the first week. The water temp is about average for this time of year.
Tuesday the 28th through to Friday the 31st of July are a write-off. The swell is tiny, the winds are messy, and the energy readings are pitiful, mostly in the double digits. It’s a real flat spell. Saturday the 1st of August and Sunday the 2nd are also poor, with light onshore winds and not enough push to do anything.
Then everything changes. Monday the 3rd of August starts to show some life, with the swell building to 4ft from the ESE, period of 16 seconds. The energy is now moderate (683), but the wind is a steady cross-onshore, so it’s a bit choppy and marginal. Not the best introduction to the new swell.
The standout window is Tuesday the 4th of August. The morning session is the pick of the entire forecast. We’re looking at a solid 8ft swell from the ESE, with a very long period of 17 seconds, and the wind is glassy. The combined energy is strong (3308). That is a proper groundswell, and with glassy conditions, it’s going to be an excellent session for experienced surfers. The afternoon steps up to 8ft but the wind goes cross-shore, so it’s not as clean.
From Wednesday the 5th through to Saturday the 8th of August, the swell is huge, running between 10ft and 16ft, with periods of 16 to 18 seconds. The energy readings are massive, climbing to 12,623. This is expert territory, well over 8ft. The problem is, the wind is onshore or cross-onshore for most of this period, making it choppy and messy. The setup at Osaki Point is a beach and reef, so with that much swell and onshore wind, it’s going to be a messy, powerful beast. It might hold some interest for the experienced crew, but the conditions won’t be pristine. The sheer size and energy mean it’s really only for the brave.
Sunday the 9th of August sees the swell start to drop, back to 12ft in the morning and 8ft in the afternoon. The wind is still onshore and cross-onshore, so it’s still a messy, powerful affair. By Monday the 10th of August, the swell has faded back to 3ft, and the energy is weak again.
So, if you’re after the best of it, Tuesday the 4th of August morning is your absolute standout. Glassy, solid groundswell, and that’s the cleanest we’ll see it. The rest of the big swell window is a raw, powerful, and windy affair. The first week is a bust.
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.
