Alright, Rusty here. Let’s see what’s cooking over the next 16 days.
The forecast starts on Monday, 13 July, but it’s a slow burn. The first real session doesn’t hit until later, so there’s a few days of flatness. The spot is Osaki Point, a beach and reef break that’s consistent and takes swell from the south-southeast (SSE). The water temp is about normal for the season.
Monday morning, 13 July, is a standout if you’ve got the chops. A solid 7ft swell from the SSW, with a 12-second period – that’s groundswell, packing heavy energy (1151). The wind is glassy, zero, and the waves are for experienced surfers only. That’s too big for the groms. The afternoon fades quick with cross-on wind.
Tuesday, 14 July, is a letdown. Morning has clean 4ft waves but a low score, and the afternoon gets messy. Wednesday, 15 July, is a dud – small, weak onshore at 3ft. Thursday, 16 July, has a glassy 3ft morning but it’s short-period and weak. Friday, 17 July, is a struggle with tiny 1ft and onshore wind. Saturday, 18 July, is a washout with rain and onshore winds.
A dry spell follows. Sunday, 19 July, is poor. Then Monday, 20 July, is the real standout. The morning is glassy again, with a clean 6ft swell from the ESE, 11-second period, and energy of 631. This is the best surf on offer – clean, punchy, and perfect for intermediates up. The afternoon also stays clean with cross-off wind. Tuesday, 21 July, is also strong, with a glassy morning (5ft) and a risky thunderstorm afternoon offering offshore wind and energy of 508. Wednesday, 22 July, keeps the run going with a glassy morning (3ft) and a clean afternoon (5ft, 667 energy). Thursday, 23 July, is still good but smaller.
The second week fades. Friday, 24 July, is small; Saturday, 25 July, is tiny (1ft) but clean offshore; Sunday, 26 July, has a risk of storms but a clean afternoon at 3ft. Monday, 27 July, is back to poor cross-on wind, and Tuesday, 28 July, ends with a glassy but tiny 2ft morning.
The best call is Monday, 20 July, morning at Osaki Point – glassy, 6ft, clean, and consistent. Tuesday, 21 July, afternoon with offshore wind is also a winner. The first week is mostly a miss, so aim for that Monday or Tuesday.
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.
