Alright folks, Rusty here. Let’s get into it.
We’ve got a real mixed bag coming up for Osaki Point over the next couple of weeks. The opening days are a bit of a tease, but there’s a definite standout window that’s worth clearing your schedule for.
The first big call is this Sunday morning, the 12th. It’s not for the faint of heart. We’re looking at a solid 13ft swell from the SSW, with a long 16-second period pushing a massive amount of energy through (7660). The wind is light offshore from the WSW, so it’ll be clean. This is expert territory only – that size is no joke. The water is sitting at 78°, which is a bit colder than usual for this time of year, so you might want a thin spring suit if you’re not used to it.
Sunday afternoon drops a touch to 12ft, still from the SSW and still clean with offshore wind. Still excellent for experienced surfers.
Monday morning the 13th is a treat. The swell drops to 7ft with a 12-second period, but the wind goes dead calm – glassy as a mirror. The energy is still solid (1151). This is the sweet spot for the whole first week. It’s big enough to get you into some excellent waves, but clean enough for a good session.
From Monday afternoon through to the end of the week, things get smaller and the wind starts to mess with it. The swell drops to 6ft and smaller, and while some windows are glassy, the consistency fades. By Wednesday the 15th, we’re down to 3ft and onshore winds, and it’s pretty much a write-off through the end of the week.
There’s a bit of a lull, but don’t write the whole forecast off. The real gold is a week away, on the 22nd of July. Tuesday morning, the swell comes back up to 6ft from the ESE, with a long 13-second period, and the wind is absolutely dead calm – glassy. The energy is strong (1230). This is a standout. It’s a bit of a long-range call, so don’t bet the farm on it, but if it holds, Osaki Point is going to be firing and clean. The afternoon stays clean too with 6ft and a light cross-offshore breeze.
The days leading up to the 22nd are mostly ruined by onshore wind, and the 23rd and 24th offer smaller, cleaner waves, but nothing that compares to that Sunday/Monday window or the promise of the 22nd.
To be honest, the best bets are this Sunday morning for the brave, Monday morning for the experienced, and that long-range call for the 22nd of July. Everything else is a bit of a gamble or just small and sloppy.
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.
