Righto, grab your wettie and listen up. It's Rusty here.

We’re looking at a bit of a slow start at Osaki Point (beach and reef). The first few days are pretty average, with a cross-onshore breeze and marginal conditions. Don't get too excited about Tuesday the 7th or Wednesday the 8th – the swell is there, but the wind's junk and the wave comment’s not inspiring anyone. The water’s sitting at 77°, which is a touch colder than what we'd usually expect this time of year.

The real action kicks off from late in the week. Thursday the 9th is a step up with a solid 10ft SSE groundswell, but it’s still a bit scratchy. The standouts are Friday the 10th afternoon and Saturday the 11th. That’s where it’s at. Friday afternoon hits with a 13ft S swell at 17 seconds – that's serious, long-period energy coming through. The swell energy is massive, so there’s plenty of power. It's big – over 8ft – so this is for experts only. The wind is light cross-onshore, so it won't be perfect, but the size and period make it the most interesting session of the whole outlook.

Saturday the 11th is also massive, with 15ft swells from the S and later SSW. The energy figures are through the roof. Again, expert territory. The wind stays light, so the surface won’t be too chopped up, but watch for those long 17-second groundswells – they’ll be wedging up on the reef, offering some proper barrels if you’ve got the nerve. It’s exposed to the SSE swell, so it’ll pick up all that energy.

Then Sunday the 12th morning is a classic: 10ft SSW swell, dead calm glassy conditions, and a clean forecast. That’s the one for experienced surfers who want power without the full-on chaos of Friday. It drops through the rest of the week, with Monday the 13th and Tuesday the 14th offering much smaller, cleaner waves in the 4ft to 6ft range – good for intermediates, especially with glassy mornings and clean afternoons.

We’ve got a quiet spell from the 15th to the 17th, with tiny 3ft to 4ft waves. There’s a little pulse on Saturday the 18th afternoon, with a clean 10ft SSE swell arriving – that’s another decent option for experienced surfers. Sunday the 19th morning is also clean with 8ft swell from the ESE, but the wind turns cross-onshore by the arvo. After that, it fades out into the 20th and 21st with onshore wind and small, weak swell, and by the 22nd it’s a write-off with poor conditions.

So in short: the best waves are Friday the 10th afternoon and Saturday the 11th for the big-swell crew, and Sunday the 12th morning for the clean, powerful session. The rest is a mix of small clean waves for the learner/intermediate crew or straight-up junk.

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.
