Alright, Rusty here again. Let’s break it down in the old numbers. For Osaki Point, don’t jump in too quick – it starts quiet. The water’s sitting at 77°F, which is a tick colder than average for the season, so grab a spring suit.
Monday the 6th offers a clean little starter: 3ft from the SE, combined energy of 449, and a light offshore breeze. Tuesday and Wednesday stay small and bumpy, with the swell building. By Wednesday afternoon we’re looking at 8ft from the SE (energy up to 3732), but that cross-onshore wind messes with the perfection.
Thursday the 9th brings the power up to 10ft from the SSE, a long 16-second period, and energy climbing into four digits. Still a bit textured with the wind, but the potential is there.
Now, Friday the 10th is where things get serious. Solid 12ft to 13ft swell from the S, with a very long 17-second period. Energy is massive – 8244 in the morning and a huge 11190 by the afternoon. The wind stays light and cross-onshore, so not glassy, but the raw power is off the charts. This is for experts only; 13ft is no joke.
But the absolute standout is Saturday the 11th. Saturday morning delivers 15ft from the SSW (energy of 12327), and then Saturday afternoon goes glassy. Flat calm wind, 13ft from the SSW, 16-second period, and energy at 9388. The guidance calls it exceptional for experts. This is the best session in the whole 16-day window. Expect crowds to be a factor – quality like that draws a crew.
The swell fades fast after that. Sunday the 12th drops to 8ft with cross-on wind, and by Monday the 13th it’s back to 5ft and glassy – clean but small. The second week is a mix of clean small waves and a lull, with energy dropping into the hundreds. The 19th and 20th show a little pulse of 7ft from the ESE with glassy conditions on the 20th afternoon – a fun, cleaner option for a session.
Mark your calendar for Saturday the 11th. That’s the one.

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.
