The Lowdown
Alright folks, Rusty here again. Let’s break it down in feet and miles per hour.
The next few days at Osaki Point are flat and ordinary. From Monday the 20th through the end of the week, we’ve got waves running 1 to 2 feet from the east or southeast. The combined wave energy is weak, reading between 34 and 89. A few glassy mornings might look surfable, but there’s just no push. It’s a gap of several days with nothing worth chasing.
On Monday the 27th of July, the swell finally shows up. Expect 4 to 5 feet from the SSE with a 12-second period. The energy jumps to 703. By the afternoon, 5-foot waves from the south with a clean cross-offshore breeze. This is where it gets interesting.
Tuesday the 28th of July brings a serious jump. Morning sets are 10 feet from the south with a 15-second period. That’s a long-period groundswell, and the combined energy is a strong 4518. This is expert-level stuff. The afternoon pushes 11-12 feet, also clean, but still just for the experienced crew. Crowds will be likely.
Wednesday the 29th of July is the best day of the run. The morning gives you 13-foot waves from the SSW with a 14-second period, glassy conditions, and a massive combined energy of 5788. The afternoon is even cleaner, with 13-foot waves and energy at 6975. This is exceptional surf, but strictly for experts. Water temp is about normal for this time of year.
From Thursday the 30th of July, the wind turns ugly. The swell stays huge at 11-13 feet, but it gets choppy and cross-onshore. Friday the 31st and Saturday the 1st of August are blown out with 10-20 foot waves and strong onshore winds hitting 30-35 km/h. The energy readings are over 14,000, but it’s a mess. This is more kite territory than a clean surf session.
Sunday the 2nd of August is still big with 16-18 foot waves, but the wind swings cross-shore, making it a bit more rideable, though still marginal. By Monday the 3rd and Tuesday the 4th of August, the swell drops to 7-13 feet, and conditions start to clean up again.
The standout is Wednesday the 29th of July. If you’re an expert, get on it early. Glassy, 13-foot SSW groundswell, and Osaki Point at its best. Expect company in the water.

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.
