Alright, Rusty here. Let’s have a look at what’s coming up.
We’re starting with a big pulse of groundswell hitting Osaki Point. This is a serious swell event, folks. Friday the 10th sees a heavy 13ft S swell coming in with a very long 17-second period. That’s a lot of ocean energy moving – combined energy is a strong 8749. The water’s running a bit colder than normal at 25°, about 2° cooler than usual for this time of year. The wind is light and cross-shore, which isn’t ideal, but on a setup this exposed, the size will be the main story. This is expert-only territory at over 8ft.
Saturday the 11th builds even more. The morning holds 15ft from the S, still with that long 17-second period and combined energy jumping to 11977. The wind remains light and cross, so it’s a beast. But look at Saturday afternoon: the wind swings to a light cross-offshore from the S, and the swell shifts slightly to SSW at 15ft, period still a massive 17 seconds, and combined energy tops out at 12304. This is the standout session for the really experienced crew. It will be clean and powerful, but absolutely not for beginners.
Sunday the 12th morning might be the pick for those who can handle it. The wind goes light offshore from the WSW, with a 13ft SSW groundswell at 16 seconds. That’s a long period, so it will be bowling on the reef. The combined energy is 8170. Sunday afternoon drops a touch to 12ft but the offshore wind holds, making for excellent conditions.
Monday the 13th is a treat. The morning drops to 7ft, but we get glassy wind from the WSW – light air, no wind ripples at all. SSw swell at 12 seconds. Combined energy is down to 1180, so it’s much more manageable. This is going to be clean, fun, and should be a good size for intermediates. The afternoon stays glassy with the swell around 6ft. This is probably the best call for most surfers who aren’t chasing the mutant swell.
From Tuesday the 14th into the following week, the surf drops right off. A long gap kicks in with tiny, poor-quality swells and unfavourable onshore or cross-onshore winds. The combined energy drops to just a few hundred. This stretch looks like a write-off for paddle surfing. There’s a slight bump on the 19th and 20th with some S swell around 6ft-6ft, but the wind is onshore or choppy, and the energy is moderate at best. Not a great run.
Now, looking way out to Thursday the 23rd and Friday the 24th of July, there’s something brewing again. Thursday morning we see glassy conditions again, with a 6ft ESE groundswell at a solid 13-second period. Combined energy jumps back to 1979. The wind is glassy. That’s a promising sign for clean, shaped-up waves. Thursday afternoon holds with a light cross-offshore wind. Friday the 24th looks bigger at 7ft from the SE, but the wind is onshore, so it’s a bit more of a mixed bag.
The absolute standout here is Saturday afternoon the 11th and Sunday morning the 12th at Osaki Point. That’s a very long period, consistent groundswell with clean offshore or cross-offshore winds, and massive energy for those who can handle it. For the rest of us, Monday the 13th with glassy wind and dropping swell is the one to aim for.
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.
