The Lowdown
Alright, Rusty here, breaking it down for Osaki Point.
We’ve got a dry spell at the start – the first real chance of a wave you’d paddle out for isn’t until the morning of Tuesday, July 15th. The next week and a half is mostly small stuff and average conditions.
The big red circle on the calendar is the morning of Tuesday, July 28th. That’s the best swell of the run: a clean 1.2m from the southeast, glassy conditions with a light 5 km/h easterly, and a solid 11-second period. Water temp is 79°, right around average for this time of year. The combined energy hits 408, which is a strong, punchy push. It’s an intermediate spot, so you’ll want a bit of experience. Might be a few folks out – it gets crowded sometimes.
A little earlier, the morning of the 25th is also worth a look. It’s small – only 0.4m – but that swell is coming from the southeast with a very long 16-second period. That kind of groundswell will wrap into this point perfectly, with glassy conditions. The energy is moderate at 203. A quieter, more promising option for the second week.
The 28th is the big one. After that, the 29th still has some size but the winds turn cross-shore and the quality fades.
Bottom line: don’t waste your time early on. Aim for that 28th.

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.
