Alright crew, Rusty here again, this time with the numbers in feet, miles per hour, and Fahrenheit. We’re looking at Osaki Point over the next couple of weeks.
The first few days are small and clean, nothing to write home about – just a few waist-high waves to keep you limber. Then around Wednesday 8th July, the ocean starts to wake up. By the weekend of 11th and 12th July, we’ve got a serious, powerful swell on our hands. The real standout is Saturday 11th July – we’re talking 15ft waves from the SSW, with a long period around 17 seconds, and combined swell energy hitting a massive 13128 – that’s strong to very strong energy. This is expert territory only, way over 8ft. Winds are light cross-onshore, so it’ll be lumpy but rideable for those with the skill. Crowds are likely at this consistent spot.
Water temp is about 77°F – just a touch cooler than average, nothing wild.
Earlier that week, Wednesday 8th July afternoon shows 10ft from the SE, 17-second period, energy 5191 – still big. Thursday 9th is even bigger with 12ft but wind gets choppy. By Sunday 12th the swell drops to 10ft but with cross-onshore wind and shorter period, losing quality.
The second week starts off nice: Monday 13th July morning is glassy with 5ft from the SSW – clean and fun for a smaller session. After that it fades to 3-4ft with clean conditions through the week, nothing standout.
Later, around Sunday 19th July, another pulse of 13ft from the E shows up – energy 5169 – but wind is onshore and period shorter, making it messy.
Best bet: Saturday 11th July for the adrenaline junkies, and Monday 13th July morning for a glassy, smaller session. Long-range stuff after that is promising but less certain.
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.
