Alright, Rusty here. Let’s break down what’s headed for Osaki Point.
We’re starting off slow. The first few days are flat and poor, through Friday 3rd July and into the weekend. Saturday and Sunday mornings are tiny, with swell around 1.0ft to 3ft and short periods, so there’s nothing worth paddling for. Even when it goes glassy on Sunday morning, the swell is just too small.
Monday 6th July afternoon shows a spark: a 3ft SE groundswell with a 14-second period, glassy conditions, and a combined energy of 281 (moderate). Still small, but clean.
Tuesday 7th July afternoon brings a big jump: 7ft of SE swell with an 18-second period and combined energy of 2586 (strong). Light cross-shore wind. This is big and only for experienced surfers – anything over 8ft is expert-only.
The real standout is from Wednesday 8th July through Saturday 11th July. Wednesday morning hits with 10ft of SE swell at 17 seconds and combined energy of 8897 (very strong). Light cross-onshore wind. By Friday 10th July afternoon, it peaks: 15ft of S swell at 17 seconds, combined energy 10932 (very strong), with clean cross-offshore winds. Exceptional for experts. Saturday 11th July morning is equally powerful: 15ft of SSW swell with offshore WSW winds at 6 mph – pristine. Water temperature is around 77°, pretty average for this time of year.
Sunday 12th July offers a more manageable 6ft to 7ft of S/SSW swell with glassy or clean conditions, good for experienced surfers. After that, through the second week, it drops back to smaller waves around 3ft to 4ft with some glassy mornings, but nothing special.
The best calls are Friday 10th July afternoon and Saturday 11th July morning at Osaki Point. Massive, long-period groundswell, clean winds, and extreme energy. Pure big-wave territory. If that’s too much, Sunday 12th July is your best bet for solid but manageable surf.
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.
