Alright, this is Rusty coming to you from the check. Let’s talk about the next couple of weeks at Osaki Point.
We’ve got a pretty mixed bag on the way. The first few days are a write-off, with cross-onshore winds and messy conditions that are just not doing the place any favours. The real action starts to fire up from Friday the 10th, and that’s where we see the standout swell. The water is sitting at 77°, about a degree colder than usual for this time of year, so you might want a spring suit.
The best of the whole run lands on Friday the 10th. We’re looking at a solid 13ft to 15ft swell from the south, with a very long 17-second period. That’s proper groundswell energy, and the combined energy readings are huge, hitting a whopping 8642 in the morning and over 11000 in the arvo. That’s serious power. Winds are light, starting offshore in the morning at 3 mph from the NE, then going cross-shore in the afternoon. For a beach and reef setup like this, that long-period S swell is going to line up beautifully. This is for experienced surfers only, it’s big, powerful, and will sort the men from the boys.
Saturday the 11th keeps the quality high with similar size and period, around 15ft from the S-SSW and winds staying light. The energy levels are still massive, over 12000. It’s still heavy, so don’t be a hero unless you’re on your game.
Sunday the 12th is interesting. The swell drops to a still-chunky 12ft from the SSW, but we get a glassy, dead-calm morning. The energy is still well up there at 5205. That’s a serious session for the experienced crew. Afternoon sees it drop further to 8ft with clean cross-off winds, which is excellent for the more competent intermediate.
From Monday the 13th onward, the swell backs right off. We’re into 3ft to 5ft range for most of the second week, with periods dropping and winds flipping around. There’s a few glassy mornings on the 17th and 21st of July where the waves will be clean but small, fun for a longboard or a twinny, but nothing to get excited about. The energy levels are low, under 1000 on most of those days. The period is around 11-12 seconds, so it’s a cleaner, weaker groundswell but it won’t have any punch.
The last noticeable bump comes around the 20th of July, with 8ft swell from the ESE and a 14-second period, but the winds are cross-onshore and it looks average. The week after that, the 22nd and 23rd, show some glassy starts but the swell is inconsistent and the wind gets up, making for poor quality.
So to sum it up: the absolute standout is Friday the 10th and Saturday the 11th of July. That’s the big, long-period groundswell with light winds. If you can only get in the water once in this whole 16-day window, make it one of those days. It’s going to be heavy, but epic.
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.
