The Lowdown
Alright, this is Rusty, talkin' about what's comin' down the pike. It's a bit of a mixed bag, so let's break it down.
First up, we're lookin' at Osaki Point. The water's sittin' at a warm 84°, which is a touch warmer than normal for this time of year, so you can leave the thick wetsuit at home. The real story here is that we've got a solid swell pulse from the south right now, with serious energy in the water. The combined energy is readin' a hefty 1831, which is strong, pushin' in a 7ft S swell at 11 seconds. That's a long-period groundswell, and it'll be wrappin' nicely into the point. The wind is a bit of a letdown for Saturday morning though, a cross-on E breeze at 9 mph making things a little lumpy. It's surfable, but it's not the cleanest picture.
Now, if you can wait, Monday morning, the 10th of August, is where it gets real interesting. The wind drops to almost nothing, a glassy ENE breeze at 3 mph, and the swell settles to a clean 4ft from the east with a solid 12-second period. The combined energy is still a strong 1165, and the surface will be like a mirror. That's the standout session for the week, perfect for experienced surfers lookin' for some clean, lined-up waves. The crowd factor is "sometimes" here, so on a morning like that, you might have a few mates out, but it's worth the paddle.
The following days stay okay with some clean conditions, but the swell starts to taper off. By Thursday the 13th, things get real sloppy and small, with onshore winds and poor quality surf. You'll see a few days of flatness and choppy windswell in the middle of the second week.
Lookin' further out, there's a spike in the forecast on the 19th of August at 8ft from the east, but that's a short period, 9 seconds, with onshore winds. That's a lot of water moving around in a messy way—too big for beginners, and the wind will make it a battle. That setup is more interesting for kite surfing than a clean paddle session. The combined energy there is a whopping 1047, but it's all for the wrong reasons.
The very end of the run, around the 21st and 22nd of August, starts to clean up again with small, glassy conditions and a light S swell. It's a promising sign, but it's a long way out, so we'll see if it holds.
Overall, if you're lookin' to get the best of this window, you've got to be on it Monday morning, the 10th. That's the one.
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.
