The Lowdown
Yo Yo's-The Wedge (reef, advanced) is where it's at for the next couple of weeks. It's a very consistent spot, which is a good thing because this is our only real option on the menu. The water's sitting at 80°, which is pretty much normal for this time of year—nothing unusual there.
The run starts on Monday, 31 August with a solid SW groundswell. The period is 18 seconds, that's some serious long-period energy pulling in, with combined energy of 1335, which is moderate. Monday morning sees 4ft from the SW, with a cross-offshore wind from the SE at 12 mph. The afternoon pushes up to 5ft, still that same cross-off breeze. Surf is clean, but the comment says it's marginal with questionable tide. Still, it's a start.
Tuesday, 1 September, the swell cranks. Morning sees 7ft from the SW, period 18 seconds, and combined energy hitting 2647—that's strong energy. The afternoon holds 7ft with a 17-second period. This is getting into the expert-only zone, over 8ft by the afternoon, but it's a reef break, so it'll handle it. The cross-off SE wind at 15-18 mph keeps things clean. This is a standout, but it's a serious wave.
Wednesday, 2 September, stays solid. 7ft in the morning, 7ft in the afternoon, both from the SW with 16-17 second periods. Energy is still strong (2304 and 2053). Moderate cross-off breeze. Clean conditions. The size is right on the edge for advanced surfers.
From Thursday, 3 September, into Friday, 4 September, the swell backs off. 5ft dropping to 4ft, periods dropping to 14 seconds. Energy drops to 698 on Friday morning—weak. The wind is still cross-off, but the juice is fading.
Saturday, 5 September, picks back up. 6ft from the SSW in the morning, climbing to 6ft in the afternoon, period 16 seconds. Energy rebuilds to 1788. That's a nice little pulse, and the wind stays cross-off. Clean.
Sunday, 6 September, keeps it going. 7ft in the morning, 6ft in the afternoon, from the SSW. The afternoon period jumps to 17 seconds, and combined energy hits 2755—strong. Clean conditions. This is another good window.
Now, a heads-up: Monday, 7 September, the wind swings to a cross-shore from the SSE, 15 mph. The swell is still 7ft from the SSW, but the morning is described as having a cross-chop. The afternoon goes back to cross-off, so the afternoon session is the call there.
Tuesday, 8 September, sees more cross-shore wind and a big jump in energy. The afternoon has 5ft from the SSW with an 18-second period, and the combined energy is 3168—strong. But the wind is cross-shore, so it won't be as clean as the cross-off days.
The real standout of this whole outlook is Wednesday, 9 September. The morning has 8ft from the SSW, 16-second period, with combined energy of 3633. The afternoon hits 8ft, same direction, 16-second period, and energy of 4241—that's strong. The catch is the wind. Morning is a gentle cross-onshore from the S at 9 mph, making it a bit choppy. The afternoon is a cross-shore from the SE at 12 mph. The size is there, but the wind is not ideal. It'll be a challenging, powerful wave.
The second week sees the swell settle into a more consistent pattern. From Thursday, 10 September, through to Monday, 14 September, we're looking at 5ft to 8ft from the SW and SSW, with periods of 14-16 seconds. The winds are mostly cross-off from the SE, which keeps it clean. Energy stays moderate to strong. Not the massive peaks of the first week, but solid, rideable surf every day.
Then Tuesday, 15 September, ends the run with a bump. 7ft in the morning, 8ft in the afternoon, from the SSW, 15-16 second periods, and combined energy of 2389 and 2423—strong. Morning wind is cross-shore from the SSE, but the afternoon goes back to cross-off. Clean finish.
The best of the best is Wednesday, 9 September, with that massive 8ft groundswell and 4241 energy, even if the wind is a bit messy. The second best would be the Saturday, 5 September to Sunday, 6 September window, where you get strong, clean, cross-off conditions with solid SSW swell. Crowds are often at Yo Yo's-The Wedge, so expect company, especially on the weekend. This is a reef break, so the long-period SW groundswell will shape up well, but it's only for advanced surfers. Beginners should stay well away, especially when it's over 5ft.

Information about the Yo Yo's-The Wedge Surf forecast
The above surf forecast table for Yo Yo's-The Wedge provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Yo Yo's-The Wedge can be found by selecting the local surf guide option on the grey menu.

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 Yo Yo's-The Wedge 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.
