The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a solid run of SSW groundswell on the cards for Yo Yo’s-The Wedge, starting Monday the 10th of August and running right through the 16-day window. This is a reef break, exposed and very consistent, so it’s a spot that will fire when the conditions line up. The water temp is about average for this time of year, so nothing crazy there.
The first few days, Monday the 10th through to Wednesday the 12th, are a bit of a mixed bag. Monday morning kicks off with a 5ft SSW swell but the wind is cross-shore and the surf is messy. It’s not a write-off, but it’s not pretty. The afternoon cleans up nicely though with a 10ft SSW swell and clean, cross-off wind. That’s a big wave, over 8ft, so this is for experienced surfers only. The combined energy is strong at 4951 (moderate-to-strong). Tuesday the 11th holds that 10ft to 8ft range with clean conditions all day – that’s the standout for the first week. The period is dropping from 18 seconds to 16 seconds, still long-period groundswell, so it’s going to be powerful and lined up, but at a reef break like this, it’ll handle it well. The energy is still strong.
Wednesday the 12th through to Friday the 14th sees the swell dropping a bit, 6ft to 8ft, still clean in the afternoons but the wind swings a little cross-shore some mornings. The energy is moderate (2302 to 1938). The surf is still solid and rideable, but not as epic as the Tuesday peak. Crowds are often here, so expect company.
The weekend of the 15th and 16th brings another pulse. Saturday the 15th has a 7ft SSW swell, but the morning is cross-shore and a bit choppy. The afternoon cleans up. Sunday the 16th is the real gem of the second week: a 7ft SSW swell with 16-second period, light cross-off breeze in the morning, and the report says *excellent surf conditions for experienced surfers*. The energy is moderate (2080). That Sunday morning is the top pick of the whole run.
After that, the swell slowly fades from the 17th onward, dropping to 5ft on Monday and down to 3ft on Tuesday the 18th morning. That Tuesday morning, with a 3ft SSW swell and 17-second period, is actually noted as *very good surf conditions* – small but clean and long-period. The afternoons pick up again with a fresh 5ft SW swell on Tuesday afternoon, and then from Wednesday the 19th through Friday the 21st, we see a solid 8ft SW swell pulse with strong energy (4046 to 3079). That’s another big swell, clean cross-off wind, but again, over 8ft, so it’s expert territory. The swell direction shifts to SW, which is offshore for this spot.
The last few days, from Saturday the 22nd to Tuesday the 25th, the swell backs off to 8ft down to 6ft, still clean but the wind gets a bit fresh (19 mph) on some afternoons. The energy drops to moderate (2391 to 1308). Still surfable, but the magic is fading.
The standout day is clearly Sunday the 16th of August – morning session. That 7ft SSW groundswell, long period, light cross-off breeze, and excellent conditions for experienced surfers. Close second is Tuesday the 11th of August – biggest, cleanest, and most powerful of the first week.
Rusty out.

Information about the Yo Yo's-The Wedge Surf forecast

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.
