The Lowdown
G’day crew, Rusty here. Looks like we’ve got a slow start, but once it gets goin’, this region has some proper groundswell on the way. The first good session won’t be until Sunday the 13th, and the run of waves will stretch right through to the end of the month, so plenty to look forward to if you’ve got patience.
The standout in this whole period is Yo Yo’s–The Wedge, an advanced reef set-up that’s very consistent and exposed to the SW swell. Best direction is SW too, which lines up nicely. Water temps are about average for this time of year, so nothing weird goin’ on there.
Sunday the 13th kicks things off with a solid 6ft SW groundswell at 18 seconds – that’s very long period, and the combined energy is pumping at 2532 (strong). The wind is going SSE at 12 mph, which is cross, so the morning will have a bit of chop. But Sunday afternoon cleans up nicely: wind swings SE at 16 mph, cross-off, swell bumps to 7ft, still 17-second period, energy up to 2823. The session is marginal on the charts, but for a reef break, that long-period groundswell with cross-off wind will handle well. It’s for advanced surfers only – no beginners on a 7ft set.
Monday the 14th holds 6ft SW, 16 seconds, with SE wind at 12–16 mph (cross-off), so clean surf, though the energy drops to around 1707 (still moderate). Crowds are ‘often’ here, so expect company.
Through the middle of the week, the swell hangs around 6ft to 7ft, periods dropping to 14–15 seconds, with cross-off winds most afternoons. Not epic, but rideable for the crew who know the reef. The best shape will be on the afternoon sessions when the wind is clean.
Now, the true standout window arrives Sunday the 20th afternoon: swell bumps to 7ft SW, 16 seconds, combined energy of 2001 (moderate-strong), wind is SE 9 mph, cross-off, and conditions are rated excellent for experienced surfers. That’s the pick of the fortnight – clean, solid, and lined up.
Monday the 21st afternoon also looks good: 6ft SW, 14 seconds, light SE at 6 mph cross-off, energy 1323, excellent conditions. Tuesday the 22nd fades a little but still clean afternoons.
Then from Wednesday the 23rd through Thursday the 24th, the swell picks back up: 7ft to 7ft SSW, 15–16 seconds, cross-off wind from SE at 12–16 mph, energy in the 2300–2471 range (strong). That’s a solid mellow reef swell, but the period is still long, so the reef will handle it beautifully.
The biggest pulse comes Friday the 25th: 8ft SSW, 18 seconds, with combined energy screaming at 4625 (very strong) in the morning, though the wind is cross from SSE at 12 mph. The afternoon is the go: 8ft, 17 seconds, cross-off SE at 16 mph, and the energy is 4274. This is expert territory – do not paddle out if you’re not solid. The long period means long lulls, but the sets will be thick and heavy on the reef.
After that, the last weekend (Saturday 26th and Sunday 27th) holds around 6ft to 7ft SSW, 15–16 seconds, with gentle to moderate cross winds. It’s still surfable, especially Saturday morning, but the magic is gone by Sunday afternoon with more cross-chop.
Monday the 28th wraps it up with 6ft SSW, 14 seconds, light cross-on wind – a clean fade-out.
Overall, the best on offer is Sunday the 20th afternoon and Friday the 25th afternoon. The 20th is more forgiving for strong intermediates (7ft), the 25th is only for the experts (8ft). Don’t miss that window.
Stay salty,
Rusty

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.
