The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for ADs/Doubles over the next couple weeks. I’ll tell you straight up, it’s gonna be a grim run.
The whole 16-day stretch is basically a write-off. There’s no proper surf on the table. It’s not one of those times where you can pick a window and make it work – this is a consistent dud. The east-northeast trades are just relentless, blowing cross-shore or cross-onshore every single day. That means wind-chop and lumpy conditions from morning to night. The swell ticks over, but the quality is just not there – every single session is marked as poor. You’re looking at a stretch of roughly three weeks where you’d be better off doing something else.
The water temp is about average for this time of year, nothing unusual there. But none of that matters when the waves are junk. The first few days, from Thursday the 10th through Sunday the 13th, you get a mix of swell sizes around 3 ft to 5 ft, but it’s all from the east or northeast, with a short period (7 to 11 seconds). The combined energy is moderate at best (723 down to 188). But the wind is just ruining it – mostly 12 to 22 mph from the ENE, keeping things choppy and cross.
From Monday the 14th right through to Wednesday the 23rd, the pattern holds. Swell drops a bit, hangs around 3 ft to 4 ft most of the time, period short. On the 16th afternoon, there’s a weird spike of a long-period SSW swell (18 seconds) giving strong combined energy (807), but the wind is still cross-onshore and there’s a risk of thunderstorms – not a session to get excited about. Then again on the 18th and 19th, another long-period SSW pulse (17 seconds) cranks the energy up to over 1000 (1059 and 1340), but the wind is howling at 25 mph from the ENE, creating a messy, strong cross-shore chop. That kind of setup, with significant swell and strong onshore wind at a beach break, looks more interesting for kite surfing than paddle surfing.
The last few days, from the 24th to the 25th, it’s more of the same: poor surf, strong ENE winds, lumpy conditions. Nothing changes. Crowds might be low because no one’s out, but that’s about the only positive.
Honestly, there’s no standout here. Not one session worth paddling out for. If you’re desperate, you could sit and watch the long-period groundswells on the 18th or 19th, but with that wind, the shape will be blown out. This stretch looks like a total blank run. Sometimes it just goes like that in this area. Best to wait for the next weather pattern shift – forecasts can change, but for now, I’d give it a hard pass.
Stay patient,
Rusty

Information about the ADs/Doubles Surf forecast
The above surf forecast table for ADs/Doubles provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at ADs/Doubles can be found by selecting the local surf guide option on the grey menu. Our ADs/Doubles 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 (ADs/Doubles) 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 ADs/Doubles 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.
