The Lowdown
Hey, Rusty here. Let’s be straight – the next two weeks at ADs/Doubles are a dud. Nothing worth paddling out for.
From Sunday the 13th of September, it’s cross-shore wind at 12 mph from the ENE, and the swell is tiny at 2 to 3 feet, with a short period of 8-9 seconds. Energy is weak (around 274). That sets the tone.
The wind stays cross the whole time, picking up to 22 mph by Wednesday the 16th, with swell at 4 feet but a period of just 6 seconds – all windswell. Thursday the 17th gets rough: 25 mph cross-winds, 7 to 8 feet of swell, but it’s messy cross-chop. That’s big enough for experts only, but the wind kills it.
By the weekend of the 20th, it’s still cross-wind at 22 mph, 7-foot swell, but lumpy. Honestly, this looks more like a kite-surfing setup than a surf one. The biggest waves come on Saturday the 26th and Sunday the 27th: 8-foot swell with energy up to 1130, but the wind is cross-to-onshore and the period is a short 7-8 seconds. Best score is a 2 out of 10 on the 26th and the morning of the 28th, when the wind drops to 6 mph from the NE and the swell is 6 feet. Still, it’s cross-shore ripples and short period.
No standouts. No clean windows. The only saving grace is that this break is fairly consistent normally, so a bad run like this can change. But for now, don’t bother.
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.
