The Lowdown
Right then, let's have a look at what's on offer at A-Ds-Doubles over the next couple of weeks. Gotta be honest with ya, it’s a slow start and a long stretch of pretty average conditions, but there is one morning that’s gonna make it all worth it for the crew that can get out there.
Right now and through the end of July, a solid east-northeast wind is just messing things up. We’ve got a decent push of swell, around 6ft of east swell with a combined energy of 1574 (strong energy) on Monday afternoon, but that 19 mph cross-shore wind is making it lumpy and chopped out. It’s not great out there, and the water temp is sitting at 80°, which is pretty normal for this time of year.
Come Tuesday the 28th, the swell bumps up to 8ft from the east with a period of 13 seconds, and the energy is pumping at 2334. The wind is a cross-offshore, so it’s cleaner, but it’s still a solid 19 mph. That’s decent, but it’s pushing into the size where it’s getting too big for beginners. Tuesday afternoon stays similar with 8ft.
Now, here’s the one you’ve been waiting for. Wednesday the 29th morning. That’s the standout. The wind drops right out to a glassy 3 mph from the south. We’ve got a nice 7ft swell running from the east-northeast with a period of 10 seconds and combined energy of 986 (moderate). It’s going to be clean, smooth, and offering some proper waves. That’s the window. The crowd factor is ‘often’, so expect some company, but for a morning that good, it’s worth it.
Wednesday afternoon the wind swings onshore from the southeast, and it goes to marginal. After that, we’re into a real rough patch. From Thursday the 30th all the way through to Sunday the 11th of August, it’s a long, bleak run. The wind just stays hammering from the east-northeast at 16 to 28 mph, mostly cross or cross-onshore. The swell hangs around between 5ft and 10ft, but it’s all short period, messy, and blown out. Late in the window, around the 10th and 11th of August, a long period 15-17 second south-southwest swell shows up, but it’s small – only 3ft – and the wind is still cross-shore or onshore. The swell direction doesn’t match the optimum east-southeast direction for the break, and with that period, it’ll be tough to find a decent bank at a beach setup. It looks more like a kite-surfing setup than a paddle-surfing one through most of that second week, to be honest.
So, to wrap it up: Wednesday the 29th morning at A-Ds-Doubles is your only real shot at something special. Get on it if you can. The rest of the outlook is a write-off until the forecasts change.

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.
