The Lowdown
Alright, let’s take a look at what’s on offer for ADs/Doubles here. It’s a bit of a tough stretch, I ain’t gonna lie to you. The next week and a half is pretty much a washout for decent paddle surfing. The wind is just relentless out of the ENE, blowing fresh to strong most days, and that keeps the ocean looking lumpy and messy with a cross to cross-onshore chop. We do have some solid swell energy hitting the beach, but the conditions just aren’t letting it show its true colours.
Starting from Monday the 24th of August, we’ve got a 6 ft swell from the east on a short 7-second period, but with a fresh cross-shore wind it’s just poor. That’s the story right through until the end of the month – swell heights bounce around from 2 ft to 8 ft, and there’s even a sneaky long-period southerly energy mixing in on the 26th and 27th with some pretty strong combined wave energy (1061 on the morning of the 27th), but it’s all spoilt by the wind. If you’re into kite surfing, this setup might look more interesting than paddle surfing, because the wind is consistent and cross-shore, but for a surfboard, it’s a no-go.
Things start to look a little different come September. The first few days of the month still have messy winds and poor surf conditions, with swell from the ENE getting bigger – up to 7 ft by the 2nd and 3rd, and the energy is ramping up into the strong zone (1255 on the morning of the 2nd). But then, around the 5th of September and into the second week, there’s a glimmer. On Saturday the 5th, the swell holds at 8 ft to 8 ft from the ENE, but the period jumps to 13 seconds, and that’s a proper groundswell. The combined energy is very strong (1850 to 1960). The wind eases a touch by Sunday the 6th, dropping to a moderate breeze from the ENE at 15 mph, and the conditions finally start to look less messy. By Monday the 7th of September, the wind is down to 12 mph, and the swell is a solid 7 ft to 7 ft from the northeast with an 11-second period. It’s still a cross-shore wind, but it’s just a moderate breeze now, so there’ll be some cross-chop but not the washing machine we’ve been dealing with.
The standout in this whole forecast is the window from Saturday the 5th of September through to Tuesday the 8th. That’s where you want to point your board. The swell direction from the ENE into ADs/Doubles is creating some decent exposure, and the longer period (11 to 13 seconds) means more energy and better-shaped waves, even if it’s a bit straight at a beach break. The water temperature? Well, looking at the first part of the outlook, there’s no anomaly mentioned, so it’s about average for this time of year. You won’t need a thick suit, just your usual summer rubber.
You’ve gotta be aware that this spot can draw a crowd sometimes, so if you hit that window, expect some company. And it’s rated for intermediate surfers, so that 8 ft swell on Saturday the 5th is a bit on the bigger side – it’s fine for experienced folks, but beginners might find it a handful.
To wrap it up, for the next week and a half, you’re better off staying home or finding a different hobby. But hold out for the 5th to the 8th of September. That’s your best chance at some real waves with manageable wind. It’s not perfect, but it’s the best we got.

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.
