Alright, Rusty here again, but in feet and miles per hour for you. Let’s break down ADs/Doubles.
For the first week and a bit, it’s rough out there. Sunday the 12th and Monday the 13th have solid swell energy (470-736) with waves running 6 to 7 ft from the ENE. Problem is the trade winds are howling out of the ENE at 25 mph, smashing right across the face. It’s lumpy cross-chop and just ugly. Water temp is 79°, which is about normal for the season, but you won’t care when you’re getting blown sideways.
Tuesday the 14th and Wednesday the 15th see the swell back off to 4 ft to 5 ft, but the wind stays stubborn from the east to east-northeast – cross to cross-on, still choppy. Not worth the drive.
We get a little long-period groundswell from the SSW (14-17 sec) showing up Wednesday afternoon into Thursday the 16th, but it’s tiny – only 2 ft. The wind stays cross-on, so those long lines get chopped up anyway.
Friday the 17th through to the start of the next week is more of the same: cross-shore winds, lumpy conditions, drop in and out of swell. Honestly, if you’re looking to paddle, this is barren.
Around Wednesday the 22nd, another ENE pulse pushes through at 5 ft to 6 ft, but the trade winds are back at 20-22 mph cross-shore. Choppy, messy, no fun.
Now, the one day that stands out is Monday the 27th. We finally get a break in the wind – light and variable in the morning, turning cross-offshore in the afternoon. Swell is small, about 3 ft, but it’s a long-period SSW groundswell pushing 15-17 seconds with serious energy (907-961). That’s the kind of smooth, clean setup that makes ADs/Doubles work. The morning is borderline, but the afternoon window is looking glassy and clean. That’s your best bet – a true standout after a long dry spell.
Don’t get your hopes up for the first two weeks. The wind messes everything up. But that last Monday, July 27th afternoon? That’s the one to circle.

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.
