The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming down the pipe for ADs/Doubles over the next couple of weeks.
Right off the bat, I gotta be straight with you—this forecast is a bit of a tough one. The water is sitting at a warm 80°F, which is pretty much where you’d expect it to be for this time of year, so nothing weird going on there. But for the first few days, the swell is small and the wind is chewing things up. We’re looking at Sunday the 26th and Monday the 27th with onshore and cross-shore winds blowing 22 to 25 mph, turning what little push there is into lumpy, cross-chop. That 3ft to 5ft of mix just isn't making the cut. Get your gear ready for something else.
Now, Tuesday the 28th is where things get interesting. The morning kicks off with a clean 8ft east-northeast groundswell pushing through, and a moderate cross-offshore breeze. It’s rideable and better, but the real standout moment comes Tuesday afternoon. The swell jumps to a solid 10ft out of the east-northeast, with a fresh cross-offshore keeping the faces clean. The wave energy here is serious—strong in the 3336 range. Now, here’s the thing: 10ft is big for this place. This is expert-only territory. Beginners and intermediates should sit this one out; it’s gonna be a heavy, powerful wave.
We roll into Wednesday the 29th, and the morning session is still pumping with that same 10ft from the northeast, but the wind drops to a light breeze at just 6 mph, making it glassy. Again, very clean but very big. By Wednesday afternoon, the swell drops back to a more manageable 7ft from the northeast, the period shortens to 9 seconds, and that light offshore wind is still hanging in there. The energy is still moderate (1066), and the conditions are excellent—this is your sweet spot if you're experienced. It’s a solid day for a paddle.
After that, things fall off a cliff. From Thursday the 30th all the way through to Saturday the 10th of August, it’s grim. The wind is almost constantly cross or cross-onshore, blowing strong, and the swell direction gets messy. There’s a stretch of nearly two weeks where the surf quality is rated poor, with messy chop and lumpy conditions. The wave energy drops right off into the low hundreds, and the only notable event is a clean but small 5ft easterly groundswell on Tuesday the 4th, but it’s still cross-onshore and choppy. Total write-off for a surfer.
The one bright spot in the bleakness is a late window on Wednesday the 5th of August—wait, no, that’s wrong. Scratch that. Looking closer, the poor run keeps going. Honestly, if you’ve got the gear, the beach setup might look more interesting for kite surfing than paddle surfing during these windy days, especially from the 30th onwards when the onshores are solid.
So, the bottom line: Your best bet is Wednesday the 29th of July in the afternoon. Get on the 7ft northeast swell at ADs/Doubles with that light 6 mph cross-offshore wind. It’s clean, it’s got punch, and it’s the only real moment of glory in this entire 16-day window. Everything else is a wait-and-see or a hard pass.
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.

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.
