Hey, Rusty here. Let me break down what’s on the menu for ADs/Doubles.
Gotta be straight with you—it’s a tough couple of weeks. There’s plenty of swell kicking around, with moderate wave energy (587) kicking off Thursday, but the wind is just relentless. From Thursday July 9th all the way through July 20th, it’s constant cross-shore wind out of the ENE, blowing 30 to 45 km/h. That leaves the ocean lumpy and choppy, and the surf is just poor. The swell hangs between 2 ft and 3 ft from the ENE with a short period of 7 to 8 seconds. There’s energy there but it’s a mess. For a beach-and-reef setup like this, it’s honestly more interesting for kite surfing than paddling. The water temp is about 79°, which is pretty normal for the time of year.
Now, right at the tail end, around July 21st and 22nd, something shifts. The swell swings around to the east and turns into a very long period groundswell, hitting 15 to 19 seconds. The energy really jumps up to 1668 on the morning of the 21st—that’s strong. The height is only around 4 ft to 5 ft, but with that period, it’ll have some serious push. The catch is the wind is still cross-shore from the ENE at 30 km/h. It’s only a marginal call with questionable tides, but for the expert crew, that long-period easterly groundswell could draw some lines. It’s far out though, so it’s just a glimmer. After that, it fades right back into the same old drifty pattern.
So there’s no real standout here. That last little window is the only one worth half a look for the experienced surfers, and even then it’ll be a fight with the wind. Things can always change.
Rusty out.

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.
