The Lowdown
Alright, Rusty here. Let's break down what's ahead for ADs/Doubles.
For the next week or so, it's going to be a real battle with the wind. It's mostly blowing cross or cross-onshore from the ENE and NE, keeping the surface lumpy and messy. There's plenty of swell hitting, but it's short-period, 8-second windswell that just churns things up. The combined energy is pumped up, over 1000 (1194) at times, but it's not doing you any favors with the wind against it.
But we've got a clear, clean window to target. Wednesday July 29th is the morning to be in the water. The wind swings around to the south and goes glassy at just 3 mph. That's a game-changer for this exposed break. The swell is a powerful 8ft from the ENE with a 10-second period, giving it good shape. With that energy (1695 in the water) and those glassy conditions, this is your best shot. It's a ripper for experienced surfers. Just know this spot can get crowded, so you won't be alone.
After that morning, the wind shifts onshore in the afternoon, so get your session in early.
The following week is more of the same story: messy cross-shore winds and weak, short-period swell. The energy drops away, falling under 500 (289) and even 333 by the 7th and 8th of August. There's a tiny glimpse of something on the 9th of August with a 2ft, 17-second SSW groundswell, but it's weak (414 energy) and the wind is onshore again. The water is 80°F, which is right on the money for this time of year.
To sum it up: save your energy for that Wednesday July 29th morning. That's the one.
Rusty.

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.
