The Lowdown
Alright, let’s talk about ADs/Doubles in feet and knots. I’m not gonna sugarcoat it – this forecast is a shocker. The wind is stuck on ENE, and it’s howling. For almost the whole 16 days, we’re looking at cross to cross-onshore wind, blowing 25 to 28 mph. That means the surface is going to be lumpy, choppy, and messy.
Right from the start on Saturday, August 1st, we’ve got serious swell size – 11 to 12 feet – and the combined wave energy is a massive 1674. But it’s all coming from the same direction as the wind (ENE), with a short 8-second period and a strong onshore breeze. It’s just a bumpy, blown-out mess. Not for surfing; more for the kite crew.
Things stay ugly through the first week. The swell hangs around 4 to 8 feet, but that ENE wind keeps blowing 18 to 25 mph. The waves will be weak and lumpy. Tuesday the 4th shows a bit of promise – the swell drops to about 5 feet, the period stretches to 11 seconds, and the wind eases to 12 mph. But it’s still a cross-shore. The best word for it is “marginal.” The break is fairly consistent, and crowds are often a problem here, so that Tuesday morning window is your only real chance.
After that, it falls apart. From the 5th onward, the swell drops away. We get some long-period groundswell from the SSW and S around the 10th to the 14th, with periods hitting 15 to 19 seconds, but the wind stays pinned on the ENE at 18 to 22 mph. That long-period energy with that cross-wind just turns the ocean into a washing machine. The energy stays moderate – between 282 and 774.
There is no perfect day here. The only half-decent window is the morning of Tuesday, August 4th. The swell will be about 5 feet from the ENE, the wind is the lightest we’ll see at 12 mph, and it might just be ridable. But keep your expectations low.
ADs/Doubles is a consistent break, so a run this bad is unusual. The forecasts can always flip, so don’t write the whole month off yet.

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.
