The Lowdown

Alright, let’s get real about ADs/Doubles. The next couple of weeks are a rough stretch.

The first week, from Wednesday, August 19th through the weekend, is basically a write-off. The wind is all wrong – strong cross-shore – and the swell is short-period slop. The combined energy is just moderate, but the wind chops it all up. Not worth wetting a wetsuit.

We get a little tease on Thursday morning, August 27th, with some longer period south swell, but the wind is still cranking cross-shore, so it’s just lumpy and unrideable.

The one true highlight, and the only serious window, is Tuesday, September 1st. We’ve got a major swell from the east pushing 10 feet, with a period of 13 seconds – that’s real groundswell energy. The combined energy reading is a massive 3039 – that is strong juice. The catch is the wind is still cross-shore at 30+ km/h, so it’ll be bumpy on top. At that size, it’s strictly for experts only. Crowds are likely, because everyone with the skills will be out.

After that pulse, the swell backs off, but the wind stays relentless, so the rest of the forecast looks like blown-out junk. For most surfers, I wouldn’t bother planning around this. The whole run is so cross-shore and choppy that it’s really only interesting for the kite boarders. But, you never know – forecasts can change.

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.
