The Lowdown
Alright, Rusty here. Let's break down what we've got in feet and old money.
Honestly, it’s a grim run for ADs/Doubles. For the first week and a half, the wind is howling out of the east-northeast and it’s ruining everything. You’re looking at about a 10-day stretch where you just don't bother. The water’s around 81°F, which is dead average for this time of year, so no worries there. It’s all about that wind.
The first real sign of life isn't until Thursday the 27th of August. That morning we get a 6ft swell out of the east with a very long 18-second period. That’s real groundswell, with energy reading 2310 (strong). That kind of period gives you good, lined-up waves and longer waits between sets – nice for this point. But the wind is still rubbish, a fresh 30 km/h cross-shore creating lumpy conditions. It's not clean, but it’s the best thing in this whole forecast.
That east swell holds through the afternoon at 6ft and into Friday morning (28th of August) at 6ft. The wind drops a little on Friday afternoon to a moderate 25 km/h, still cross-shore, which might take the edge off the chop. This is your window. Expect company too – this spot is often packed. The east swell lines up well with what the break likes.
After that, it falls apart again. Saturday and Sunday (29th and 30th) bring back the cross-onshore wind. The swell stays between 5ft and 10ft, but it's messy. That Sunday push of 10ft from the east-northeast is no good with the wind on it – anything over 8ft is for experts only, and with the chop, it’s a washout.
So, mark your calendar for the 27th and 28th of August. It’s not perfect, but it’s the only game in town with some proper east swell energy. The rest is 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. 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.
