The Lowdown
Alright, Rusty here. Let’s break it down. The first week for ADs/Doubles is pretty grim – a long stretch of cross-shore winds, messy chop, and poor surf. Water temp is around 26.5°, pretty normal for this time of year.
The only real highlight is the morning of Monday, July 29th. You’re looking at a big 9.8ft ENE swell, with a clean cross-offshore breeze from the north at 16 mph. The wave energy is huge (2114), so this is serious power. That’s expert-only territory, and this exposed beach break will be handling it. It’s more than a week away, so stay tuned. The afternoon gets a bit lighter and cross-on, so the early session is the one.
After that, it’s back to a lot of cross-shore winds and lumpy conditions from Thursday, July 30th all the way through the first week of August. There’s a marginal moment on the morning of Tuesday, August 6th, with gentle cross-shore wind and about 5.9ft swell, but nothing to get excited about. Wave energy drops hard later on, down to 370 by Friday the 7th, so the second week really fizzles.
One solid morning on the 29th for the experienced crew, and a lot of time to wait for the next one.

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.
