The Lowdown

G’day, Rusty here. Look, I’ll be straight with you—this 16-day stretch for ADs/Doubles is a real mixed bag, and honestly, most of it’s a write-off. The water’s sitting at 80°, which is pretty much spot on for this time of year, so no surprises there. But the wind? It’s a relentless cross-shore or cross-onshore mess from the ENE for the first week and a half, with gusts up to 25 mph, pumping moderate to strong wave energy (values like 831, 1049, and even 1807), but it’s all lumpy, choppy, and just plain ugly. There’s a solid 7 ft to 10 ft of short-period ENE swell (7-8 seconds) rolling through from Monday 31 August right through to Friday 4 September, but it’s completely blown out—zero quality. Then from Saturday 5 September to Monday 7 September, the swell stays around 8 ft to 8 ft with a longer period of 13 seconds, which is better energy (values up to 2727), but the wind’s still cross-shore out of the ENE at 19 mph, so it’s marginal at best.

Now, the one standout that might save this run is Monday 7 September afternoon. The swell drops to 8 ft from the ENE at 11 seconds, still a bit long-period for a beach break like this, but the wind swings to a light N’ly at 9 mph, going cross-offshore. That’s clean—gentle breeze, clean conditions. The energy’s still strong at 2077, and while it’s a bit big for beginners, intermediates should find some fun if they work the tide. The rest of the second week drops off fast: Tuesday 8 September sees a 5 ft NE swell with a weak 9-second period and cross-on wind, then by Wednesday 9 September it’s back to messy 8 ft ENE junk. From Thursday 10 September onward, the swell fades to 5 ft and below, with periods as short as 7 seconds or as long as 16 seconds, but the wind stays cross or cross-on, and the energy drops to weak (248 to 469). There’s a gap of little to no surf from about 10 September to the end of the forecast, with only tiny 2 ft to 3 ft leftovers. The only time worth paddling out is that Monday 7 September afternoon—don’t hold your breath for anything else.

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.
