The Lowdown

G’day, I’m Rusty, and I’ve been watching A-Ds-Doubles closely. The next two weeks are gonna test your patience. The water’s about 81°, which is normal for this time of year. But the wind is the story here—constant cross-shore and cross-onshore breezes from 19 to 28 mph, making things lumpy and choppy for days. No clean, glassy windows in sight for a long time.

The swell is mostly from the ENE, running 5 ft to 7 ft, with short, weak 6 to 8 second periods. The combined energy is moderate, sitting between 465 and 923. Plenty of waves, but they’re gonna be messy and sloppy. Not worth the paddle.

On the 2nd of September, we get a little change—swell switches to the south at 3 ft, but with a very long 16-second period and energy up to 850. The wind is still cross-shore and fresh, so the report calls it poor. That long period groundswell is better for a point or reef, not this beach setup. It’s a tease.

By the 6th and 7th of September, the swell jumps to 8 ft to 10 ft from the ENE, still short period at 8 seconds. The combined energy is strong, hitting 1046 to 1477. But the cross-shore wind is strong and messy—24 to 28 mph. This is getting too big for beginners, and the wind will ruin it for everyone.

Then the standout window arrives: Tuesday the 8th of September through to Thursday the 10th of September. Swell is pumping 8 ft to 12 ft from the ENE, with the period stretching to 9 or 10 seconds on the 8th, and the combined energy is massive—1586 to 2523 (very strong). The wind eases to a fresh 19 mph cross-shore. The forecast says “wind and tide favorable” but also warns the swell is predicted to be too big for this break. This is an expert-only affair—big, powerful, and demanding. Best on offer, but only for the brave.

After that, the surf fades fast. By the 12th and 13th of September, we’re back to 4 ft to 6 ft from the ENE, short period, weak energy. Winds finally go light—down to 6 mph—but it’s cross-on or cross-shore, and the wave quality is marginal or poor. The run is over.

So the real standout is the 8th to the 10th of September. Big, powerful ENE swell, very strong energy, and the wind finally cooperating for a clean-ish cross-shore. For experts only due to the size. That’s your moment.

If you’re a kite surfer, the cross-winds and lumpy conditions from the 6th to the 7th might actually be fun. For the rest of us, it’s a lot of waiting.

Stay salty.
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.
