The Lowdown

Alright, let’s get into it. Things are looking pretty grim at ADs/Doubles for the next week or so. The water’s sitting at 81°, which is pretty much normal for this time of year, so no surprises there.

We kick off on Wednesday afternoon the 26th of August with a weak little 2ft south swell, but the problem is a fresh cross-shore wind from the ENE at 22 mph is wrecking it. It’s lumpy and messy. Honestly, not worth paddling out.

Thursday the 27th has a bit more size in the morning – 4ft from the south with a long 17-second period, and the energy is moderate (1049). That’s a decent groundswell, but again that cross-shore wind is blowing hard and the conditions are just lumpy. The afternoon drops back to 3ft. Not good.

Friday the 28th stays small and messy, same story. Saturday the 29th jumps up to 7ft but it’s coming from the east-northeast with a super short 7-second period, and the wind is a strong breeze at 25 mph. That’s just a wall of chop. Kite surfers might get a kick out of it, but for a paddle surfer? No thanks.

Sunday the 30th through to Tuesday the 1st of September, we’ve got swell around 5ft to 7ft, still from the east-northeast, still short period, still cross-shore winds. The energy stays moderate (up to 1001), but the quality is poor. It’s just messy.

Wednesday the 2nd and Thursday the 3rd of September are more of the same – 6ft to 6ft, short period, cross-shore winds. There’s a slight improvement on the Thursday morning with a moderate breeze down to 16 mph, but it’s still a cross-chop. Marginal at best.

Friday the 4th and Saturday the 5th of September see the wind ease a little – light to gentle breezes – but the swell is still short-period and onshore or cross-onshore. The surf is still poor, with energy dropping to moderate-low (490). Not a standout.

Then we get a glimmer. Sunday the 6th of September morning, the swell switches to a 3ft SSW groundswell with a very long 17-second period. The wind goes light and onshore from the ESE at 6 mph. The conditions are marginal, but that period is proper. Monday the 7th of September morning keeps that 3ft SSW swell with a 15-second period and light cross-on winds. The energy is moderate (699). This is the best the outlook gets – clean enough for a patient surfer to pick off a few long lines, especially if the tide works. But it’s small and inconsistent.

After that, Tuesday the 8th through Thursday the 10th of September, it’s back to poor conditions with short-period east-northeast swells and strong cross-shore winds. Not worth it.

So, the standout is the window from Sunday the 6th to Monday the 7th of September. That’s the only real chance for a clean wave, even if it’s small. Everything else is a write-off.

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.
