The Lowdown

Alright folks, Rusty here. Gotta be straight with you – this outlook is a tough one. We’re looking at a long, painful stretch of poor conditions before a glimmer of hope shows up way down the line.

We’re starting with ADs/Doubles. The problem is the wind. We’ve got a persistent, strong cross-shore breeze from the ENE, blowing 18 to 28 mph, day after day. This is creating a lumpy, cross-chop that’s just ruining any chance of a decent wave. The combined energy is moderate, with values like 633 to 734, but the quality is zero. The swell is a mix of short-period, wind-affected stuff from the east, and some longer-period 16-18 second groundswells from the south, but the wind is so messy it doesn't matter. The water temperature anomaly is about average for the time of year, so nothing to write home about there.

This ugly run goes on and on. From Wednesday, August 26th, right through to Saturday, September 5th, it’s a solid 11 days of "poor surf conditions" – nearly every session is a write-off. The wind is just relentless. The swell height gets up to 8 ft around the 4th of September, but it’s with a 7-second period and strong, messy cross-shore winds. That setup is more interesting for kite surfing than paddle surfing.

Then, on Sunday, September 6th, we get a bit of a change. The wind eases, but the swell drops to 3 ft from the SSW with a 16-second period. The combined energy is still strong at 868, but the waves are tiny and the wind is still a strong cross-shore. It’s still not worth it.

Now, here’s the one that has my attention, even if it’s a long way off. Monday, September 7th. The wind finally swings offshore. Monday morning we get a light WNW breeze, and by Monday afternoon, it’s a clean, light offshore from the NW at just 6 mph. The swell is 4 ft from the SSW with a 14-second period. The combined energy jumps to 1269, which is a solid, moderate-to-strong energy. The report says "excellent surf conditions for experienced surfers," and I can see why. That long-period groundswell from the south will wrap in nicely, and with glassy offshore winds, ADs/Doubles will be clean and lined up. This is your standout. It’s a week and a half away, so don’t bank on it, but it’s the only real window of quality in the entire 16-day forecast.

After that, it goes back to junk. Tuesday, September 8th, the wind swings onshore again, and we’re back to stormy, choppy conditions with a 5 ft to 5 ft south swell, but it’s a washout. The rest of the forecast is more of the same – poor, messy, and windy.

So, the call is this: Wait for Monday, September 7th. That’s your one shot. Everything else is a write-off. The gap between now and then is a full 12 days of junk. Keep your eyes on that forecast, but don't get your hopes up too high.

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.
