The Lowdown

Alright, this is Rusty, and I’ve got a look at the outlook for A-Ds-Doubles. Let’s be straight up – it’s a pretty grim run for the most part, but there’s a real wildcard waiting for us if you’ve got the guts.

The water temperature here is sitting at 80°, which is right around normal for this time of year, so nothing weird going on there.

The first half of the window is a write-off. From Sunday the 9th all the way through to Saturday the 15th, we’ve got a solid week of poor conditions. The wind is a persistent fresh cross-shore, often from the ENE, just trashing the surface. The swell is a mixed bag of short-period windswell, mostly under 8 seconds, with a combined energy that fluctuates but is mostly in the moderate range (between 400 and 900). It’s lumpy, choppy, and frankly, not worth paddling out for. Even the long-period S and SSW pulses that show up on the 11th, 12th, and 13th are hampered by the wind, so they’re no good for riding.

Now, Sunday the 16th is the standout. The morning sees a solid 12 ft swell from the ENE, with a period of 13 seconds. The wind is a cross-offshore breeze from the NNE at 19 mph, which is a massive positive – it should be clean. Later in the day, the swell jumps to 15 ft from the same direction, with the wind shifting to a cross-offshore from the N. The combined energy rockets into the strong range (4579 and 6251). This is a serious groundswell, and for a spot like this, it’s going to be a heavy, powerful wave. But listen – this is for experts only. Over 8 ft, and especially at 15 ft, it’s a big, dangerous wall. Beginners need to stay well clear. The shape should be good for those who can handle it, and the low crowds (often) mean you might have a few sets to yourself, but don’t bank on it being empty.

After that, it’s back to poor conditions for the rest of the run. Monday the 17th through to the end of the window on the 24th is mostly cross-shore wind and messy, short-period swell, with combined energy levels dropping back into the moderate range. There’s nothing else worth chasing in that second week.

So, in short: a long, flat, windy gap until the 16th, then one big, clean, heavy day for the experienced crew. After that, it’s back to the waiting game.

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.
