The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for A-Ds-Doubles over the next couple of weeks. Gotta be straight with you – this forecast is a bit of a slow burner. There’s a big ol’ gap at the start here with nothing worth paddling out for.

The Overall Picture

For the first week, it’s pretty much a write-off. We’re talking days of onshore cross-shore winds from the ENE, making a mess of things. The surf is there in size, but the quality is just plain poor. You’re looking at lumpy, choppy, blown-out conditions. Honestly, from Tuesday the 15th right through to Tuesday the 22nd, it’s a no-go. That’s over a week of straight poor conditions. Even when the swell jumps up, the wind just kills it.

The Turnaround (Week Two)

Now, things start to look interesting towards the end of the month. The first real glimmer of hope comes on Wednesday the 23rd of September. The wind finally drops right out. The morning still has some cross-shore bump, but by the afternoon we get a light cross-offshore breeze from the WSW. The swell is a solid 8ft from the E, but with that clean wind, it’s looking good. This is for experienced surfers only though – that’s a heavy wave for a beach break, and the combined energy is pumping at (1579).

The Standout

If you’re going to pick one day, make it Saturday the 26th of September. This is the pick of the forecast. We’ve got glassy conditions – absolutely dead flat wind – in the morning, with a 8ft ENE swell. That’s a big, clean wave. It’s still going to be a handful, so this is for the advanced crew only. The break (A-Ds-Doubles) is exposed, so that clean swell is gonna wrap in nicely. The combined energy is strong (1034). Expect crowds here though, because when this spot turns on like this, everyone knows about it. The afternoon holds similar glassy conditions too.

The Rest

Thursday the 24th of September is another one for the big-wave chargers, with 10ft E swell and clean cross-offshore wind, but it might just be too big and powerful for this break. Friday the 25th is a step down with lighter winds but cross-onshore, so not as clean. By Sunday the 27th, the swell drops to a more manageable 6ft, and the morning has light cross-onshore bumps, but the afternoon turns glassy again with a clean 3ft SSW groundswell. That late-period groundswell will be wrapping in nicely.

Final Word

The first week is a total bust. Save your energy. The second week, specifically the 23rd through the 26th, has some real potential for the experienced surfers. It’s a promising stretch, but we’re a week out, so keep an eye on it.

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.
