The Lowdown

Alright, Rusty here. Let’s take a look at what’s going on.

Honestly, mate, this stretch is a tough one. We’ve got a full 16-day window, but right from the get-go, it’s looking pretty grim for a proper paddle session. The first real chance of anything surfable doesn’t even show up until later in the period, and even then, the conditions are far from ideal.

For ADs/Doubles, we’re looking at a lot of cross-shore and cross-onshore wind. Tuesday the 8th has some swell – 6ft at 11 seconds from the ENE - but that wind is a 12 mph cross-shore, and the overall wave energy is strong at 1588 (moderate energy). The water temp is 81°F with a tiny anomaly of +0.2°F, so pretty much bang on average for this time of year. The forecast calls it “marginal,” and I’d agree; not a good one to chase.

We hit a real dry spell from Wednesday morning the 9th all the way through to Sunday the 20th. Over a week and a half of small, junky waves with persistent moderate to fresh cross-shore winds and a lot of wash-through energy. There are a few spikes in swell size – some 6ft and even 7ft days around the 17th and 18th – but the period is short (8 to 9 seconds) and the wind is a messy cross or cross-on, all rated as “poor surf conditions.” For the intermediate surfer, these days are more about frustration than fun. A 7ft wave with a short period and cross-shore wind isn’t worth suiting up for.

Now, we do get a couple of interesting moments in the second week. On Wednesday the 16th afternoon, there’s a 3ft wave but from the SSW with an 18-second period – that’s a very long period groundswell! The energy reading is 969 (moderate). The problem? The wind is still cross-on from the ENE at 16 mph. A long-period swell like that at a beach break can be really hard to ride because it tends to close out fast. It’s a tease, not a goer.

The only window that might raise an eyebrow is late on Friday the 18th afternoon. We’ve got 6ft swell from the E at 9 seconds, with a combined energy of 1016 (strong). Still, the wind is a fresh 22 mph cross-shore, so it’s going to be lumpy and choppy. The forecast calls it “marginal,” not “poor,” which is an upgrade, but it’s still not clean enough to call a standout. If the wind dropped, it would be a different story.

Bottom line: there are no real standouts in this 16-day window for ADs/Doubles. The wind is relentless, and the swell quality never aligns with the right conditions for a great paddle session. If you’re a beginner, steer clear of the bigger days (over 5ft) – it’s not worth it. The complete lack of consistent, clean conditions is a real bummer. Given the profile of this break, a blank run like this is just how it goes sometimes. Forecasts can shift, but right now, I’d leave the board at home and maybe go for a run instead.

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.
