The Lowdown

Right, let's talk about ADs/Doubles. Straight up, this is looking like a tough run for the next couple of weeks. There's a lot of swell energy on the cards, but the wind is the villain here, making a mess of things more often than not.

The forecast kicks off on Friday, 31 July, with a strong ENE breeze blowing cross-shore. We've got a solid 6 ft of east swell rolling in, with a short period of 8 seconds, and the combined energy is up around 777, so there's plenty of push, but it’s all cross-chop and messy. Honestly, it’s not looking good for a paddle. For anyone thinking of towing or kiting, that 25 mph wind might make it interesting, but for a surfboard, leave it.

Saturday, 1 August, the swell jumps right up, peaking at 12 ft on the morning with a massive 1572 combined energy. But that wind is still a strong, cross-shore ENE breeze at 28 mph. That's expert-only territory if you’re brave enough to tackle the bump, but the wave quality is listed as poor. It stays big and messy right through Sunday, with 8 ft swell and the wind still howling.

We get a slight break in the wind speed come Monday, 3 August, dropping to 19 mph, but the swell is still a chunky 6 ft and cross-shore. The waves are lumpy and not inviting.

Into the second week, things start to change shape. On Tuesday, 4 August, the period stretches out to 11 seconds, which is a better sign, and the swell drops to a more manageable 5 ft. The wind is lighter too, at 12-16 mph, but it's still cross-shore. The surf is still just marginal, with a combined energy of 756. It’s cleaner than the previous days, but not quite good enough to call a standout.

The rest of the week from Wednesday 5 August to Sunday 9 August is pretty bleak again. Swell sizes bounce around from 3 ft to 7 ft, but with short periods (6-8 seconds) and moderate to fresh cross-shore winds, it’s just a consistent run of poor-quality, lumpy surf.

Now, here’s where it gets interesting. On Monday, 10 August, we see a completely different swell pop up. A long-period groundswell from the SSW, 16 seconds, sneaks in at only 3 ft. The combined energy is still 824, so there’s some grunt in that long period. But the wind is cross-onshore and choppy, killing the potential. For a spot like ADs/Doubles, a long period SSW groundswell is normally a beautiful thing, but with the wind on it, it’s just a tease.

The same story plays out with another SSW groundswell on Thursday, 13 August, and Friday, 14 August. We get 2 ft swell with a period of 16-18 seconds, and the wind finally drops to a light to gentle breeze. On Friday afternoon, conditions are marginal but closest to clean we’ve seen all period. The wave energy is 546, so there's enough there for a longboard if you pick your moment. It’s not a standout, just the least bad option in a rough two weeks.

Honestly, if you're looking for a highlight, Friday the 14th of August afternoon is your best shot. The wind will be light cross-onshore and the swell is clean and long-period. It'll be small, maybe only 2 ft, but it's the only time in this whole outlook the wind is genuinely light. For a longboard or a SUP, it could be a glassy little session.

For the rest of the time, the ENE wind is relentless and cross-shore, turning what could be decent waves into chopped-up mess. There's no real window of excellence here. The water temperature is about average for the time of year, nothing unusual to report.

Keep an eye on the charts, this run won't last forever.

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.

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.
