The Lowdown

Alright, let’s get into it. The truth is, ADs/Doubles is looking pretty average for a long stretch. There’s a huge gap at the start of the forecast with absolutely no decent surf – we’re talking day after day of messy, cross-shore slop and lumpy conditions that are hard to get excited about.

The first real chance we see something worthwhile is on Sunday, the 16th of August. The morning shows a bump in swell, about 8ft from the ENE, which is decent. The wind turns cross-off from the NNE, which is a big positive - it’ll clean things right up. The swell period stretches out to 11 seconds, giving it some real groundswell punch. This is a standout option for the whole outlook. The energy is strong (1892), so expect good push. Just remember, the crowds here can be an issue – it’s often busy for good reason. The water temp is about average for this time of year, nothing too unusual.

Sunday afternoon gets even bigger, with 10ft from the ENE and a near gale cross-off wind. That swell energy hits 2020 – very powerful, but the size and wind might be pushing the limits for anyone but experts.

After that, things get messy again. There’s another potential window on Monday, the 18th of August. It’s not a classic, but the morning shows a smaller 5ft from the NNE with a light onshore wind from the ESE. It’s marginal, but with the light breeze, it’s at least rideable, and the crowds might be thinner if you’re willing to hunt.

Following that, we see a long gap of cross-shore wind and lumpy conditions, with the occasional small SSW swell that never really lines up right. The energy is moderate at best. The period on those SSW pulses is long (15-18s), but the swell height is tiny – around 2ft to 3ft – so it’s not doing much for ADs/Doubles which is an exposed beach break. A long period, small swell on a beach break often ends up breaking straight and mushy.

There’s a glimmer way out on Saturday, the 22nd of August, with a 6ft ENE swell, but the wind remains cross, making it lumpy. The 26th of August shows another small S swell with a good period, but it’s all cross-shore and lumpy. Honestly, the quality across this whole run is poor.

Bottom line: Sunday the 16th morning is your best bet. It’s the only time the wind and size really align for clean, punchy surf, but be prepared for company. Everything else is a fight against lumpy cross-shore chop or just too small to really get your hopes up.

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.
