The Lowdown

Hey, Rusty here. Let’s run through what’s happening at ADs/Doubles. Honestly, the first week and a half is a total bust. There’s a big gap of poor, messy conditions right from the start until late July. The wind is stuck cross-shore or cross-onshore from the ENE and NE, blowing 15 to 22 mph, keeping the surface lumpy and chopped up. The swell hangs around waist to chest-high but with a short period – 7 to 8 seconds – so it’s weak and junky. A few days have some long-period SSW groundswell, but those are tiny – 2 ft to 3 ft – and get torn apart by the wind. For 9 days or so, there’s nothing worth paddling out for. Even on the 22nd, when we see a "marginal" call, the wind’s still cross-shore and the swell’s only 5 ft from the ENE with a short 7-second period. Not clean, not inviting.

It’s not until Monday the 27th that we get a glimmer. Swell swings around to the east with a 15-second period – that's real groundswell – and the combined energy hits 971 (moderate), building to 1018 (strong) by afternoon. Winds finally drop to a moderate 12 mph cross-shore from the NE. The swell’s only 4 ft to 4 ft, but with that long period, the waves should have some decent shape and power. This spot runs best on an ESE swell, and we’re getting east, so it’s a fair match. Crowds are often around, so don’t expect to surf alone. Water temp is 79°F, about normal for the season.

The real standout is Tuesday the 28th. The morning brings a solid 7 ft swell from the ENE with a 13-second period and energy of 1684 (strong). That’s the biggest and most powerful day of the whole outlook. Winds are still cross-shore from the ENE at 15 mph, moderate breeze, so not perfectly glassy, but at that size the reef will be pumping. This is strictly for experts – 7 ft is well over 8 ft, so only the skilled need apply. Crowds are likely, so be ready for a packed lineup. The afternoon keeps similar size at 7 ft with 12-second period and energy of 1544, still serious waves. That Tuesday is easily the best day on offer, even if the wind isn’t pure offshore. Everything before that is a long, flat, blown-out wait.

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.
