The Lowdown

Alright, Rusty here. Let’s be straight with you – this stretch is a tough one. We’ve got a full 16-day window, but honestly, the first week and a half is a write-off for quality surfing at A-Ds-Doubles. The wind is just relentless out of the ENE, and it’s blowing hard. You get cross-onshore and cross-shore conditions day after day, with a lot of chop and mess. The combined wave energy is there – we’re seeing moderate to strong energy values – but that energy doesn’t matter when the wind kills it. For the first week, you’re looking at poor surf conditions or marginal, questionable tide conditions. The wait is real.

The first sign of life comes on Saturday the 14th of September. The morning shows a slight let-up. The wind drops to a light breeze from the NE, only 6 mph, and it’s cross-shore. The swell drops to 4 ft from the ENE, with a short period of 7 seconds. Combined energy is weak. It’s still only a marginal forecast, but with the wind this light, you might find a cleaner, less choppy surface. It’s a glimmer, not a standout. The water temp is 81°, which is about average for this time of year, so no surprises there.

Now, the real standout, and the only true promise in the whole outlook for me, is the final few days. We’re looking at Wednesday the 16th and Thursday the 17th of September. The swell direction shifts to the SSW, and the period jumps to 17–19 seconds – that is proper long-period groundswell. The height drops though, to only 3 ft to 3 ft. The combined energy shows moderate values, which is decent for such a small swell. This kind of long-period, clean swell is usually best suited for a point or reef setup, and A-Ds-Doubles is an exposed break. It can be inconsistent, so don’t expect a wall of waves. But the wind is still a problem, staying cross-on or cross-shore from the ENE at 12–16 mph, so it won’t be glassy. It still reads as marginal, but this is the best on offer – a small, clean-lined, long-period groundswell. It’s promising, but hold your expectations.

For the bulk of this forecast, honestly, look elsewhere. That string of days from the 2nd to the 13th of September is hammered by onshore wind. It’s more a kite-surfing setup than a paddle session. But keep an eye on the end of the window – that small, long-period SSW swell is the only real chance at a wave, even if it’s a gamble with the wind.

Rusty, signing off.

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.
