The Lowdown

Alright mates, let’s break it down for ADs/Doubles. Rusty’s on the mic.

Honestly, the first look is a bit of a downer. From Sunday the 23rd of August all the way through to Saturday the 5th of September, the trade winds just won’t quit. It’s howling from the NE to ENE at 15 to 25 mph, and it’s almost always cross-shore or cross-onshore. That breeze is going to chew the surface up into a lumpy, choppy mess. The swell is there – we’re seeing some solid 6 to 8 ft days on the 25th of August and again on the 2nd of September – but with a short, weak period of just 7 to 8 seconds, the waves will be all over the place. The energy is there (moderate to strong), but you’d be fighting a losing battle for any kind of clean ride.

But then, just when you’re about to pack it in, we get a real cracker on Monday the 7th of September. That morning, the wind finally lays down. It switches to a light NNE at just 6 mph and turns cross-offshore, which is the magic ingredient for a clean face. The swell drops to a manageable 6 ft from the ENE, with a 10-second period – a proper, lined-up groundswell. The conditions are described as clean and excellent for experienced surfers. This is your session. It’s the only real standout in the whole 16-day window. Just be aware that crowds are likely here, so plan your paddle-out accordingly.

Water temp is about 81°, which is pretty normal for this time of year.

So here’s the plan: sit through the chop for the first ten days or so. Be patient. Your best bet is without a doubt Monday morning, the 7th of September. That’s the one.

Rusty.

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.
