The Lowdown

Alright folks, Rusty here. Let's be straight with you – this is a tough stretch for surf at ADs/Doubles. We're looking at a 16-day window that's pretty much a write-off for quality waves. The forecast is dominated by a persistent, breezy onshore flow that's just making a mess of things.

The first real chance for a wave comes on Tuesday, the 4th of August, with a knee-to-waist high swell from the east-northeast at 5 ft. The period is a moderate 11 seconds, which gives it a bit of life, but the wind is blowing cross-shore at 12 mph. The combined wave energy is moderate at 673, but the text says "marginal surf forecast or questionable tide conditions." That's about as positive as it gets. The rest of that day and the next few are just "poor surf conditions" with the wind picking up, so don't get your hopes up.

The water temp is about average for the time of year, nothing weird going on there.

We do get a bit of a pulse from the south on Wednesday, the 12th of August. The swell is small, only about 3 ft, but the period is a very long 18 seconds. That's proper groundswell energy. The combined energy hits 1018, which is strong. The problem is the wind is still a messy cross-shore at 22 mph, so it's going to be lumpy and hard to read. It's a "marginal surf forecast" again, but that long period is a tease. For a spot like this, that long period groundswell might actually make the waves a bit too straight and close out, but if you're a keen surfer, it's the only thing worth a look in the whole period.

From the 14th onwards, the swell gets bigger, pushing 8 ft, and the wind just gets stronger. 25 mph, 28 mph, strong cross-shore and cross-onshore winds. At that size and with those winds, this is going to be a choppy, blown-out mess. That's kite-surfing territory, not paddle surfing. The wave energy is strong (over 1000 on some days), but the quality is zero.

So, the bottom line: there's a solid 16-day gap with no real quality surf on offer. The one standout, if you can call it that, is the morning of Wednesday, August 12th, with the long-period south swell, but it's a gamble. For the rest of it, you're better off waiting for the forecasts to change. It has to get better sometime.

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.
