The Lowdown
Alright, this is Rusty. Let's get into it, right here, right now.
The outlook for this spot is a real mixed bag. We've got a rough road ahead before we see anything worth paddling out for. The immediate forecast is a write-off: strong side-shore winds, lumpy conditions, and no quality on offer. This poor spell stretches from now through to the end of August and well into the first week of September. You're looking at a serious dry spell of about a week with absolutely nothing to recommend.
The first glimmer of hope might come around Monday, September 7th, but honestly, it's still marginal. Winds are still fresh and side-shore, making things choppy. The size starts to pick up to around 6 to 7 ft from the ENE, but the quality just isn't there.
Hang in there, because the standout window kicks off on Wednesday, September 9th. The afternoon sees a proper pulse of groundswell. We're talking 8 ft from the ENE with a long 12-second period and strong combined wave energy of 1852. The wind is moderate and side-shore, so there'll be some texture on the face, but this is the most promising day of the whole run. The water is a warm 81°F, which is about average for the time of year – all good on that front.
Then things get interesting for the experts. On Thursday, September 10th, the swell builds even further. The afternoon pushes to a solid 10 ft from the ENE, with light side-onshore winds. This is big, powerful, and honestly, at over 8 ft, it's strictly for experienced surfers. The break (A-Ds-Doubles) is exposed to this energy, and that long-period groundswell will be powerful. That light wind is a big positive, keeping things clean, but the sheer size makes it a serious proposition. Friday morning the 11th keeps that 10 ft size, but the wind goes light offshore from the ESE. The period drops a touch to 9 seconds, but the energy is still massive. This is another day for the big dogs only.
If you're a kite surfer, all that lumpy, strong-wind chop from the first week and a half will look much more appealing than it does to a paddle surfer. For the rest of us, the second week offers the only real hope, with that Wednesday afternoon to Friday window being the best on offer.
Stay patient.
Rusty.

Information about the ADs/Doubles Surf forecast

A general guide to surfing at ADs/Doubles can be found by selecting the local surf guide option on the grey menu.

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.
