The Lowdown

Rusty here again, giving you the lowdown in feet and miles per hour.

Right now, it’s a tough start. We’re looking at a solid run of poor conditions with no real surf to get excited about through the first week and into the second. The wind is mostly cross or cross-onshore from the ENE, and it’s blowing strong, creating lumpy and choppy seas. There are a few swells showing decent size, like the 12 ft to 13 ft stuff around the 15th and 16th of August, but the wind is a real killer – near gale force with messy cross-chop. For the first several days, there’s nothing I’d point you toward. It’s just not worth paddling out.

Things don’t really get interesting until we hit the end of the third week. The first real glimmer comes on the morning of Thursday, the 27th of August, at ADs/Doubles. The swell is coming from the E at a groundswell period of 17 seconds, which is that long-period juice we love. The combined wave energy is strong at 1712, so it’s got some serious weight. It’s pushing around 4 ft, which is solid for intermediate surfers. The wind is a light breeze from the E, making it cross-onshore but light enough that it leaves the surf reasonably clean. This is the standout session in the outlook – the cleanest you’ll find, with that long-period E swell wrapping in. The optimum direction for this break is ESE, so the E swell is close, and the water temp is 81°, which is about average for the time of year.

The afternoon of that same day and into the following days stays marginal. Periods are still long (16-17 seconds) and swell is in the 4 ft to 5 ft range, but the cross-onshore wind picks up again, making things choppy. If you’re chasing that Thursday morning window at ADs/Doubles, you’ve got your best shot. It’s not a guarantee this far out, but the ingredients are there.

Overall, there’s a long quiet spell at the start. Surf-wise, it’s pretty bleak until that final three-day window brings the long-period groundswell. That’s your target.

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.
