The Lowdown
Right then, let’s have a look at what’s on the cards for ADs/Doubles.
Honestly, it’s a tough stretch ahead. The first week or so is riddled with lumpy, cross-shore winds and messy conditions. The wave energy is significant, but it’s all dressed up with nowhere to go thanks to the wind. The combined swell energy is up around 2500 (2575) on Saturday the 5th, but with a fresh, cross ENE breeze at 22 mph, it’s going to be chopped up and bumpy. The swell is a solid 8ft at 13 seconds from the ENE, which has some power, but it's not going to be any fun to paddle out into that onshore chop. It’s a beach-and-reef setup, and with these winds, this looks more interesting for the kite surfers than paddle surfing for a good few days.
That poor run of wind and chop drags on through the following week. We see the swell dip a little, but the wind stays cross or cross-on from the ENE or NE, mostly in the 15 to 22 mph range. The conditions are labelled as poor or marginal right the way through to the middle of the month. A slight shift on Tuesday the 8th with a lighter S wind and 6ft swell looks a bit less aggressive, but it’s still cross-on and choppy. There’s just no clean window to speak of.
Now, there is a flicker of something different around Wednesday the 16th. A long-period groundswell shows up from the SSW with a 21-second period on Tuesday the 15th, but it's tiny at 3ft and cross-on. Then on Wednesday the 16th, we see it again from the SSW at 3ft with an 18-second period. The combined energy jumps to 1119, and importantly, the wind is cross-shore from the ENE at 16 mph. It’s a moderate breeze, so it’ll be a bit lumpy, but that deep, long-period groundswell will wrap in and offer some clean, powerful lines at the right tide. This is the one true standout, but it’s a full week and a half away, on Wednesday the 16th and into Thursday morning. It’s promising, but long-range and less certain.
For the rest of the outlook, through to the end of the 16 days, it’s back to strong ENE winds in the 25 mph range, cross-shore and messy, with weak, short-period windswell. It’s a bleak run with a couple of days of hope right in the middle.
Stay patient, boys. Wednesday the 16th has a pulse of clean, long-period energy if the wind plays ball. Until then, it’s a struggle.

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.
