The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s coming up for ADs/Doubles.
Alright, straight up – the next couple of weeks are a bit of a mixed bag, and honestly, there’s a fair bit of waiting involved. The first proper surf worth talking about doesn’t really show until the second week, so you’ve got a long stretch of nothing much before that.
For the first week, from Sunday the 9th right through to the end of the week, it’s pretty much all on the nose. The wind’s howling out of the ENE at 18 to 22 mph, cross-shore, and it’s creating lumpy, messy conditions. Swell is there, but it’s not doing you any favours with short-period stuff around 7-8 seconds. The combined energy is moderate (439 to 600 range), but it’s a write-off. The water temp is sitting at 80°F, which is about average for the time of year, so no surprises there.
The standouts in this entire outlook are a couple of days in the second week where the swell gets big, but only for the experienced crew. On Sunday the 16th, the swell jumps to 12 ft from the ENE, with a period of 12-13 seconds. The wind swings around to a cross-offshore from the NNE and N at 18 mph, and the comment says it’s clean. However, the wave energy is massive (5720 and 3534), and it’s flagged as too big for this break. This is expert-only territory – heavy, powerful, and not for the faint-hearted. The period is long enough to get some good shape, but at that size, it’s going to be a beast.
Then, on Sunday the 23rd, you’ve got another big one. Swell of 10 ft from the ENE, period around 8 seconds, and again, it’s flagged as too big for the break. The combined energy is strong (1665). The wind is still cross-shore from the ENE at 22 mph, so it’s going to be lumpy and messy despite the size. This one is also only for experts.
Other than those two days, the rest of the second week is a mix of small, weak swells or still-too-big conditions with poor wind. The only other day that might be worth a look is Monday the 18th, when the wind drops right off to a light breeze from the SE at 6 mph, blowing onshore, but the swell is tiny at 2 ft from the S with a 13-second period. The energy is low (268), and it’s marginal. Not something to get excited about.
So, the bottom line: if you’re an expert and want to test yourself, Sunday the 16th is your best bet – it’s the standout for size and clean conditions, but be prepared for a serious session. For everyone else, this 16-day window is a long wait. The crowds here are listed as “often,” so on those big days, you might have company, but it’s more about the risk than the crowd.
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.

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.
