The Lowdown
Alright, Rusty here. Let me tell you about the surf outlook at ADs/Doubles, because to be honest, it’s a bit of a tough stretch.
The first few days of this forecast period aren’t what you’d call epic, but there’s a window to look at. The most promising moment across the whole 16 days is the morning of Wednesday, 29 July. We’ve got a solid 8 ft swell rolling in from the NE with a moderate 10-second period. The wind is a light 6 mph cross-shore, which will keep things cleaner than the rest of the week. The combined wave energy is moderate at 1135, and the offshore wind direction is NW, favorable for this break. It’s not a mind-blowing day, but in this stretch, it’s the pick. Be aware, crowds are often here, so expect company.
Things go downhill fast after that. From Thursday morning, 30 July, right through to the end of the first week, it’s a write-off. Strong to fresh onshore winds from the ENE, combined with choppy, messy conditions, make for poor surf. The swell sticks around 5 ft to 7 ft, but the energy is low and the period is short (8 seconds), so the quality is just not there. It’s not worth paddling out. Honestly, this setup looks more interesting for kite surfing than paddle surfing through this whole period, especially when the swell hits 10 ft on 1st and 2nd August with that same strong ENE wind.
Monday, 4 August sees a shift. The swell drops to 6 ft but the period jumps to 12 seconds, a proper groundswell from the ENE. The combined wave energy picks up to 1098. Wind is still a fresh 19 mph cross-shore, so it’ll be lumpy. Tuesday morning is marginal at best. Beyond that, from Wednesday, 5 August through Sunday, 11 August, it’s mostly a repeat of messy, wind-affected surf with heights ranging from 5 ft to 10 ft. It’s poor.
Then we get to the final days. Monday, 10 August and Tuesday, 11 August bring a completely different swell. The size drops right off to under 3 ft, but the period is a very long 15-16 seconds from the SSW. That’s all raw, long-period groundswell. The wave energy is moderate (between 737 and 921). The problem is the wind. Still a fresh to strong cross-shore from the ENE, which will chop it up. On a point break or reef, that long period might be a dream, but here at ADs/Doubles, it could break a bit too straight for a good ride. It looks more promising than the rest of the muck, but the poor condition call says it’s still not on.
Overall, the one real stand-out is Wednesday morning, 29 July. If you’re going to get wet in this period, that’s your best shot. The rest of the 16 days is a long, blank run with few redeeming features for a surfer.
Rusty.

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.
