The Lowdown
Alright folks, Rusty here. Let's take a straight look at what's coming for ADs/Doubles over the next couple of weeks. Truth is, the pattern is mostly a bummer, with just one or two windows where it might clean up a bit.
Right from the start, the first week is a complete loss for decent surfing. We've got a solid 25 mph wind from the ENE hammering the water, and that just destroys the surface. The combined swell energy numbers are bouncing around in the moderate to strong range – from 952 to 1195 – but with that much cross-shore wind, it's just a mess of chop and cross-chop. Not worth looking at.
The water temp is sitting around 80°F, which is about normal for this time of year, so no surprise there.
By Friday the 25th and into the weekend we get a slight improvement, but it's still only marginal. The wind drops a notch to a fresh breeze – still cross-shore though – so the surface stays lumpy. Swell heights start to build a little, from about 4ft to 7ft on the 27th and 28th, and the energy really shows up – we're talking strong numbers, like 1183 to 1399. The period stretches out to 13 or 14 seconds on that east swell, so there's some groundswell in there. But with cross-wind on ADs/Doubles, it's still not going to give you the clean lines you want.
The real standout in this whole outlook looks like Tuesday the 28th. That's when we finally get a shift to a cross-offshore breeze from the NE, around 15 to 19 mph. That is clean. The swell hits 7ft with a 12-second period from the E/ENE, and the combined energy is pumping at 1525. That's strong, powerful surf. Now, 7ft is getting into expert territory – not one for beginners – but for the experienced crew, this is your best shot. That clean cross-offshore wind should give you some really workable, groomed waves. Just know that crowds are often here, so you won't be alone.
After that, Wednesday the 29th still has clean cross-offshore wind, but the swell drops to 6ft and the period drops to 11 seconds, with the energy down to 991. It's still surfable, but the Tuesday session is the clear winner.
Heading into the first week of August, things get messy again. The wind switches back onshore or cross-shore, with a lot of ENE wind, and the swell drops right off – down to 2ft or 2ft at times. The combined energy drops way low, even below 200 (196), which is weak. There's a chance on Monday the 5th with a 7ft swell and a 12-second period, but with a fresh cross-shore breeze and lumpy conditions, it's still only marginal.
So to sum it up: the surf is mostly poor to marginal across these 16 days. The only real standout is Tuesday afternoon the 28th of July, when the clean cross-offshore wind matches up with a solid 7ft east swell. Everything else is a fight against the wind and chop.
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.
