The Lowdown

Right, let’s have a look at what’s on the cards for ADs/Doubles over the next couple of weeks.

Truth be told, it’s a rough stretch. The whole 16-day window looks pretty bleak, with no standout days and a lot of sessions that will leave you frustrated. The first wave of any real size rolls in right from the get-go, but it’s a messy situation.

We kick off on Friday the 31st of July with a 10 ft easterly swell, 8-second period, and a strong 25 mph cross-shore wind. The energy is high (1361), but the wind is just tearing across the water, making it a lumpy, cross-chop mess. It’s basically a kite setup, not a paddle one. This continues into Saturday the 1st of August with a similar story: 12 ft of easterly swell, 28 mph winds and the same cross-chop. The water temp is about 80°, which is pretty average for this time of year.

Sunday the 2nd drops slightly to 8 ft, but the wind is still pumping at 22-25 mph from the ENE. The combination energy stays high (1241 to 1039), but the wind won’t let up. Monday the 3rd is still poor, with 6 ft and fresh cross-shore winds. The only glimmer of something a bit less aggressive comes on Tuesday the 4th of August morning, where the swell drops to 5 ft, the period stretches out to 11 seconds, and the wind eases to 12 mph. It’s still cross-shore, but the energy drops a bit (648). It’s only a marginal call, and the tide might mess it up, but it’s the least offensive option in the first week.

From there, it’s a long, dry gap. Wednesday the 5th through to Sunday the 9th of August sees swell bouncing between 2 ft and 7 ft, but every session is hammered by fresh to strong cross-shore winds. The wave quality is consistently poor, and the energy levels are moderate at best. There’s a weird little spike on Sunday afternoon the 9th with a 2 ft swell from the SSW, but it’s an 18-second period groundswell – long period, which could be tricky for a beach setup like this, and it’s still cross-shore. The energy is moderate (507).

The second week doesn’t get any better. Monday the 10th of August has a 3 ft SSW swell, 15-16 second period, but the wind is cross-onshore at 12-22 mph. The energy climbs to 755-814, but the wind ruins it. The rest of the week is a repeat: east-northeast swells, 3 ft to 6 ft, with fresh to strong east-northeast cross-shore winds. The energy stays moderate (200-800 range), but the conditions are always chopped out. Thursday the 13th and Friday the 14th of August see a south swell pop up again, but it’s the same windy story.

Honestly, nothing here is a goer. The wind never drops to offshore or even light, and the swell direction is always cross or cross-onshore. The combo is just wrong for clean surf. If you’re desperate, the morning of Tuesday the 4th of August is the only one that almost works, but even then, it’s marginal. The rest of the 16 days is a write-off.

Not much to work with, lads. A rare patch of poor options. Keep an eye on the charts, but don’t hold your breath.

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.
