The Lowdown

Alright, it’s gonna be a tough watch for the next couple of weeks here at ADs/Doubles. The long-range picture is trying to fire up, but we’ve got a serious dry spell at the start that feels like it’s never gonna end.

From Tuesday the 15th through to around Thursday the 24th, we’re stuck in a brutal pattern. The wind is blowing hard out of the ENE and NE, side-shore or side-on-shore, and it’s got a nasty lumpy chop on it most days. The swell direction is bouncing all over the place – NE, E, even some SSW pulses – but the wind just wrecks any chance of a clean wave. Swell heights are puny at first, around 3 ft, with a weak combined energy reading (150) and a short, gutless period of 8 seconds. It’s just not happening. We do see a spike in energy on the 16th afternoon with a long-period SSW groundswell hitting 3 ft but 18 seconds and a massive energy jump to 737, but that cross-shore wind makes it a mess. That’s a tease, not a treat.

We get a big build of swell towards the end of the week starting the 17th, with heights climbing over 7 ft and combined energy readings hitting three and even four digits – 982, 1232, 1103 – but the quality is still poor. The wind is relentless. By Sunday the 20th we’re looking at 8 ft of choppy, lumpy cross-on-shore slop. This setup at a beach/reef break like ADs/Doubles is honestly looking more interesting for a kite surfer than a paddle surfer. The water temp is sitting at about 81°, which is pretty average for this time of year.

There’s a brief glimmer on Thursday the 24th. The wind finally swings around to the SSE and drops to just 6 mph with an onshore direction for the afternoon. Swell is still a solid 8 ft from the ENE with a period of 8 seconds and combined energy of 940. The forecast notes suggest the tide and wind are favorable, but that it might be too big for the break. At over 8 ft, this is really only for experts. If you’re a solid, experienced surfer and can handle a big, lumpy beach break, that afternoon might be your only shot. The risk of thunderstorms is there too.

After that, it’s a quick return to the same old story for the rest of the month: strong ENE winds, lumpy cross-shore conditions, and poor surf right through to the end of the 16-day window on September 30th. Swell stays up around 3 ft to 8 ft but it’s all blown out.

Honestly, the best on offer across this entire forecast is that Thursday afternoon the 24th. It’s not pretty, and it’s not for the faint-hearted, but it’s the closest we get to a clean wave. If the wind holds and you’re an expert, you might snag a few.

Stay patient.

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.
