The Lowdown

Oi, Rusty here again. Looking at the same 16-day window for ADs/Doubles, and I gotta say, it’s a tough watch. Mostly we’re sitting on our hands for a good chunk of it.

The run starts Sunday the 13th with tiny, weak surf. We’re talking 2-3ft NNE to NE swells with short periods, and the wind is a constant cross or cross-onshore breeze at 12-22 mph, chopping everything up. The water is a warm 81°F, normal for the season, but the energy is pitiful. It stays like that – small and ugly – until Wednesday the 16th.

Wednesday arvo, we get a bit of a pulse: a 3ft SSW groundswell with a long 18-second period. The energy reading jumps to 796, which is moderate, but that long period groundswell usually runs straight at beach breaks, and the wind is still cross, so it’s messy. No good.

From Thursday the 17th, the swell size comes up – 7ft from the ENE on Thursday, with energy over 1100. But the wind is a fresh 22-25 mph cross-shore, creating lumpy, messy waves. It’s getting a bit heavy for beginners, and the conditions are all chop. More for the kites than the paddles.

The back half of the outlook, from the 20th of September through to the 28th, brings consistent swell. Wave heights stay between 5ft and 8ft from the E to ENE, with huge energy numbers in the 900-1200 range. But here’s the whole story: the wind never lets up. It’s a constant cross to cross-onshore breeze from the ENE at 19-25 mph. The session on Wednesday the 23rd shows a marginal 8ft E swell with an 11-second period and 1266 energy, but it’s just too messy. There is no clean, offshore day anywhere in this window. No glassy dawny. No standouts.

If you’re keen on strong side wind and big chop, there’s plenty of that. But for a clean surf? It’s a big ol’ blank. The area can go through these runs; it just is what it is.

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.
