The Lowdown
Alright, listen up. Rusty here.
Straight off the bat, this 16-day window is a write-off for any decent surf. I’ve looked at the whole picture, and it’s a bust. For the entire sixteen-day run from now through the end of the month, there’s not a single session I’d call good. It’s a long, flat spell with no real standouts.
The only spot on the cards is ADs/Doubles, but it’s not worth paddling out for. The water temp is sitting at 80°F, which is bang on average for this time of year, but that’s the only thing that’s normal. The swell is coming in from the ENE, but the winds are a mess – cross-shore or cross-onshore from the ENE and NE at 12 to 25 mph. This means it’s choppy, lumpy, and crossed-up every single time. Not clean, not fun.
There’s a tiny window on the afternoon of September 22nd and the morning of the 23rd where it’s labelled as marginal, with a bit of E swell around 6 ft to 6 ft (moderate wave energy around 585 to 765). Even then, the wind is still cross-shore. It’s just not good enough to call "surfable" in my book. For the rest of the run, the forecast is "poor surf conditions" with zero scores, so don't even bother checking the cams. It’s a blank run, plain and simple.
In an area where consistent waves are the norm, a stretch like this is a bummer. But the forecasts can always flip. Keep your eye on it.
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.
