The Lowdown

Alright folks, Rusty here, lookin' at the charts for the next couple of weeks. It's a bit of a mixed bag, so let's get into it.

Right off the bat, we're looking at a pretty rough start. The first few days are a write-off with strong onshore winds and messy, lumpy conditions. You're not gonna want to paddle out Thursday the 3rd through Saturday the 5th. The cross-shore wind is howling at 25 mph, and the combined wave energy is already pumping hard, but it's all just a washing machine. This isn't a surf forecast, it's a warning.

We finally get a small window of interest on Sunday the 6th, but it's still pretty rough with a risk of thunderstorms and a cross-onshore breeze. The energy is getting up there, but the wind is just ruining it. Definitely not the best on offer.

The real standout, and I mean the absolute standout, is Monday the 7th. Now, I gotta be straight with you, this is a weird one. The morning is a total mess – big, fat, ugly wind. But look at the afternoon. The wind is whipping out of the southeast at 25 mph, but it's swingin' *on* to the shore. The swell is a monster, a solid 18 ft from the SSW with a long 15-second period, and the energy is just insane. This is a beast. The problem is, the file says it's too big for this break. ADs/Doubles is just gonna be a freight train closeout. If you're an absolute expert, maybe you find a corner, but for everyone else, that's a hard pass. Take a look from the cliff, but leave the board in the car.

After that, we get a bit of a lull. Tuesday the 8th has some clean-ish afternoon energy, but it's small and cross-on. The rest of that week and into the next is just a whole lot of nothing. The wind stays on it, and the swell drops off. There's a solid 10-day gap where the surf is just marginal or poor.

Then, we get a little glimmer. ADs/Doubles on Monday the 14th of September. The swell is a clean 8 ft from the ENE, and the wind is a light breeze, almost glassy. The period is short, only 8 seconds, so it's gonna be a bit bumpy and fat, but it's the best we've seen in a while. The energy is solid, so there's some push. The crowds will be a factor here, as it gets busy, so get in early. The water temp is a tropical 81°, right on the money for this time of year.

So, to sum it up: the next week is a write-off for the most part. The only real day to keep an eye on is Monday the 14th. It's not perfect, but it's the only game in town. Keep your fingers crossed for a change in the long-range.

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.
