The Lowdown

Alright folks, Rusty here. It’s been a quiet start and frankly, it’s going to stay that way for a while. We’re looking at a long, frustrating gap of flat, wind-affected days with nothing worth paddling out for until the calendar flips around. Hang in there.

We’ve got no solid options on the table for the first week and a half. From Monday the 14th all the way through to Thursday the 24th, the local scene is pretty much a write-off. Winds are hammering from the ENE and NE, mostly cross or cross-onshore at 15 to 25 mph, churning up a lumpy, messy cross-chop. Swell is small, short-period slop in the 3ft to 4ft range most days, with barely enough energy to push a ripple (combined energy values sitting mostly below 200, a few in the high 200s). There’s a bigger bump of 7ft to 8ft around the 17th and again on the 23rd, but with those strong onshore winds and short 7 to 10 second periods, it just looks like blown-out, bumpy junk. Honestly, for kite surfers it might be fun, but for a paddle surfer, it’s a hard pass.

The real bright spot—and I mean the *only* one—shows up late in the run. Around the 26th and 27th of September, things finally change. We’ve got a lovely SSW groundswell rolling in with a very long 14 to 16 second period, bringing moderate wave energy (combined energy around 393 to 558). The swell is small, only 3ft to 3ft, but it’s the conditions that make it a standout. Light NNE to N winds at 6 mph, cross-offshore, creating clean, glassy conditions. Water temp is sitting at a warm 81°, right on the money for the time of year, so the anomaly is practically nothing. ADs/Doubles is exposed to ESE, so this SSW swell should wrap in nicely. This is classic, small-wave fun for intermediates—clean, lined-up, and without the crowd if you pick your session right.

Then on Monday the 28th, it gets even better. A new pulse of SSW swell arrives with a very long 18 second period and a jump in energy (760). Another 3ft of clean, long-period groundswell under light offshore breezes. This is the pick of the entire forecast window. And to cap it off, Tuesday the 29th keeps that trend going with clean 4ft to 4ft ENE swell under light offshore airs.

So, the story is this: suffer through the junk for the first 11 days, then get ready for a sweet little clean window from the 26th through the 29th. The 28th is the absolute standout—set your alarm.

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.

ADs/Doubles is 14 km (9 miles) from the city of Kailua. If you plan a vacation in Oahu, look for hotels and other accommodation in Kailua. Kailua has rooms for a wide range of budgets as well as car hire and transport links.
