The Lowdown
G’day, I’m Rusty. Let’s talk about what’s coming at ADs/Doubles. I’ll be honest – it’s a rough stretch for the next couple of weeks. There’s nothing that’s gonna get you excited, and most days you’ll be dealing with cross-shore winds and lumpy, messy conditions. The water temp is sitting at 81°, which is about average for this time of year, so no surprises there.
We start Friday the 11th of September with poor surf. There’s a bit of swell at 5ft from the ENE, period at 11 seconds, and combined energy at 481 (moderate), but that ENE breeze at 15 mph is cross-on, making it choppy and ugly. Not worth paddling out. That trend sticks through the weekend and into the next week – Saturday the 12th has 3ft from the ENE, period 10 seconds, energy at 252 (moderate), but cross winds and a cross-chop spoil it. Sunday the 13th is similar with 3ft from the NNE, period 9 seconds, energy at 182 (weak), and still messy.
From Monday the 14th to Thursday the 17th, the wind gets stronger – hitting 25 mph on Wednesday and Thursday. The swell picks up to 5ft on Wednesday morning from the ENE with a short period of 6 seconds, energy at 286 (moderate), but it’s cross-shore and lumpy. Thursday the 17th sees a jump to 8ft from the ENE, period 8 seconds, energy at 865 (strong), but the wind stays at 25 mph cross-shore, so it’s messy and only for the hardcore. Friday the 18th has a brief change with a 3ft swell from the SSW, period 17 seconds – that’s a long-period groundswell – energy at 1069 (strong), but the wind is cross-on at 22 mph, so it’s lumpy.
The second week is more of the same. Saturday the 19th through to Tuesday the 22nd, we’ve got swell from the SSW and ENE, sizes around 3ft to 6ft, periods between 7 and 16 seconds, and energy bouncing between 479 (moderate) and 762 (moderate). The wind stays cross or cross-on, 15 to 25 mph, so it’s always lumpy or choppy. Not a single standout.
Now, on Wednesday the 23rd and Thursday the 24th, things get a bit interesting – the swell hits 8ft from the ENE on Wednesday morning, period 8 seconds, energy at 1099 (strong). That’s big, but with a short period and cross-shore winds at 15 mph, it’s marginal at best – definitely expert-only if you’re game. Thursday the 24th has 7ft from the ENE, period 9 seconds, energy at 966 (strong), and the wind swings lighter from the S and SSE at 9 mph, making it cross-on but gentler. Still, it’s not clean enough to call a winner.
After that, Friday the 25th and Saturday the 26th fade back to poor surf with 5ft to 7ft from the ENE, cross-shore winds, and messy conditions. Bottom line: there’s no good surf on offer in this 16-day window. The consistent cross-shore winds and lack of a clean swell window mean you’re better off finding something else to do. Forecasts can change, but right now, it’s a blank run. Stay tuned, though – it never stays poor forever.

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.
