The Lowdown
G’day, I’m Rusty. Let’s look at what ADs/Doubles has cooking over the next couple of weeks. Honestly, the outlook is pretty grim. The whole pattern is dominated by messy winds and lumpy, choppy conditions. The water temp is sitting at a normal 81°F, about average for this time of year, so you won’t need a thick wetsuit.
Starting Saturday the 5th of September, we’ve got a solid 7ft ENE swell with a 13-second period, packing a punch – combined energy is 2423 (strong). But the wind is cross-shore at 22–23 mph, and it’s all lumpy cross-chop. The sky is clear, but the quality is trashed. Sunday the 6th into Monday the 7th, the swell holds around 7ft to 8ft, but the wind goes cross-onshore and there’s a risk of thunderstorms. Scores drop to zero – it’s poor surf. By Tuesday the 8th, the wind shifts south but stays cross-onshore and fresh, and the swell starts fading.
There’s a tiny window on Wednesday the 9th: the swell drops to 3ft from the SSW with a 14-second period, combined energy 566 (moderate). Wind is light onshore at 9 mph, but with rain showers later, it’s marginal at best. After that, from Thursday the 10th right through to Monday the 15th, we’re stuck with ENE wind swell, mostly 5ft to 6ft, short periods of 7–8 seconds, and fresh cross-shore winds. The energy numbers fall to the 200–400 range (weak), and it’s all lumpy and choppy – a full week of nothing.
Into the second week, Wednesday the 16th of September brings a long-period SSW groundswell – 3ft at 18 seconds, combined energy 951 (moderate) – but the wind is a fresh cross-shore at 19 mph, so still messy. Thursday the 17th is similar but smaller at 3ft. The best shot is probably Friday the 18th of September: 4ft from the SSW with an 18-second period, combined energy 1183 (strong). But the wind is cross-shore at 19 mph in the morning (fresh breeze), and the notes say “marginal.” It’s a long way out and not clean. Crowds at ADs/Doubles can often be heavy, so don’t expect solitude. Saturday the 19th and Sunday the 20th fade out on the same swell, dropping to 3ft.
There’s no standout session here. The best on offer is that Friday the 18th morning, but it’s uncertain and the wind is against it. For three weeks out of the sixteen days, there are day after day with no recommendations. If you’re keen, maybe sneak a look at that Wednesday the 9th or Friday the 18th, but keep your hopes low. Honestly, this stretch looks more interesting for kite surfing than paddle surfing, with those steady side-shore winds and lumpy conditions.
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.
