The Lowdown
Alright, Rusty here. Let’s have a good look at what’s coming our way for A-Ds-Doubles. I’ll be honest with you right off the bat: we’ve got a long, frustrating stretch ahead before we see anything worth paddling out for. This isn’t one of those quick turnarounds.
The water temp is sitting at 80.4°F, which is pretty much dead average for this time of year, so no surprises there.
Right now, and for the next week and a half, it’s pretty much a write-off. We kick off Monday the 31st of August with a 6.9ft swell from the ENE, but that’s getting hammered by a fresh 22 mph cross-wind. The water’s a lumpy, choppy mess. The wave energy is moderate at best (767), but with that wind, it’s just not surfable. This pattern locks in day after day. Tuesday the 1st, Wednesday the 2nd… same story. The swell drops a bit, the wind doesn’t let up. We get a brief pulse of long-period groundswell from the south on Wednesday afternoon – a 3.0ft swell with a 16-second period – but it’s still blowing a cross-shore gale. That’s a wasted opportunity.
Then things get ugly. Thursday the 3rd and Friday the 4th see the swell jump to 9.8ft and then 11.5ft, but the wind cranks up to a strong 28 mph cross-shore. The energy spikes to 1805, but it’s just a wall of whitewater and cross-chop. This is kite-surfing territory, not paddle surfing. It’s too big and messy for anyone but the most hardcore, and even then, the quality is zero.
Saturday the 5th and Sunday the 6th are a bit of a tease. The swell drops to 8.2ft, but it’s a long-period 13-second groundswell from the ENE, swinging east. The energy is huge, reaching 3506 on Sunday morning. But the wind is still a fresh cross-shore, and the surf is just lumpy and inconsistent. It’s a marginal call at best. Too much energy for the conditions.
Monday the 7th of September is the first time things get interesting, but only for experts. We’ve got a 9.8ft to 13.1ft swell from the ENE with a 12 to 13-second period. The wind swings offshore from the NNE on Monday afternoon, and the conditions go clean. The energy is massive, hitting 5143. The problem is, it’s just too big. The forecast says it’s too big for this break. This is a big-wave day for the crew with big balls and big boards. For everyone else, stay on the beach.
After that, it slowly winds down, but the wind stays onshore or cross-shore all the way through to the 15th of September. The swell drops below 6.6ft, the energy fades into the hundreds, and the wind, while lighter, is still ruining any chance of clean waves.
The one true standout, and it’s a long way off, is Monday the 14th of September. The swell is a modest 5.9ft from the ENE with an 8-second period, but look at the wind: near calm, a slight air from the NE, and it’s a cross-offshore breeze. The water goes clean. The energy is low (457), so it won’t be big, but for the first time in two weeks, you might get some clean, rideable lines at A-Ds-Doubles. It’s a long-range call, so don’t book the week off yet, but keep an eye on it. It’s the only window in this whole 16-day outlook where the conditions actually line up.
So, the bottom line: a lot of waiting, a lot of wind, and one potential gem way out on the 14th. It’s a tough run.

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.
