The Lowdown
Alright, Rusty here again. Let’s look at the same picture, but in feet and miles per hour.
It’s looking lean for ADs/Doubles over the next 16 days. The wind is the main villain here.
Starting Friday, August 7th, we’ve got a 3ft wave from the ENE, but a stiff 16 mph cross-shore from the NE is just ruining it. The water is about 80°, which is what you’d expect.
The first week, through August 14th, is a total loss. The wind is hammering from the ENE or NE at 19 to 25 mph, all cross-shore or cross-onshore. The swell is there, mostly 5ft to 7ft from the ENE, but the energy is moderate and the period is short – 6 to 8 seconds – so it’s just a lumpy, choppy mess.
The second week, from August 15th, the swell gets bigger. By the 17th, we’re looking at 8ft waves from the ENE, with strong energy. But the wind cranks up to a strong 25 to 28 mph, all cross-shore. The period is still short, under 10 seconds, so it’s a big, blown-out wall. That’s expert-only size, and with that wind, it’s a slog.
The only real chance comes at the end. On the morning of Wednesday, August 19th, the wind drops to a gentle 9 mph from the ENE. The swell is 6ft from the ENE, with moderate energy. The wind is still cross-shore, but it’s lighter, so the surface might be a bit cleaner. Friday, August 21st, also has a morning window with 6ft ENE swell and a 16 mph breeze, and the model is calling it marginal. It’s the best we’ve got.
The pick of the litter? The mornings of the 19th and 21st of August. The swell is sizeable, the wind is lighter, and you might snag a few clean ones. But with that persistent cross-shore wind and short-period swell, this spot is looking more like a kiteboarding zone than a surf spot for most of the run. Don’t hang up your wetsuit, though – it never stays this bad 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.
