The Lowdown
G’day, Rusty here. I’ve had a proper look at what’s coming up for ADs/Doubles over this 16-day stretch, and I gotta be straight with you—it’s a tough run. There’s no standout, no real gem to get excited about. The whole period is riddled with strong cross-shore and cross-onshore winds from the ENE and NE, which just keep the surface messy. The swell sticks mainly from the ENE and E, but the short period (6–8 seconds) means it’s mostly windswell, lacking any punch or shape.
From Tuesday the 25th right through to at least the first week of September, it’s pretty much all "poor surf conditions." The wind is relentless—18 to 25 mph from the ENE—keeping the waves choppy and lumpy. Thursday the 27th morning saw a brief flicker of marginal surf with a long-period S swell at 4 ft (17 seconds) and combined energy hitting 1007 (moderate wave energy), but it’s still cross-shore and lumpy. That long period would make it better suited for a point or reef, but here at a beach setup, it’ll break too straight, and the fresh breeze kills any chance of clean waves.
A big lull follows: from Thursday afternoon on the 27th through to Monday the 31st, it’s all poor, with swell heights bouncing between 3 ft and 7 ft but always under that messy cross-wind. By Tuesday the 1st of September, the swell bumps up to 7 ft from the ENE, but the period only reaches 8 seconds, and the wind is still cross-shore at 22 mph—marginal at best, not worth paddling out for.
Later in the forecast, around Monday the 7th of September morning, the wind finally drops to a light breeze from the ESE at 6 mph, but the swell is 7 ft from the ENE with a 7-second period, and it’s cross-onshore. The wave energy is moderate (818), but the short period and onshore angle still spell choppy, messy conditions. Not a rescue.
Forget about beginners here when the swell’s over 5 ft—and it is for much of this run—and over 8 ft it’s expert-only, though we don’t hit that. Honestly, with these constant strong cross-winds and poor surf quality, this setup looks more interesting for kite surfing than paddle surfing.
It’s a long, blank stretch. ADs/Doubles isn’t a consistent spot normally, so a dry run like this is more typical. Keep an eye on the forecasts—things can shift.
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.
