The Lowdown
Alright, Rusty here again. Let’s kick the same wisdom around in feet and miles for ADs/Doubles.
Right now, we’re looking at a grim stretch. Over the next week and more, the trade winds are blowing hard from the ENE, mostly cross or cross-on, just smashing the surface into lumpy cross-chop. Swell is from the same direction, so no good wrap. Water temp is around 81°, right about average for this time of year.
From Monday the 24th of August all the way to Saturday the 5th of September, it’s a string of poor surf. Swell heights bounce between 5ft and 8ft, but the period is short—mostly 7 or 8 seconds—so it’s just messy windswell. Combined wave energy sits in the moderate range, like 488 to 1111, but with the wind howling at 20 to 25 mph, the ocean is torn up. The bigger days, like 7ft+ on Tuesday the 1st of September, are only for experts. For anyone else, this looks better for kite surfing than paddle surfing.
There’s a faint hope on Thursday morning the 27th, with a long-period S swell at 17 seconds and about 4ft, and energy at 1037. But the wind is still cross at 20 mph, so it’s only marginal. That long period gives it power, but at a beach break like ADs/Doubles, it’ll likely break too straight and be a mess.
No real standouts here. This is one of those dead runs where you leave the board in the garage and wait for the wind to ease. Forecasts can flip, but right now, there’s nothing worth chasing for the full 16 days.
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.
