The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' over the next couple of weeks.
Right off the bat, I gotta be straight with you – it's a pretty grim stretch for ADs/Doubles. The whole 16-day run is a total write-off for decent surf. We're looking at a solid two weeks-plus of nothing but poor surf conditions, day after day. The wind is the main villain here, howling out of the ENE almost constantly, gusting 18 to 31 mph, which is just tearing the surface to shreds. It's a bummer, but sometimes the ocean just closes the door for a while.
Starting from Wednesday, August 12th, through the whole week, we've got a long-period groundswell from the south, with 3 ft to 4 ft of swell, but that 18-22 mph cross-shore wind is killing it stone dead – lumpy cross-chop and no quality. You'd be wasting your time.
The weekend of August 15th and 16th gets a bit more interesting for the wrong reasons. Saturday the 15th sees a big jump in wave height, with 12 ft of windswell from the ENE, but the wind is screaming 28-31 mph. That's not surf, that's a washing machine. For the experts only, if they're even crazy enough. Sunday the 16th brings 13 ft swell with a risk of thunderstorms and a near-gale onshore wind. The setup looks more interesting for kite surfing than paddle surfing.
The following week, from August 17th to about the 23rd, the swell drops back down, but the wind stays stubborn. We see 5 ft to 7 ft of messy, short-period windswell (7-8 seconds), but it's still cross-on or cross-shore with that ENE breeze at 16-22 mph. Just lumpy, choppy, and blown out. The water temp is about 81°, which is normal for the time of year, but you won't be feeling it.
Then from the 20th through to the 27th, it's a mix of small SSW groundswells (2 ft to 4 ft, with periods of 13-18 seconds) and tiny ENE windswell. Again, the wind is always cross or cross-on. It's a long, dull stretch with zero recommendations. A blank run like this is more normal for the area when the trades set in, so don't get too down. It tends not to stay this poor forever, and forecasts can change.
For now, just put the board away, grab a cold one, and wait for a turn in the weather.
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.
