The Lowdown
Right, let’s have a look at what’s on the table for ADs/Doubles over the next couple of weeks. To be honest, it’s a pretty rough start. The first week and a half is mostly a write-off. The wind is relentless out of the east-northeast, pumping at 19 to 25 mph for the first several days, whipping up a lumpy, messy cross-chop that’ll have you fighting the conditions more than riding the wave. The swell is there, but it’s junk – short-period, wind-affected slop between 5ft and 10ft, with moderate to strong combined wave energy (866 to 1762). Don't bother paddling out from Tuesday the 1st right through to Friday the 4th; it’s all poor surf. Saturday the 5th and Sunday the 6th see a slight improvement in the swell period, stretching to 12 to 13 seconds, which adds a bit of grunt (energy climbing to over 2300), but that cross-wind is still there, messing up the surface. It only gets a “marginal” tick. Same story from Monday the 7th through Tuesday the 8th – lighter winds, but they’re cross-onshore, and the swell drops a touch.
Wednesday the 9th and Thursday the 10th it’s back to fresh cross-breeze and poor conditions. The real kicker comes on Sunday the 13th and Monday the 14th. A big, powerful SSW swell rolls in on Sunday – 10ft at 12 seconds, with very strong wave energy (2569 to 3119). That’s a heavy groundswell. But here’s the thing – ADs/Doubles is an exposed spot and this swell is too big for the break, even with favourable wind (gentle to moderate cross-shore). This is expert-only territory, and honestly, at that size here, it might even be more interesting for kite surfing than paddle surfing. Monday the 14th keeps the size up with a 12ft S swell, but that period drops to 8 seconds, and the wind stays cross – again, too big and messy for a proper paddle session. After that, the drop-off is quick. From Tuesday the 15th onwards, we’re back to small, weak, and mostly poor surf through to Wednesday the 16th.
So, if you have to pick a session, Saturday the 5th or Sunday the 6th are your best bet for something rideable, with that longer-period swell offering better shaped waves (around 8ft to 8ft from the ENE), but don’t expect perfection with that cross-wind. The real standout is the Sunday the 13th window for experts only, with a serious SSW groundswell, but you’d need to know the break well and be ready for a beating.
Water temp is sitting at 81°F, which is pretty normal for this time of year – no surprises there.

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.
