The Lowdown
Alright, Rusty here again, giving you the skinny on ADs/Doubles in imperial.
For the next week or so, it’s a tough stretch. The wind is stuck out of the east-northeast, blowing cross or cross-onshore most days, and it’s keeping everything lumpy and ragged. The water temp is about 80°, pretty normal for this time of year, so no worries there. The first few days have tiny swell and bad wind, so don’t bother paddling out unless you like a beating.
Things start to look slightly better around Sunday the 26th. The swell picks up with some longer period energy, but that cross-wind is still making it a bumpy session. The wave energy is moderate, hitting the 1300s (combined energy), but it's still just "marginal". The real window opens up on Wednesday the 29th of July. That morning the wind turns cross-offshore from the north-northeast at 15 mph, cleaning the surface right up. You’ve got 7ft of E swell at 12 seconds, with moderate energy (1604). The afternoon is even cleaner, with 7ft from the ENE at 11 seconds and solid moderate energy (1431). That Wednesday afternoon is your standout. The wind is light and clean, and the swell has some real push. It won’t be huge, but it’ll be the best shape you get all week. Don’t be surprised if there’s a few other heads out—crowds are often there for a reason.
After that, it fades again. The swell hangs around but we lose that good wind, and by early August it’s back to cross-onshore junk at 15-22 mph. There’s a size spike on Wednesday the 5th of August with 8ft from the ENE at 13 seconds and strong energy (2517), but the wind is still cross and messy. That’s for experts only, and honestly, with that wind it’s looking more like a kite session than a clean surf.
So to sum it up: your best bet is the 29th of July. Everything else is a bit of a waiting game with a lot of chop mixed in.
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.
