Alright, Rusty here, let’s break down what’s going on at ADs/Doubles.
For the first 11 days, from Monday July 13th through Friday July 24th, it’s a pretty flat and blown-out story. The wind is stuck in a fresh cross-shore or cross-onshore pattern, mostly from the ENE, just tearing the surface up. All the surf comments call it "poor" or "marginal." Not worth strapping in for any of that. The water feels about normal for this time of year.
The only real change comes late in the run. On Saturday July 26th, the combined energy jumps to 1067, that's strong. Monday July 27th shows a 1.1m swell from the east with a very long period of 14 seconds and energy at 1060. Then Tuesday July 28th has a 2.1m swell from the ENE with a 12-second period and energy hitting 1499 – that’s strong to very strong. So there's some oomph coming.
But the wind doesn’t let up. Still fresh cross-shore at 35 km/h from the NE and ENE. So you’ll have powerful, long-period groundswell, but it’ll be lumpy and chopped up. 2.1m is big – expert territory only. The long period will give good shape and energy, but the chop will make it rough. ADs/Doubles gets crowded *often*, so you might see a few people out, maybe fewer because of the messy wind.
Because of that persistent cross-wind, the whole first stretch looks more suited to kite surfing than paddling. Even that last surge of energy on the 26th through 28th is compromised by the wind. No clean standouts here – just a promise of power without the polish.
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.
