The Lowdown
Alright folks, Rusty here. Let me take you through what we've got cookin' for the next couple of weeks.
Alright, let's be straight with you. The 16-day window kicks off with a bit of a tease on Tuesday afternoon, July 28th, but it ain't gonna be pretty. The water is a warm 80°, which is bang on average for this time of year, so no drama there. The real issue is the wind and the quality of the swell.
We're looking at ADs/Doubles as our only real option on the menu. The first real chance to get wet comes on Wednesday, July 29th. The morning session is a bit iffy, with a 7ft swell from the ENE and a 10-second period, but the wind is a cross-off at 12 mph, which will keep things reasonably clean. The combined energy is moderate (939). The afternoon is where it gets interesting. The swell drops a touch to 6ft from the NE, and the period drops to 9 seconds, but the wind backs off to a gentle 9 mph cross-off. The energy is still moderate (779), and the forecast says "very good surf conditions." This is the best we're going to see, folks. The swell direction is nearly perfect for this spot, and the light cross-off wind will make for some clean, fun walls. It's a fairly consistent break, so you'll get waves, but just know that crowds are often a thing here.
Now, Thursday the 30th through the rest of the first week and into the second... it's a write-off. The wind shifts onshore from the ENE, picking up to 19-28 mph, and the quality just tanks. The swell hangs around 5ft to 10ft, but it's all short-period, choppy junk. The combined energy gets strong (up to 1591), but it's all wind-blown mess. These are "poor surf conditions" days, one after the other. The water does cool down a bit, but the wind just ruins everything.
We get a long, boring stretch of nothing worthwhile from Thursday, July 30th, all the way through to the end of the forecast. There's a tiny flicker of longer-period swell (11 seconds) on Tuesday, August 4th, but the wind is still cross, and the heights are just 5ft to 6ft. It's still a "marginal" call.
Then, from August 5th onward, the swell drops right off, and the wind stays stubbornly cross or cross-on from the east. The second week is a total washout. The energy drops to weak levels (under 500), and the periods are short and messy. Even a late appearance of a long-period SSW groundswell (18 seconds on August 9th) doesn't help because the wind is still howling at 22 mph, making it a lumpy, cross-shore disaster.
The bottom line: If you're going to paddle out, your only real window is Wednesday afternoon, July 29th, at ADs/Doubles. The 6ft NE swell with those light offshore breezes will be the cleanest we see. Everything else is a battle with the wind and chop. For the rest of the time, with that strong onshore flow and big, messy waves, this setup looks more interesting for kite surfing than paddle surfing.
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.
