The Lowdown
Alright, Rusty here. Let’s see what we’ve got for the next couple of weeks.
Honestly, it’s a tough outlook for ADs/Doubles. The whole 16-day window is a long, frustrating grind with nothing we’d call a proper surf session. The pattern is locked in with a strong, persistent wind from the east-northeast that just won’t let up, keeping the ocean messy and choppy.
Starting off now, through the end of July and into the first few days of August, we’ve got some serious size—10 ft on Saturday the 1st of August and 8 ft on the 2nd—but it’s all wind-affected. The swell is coming from the east-northeast with a short, weak 8-second period, and the wind is blowing hard at 25 to 28 mph. That’s creating heavy cross-shore chop and messy conditions. The wave energy is strong to very strong, hitting 1455 and 1494 (combined energy), but with that wind, it's a washing machine. For beginners, anything over 5 ft is a handful, and this is well over that; the 10 ft days are strictly for experienced crew, and even then, the quality is poor. This setup actually looks more interesting for kite surfing than paddle surfing.
We do get a small shift around Tuesday the 4th of August. The swell period jumps to 11 seconds, bringing a bit more push and shape (combined energy 780), but the wind is still a cross-shore breeze from the northeast at 12 mph, which keeps the surface bumpy. It’s only a 6 ft wave from the east-northeast, and the forecast calls it marginal. Not exactly something to get excited about.
After that, things drop off hard. From the 5th of August onward, the swell gets smaller and confused. We see some longer period energy—14 to 18 seconds—from the south-southwest, which is not the optimum direction for this break. The wave heights drop to under 3 ft, and the combined energy falls below 600. That long-period groundswell (over 15 seconds) can make waves break too straight on a beach break, so it’s not doing us any favors here. The wind stays steady from the east or northeast, mostly in the 12 to 19 mph range, so the ocean stays lumpy and choppy.
There is a brief moment on Tuesday the 11th of August where the wind eases to just 6 mph from the east-southeast, and the swell is a waist-high 3 ft from the south-southwest with a 15-second period. Combined energy is 594. It’s still cross-onshore but light, so you might find a cleaner wave if you’re desperate. The forecast gives it a 2 out of 10, which is about the best we see.
So, a long, frustrating stretch with no real standout. The break is fairly consistent in the sense that it gets swell, but the wind is the villain here, ruining any chance of quality. The water temp is 80°F with a normal anomaly of +0.5°, so it’s about average for the time of year. For the crowd situation, it’s often busy here, but with conditions this poor, I wouldn’t worry about company.
Stay patient. The forecasts can change, but for now, leave the boards in the car.

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.
