The Lowdown

Oi, Rusty here. Let’s be straight with you – the outlook for ADs/Doubles over the next 16 days is a tough one. I’ve looked at the whole run, and truth be told, there’s no period where the conditions really come together for a proper paddle session. The wind is a persistent problem, and the surf quality just never gets there.

We kick off on Monday, July 20th, with a long-period groundswell from the south, about 3 ft, with a period of 16 seconds. That’s got some serious energy behind it (569), but the wind is a cross-shore from the ENE at 16 mph, already putting a chop on it. Conditions are marginal. By the afternoon, the wind picks up to 19 mph, and it’s a total write-off.

Tuesday July 21st and Wednesday July 22nd follow the same pattern – we see a bit more size, with the swell building to 5 ft from the ENE on Wednesday afternoon, but the wind is a fresh cross-shore at 22 mph, creating a lumpy mess. The combined energy jumps way up to 1191, but it’s all for nothing with that wind.

Thursday July 23rd through Saturday July 26th, the swell gets bigger, hitting 8 ft from the ENE on Friday July 24th with a short period of 7-8 seconds. That’s expert-only territory just on size, but the wind is howling from the ENE at 22-25 mph, making it a full-on, messy, cross-shore nightmare. The energy is through the roof (1423 on Friday afternoon), but it’s unsurfable. Honestly, with that much wind and messy sea, it looks more like a kite-surfing setup than a paddle session.

We get a slight break in the wind on Tuesday July 28th, with a moderate breeze at 12 mph, and the swell is a cleaner 6 ft from the east with a 12-second period. The energy is still solid (1142), and it’s the best we’ll see, but it’s still a cross-shore wind. The forecast scores it as marginal, and I’d agree – it’s a maybe, not a goer.

After that, from Wednesday July 29th right through to Monday August 3rd, the pattern repeats: manageable swell sizes, but always hampered by a cross or cross-onshore wind. The energy drops off significantly, and the forecast is consistently poor. There’s a gap of several days with no real recommendation.

The bottom line: there are no standout days. The persistent ENE wind just kills the quality at this exposed break, which needs offshore from the NW for clean conditions. The water temp is about average for the time of year, nothing unusual there. It’s a disappointing run, but forecasts can change. For now, I’d keep the board in the bag.

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.
