The Lowdown

Alright, Rusty here. Let’s break down what’s happenin’ at ADs/Doubles for the next couple of weeks. I’m not gonna sugarcoat it – it’s a long, dry spell before we get anything worth paddlin’ for.

Water temp is 81°, right where it should be for this time of year. Nothin’ unusual. But the surf? Man, it’s a tough run. From the 7th all the way through the 21st of September, it’s poor to marginal. There’s some energy in the water, like a 6ft east swell with a 12-second period on the 7th (combined energy of 1435), but that ESE wind blowin’ at 22 mph is gonna tear it up. The 8th has a bit more size at 7ft from the ENE, but it’s lumpy and cross-onshore – not worth the hassle.

The swell drops off hard after that, with heights under 3ft and period all over the place. The 16th of September has a 3ft SSW groundswell with a very long 18-second period and a moderate energy of 662, but the wind is cross or cross-on again. That kind of long-period swell just closes out on an exposed beach break like this.

The one bright spot? Tuesday the 22nd of September. That morning is glassy – dead calm wind. The swell is tiny, just 2ft from the SSW with a 14-second period, and the combined energy is a modest 271. It’s not gonna be big, but it’ll be clean. If you want a quiet, small-wave session with perfect conditions, that’s your only real shot.

Crowds can be an issue here when it’s on, but with this much inconsistency, you’ll likely have the place to yourself most days. Just don’t expect much.

Circle the 22nd of September. Everything before that is a wash.

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.
