The Lowdown
G’day, this is Rusty.
Looking at A-Ds-Doubles over the next 16 days, it’s a slow start and mostly a bust, with one solid window for the experienced crew. Water temp is 80°F, right where it should be for this time of year, no real anomaly to mention.
Sunday the 26th has clear skies but that 22 mph cross-wind from the ENE shredding up a 3 ft swell with a 16-second period. The energy is high (1342), but the sea is lumpy, so it’s a write-off. Monday the 27th shows a jump to 5–5 ft east swell, 14-second period, still cross-winds at 19 mph. The call is marginal, those sets might be spaced out, but the surface is ugly.
Tuesday the 28th afternoon is where we get serious. The swell hits 10 ft from the east, wind goes NNE at 19 mph going cross-off, and energy jumps to 2998. Clean conditions are predicted, but at this size, it’s expert-only. Wednesday July 29th morning is your absolute standout: 10 ft ENE swell, light offshore from the NNW at 6 mph, period 10 seconds. The energy (1827) is paired with glassy, clean faces. That offshore breeze will groom the waves, but again, this size means only the experienced should be out. Crowds are likely.
Wednesday arvo the wind swings cross-on light, dropping the swell to 7 ft, period 9 seconds, energy down to 1000—marginal. Then from Thursday July 30th through August 4th, it’s relentless ENE cross-winds, 16 to 28 mph, with swell between 6 ft and 10 ft, periods down to 8 seconds. This is all messy cross-chop and onshore slop, not worth the paddle.
Early August 5th onward, the swell fades to 3 ft with longer periods (10–14 seconds), but the wind stays cross and lumpy. Energy drops into the low hundreds, weak. August 9th and 10th you see a tiny 2 ft groundswell from the SSW with 14 seconds, still cross-winds at 19–22 mph. The energy is feeble (under 450), and here it’ll just close out.
So the only real session is Tuesday afternoon through Wednesday morning of July 28–29. I’d peg Wednesday morning as your best bet—clean, heavy, and a proper challenge. Everything else is a long gap of poor conditions.
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.
