The Lowdown
Alright, let’s get real about the next couple of weeks, folks.
Honestly, it’s looking pretty bleak for a proper surf. We’ve got a long stretch of lumpy, cross-shore conditions and messy, weak waves on tap. The opening days are a write-off. The energy is there, but it’s coming from the wrong direction and the wind is tearing it to pieces.
We start with a bit of swell on Sunday the 6th, around 7ft, but it’s coming from the ENE with a stiff 30 km/h cross-breeze. It’s lumpy, it’s cross-chop, and the wind state is just poor. The guidance says it’s marginal at best, and I’m not seeing anything to get excited about. That’s a hard pass from me.
The whole first week is pretty much the same story. We’ve got some 5ft to 7ft swell, but the ENE wind stays on it, chopping everything up. The period is around 11-12 seconds, which is okay, but it doesn’t matter when the surface is a mess. You’d be fighting the elements more than riding waves.
The energy readings do drop off mid-week, down to around 690 on Wednesday the 9th, but there's still no quality. We see a couple of days where the swell dips to under 3ft, and the period drops to 7 or 8 seconds. That’s just short-period wind slop. Not worth your time.
You want to know about the standout? The one tiny glimmer in all this is Monday the 21st. The wind finally swings around to the east-southeast and drops right off to just 5 km/h in the afternoon. That’s as close to glassy as we’re going to get. The swell is a modest 5ft from the ENE with an 8-second period, so it’s not going to be epic, but it’ll be *clean*. The energy is still only moderate (431 mm), but you might actually catch a few fun, crumbly ones at ADs/Doubles. That’s your best bet in the whole window, and it's a pretty low bar.
Before that, there’s nothing that gets the heart racing. A long stretch of nothing, really. A week of poor conditions, then another few days of small, cross-shore junk. It’s the kind of run where you’d be better off checking the forecast again in a few days.
There will be a lot of flat, bumpy days between now and then. I'm not going to sugarcoat it. The water temp is 81°, which is pretty much normal for this time of year, a touch warm, nothing crazy.
So, mark your calendar for the 21st. It might be the only day the ocean gives you anything back.

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.
