The Lowdown

Alright folks, Rusty here. Let’s break down what’s coming for ADs/Doubles. This spot is wide open to an east-southeast swell direction, and we’ve got a full 16-day window to look at.

Here’s the honest truth: from Saturday, August 8th, right through the first week, we’re looking at a total blank run. The wind is hammering from the east-northeast at 19 to 22 mph, cross-shore, and it’s turning the ocean into a lumpy, choppy mess. The swell is coming from the east-northeast but with short periods of 6 to 8 seconds, so it’s weak and jumbled. The wave energy goes from moderate (264) to strong (621), but with this wind, it’s all junk. Every session is marked as “poor surf conditions” with a score of zero. Don’t bother paddling out.

You’ll have to sit through more than a week of this. The wind stays fresh and cross-shore, and the swell just keeps building. By Friday, August 14th, the swell hits 2.5m (8ft) from the east-northeast, and by Saturday afternoon, August 15th, it’s a messy 4.0m (13ft) with the wind up to 28 mph. That’s raw power (energy over 2900), but with this onshore wind and a beach setup, it’s a kitesurfer’s playground, not a paddle surfer’s dream.

Then comes Sunday morning, August 16th. This is the one real standout. The wind turns cross-offshore from the north at 25 mph, and the report says wind and tide are favorable. The swell is a solid 3.5m (12ft) from the east with a 9-second period, and the energy is very strong (3196). But the catch is clear: the swell is predicted to be too big for this break. This is expert-only territory, and even then, it’s going to be heavy and pushing hard. It scores an 11 out of all these zeroes, so it’s the best on offer if you’re brave enough. The water temperature sits at 80°F, about average for this time of year.

After that, Monday, August 17th, gives you a marginal 2.2m (7ft) east-northeast swell, but the wind goes onshore from the southeast, so it’s messy again. The rest of that week and into the next weekend (through August 23rd) is just the same story: cross-shore winds, lumpy conditions, and poor surf. Nothing else to get excited about.

Bottom line: if you’re an expert and can handle a big, heavy 12ft wave with a cross-offshore wind, Sunday the 16th is your only window. Everyone else should plan on skipping this run. The setup here looks more interesting for kite surfing than paddle surfing for most of the forecast. Things can change, but right now, it’s a long, quiet stretch.

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.

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.
