The Lowdown

Alright folks, Rusty here. Let’s see what this 16-day stretch has in store for us at ADs/Doubles. Honestly, it’s a tough run. The forecast is littered with poor surf conditions, and the wind is almost always a problem.

We kick off the first week with a lot of energy in the water, but it’s a mess. Monday the 7th has a solid 8 ft of swell out of the ENE, packing a ton of power (energy of 2533), but with a 16 mph cross-onshore wind, it’s choppy and poor. That continues through Tuesday with even stronger wind. The swell drops a bit Wednesday the 9th, but we finally see a change. The wind eases to a light breeze, and while the swell is only 3 ft from the SSW, the period stretches out to 14 seconds. That’s a proper groundswell, and the energy is moderate (726). The wind is light cross-onshore, so it’s not glassy, but it’s the cleanest we’ve seen. This is our best bet in the first week, but it’s still marginal. It’s a small, long-period swell, so it’ll be better shaped and less lumpy, but don’t expect much size.

The rest of the first week and into the second is a write-off. From Thursday the 10th through to the 15th, we’ve got a solid run of cross-shore and cross-onshore winds, mostly from the ENE and NE, with speeds between 9 and 19 mph. The swell is small, often under 3 ft, and the energy is weak. It’s just messy, lumpy, and not worth paddling out for.

Now, there’s a glimmer of hope way out in the second week. On Wednesday the 16th afternoon, a very long-period SSW groundswell appears, with a period of 18 seconds and moderate energy (878). The problem is that the wind is still a moderate cross-shore from the NE, so it’s going to be chopped up. The same holds for Thursday the 17th and Friday the 18th – the swell direction is SSW, periods are 16-17 seconds, but the wind is always cross-shore or cross-onshore, keeping things messy. The best chance seems to be Saturday the 19th afternoon. The wind drops to a light breeze, and we’ve got a 3 ft SSW swell with a 16-second period. The energy is moderate (823). It’s still cross-onshore, so it won’t be perfect, but with the light wind, it’ll be the cleanest surf of the entire forecast – small, clean, and long-period. It’s a long way off, so don’t bank on it, but it’s the only thing that looks even half-decent.

So, for the whole 16 days, there’s no standout. The best of a bad bunch is that small, clean SSW swell on Saturday the 19th. The rest is a mix of wind-affected chop and small, weak waves. There’s a lot of energy in that first week, but the wind just ruins it entirely.

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.
