The Lowdown
Alright, Rusty here. Let's break down what's happening at Dee Dees.
For the next week or so, it's a bit of a battle. We've got the swell coming in, but the wind's going to be a handful. Water temp is around 53°F, which is just about average for this time of year, so nothing crazy there.
Your best chance in that first week is on Thursday, the 27th of August. The morning brings a light offshore breeze from the east, and a solid 7ft swell with a long 17-second period from the SSW. That's serious energy – combined energy sits at 2680 – and the surf will be clean. This is a reef, so that long-period groundswell will line up nicely. Just keep in mind, 7ft is starting to push it, so this is for the solid intermediates. The afternoon stays good with offshore winds from the NE and a 7ft swell at 15 seconds. This is the one to aim for.
Saturday the 29th and Sunday the 30th are small and sloppy, not worth the effort. Monday the 31st of August brings a big jump to 10ft to 12ft from the SSW, with energy readings over 5000. That's a lot of water moving, but the cross-shore wind will chop it up. Too big and too messy unless you're an expert, and even then the wind is a problem.
The start of September is rough. Tuesday the 1st still has that big 10ft to 12ft swell, but the cross-shore wind is still there. By Wednesday the 2nd, a near gale from the NW destroys the 6ft swell. The rest of the first week of September is a write-off with strong, messy winds.
There's a faint hope on Sunday the 6th of September with 6ft from the SSW and a light cross-shore breeze, but the period drops to 7 seconds, so the waves will lack power and shape. It's barely worth a look.
Then things go quiet. Tuesday the 8th of September has clean offshore winds from the NE, but the swell drops to a tiny 2ft with weak energy (110). You could get wet, but it's pretty ordinary. By Wednesday the 9th, it's all but gone.
So here's the bottom line: Thursday the 27th of August is your day. Clean offshore wind and a proper groundswell. The rest of the forecast is mostly waiting on the wind to behave or the swell to show up.
Rusty, signing off.

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 Dee Dees 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.
