The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on the cards for the Dee Dees region over the next couple of weeks.
Right off the bat, I have to be straight with you – the next week and a half is looking pretty grim. We’ve got a long, slow grind of poor conditions ahead. The good news is that things might finally turn around towards the end of the period, but you’re going to need some patience.
Starting from Saturday, the 29th of August, we’ve got small, weak swell pushing in from the south. The water temp is sitting at 54°, which is about normal for this time of year, so no surprises there. The waves are only around 3 ft with a south swell, but the wind is a cross-shore, and the overall energy is weak (233). The comment says it all – poor surf conditions. Sunday and Monday are much the same story: small, crummy swell, cross-shore winds, and just not worth getting wet for.
Then we hit a period where the swell gets some serious size, but it’s all wrong for us. From Monday the 31st of August through to Wednesday the 2nd of September, we’re looking at a solid south-southwest groundswell, with heights climbing from 8 ft to a massive 13 ft. The wave energy is through the roof – we’re talking values over 1700 and up to 7819 – so there’s plenty of power. But the wind is cross-onshore, and the comments keep saying the swell is too big for this break. This is expert-only territory, and even then, the conditions are going to be choppy and messy. For the average punter, this is a no-go.
After that, the swell drops back, but the wind doesn’t cooperate. From Thursday the 3rd of September right through to the middle of the following week, we’re stuck with a cross-shore breeze that’s blowing anywhere from a fresh to a strong breeze. The wave heights are all over the place, from a tiny 0.7 ft up to 6 ft, but the quality is consistently poor. The energy is weak to moderate, but it’s just not coming together. There’s a real gap in quality surf here.
Now, here’s where it gets interesting. After a long stretch of nothing, we finally see a glimmer of hope on Thursday the 10th of September. The morning session is looking promising with a glassy, clean surface and a light air. The swell is small at 6 ft, coming from the northwest, and the period is short at 6 seconds, so it won’t have much grunt, but it’s going to be smooth. The combined energy is weak (224), but the conditions are right for a fun, clean wave. Friday the 11th of September morning is much the same – glassy, clean, with a 5 ft west-northwest swell. This is your window to get a few nice, clean rides while the wind is off.
The standout session, though, is shaping up to be Friday the 11th of September afternoon. The swell is jumping up to 12 ft from the south-southwest, with a period of 9 seconds and a combined energy of 1634 – that’s serious power. The wind is light and cross-onshore, but the comment suggests the tide and wind are favourable. This is a big, powerful swell, so it’s for experienced surfers only. If you’re comfortable in that size, this could be the best wave of the whole forecast period.
After that, things go a bit pear-shaped again. Saturday the 12th of September sees strong onshore winds and messy conditions, and Sunday the 13th of September is only marginal. So, if you’re looking for a session, focus on that Thursday and Friday morning glass, and keep an eye on that Friday afternoon when the big south swell hits.
Stay patient, and keep your fingers crossed for the long-range stuff.
Rusty.

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.
