The Lowdown
G’day, Rusty here, and I’ve got the scoop on the waves at Dee Dees for the next couple of weeks. It’s a bit of a mixed bag, so let’s get into it.
Right off the bat, August 23rd is a write-off – Sunday morning’s got rain showers and a messy 28 mph cross-shore wind, with only a tiny 1ft S swell. The water’s sitting at 53°F, which is pretty much bang on average for this time of year, so nothing to write home about there. The afternoon’s no better, with a cross-on breeze and a weak, short-period 7ft NW windswell. Surf’s basically non-existent.
There’s a gap of a few days with no real recommendations until the 26th. Wednesday morning, the 26th, is a glimmer of hope. The wind swings light from the NNW, giving us a clean, cross-off breeze. The swell is a modest 4ft from the SSW, but with a lovely 14-second period – that’s proper groundswell, boys. Combined energy is moderate (486). It’s not massive, but it’s clean and rideable.
Then we hit a big ugly stretch. From the 27th right through to the 31st, it’s mostly poor conditions. Strong winds, messy chop, and lumpy seas. The 31st sees a 10ft SSW swell roll in, but with a strong cross-on breeze, it’s just a washing machine. On the 31st afternoon, the wind eases a bit, but that swell is still too big for Dee Dees – over 8ft, so it’s expert territory only. Combined energy is massive (2402), but the wind’s still cross-on, making it choppy.
Now, here’s where it gets interesting. The real standout is Thursday, September 3rd. The morning is a gem – light winds from the north, glassy clean conditions, and a 3ft SSW swell riding in on a 19-second period. That’s a very long period groundswell, which means long, lined-up waves. Combined energy is moderate (635), but the quality is what counts. The afternoon holds up too, with a 3ft SSW swell and 15-second period, still clean. This is the best on offer – a true short window of excellence.
After that, the 5th of September Saturday morning brings a surprise: a 6ft NW swell with glassy conditions. The period is only 6 seconds, so it’s a bit of a short-period windswell, but man, it’ll be clean and fun. Combined energy is low (279), but the glassy texture makes it a really good option. It’s a bit of a one-off, but worth getting up early for.
The second week gets wild. The 6th of September Sunday sees a massive 20ft SSW swell, with combined energy hitting 10343 – that’s strong to very strong. But it’s a total mess with 25 mph cross-shore winds. That’s big, dangerous, and ugly. The 7th Monday morning brings a 8ft SSE swell, with a clean cross-off breeze, but that size is only for experts. Combined energy is 1447.
So, bottom line: the best windows are the morning of September 3rd and the morning of September 5th. The 3rd is the true standout for quality, clean waves, while the 5th offers a glassy session on a smaller, short-period swell. Everything else is either blown out, too big, or just plain messy. Keep your eye on the forecast, though – it never stays bad for long around here.

Information about the Dee Dees Surf forecast
The above surf forecast table for Dee Dees provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Dee Dees can be found by selecting the local surf guide option on the grey menu. Our Dee Dees 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 (Dee Dees) 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 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.
