The Lowdown

Alright folks, Rusty here. Let's talk about what's shaping up at Dee Dees. It's a bit of a mixed bag, so let's break it down day by day.

We're starting off on Monday the 10th of August, and honestly, it's a quiet beginning. The waves are tiny, coming in at about 2ft from the south, with a short period of 10 seconds. There's hardly any energy behind it (115) and a cross-on breeze is making things messy. Not worth paddling out for.

Tuesday the 11th sees a bit of a pulse. The morning picks up to about 6ft from the south, but the period drops to just 8 seconds, making it a bit junky and still cross-on. The afternoon is where it gets a little interesting. The swell drops back to about 5ft from the south-east, but we get a clean, cross-off wind. The wave energy is moderate (301). It's not a standout, but it's the first real window for a surf.

Wednesday the 12th and Thursday the 13th are small. We're talking waist-high or less with weak energy (43-68). The winds are clean, but there's just not enough push. Friday the 14th is completely flat.

Now, here's where things get a bit gnarly. Saturday the 15th, the swell bumps back up to about 5ft from the south-west, but the period is a short 6 seconds, and rain moves in. The morning is clean but weak, and the afternoon gets messy with strong cross-shore winds. Not good.

Sunday the 16th is a write-off. A massive 12ft south-southwest swell rolls in, but it's accompanied by screaming winds near 31 mph and heavy rain. The combined energy is huge (1706), but this is purely a survival mission, not a surf session. It's blown out and dangerous.

Monday the 17th and Tuesday the 18th stay big and messy. We're looking at 10ft to 12ft south swells with strong cross-shore winds. The energy is through the roof (2079), but the conditions are chaotic and the swell is too big for most. For a beach-reef setup like this, it looks way more interesting for kite surfing than paddle surfing unless you're a seasoned charger.

Wednesday the 19th settles down a touch but remains large at 7ft to 10ft from the south. The winds are lighter but still cross-on. The energy is still massive (1398-1466). The tide calculations are questionable, so this is still one for experts only.

Now, let's talk about the real standout of this outlook. Thursday the 20th of August. The swell drops to a much friendlier 5ft from the south (9 seconds period) with moderate wave energy (455). But the magic is in the morning: the wind goes glassy – dead calm, as smooth as butter. That’s rare, and it’s going to give Dee Dees some clean, lined-up waves before the light SE sea breeze kicks in for the afternoon, which stays clean and cross-off.

But if you want the absolute best session on offer, you have to look to Friday the 21st of August. The morning has a solid 4ft south swell (13 seconds) with clean cross-off winds. The afternoon, though… This is the pick. The swell builds to 5ft, the period stretches to a beautiful 14 seconds from the south, and the wind goes glassy again. The combined energy jumps to very strong (1177). This is a proper groundswell with excellent shape. Because it’s a reef break, the long period will wrap in nicely. It’s going to be clean, powerful, and have those long waits between sets—perfect for the intermediate to experienced surfer with good positioning. This is your date with Dee Dees.

After that, things drop off again. The weekend of the 22nd and 23rd offers clean but much smaller surf with shorter period swells. By Monday the 24th and Tuesday the 25th, we're back to tiny, weak waves.

So to sum it up: you have a long wait. The first half of the window is either flat, blown out, or just too big and messy. The real gold is on Thursday 20th morning for glassy conditions and, the crown jewel, Friday 21st afternoon for the best combination of size, clean winds, and long-period groundswell. That’s the one to clear your calendar for. It’s a promise, but it’s a good one.

Rusty.

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.
