The Lowdown

G’day, Rusty here. Let’s have a proper look at the Dee Dees region over the next couple of weeks.

Right off the bat, it’s a tough start. We’ve got a long stretch of poor surf ahead, with nothing worth paddling out for on Wednesday 12th, Thursday 13th or Friday 14th August. The swell is tiny – around 0.7ft to 1ft – and even when there’s a bit of energy, the conditions are ordinary. The water temp is about normal for this time of year, so no surprises there.

Saturday 15th August morning is glassy, but the swell is only 0.7ft with a very long 17-second period – that’s a groundswell, but it’s just too small to do anything with. The combined energy is a weak 54, so it’s really just a flat day. The arvo brings a bit more size but cross-onshore wind and rain, so no good.

Sunday 16th August we see a jump in size – 8ft in the morning – but the period is short at 8 seconds and the wind is a strong cross-shore. Combined energy is 991, which is moderate, but it’s messy. This is expert-only territory if you’re keen, but the cross-chop makes it a write-off for most.

Monday 17th August morning has 8ft but a 6-second period – that’s windswell, short and weak. The arvo is a little better at 6ft with offshore wind, but the tide and swell quality are questionable. Combined energy is 747, still moderate but not clean.

Tuesday 18th August is more of the same – 6ft to 8ft, cross-onshore, short period, choppy. Nothing to get excited about.

Now, here’s where it gets interesting. Wednesday 19th August morning sees a massive 16ft S swell with a 16-second period – that’s a very long period groundswell. Combined energy is a whopping 11355 – that’s strong to very strong. The wind is light and offshore, so the conditions are clean, but the swell is way too big for Dee Dees. This is for experts only, and even then, it’s predicted to be too big for this break. The arvo is 12ft with the same issue. Thursday 20th August stays big at 10ft to 8ft, still too big and cross-onshore.

Friday 21st August has 7ft to 6ft S swell with 11-second period – still a decent groundswell, but the wind is cross-onshore and the tide is questionable. The afternoon gets a rating of 3, which is the best we’ve seen so far, but it’s still marginal.

Then Saturday 22nd August morning – this is the standout. The swell drops to 5ft from the south with an 11-second period, and the wind is a light cross-off from the north. Combined energy is 593, which is moderate, but the conditions are clean. The water will be about average for the time of year, and the crowd factor is “sometimes” so you might have a few out but it’s not packed. This is a solid option for intermediate surfers – the swell direction matches the optimum S direction and the break is a reef, so it should handle that long-period swell well. The arvo turns choppy with a moderate cross-onshore, so plan for the morning.

Sunday 23rd August morning is also good – 4ft S swell, 10-second period, light cross-off from the NNE, clean conditions. Combined energy is 354, so it’s weaker but still fun. The arvo again gets messy with a fresh cross-shore.

From Monday 24th August onwards, the surf drops off and the wind picks up – strong breezes, cross-shore, and the swell is small and weak. The combined energy stays below 400, and the conditions are poor. By the end of the month, it’s back to tiny swells and rain.

So, the call is: if you’re after quality, aim for Saturday 22nd August morning at Dee Dees. It’s the best on offer. Sunday 23rd morning is a good backup. The big swell mid-week is a spectacle but not for paddling.

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.
