The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming our way for Dee Dees over the next couple of weeks.
Right off the bat, the first few days are a bit of a write-off. We’ve got small, weak swell and the conditions are just ordinary. Tuesday the 8th and Wednesday the 9th are not worth paddling out for.
Now, things start to get interesting on Saturday the 12th. The morning shows a 6ft swell from the SSW with a short period of 7 seconds and a moderate combined energy of 530. The wind is light and cross-off from the east, cleaning up the surface nicely. This is a solid call for an intermediate surfer. Then, Saturday afternoon the swell jumps to 10ft from the SSW with a very long period of 12 seconds. The energy is strong at 2500, but the swell is too big for this break. Only for the experts, and even then, it’s a big one.
The real standout window kicks off on Monday the 14th. Monday morning is glassy with a 5ft SSW swell, a period of 12 seconds, and a moderate energy of 703. But Monday afternoon is where it’s at. The wind is completely calm, making it glassy, and the swell holds at 5ft, but the period stretches to 14 seconds with a combined energy of 1029. This is the best on offer. Clean, powerful, long-period groundswell. Dee Dees is a reef break, so that long period will wrap in beautifully. Perfect for experienced surfers.
The water temperature is about average for this time of year, nothing out of the ordinary.
After Monday, the wind turns nasty. Strong and cross-shore from the NNW on Tuesday the 15th, which ruins the quality. The rest of the week is a mess of strong winds and blown-out conditions. The swell energy is still there, but it’s not worth it with the wind.
There’s a brief glimmer on Tuesday the 22nd with a tiny, clean 1.0ft swell from the SE, but it’s barely surfable.
So, in summary: the first half of the 16-day window is a dud, but Monday the 14th afternoon is your day. Get out there. Dee Dees is a fairly consistent reef, so it’s not a total blank run, but the window is narrow.
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.
