The Lowdown
Hey, Rusty here. Let’s break down what Dee Dees is looking like. It’s a reef setup that’s fairly consistent and open to the south, so when the right swell shows, it can be a good one. The water temp is about 54°F, right around normal for this time.
We’re in a bit of a holding pattern. The first real action is Thursday, August 27th, with a 7ft south swell, a long 16-second period, and a combined energy reading of 2247 (moderate to strong). The wind is a light offshore from the northeast, so it’s clean, but this is serious – only for the experienced. The energy is there, but it’s a heavy reef.
Then it’s a few days of nothing. From Friday the 28th through Sunday the 30th, it’s a mess of cross-shore winds and dropping swell. A solid gap of poor conditions.
Here’s the main event. Monday morning, August 31st. Glassy conditions – dead calm wind from the north-northwest – and the swell is pumping at a huge 12ft from the south-southwest, 12-second period. The combined energy is a massive 3551 (strong). That’s a lot of power. But, for Dee Dees, that’s too big. The reef will be heaving, expert-only stuff. The glassy wind is a dream, but the size is the challenge.
Tuesday, September 1st, is another day of serious muscle: 12ft from the south with a 14-second period and an energy reading of 3844 (very strong). Same story – too big for this break, with onshore wind adding to the drama.
The rest of the first week and into the second is mostly wind-swept. Friday, September 4th, has a clean morning with a 3ft south-southwest swell, a 14-second period, and light cross-offshore wind. It’s surfable but small, with moderate energy at 434.
Looking way out to Friday, September 11th, there’s another pulse: 7ft from the south-southwest, 13-second period, energy at 1755 (moderate to strong). But the wind is a messy cross-shore, and the size is again pushing the limits for Dee Dees. A promising long-range signal, but far off and uncertain.
The standout is that glassy Monday the 31st, but only if you’ve got the skills. For the rest of us, it’s a waiting game.
Take it easy, 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.
