The Lowdown
Alright, Rusty here. Let’s talk about what’s brewing for Dee Dees.
We’re looking at a pretty grim start to this 16-day run. The first few days are a write-off – strong winds and messy, poor surf just aren’t worth paddling out for. The first real glimmer of hope comes on Monday, September 7th. Dee Dees is a reef break, fairly consistent, exposed to the south swell, and it needs that clean cross-off wind. Monday morning the wind is a light cross-off from the ESE, and the swell is 5 feet from the S with a period of 7 seconds. The combined energy is moderate (249). The water temp is sitting at 55°, which is about 2° warmer than usual for this time of year – nothing wild, but a nice touch. It’s a marginal call, but the afternoon cleans up even more with a gentle breeze and the same 5-foot S swell, looking cleaner. That’s your best bet early on.
We get a bit of a bump mid-week, but Wednesday the 9th sees a glassy afternoon with a clean 3-foot S swell, period of 8 seconds – absolute butter conditions, but the wave size is small. The energy is light (146). It’s surfable, but ordinary.
Then things get messy again. Thursday the 10th is a write-off, and Friday the 11th brings a massive 13-foot SSW swell (energy of 2871). The wind is cross-on and strong, so it’s messy and lumpy. That afternoon, the swell drops to 10 feet and the wind goes light, but the break is predicted to be too big for Dee Dees. That’s a big red flag – only for the experts, and even then, it’s a beast.
The absolute standout is Wednesday, September 16th. We’ve got a glassy morning with a 13-foot S swell, period of 14 seconds – that’s long-period groundswell. The combined energy is massive (6383). The wind is dead calm, making for perfect conditions. But the swell is over 8 feet, so this is strictly for experienced surfers. The afternoon gets even bigger: 20 feet S swell with a 15-second period and an energy reading of 16422 – that’s seriously heavy. Again, too big for this break, but if you’re a charger and the conditions hold, that’s a session you’ll remember. The caveat is that long-period swell like this can break a bit straight on a reef, but Dee Dees is a reef, so it should handle it.
The following weeks see a lot of poor conditions, with a clean window on Saturday, September 19th. That morning offers a 4-foot SSW swell, period of 14 seconds, with a light cross-off from the north, making for clean conditions and a moderate energy of 605. That’s a promising, but less certain, long-range option.
So, to sum it up: Monday the 7th is a quiet, clean start for the confident surfer, but Wednesday the 16th is the big-ticket item – a massive, glassy groundswell that’s only for the experts. The rest of the window is mostly messy.
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.
