The Lowdown
Right then, let's get into it. We’re looking at Dee Dees, a reef break that’s fairly consistent and exposed to the south.
The long-range picture offers some real promise, but you’ll have to be patient because there’s a lot of poor conditions in the near term. The water’s sitting at 54°F, which is pretty normal for this time of year, so a good wetsuit is the go.
Monday, August 31st is a write-off. We’ve got a 8ft SSW swell but it’s being hammered by a strong cross-onshore breeze. The combined swell energy is moderate to strong (1862), but the wind is ruining it. Just don’t even look at the ocean.
Tuesday, September 1st brings a massive pulse of swell – we’re talking 15ft from the SSW. The combined energy is absolutely pumping (8735). The wind is lighter, cross-onshore, and the conditions are clean, but this is way too big for anyone except the most seasoned charger. The same goes for the afternoon, with 13ft and a long 13-second period.
Wednesday, September 2nd backs off to a still-sizeable 8ft, but the wind is cross and stronger. It’s still solid, still powerful, and that long period (13-15 seconds) from the south/southwest means groundswell. For the experienced crew this could be on, but the moderate to fresh cross-wind is going to chop it up.
Thursday September 3rd and Friday September 4th see the swell dropping below 4ft and the wind really howling, which means flat and messy. A couple of days to miss.
Saturday, September 5th offers the first real standout in this outlook. We’ve got a clean 4ft from the south in the morning with a light cross-offshore breeze from the north. The combined energy is weak (234) and the period is short (8 seconds), but for a reef break, that clean wind makes it super user-friendly. Not a big day, but a glassy, fun-sized wave. The crowds here can be a thing sometimes, but for a small clean wave like this, it should be a very pleasant session.
After that, it’s back to small, windy, and messy for the next few days.
Things look interesting again around Monday, September 7th, but that 12ft to 15ft SSW swell is too big and coming with strong onshore wind. It’s going to be a washing machine.
Wednesday, September 9th is a nice little session. The early morning has a clean 4ft from the south with a light cross-offshore. The afternoon goes completely glassy with zero wind and a 3ft south swell. Combined energy is very weak (111 and 186), so it’s small and slow, but glassy conditions on a reef are a special thing. It’s ordinary-sized waves, but in perfect conditions.
Friday, September 11th looks promising for the bigger-wave crew. A 7ft SSW swell (combined energy 1055) and clean cross-offshore wind. That’s a fair bit of power, but the wind is light and clean. The period is a solid 10 seconds. If you’re charging, this could be the pick.
Sunday, September 13th is back to small and windy, so don’t get your hopes up.
The last real standout is on Monday, September 14th. A 5ft S swell with a long 12-second period and light cross-shore wind. The energy is moderate (1080). It’s a marginal call, but that groundswell on a reef will produce some nice lines, and the light wind makes it surfable.
Finally, Tuesday, September 15th is another huge pulse – 7ft from the south with a very long 15-second period and clean cross-offshore wind. The combined energy is very strong (3077). This is another one for the experts only; that’s a powerful, clean groundswell on a reef.
So, to sum it up: for a clean, easy session, you can’t go past the glassy September 9th. For the experienced surfer hunting power, the 11th or 15th of September are the standout windows.
Stay stoked,
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.
