The Lowdown
Alright, Rusty here again. Let’s go through the same picture, this time in feet and Fahrenheit.
First up, Monday the 14th at Dee Dees has some real promise. A 6ft south swell with a 12-second period, and the energy is solid (800). Water temp is 55°F, right about average. The wind is glassy, dead calm from the south, so it’ll be clean as a whistle. That’s the standout session.
Tuesday the 15th is a bit all over the place. Morning swell drops to 4ft from the south with a messy cross-shore wind. The afternoon glass-off is onto a tiny 2ft from the SSE – clean but small.
After that, we’ve got a grim stretch from Wednesday the 16th through the end of the next week. Strong winds, choppy seas, and poor conditions dominate. The weekend of the 20th has light rain and weak energy (174 to 229).
Then the big stuff arrives. Monday the 21st of September: a 6ft groundswell from the SSW with a very long 15-second period. The combined energy is powerful at 1708. The wind is light and cross-offshore, so it’ll be smooth. This is for experienced surfers only – that long period makes the waves pack a punch.
Tuesday the 22nd and Wednesday the 23rd get huge – 10ft to 16ft from the SSW. Clean wind, but way too big for this spot. It says the waves will be too big for the break.
Friday the 25th is a nice recovery: 4ft to 3ft from the south, light offshore wind, and clean. A good day for an easy paddle.
The last few days of September get lumpy again with strong cross-shore winds. The 29th brings another big 7ft swell with a 14-second period, but the cross-shore wind will mess it up.
The call: Monday the 14th for clean, glassy fun. Monday the 21st for the real power, but it’s experts only. Friday the 25th for a relaxed session.

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.
