The Lowdown
Hey, Rusty here again. Let's talk about Dee-Dees in feet and Fahrenheit, but don't worry, the story's the same.
We're in for a slow start. Tuesday the 15th and Wednesday the 16th are a total washout with tiny, weak surf and poor winds. Nothing doing. Thursday the 17th brings a 4ft swell from the NW, but it's short period at 5 seconds and the wind is messy, so it's not worth the paddle. Friday the 18th has a glassy window in the afternoon with waves around 2ft, but it's just too small to be fun. Saturday the 19th shows some energy with a 6ft SSW swell, but the period is short (7 seconds) and the wind is light cross-onshore, making for bumpy conditions. Sunday the 20th is a total loss with fresh onshore wind and rain.
Now, here's the one to remember. Monday the 21st of September is your day. We've got a solid 6ft SSW groundswell with a long 15-second period, pumping 1498 units of energy. The wind is a light cross-offshore breeze from the north, keeping the surface glassy. For experienced surfers, this is going to be a classic Dee-Dees session: powerful, clean lines, and plenty of push. The long period will have the sets stacking up, and paddling out will be manageable between the sets. It's going to be a bit much for beginners, but the rest of you will be frothing. Expect a crowd, though, because everyone will know about this one.
Tuesday the 22nd gets a bit hairy. The swell jumps to 8ft from the SSW, and even though the wind is light, the forecast says it's too big for the break. That's expert-only, big-wave territory.
Wednesday the 23rd is just a monster. We're looking at 18ft to 20ft SSW swells with strong onshore winds. That's over 9000 units of energy, but it's just a washing machine. Stay on the beach. Thursday the 24th is still too big at 8ft from the south, with the same warning about it being oversized for the break.
Things settle down towards the end of the month. Sunday the 27th morning looks decent with a 6ft NW swell and clean cross-offshore winds. The period is short, so it won't have the same punch as the 21st, but it'll be clean and fun for a session. The afternoon, however, jumps back up to an 8ft SSW swell that's again flagged as too big.
So there you have it. The standout is Monday the 21st. That 6ft, 15-second SSW groundswell with clean wind is the one you want to be on. Everything else is either too small, too windy, or too big. Don't sleep on that Monday.
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.
