The Lowdown
Alright, Rusty here. Let’s break down what Dee Dees has cookin’ for the next couple weeks.
First few days are a total dud. Wednesday and Thursday are tiny, weak, and blown out. We’re looking at combined energy from 50 to 175, so just nothing happening. Leave the board at home.
The first real chance comes Friday morning, September 11th. Clean cross-off breeze from the north, and a long period groundswell of 18 seconds from the SSW. The waves are only 2 feet, but the energy is a solid 385. That long period means the waves will be well-shaped and the paddle out is easier. It’s a mellow start, but a good one for a longboard.
Now, the standout window is Saturday afternoon through Monday morning. Saturday afternoon, September 12th, is glassy calm with a light north wind. The swell jumps to 10 feet from the SSW at 13 seconds. The combined energy is a massive 4672 – that’s strong. But that’s just too big for Dee Dees. It’s an expert-only wave if you’re brave. Clean, but a beast.
Sunday stays oversized, 10 feet to 8 feet, but the wind is messy. Not the best.
The real sweet spot for the experienced surfer is Monday morning, September 14th. The swell drops to 7 feet, still from the SSW at 12 seconds, and the wind is a clean cross-off from the north. The energy is a solid 1254. That’s excellent, clean surf for those who know what they’re doing. Beginners should stay far away.
Water temp is about average for the time of year, nothing special.
After Monday, it goes downhill fast. Strong winds, blown-out conditions, and a lot of poor surf. Tuesday afternoon has a stiff breeze of 28 mph, and by the end of the week, we’re looking at near gale-force winds. There’s a massive 13-foot swell on Tuesday, September 22nd, but that’s way too big and unsurfable here.
In the second week, the only faint whisper is Thursday morning, September 24th. A clean cross-off, but the swell is only 2 feet with a long 16-second period. Combined energy is just 185 – weak. It’s a session for the log.
Overall, the best on offer is clearly Monday morning, September 14th. That’s your standout. For the brave, Saturday afternoon is a gnarly, glassy challenge. The rest is a long stretch of junk. Don’t force it.
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.
