The Lowdown
Alright folks, Rusty here. Let’s break it down.
First week is a bit of a write-off. You’re looking at a bunch of days with howling northwesterly winds and just ugly surf. You’ll be waiting until at least Monday, September 8th, before we even have a sniff of anything rideable.
Monday, September 8th at Dee Dees is the first light at the end of the tunnel. The swell is a tiny 3ft from the SSW, nothing to write home about. But the wind is light and offshore from the ESE, so the surface will be glassy. Total wave energy is weak (200), so it’s a small-wave day for the longboard or a fun egg. It’s not a standout, but it’s clean.
Tuesday, September 9th is even smaller, with a 2ft south swell and clean conditions again. Then we’re back into a windy, messy stretch through Thursday.
Now, Friday, September 12th and Saturday, September 13th see the swell jump up hard, with 10ft to 11ft SSW swells and huge energy (3092 and 4912). The problem is, it’s flagged as too big for this break. The wind on Saturday is also cross-onshore. This window is for seriously experienced big-wave chargers only.
The one day that shines is Tuesday, September 16th. This is your pick. A solid 7ft SSW groundswell with a nice 11-second period will push through. The morning goes glassy – dead flat calm – then swings to a light offshore breeze from the north in the afternoon. The combined swell energy is over 1000 (1044), and the water’s a little warmer than usual for this time of year at 56°. This is a clean, powerful day, but it’s best left for the experienced crew. Crowds are sometimes an issue here, and on a day like this you’ll have company.
Later, Saturday, September 20th shows a staggering 23ft to 26ft SSW swell with an incredibly long 16-17 second period. The energy readings are astronomical (35326 and 61593), but it’s too big for any reasonable paddle session. That’s a boat day or a cliff-watching day.
Your best bet? Circle Tuesday, September 16th at Dee Dees. That’s the day.
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.
