The Lowdown
Alright, let’s talk waves. It’s been quiet, but there are a couple of windows worth setting the alarm for. Dee-Dees is the only spot on the cards, so let’s see what we’ve got.
The first half of the week is pretty grim, lots of flat or junky days. You’ll be doing a lot of watching.
The real action kicks off early Saturday morning, September 12th. Water temp is a touch warmer than normal at 56°F. There’s a clean 5ft SSW swell with a long 15-second period, and the energy is moderate at 1087. Winds are light and cross-off, so it should be glassy perfection. This is the standout of the first week – a proper reef break with that long-period groundswell making it hollow and fast. It’s for the experienced crew, for sure.
Saturday afternoon, the swell jumps to a massive 12ft from the SSW, and the energy goes off the charts to 5777. That’s way too big and raw for this break. Even with light winds, it’s an expert-only zone, and most people will be on the beach.
Sunday, September 13th, is still huge at 8ft with a strong 1766 energy, but the wind is cross-on and lumpy. Another one for the pros, and the onshore breeze will chop it up.
Monday and Tuesday ease back down to the 3-6ft range, with moderate energy, but the wind is inconsistent. Monday’s a bit cross-chop, but Tuesday morning clears up with a 3ft S swell, a 10-second period, and light cross-off winds. A smaller, more relaxing option – a chance for a fun, uncrowded surf.
Wednesday, September 16th, is small and clean with a 3ft SSW swell and offshore winds, but it’s very ordinary. Thursday turns messy again.
The following weekend has a little something. Sunday, September 20th, afternoon brings a glassy 5ft S swell, but the period is a weak 7 seconds. The energy is a modest 302, so it’ll be a bit gutless and lumpy. It’s surfable, but not memorable.
Here’s the real treasure. Tuesday, September 22nd, morning has a clean 3ft SSW swell with a 15-second period, light offshore winds, and glassy conditions. The energy is low at 340, but that long period will give it real push and shape on the reef. This is the one to mark on the calendar – a long-range promise that could deliver some beautiful, lined-up waves. The North winds are offshore, so it should be working. It’s a small day, but the quality will be top-notch with no crowds.
The very end of the window stays alive. Wednesday, September 23rd, morning has a 5ft S swell with a short 6-second period, but the wind is true offshore from the ENE. It’ll be clean, but that short period is a bummer. Thursday, the 24th, is back to onshore junk.
So, for the best bets: Saturday morning, September 12th is your big, clean, long-period swell for the experienced surfers. And that Tuesday morning, September 22nd, is the hidden gem – clean, glassy, and just you and the reef. The rest is a waiting game.
Rusty out.

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.
