The Lowdown
G’day, Rusty here. We’ve got a mixed bag at Dee Dees over this 16-day stretch. Right now, the water’s sitting at 56° – a touch warmer than normal for this time of year, so you won’t need the thickest rubber. The first surf worth paddling out for is this Friday morning, 11th September. It’s small, only 3 ft from the SSW with a solid 17-second period – that’s proper long-period groundswell, so it’ll wrap in with some push. Combined energy is moderate at 440, and with a clean cross-off breeze from the NNW, it’ll be glassy and lined up. Just a heads up, it’s a reef break, so the long period will make it a bit more straight at the take-off, but still fun for intermediates. Crowds can show sometimes.
Friday afternoon drops off quick – 1 ft and a messy cross-shore chop, so I’d skip it.
Saturday morning, 12th September, is where it gets cracking. Swell jumps to 6 ft from the SSW, still 15 seconds period, and the combined energy is pumping at 1486 – that’s moderate-strong. The wind is light and cross-off from the ESE, making it clean as a whistle. This is excellent for experienced surfers. It’s not too big yet, so you can work the reef without it being a washing machine. Best option so far.
Saturday afternoon sees 10 ft – that’s big, too big for this setup. The break gets overwhelmed, and it’s only good for experts if anyone even bothers. I’d give it a miss unless you’re chasing a real challenge.
Sunday morning, 13th September, delivers 7 ft from the SSW with clean offshore wind from the WSW. Again, that’s pushing the limit for Dee Dees, so it’s expert-only territory. Combined energy is 1543. The swell drops to 6 ft Sunday afternoon but picks up a cross-shore breeze, so it’s only marginal.
Monday morning, 14th September, is a sweet spot. 6 ft from the SSW, 12 seconds, combined energy 1047 – solid moderate energy. Wind is light and cross-off from the north, so it’s clean. Perfect intermediate-to-expert window. Monday afternoon gets glassy – 6 ft from the south with zero wind. That’s a rare treat. The swell period drops to 12 seconds, but the glassy surface will make every wave feel like a dream. That afternoon session is the standout for the first week.
Tuesday, 15th September, is smaller – 3 ft in the morning, 3 ft in the afternoon – both clean but weak. Wednesday the 16th is blown out with gale-force winds, and Thursday the 17th is a mess of rain and short-period chop, though Thursday afternoon cleans up with 5 ft and a light cross-off – worth a quick look if you’re desperate.
The second week goes from rough to massive. Friday 18th through Sunday 20th September remains small, poor, or blown out by strong winds. Then Monday 21st to Wednesday 23rd is all strong cross-onshore winds and lumpy waves – not worth getting wet for.
But then… Thursday 24th September pumps up to 15 ft from the SSW, 11 seconds, combined energy a massive 7723. That’s huge. But the file says it’s too big for this break – only for absolute experts, and even then, it’ll be a beast. The wind is moderate cross-shore, so it won’t be clean. Friday 25th and Saturday 26th are similar – 13 ft and 8 ft respectively – all too big and lumpy. If you’re a seasoned charger, you might find a wave, but for most, the setup looks more interesting for kite surfing than paddle surfing by that point.
Overall, the real standouts are Monday 14th September – both morning and the glassy afternoon – and Saturday morning 12th September. Those are the ones I’d be circling on the calendar.
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.
