The Lowdown
G’day, Rusty here. Let’s suss out what Dee Dees is offering over the next couple of weeks.
We’re starting off with a bit of a stinker. Thursday the 10th and Friday the 11th are a total mess – choppy, lumpy, and not worth a paddle. The water’s at 13°, a touch warmer than usual for this time of year, so at least you won’t be shivering while you wait.
The first real standout is Saturday the 12th. The morning session is a beauty – 1.7m groundswell from the SSW, with a 16-second period. That’s long-period energy, meaning real shape and power. The wind is glassy, dead flat, so the surface will be perfect. The combined energy is 1380 (moderate-to-strong), and this is excellent for experienced surfers. Beginners might find it a bit much at over 1.5m. Saturday afternoon, it pumps up to 3.0m from the SSW, with a light cross-shore breeze. The energy jumps to 2933 (strong), but that size is only for the experts. Crowds are possible here, so get in early.
Sunday the 13th is still hefty. The morning has 2.2m SSW swell, 13-second period, and a light cross-onshore breeze. Energy is 1525 (strong) – big and powerful, only for the skilled. The afternoon drops to 1.9m, but the wind turns onshore and it gets choppy, so it’s a bit iffy.
Monday the 14th is a ripper. The morning is clean, with 1.7m SSW swell, 12-second period, and a light cross-offshore breeze. Energy is 819 (moderate). The afternoon is glassy again, with 1.5m from the S, 11-second period, and 582 energy. Perfect for intermediates and up – clean, fun waves.
Tuesday the 15th morning has a smaller 0.9m SW swell, but it’s clean with a light cross-offshore. Energy is a low 208 (weak), so it’s a fun little wave for the patient. The afternoon gets messy with a 1.8m NW windswell, short 6-second period, and a cross-chop – not good.
From Wednesday the 16th through to Tuesday the 22nd, it’s a mixed bag. Most of the time, the wind is too strong or cross-onshore, and the swell is ragged. There’s a window on Sunday the 20th morning with a 2.5m SSW groundswell, 14-second period, and clean cross-offshore wind. The energy is huge at 2503 (strong), but that’s strictly for the pros – too big for most. The afternoon sticks at 2.4m with a cross-shore breeze, still big and heavy.
The best of the rest is Tuesday the 22nd morning – 1.3m from the S, 11-second period, clean with a light cross-offshore. Energy is 438 (moderate). A solid, surfable wave without the drama.
The last week of the forecast is mostly a dud, with tiny swells and strong winds. But hold on – Friday the 25th afternoon suddenly throws up a 4.0m SSW swell, with a 9-second period and a clean, light cross-offshore wind. The energy is 2662 (strong). That’s a massive, powerful swell, but with a short period, it’ll be a bit walled up and heavy. Only for the very experienced. After that, the forecast wraps up.
So, the standout is Saturday the 12th morning – glassy, 1.7m, long-period groundswell, and clean. The second pick is Monday the 14th, with a full day of clean, well-shaped waves. After that, it’s a waiting game.
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.
