The Lowdown
Hey, it’s Rusty. Let’s break down Dee Dees – a reef break that loves a solid south swell. The water’s sitting at 55°F, about 2°F above the norm for this time of year, so it’s a touch warmer than usual – not a bad thing.
We start Sunday the 13th with a 7ft SSW swell, period at 13 seconds – that’s proper groundswell energy, reading 1455 (moderate to strong). Wind’s light cross-onshore from the west at 6 mph, but the wave comment says it might be a bit too big for this spot. Only for the brave.
Monday the 14th is the real deal. Morning is glassy – wind from the north at 3 mph – and we’ve got a 6ft SSW swell at 12 seconds. Combined energy 1064. Clean, organized, and the guidance says it’s excellent for experienced surfers. I’m calling this the best of the run. The afternoon glass-off with a 6ft S swell is a sweet bonus.
Tuesday the 15th drops off. Morning is a clean 4ft S swell at 10 seconds with a light cross-offshore breeze – combined energy 320. Afternoon glassy with 2ft SSW. Still surfable but weaker.
Then we hit a dead zone. Wednesday the 16th through Friday the 18th is mostly poor. Wednesday morning has a 7ft NW windswell with 19 mph cross-wind – messy. The rest is tiny or blown out.
Saturday the 19th morning throws a 10ft S swell at 7 seconds – combined energy 895 – but that short period and the wave comment says it’s too big for the reef. Afternoon brings 8ft SSW at 8 seconds. Experts only.
Sunday the 20th is a nice reset. Morning has 4ft SSW at 14 seconds – long period, clean with a light cross-offshore from the southeast. Combined energy 717. Nice lined-up sets.
Monday the 21st is small – 3ft SSW in the morning, cross-offshore breeze. Energy 218. Easy cruising.
Tuesday the 22nd turns ugly – 10ft SSW windswell with 28 mph cross-onshore wind. Blown out. Energy 1420 but useless.
Wednesday the 23rd has 6ft SSW at 17 seconds – very long period – but onshore wind at 3 mph, and the wave comment says marginal. Energy 1828, but wind kills it.
Thursday the 24th morning is another standout – glassy with 4ft SSW at 16 seconds. Combined energy 765. Clean groundswell, long walls. For the experienced crew.
After that, it’s mostly poor from Friday the 25th onward – strong winds, messy conditions, tiny swell.
Best of the 16 days is Monday the 14th morning – glassy, 6ft groundswell, that reef will be firing. Honorable mention to Thursday the 24th morning – glassy, 4ft, long-period lines. Beginners should look at Monday the 21st for small, clean waves.
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.
