The Lowdown
G’day, I’m Rusty. Let’s have a look at what’s on offer down at Dee Dees for the next 16 days.
Right off the bat, things are looking pretty average for the most part. The water temp is sitting at 53°, which is about bang on normal for this time of year, so nothing wild there. The early part of the window is basically a write-off, thanks to messy winds and poor conditions. We’ve got a long stretch of pretty ordinary days ahead, so don’t expect much until we get into the back half of the first week and beyond.
Thursday the 23rd morning kicks off with a tiny 2 ft SSW swell, period of 12 seconds, and a light NNE cross-off breeze. The wave energy is moderate (117). It’s clean, but it’s small – you’d be scratching for a wave. That afternoon, things go downhill fast with a 35 km/h NNW cross-wind making a mess of a 5 ft NW swell. Friday the 24th is more of the same: lumpy cross-shore chop and poor surf. Saturday the 25th is a write-off, with a strong 45 km/h SSW cross-on wind and a 13 ft SSW swell that’s way too big, messy, and dangerous – definitely not for paddling. The combined energy that morning is a moderate 120, but by afternoon it’s a massive 1939 – that’s a lot of power, but with the wind, it’s a total dog.
Sunday the 26th morning sees a drop in wind to a light 10 km/h cross-on, with a 5 ft S swell at 8 seconds and moderate energy (466). It’s still marginal, but at least it’s not a complete howling mess. The afternoon clears up with a light onshore breeze and a 4 ft S swell, energy down to 275 – still just marginal. Monday the 27th and Tuesday the 28th mornings are still poor and marginal, but there’s a glimmer on Tuesday afternoon: glassy conditions with a tiny 2 ft ESE swell, but the period is a long 13 seconds. The wave energy is moderate (240). It’s not much, but it’ll be clean. Wednesday the 29th morning sees a 2 ft ESE swell, 13-second period, with a light NNE cross-off breeze and clean conditions. Combined energy is moderate (289). That afternoon, the swell switches to SSW at 2 ft, with a 14-second period, energy jumps to 425 – still clean. That’s probably the best you’ll get in the first week: small but tidy.
Now, Thursday the 30th and Friday the 31st are back to poor conditions with strong cross-winds and messy chop. The real standout, if you’re brave enough, is Saturday the 1st of August. The morning brings a 10 ft SSW swell, period 8 seconds, with a light NNE cross-off breeze and clean conditions. The combined energy is a massive 1142 – that’s strong. But mate, 10 ft is big – this is only for experts. The afternoon blows out to 16 ft with a 10-second period, energy at 4661 – that’s very strong wave energy. It’s too big for this reef break, so unless you’re on a gun and know what you’re doing, stay away. The wind is light, but the size is the issue.
After that, Sunday the 2nd of August through to the end of the window on the 7th of August is mostly a write-off: strong cross-on winds, big to moderate swell, and poor conditions. The energy levels stay high, but the wind kills it. Monday the 3rd morning has a 4 ft SSW swell, 9-second period, with a gentle cross-shore breeze and energy of 534 – it’s marginal, but not worth paddling out for.
Overall, don’t hold your breath for the first week. The best clean, small surf comes on the 29th, and if you’re an expert, the 1st of August has serious size but it’s the real deal. For everyone else, it’s a long wait.
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.
