The Lowdown
Hey, it’s Rusty. Let’s talk about Dee Dees in imperial, because the numbers mean more that way.
The first few days are a rough go. Friday the 24th July: a lumpy 5ft NW windswell with 176 energy and a fresh cross-breeze – just nasty. Saturday the 25th starts tiny at 3ft (46 energy) and then blows out with a 10ft SSW swell (1196 energy) and strong cross-onshore wind – that’s kite-surfing weather, not paddling. Then Sunday the 26th morning turns it around. The wind goes dead calm, glassy, and we’ve got a clean 4ft S groundswell (297 energy). That’s your first real session – smooth, fun, good for intermediates.
Monday the 27th is small but glassy in the arvo with a 1ft, very long-period swell (155 energy) – a real glass-off. Tuesday the 28th keeps that long-period ESE groundswell around 2ft (193-232 energy), clean morning and glassy afternoon. Wednesday and Thursday the 29th-30th are back to messy, small, and not worth it.
Now the good stuff. Friday the 31st July morning: a clean 6ft SSW groundswell (726 energy) with a light offshore breeze – that’s your standout. Fun size, clean shape, perfect for intermediate surfers. The afternoon jumps to 8ft (1064 energy) and gets too big for the break – for experts only. Saturday the 1st of August is even bigger, 10ft (1662 energy) and then a massive 10ft again (3126 energy), all too big. Sunday the 2nd drops back to a clean 5ft S swell (453 energy) in the morning with an offshore breeze – solid backup.
Second week gets wild. Monday the 3rd August is blown out, Tuesday the 4th lumpy, and Wednesday the 5th hits a massive 12ft SSW swell (2291 energy) – expert-only giant stuff. The hidden gem is Thursday the 6th August morning: glassy, a rippable 6ft SSW groundswell at a 12-second period (1166 energy). That’s clean and powerful for experienced surfers. After that, Friday and Saturday fade into poor wind and messy surf.
So my call: Friday the 31st July morning is the one to circle. Thursday the 6th August morning is a solid backup. Dee Dees is a reef break, exposed to the south, and it can get busy sometimes. Water temp is about average for the time of year.
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.
