The Lowdown
G'day, Rusty here.
Alright, let's have a look at what's on the cards for Cudmirrah Reef. It’s a pretty mixed bag over the next few weeks, with a real standout window and some big, angry stuff you'll want to avoid.
The water is sitting around 64°F, which is about 2°F warmer than what you'd normally expect for this time of year. Not a massive anomaly, just a touch of warmth.
We kick things off with a run of small, clean waves. Friday the 11th sees a 5ft south swell with a long 10-second period, but the ENE wind is just a touch cross, making it a bit scratchy. The energy is moderate (440). Saturday and Sunday stay small, with clean conditions on Sunday morning under a light NNE cross-off breeze, but the swell drops to 3ft. It’s surfable, but nothing to write home about.
Monday the 14th and Tuesday the 15th see the swell drop further. Tuesday morning is a ripper for the calm water crew – glassy conditions and a tiny 3ft northeast swell, but the period is a short 7 seconds. The wave energy is weak (102). It's a good time for a beginner to get wet.
Then things get heavy. Wednesday the 16th and Thursday the 17th are a write-off for paddle surfing. A big 12ft south swell hits, but it's hammered by a strong 19 mph cross-onshore wind. The combined energy is massive (2006 and 1852). This is not a surf setup; it's a kite-fuelled whiteout. The same zone sees a 8ft south swell on Thursday, but it’s still messy.
The real standout arrives on Friday the 18th - that's your best bet. A solid 2ft south groundswell with a very long 20-second period rolls in. The wind is a clean, light NNE cross-off breeze. The combined wave energy is strong (580). This is classic Cudmirrah reef conditions – that long period groundswell will focus perfectly on the reef, offering long, walling lines without the chop. It’s an advanced spot, and it’s only for the experienced crew, but it will be absolutely firing. The NW offshore on Saturday the 19th keeps it clean, with a 3ft south swell at 13 seconds. Good energy (315).
After that, the swell fades out into the second week. There's a gap of several days with only very small, poor conditions. The last little pulse is on Monday the 21st with a clean 3ft ENE swell from the NW offshore, but it’s weak (104). Then Wednesday the 23rd sees a building S swell to 8ft, but the cross-onshore wind returns, making it a messy option for experts only.
Overall, don't waste your time on the big stormy swell mid-week. Mark your calendar for Friday the 18th and Saturday the 19th – that’s the true window for some magic at the reef.
Rusty.

Information about the Cudmirrah Reef Surf forecast
The above surf forecast table for Cudmirrah Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Cudmirrah Reef can be found by selecting the local surf guide option on the grey menu. Our Cudmirrah Reef 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 (Cudmirrah Reef) 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 Cudmirrah Reef 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.
