The Lowdown
Alright, Rusty here. Let’s take a look at what’s cookin’ for Cudmirrah Reef over the next couple weeks.
To be straight with you, the first couple of days are a write-off. Thursday the 10th has some size, around 8ft, but that cross-on wind has it choppy and messy – not worth paddling out for. The water temp is 64°, about 2° warmer than usual for September, so it’s a touch on the mild side, but nothing crazy.
Friday the 11th though… that morning session is where it’s at. We’ve got a sweet 5ft south swell with glassy conditions – dead calm, no wind ripples. That’s the kind of clean canvas that makes a reef break like this really shine. The swell energy is moderate (466), and the period is 9 seconds, so it’s a standard short-period south swell, but the complete lack of wind makes it the standout of the whole first week.
After that, the surf fades. From Saturday the 12th right through to Monday the 14th, we’re looking at small stuff, 2ft to 3ft. The wind is offshore or cross-off, so the waves will be clean, but there’s just not enough push to get excited about. You’ll get a few little peelers, but it’s more of a longboard or a funboard kind of morning.
Tuesday the 15th sees a jump back up to 6ft, but it’s a short-period 7-second SSE windswell with cross-on wind and rain – poor conditions and a chop fest. The afternoon gets bigger at 8ft, but the quality is still marginal.
Then we hit another lull from Wednesday the 16th through to Friday the 18th. The swell is small to tiny, mostly under 3ft, and while the wind is light or clean, there’s just no energy (combined energy only 91 on Friday morning). It’s a waiting game.
Now, here’s where it gets interesting. Saturday the 19th of September is the real standout of the whole outlook. The morning brings a solid 8ft south groundswell with a 12-second period, glassy conditions, and combined energy of 1766 – that’s strong wave energy. That is a proper reef-swell setup. This one is for experienced surfers only; that size and power on a reef is no joke for beginners. The afternoon stays clean with a cross-off breeze and still 7ft.
Sunday the 20th keeps the run going with a clean 5ft to 6ft south swell, light offshore winds, and very good conditions. It’s not the size of Saturday, but it’s a far more manageable day for a bigger crowd, and the quality will be high.
Beyond that, the following week looks like a mixed bag. Monday the 21st and Tuesday the 22nd drop in size and the wind turns onshore, so not much to write home about. But keep an eye on Wednesday the 23rd – that’s a 10ft south swell with very strong energy (2767), but the cross-on wind and rain will make it a choppy, blown-out mess. That’s kite-surf territory, not paddle-surfing. It stays big and messy right through to the 25th.
So, if you’re keen, the clear winner is Saturday the 19th morning at Cudmirrah Reef. Glassy, powerful, long-period groundswell. For the everyday surfer, Sunday the 20th is your best bet – still solid, clean, and more forgiving.
Cheers,
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.

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.
