The Lowdown
G’day, Rusty here, and I’ve been chewing on the charts for this stretch. It’s a long, quiet slog before we finally see some life. The first week-plus is pretty hopeless—little dribbly swells and messy winds. Save your energy. Then, right at the tail end, a proper pulse shows up.
We’re staring at a big fat gap. The first real surf worth noting doesn’t show until Thursday, the 24th of August. That’s nearly ten days with nothing to recommend. From Thursday the 13th through to Wednesday the 23rd, it’s a total flat spell. A couple of mornings, like Friday the 14th and Sunday the 16th, have glassy conditions, but the swell is pathetic—just 3ft (combined energy of 143) and 3ft (combined energy of 195). Not worth paddling for. The second week stays small—2ft to 3ft, with energy dropping into the 30s and 70s. On Saturday the 22nd and Sunday the 23rd, it’s clean but too small to surf.
Here’s the only real call. The standout is Monday, the 24th of August. Cudmirrah Reef is the spot. We’ve got a crystal-clear morning with light offshore wind from the WNW at 10 km/h (6 mph)—basically glassy. The swell jumps to a solid 5ft from the south, period at 9 seconds, and a combined energy of 459—meaning decent power. The south swell is close enough to the optimum SSE direction for this exposed reef. This is an advanced-level reef that’s “very consistent” when it’s working, so it’ll be good, but 5ft over reef is no joke—experts only. Crowds are just “sometimes,” so you might get a few locals but nothing crazy after such a long flat spell. Water temp is 63°F, which is about 0.7°F above normal, so pretty average for August.
That Monday morning is the clear winner. The afternoon drops back to 4ft (energy 195), still clean but less punch. Tuesday the 25th fades under stronger cross-off wind. Then there’s another pulse brewing for Thursday the 27th—7–7ft from the south (energy cracking 938 and 900), with clean cross-off winds from the west at 20–25 km/h (12–16 mph). That’s serious water moving, but it’s flagged as “marginal surf forecast or questionable tide conditions,” so tides might muck up the reef. It’s promising but less certain this far out.
If you’ve got the skills, lock in the morning of Monday the 24th. The rest is a washout, maybe with a look at Thursday the 27th.
Stay stoked, Rusty.

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.
