The Lowdown
Alright, Rusty here. Let's break down what's in store for Cudmirrah Reef.
We start on Wednesday, August 12th, with a clean 3ft south swell, but it's not got much behind it with a combined energy of 213. The wind is a cross-off, so it's a bit of a tough start. The water is a touch warmer than usual at 63°F, but nothing drastic.
The day to circle is Thursday, August 13th. Head out in the morning. The wind is glassy, dead calm, and the swell is pushing a solid 6ft from the south. The combined energy hits 579, which is a proper injection of power. It's an advanced reef, very consistent, and the direction is spot on. This is the session to be in the water for.
By Thursday afternoon, the wind turns onshore and the swell drops, so don't sleep in.
Friday the 14th is glassy again with a 3ft south swell, but it's pretty ordinary with a weak energy of 161. Saturday the 15th has a bigger 6ft swell, but a strong cross-onshore wind ruins it, turning it into a choppy mess. The pattern of poor conditions hangs around until the 19th, with a few glassy windows but tiny waves.
The next real highlight is Wednesday, August 19th. Another glassy morning with a 5ft swell from the east. The energy is moderate at 286, and with no wind, it'll be clean. It's a good option, but not as powerful as that Thursday the 13th.
After that, we hit a long stretch of small, weak waves until Sunday, August 23rd. That morning is glassy again with a 4ft northeast swell, a period of 10 seconds, and a solid energy of 313. It's a clean, long-period swell for the reef. It's a good call, but crowds are possible, so keep an eye out.
Bottom line: Your absolute best bet is Thursday, August 13th, first light. The 19th and 23rd are good backups, but nothing beats that Thursday morning glass.
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.
