The Lowdown
Alright folks, Rusty here. We've got a long window of calm to work through before anything decent shows its face.
To be straight with you, the first two weeks are pretty grim. The entire stretch from Friday 11th September right through to Thursday 24th September is a write-off for any decent surf. That's a full 13 days of onshore cross-shore winds ruining everything. The swell that does show up is weak, mixed up, and messy, with combined energy readings mostly staying between 58 and 568 (weak to moderate energy), but it's all for nothing with a constant breeze from the ENE hitting the coast. It’s a kiteboarder’s paradise, not a surfer’s.
The one and only standout of this forecast window is Thursday 24th September at JT Flemming . That morning, a light SE wind at 3 mph turns the conditions glassy and clean, and we finally get a cross-offshore flow. Swell will be a solid 6 ft from the ENE, with a period of 9 seconds. The combined energy jumps to a strong 538, showing there's some proper juice in the water. The water temp will be sitting at about 80°, which is basically average for this time of year, nothing out of the ordinary.
The afternoon holds up too with a 6 ft ENE swell, though the period drops to 6 seconds, making it a bit more jumbled and less powerful. The wind swings a bit more easterly but stays cross-offshore, decent enough to keep the surface clean. This is your one and only shot.
Now for the rest: Saturday the 25th, it all falls apart again as the cross-shore wind returns. So make a plan for the 24th. It’s a point break that rarely breaks, so it’s not a bank you can rely on often, but when it does and the wind is right, like on that Thursday, it can be the best wave around. It can get a crowd though, so expect some company if the word gets out.
For the beginners, 6 ft is a bit punchy, but on a point break with clean conditions, it’s doable if you’re feeling brave. The experts will be home.
Bottom line: two weeks of nothing and then a single, promising day on the 24th of September.
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 JT Flemming 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.
