The Lowdown
Alright folks, Rusty here, looking at the forecast for Blackies. It’s a bit of a mixed bag, so let's get into it.
We’ve got a long stretch ahead, and honestly, the first week is a bit of a write-off for quality waves. The wait is on for the real action. The early part of the outlook is dominated by onshore and cross-onshore winds, with poor surf conditions flagged consistently. The swell is there, but it’s just not coming together.
The first real standout comes on Sunday, the 6th of September. That morning, the stars align. We’ve got a solid 5 ft swell from the south with a long 14 second period, so there’s plenty of energy in the water (combined energy of 1065). The game-changer is the glassy conditions, with a light 6 mph wind from the northwest. That’s as clean as it gets. Blackies is a beach and point setup, and with that long period south swell, it’ll be lining up nicely. The water is running at 76°F, which is a whopping 9°F warmer than normal for this time of year—very unusual, so you can leave the thick wetsuit at home.
The swell builds through Sunday afternoon, hitting 6 ft, but the wind swings cross-onshore, making it a bit lumpy. The energy is still high (1199), but the morning window is the absolute winner. Monday (7th) still has some size at 6 ft from the SSW, but the wind is a problem again, so it’s not the pick.
After that, the surf drops off. The second week sees smaller waves, mostly around 1 ft to 3 ft, with persistent cross-onshore winds. The energy levels drop back into the low hundreds (168 to 599). The periods are still long, even hitting 20-21 seconds on the 15th and 17th, but with such small waves and poor wind, it’s not going to be worth the paddle. There’s a tiny window on the morning of Wednesday the 16th with a clean 2 ft swell from the SSW, but it’s marginal.
The best advice? Set your alarm for the morning of Sunday, September 6th. That’s the one session to chase. The rest of the 16 days is mostly a waiting game with a few small, less-than-ideal windows.
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 Blackies 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.
