The Lowdown
Alright, folks, Rusty here. Let's have a look at the next couple of weeks, and honestly, it's a bit of a mixed bag. We've got a rough, stormy start, then a lull, but there's a real window of quality lurking in the first part of September if you're willing to wait for it.
The opening act is pretty rough. Saturday the 22nd and Sunday the 23rd are a write-off for a surf. We're looking at strong cross-onshore winds, messy conditions, and a stormy sky. The swell is there, pushing 8ft to 12ft, but it's all over the shop with that wind. Forget it, you'll just be getting worked.
After that mess, the surf drops out. From Monday the 24th through to the end of the month, it's small and pretty uninspiring. There are waves, but they're in the 2ft to 5ft range, and while the wind cleans up a bit, it's mostly cross-shore or cross-off. We're looking at weak to moderate energy (values in the 100-500 range) and the conditions are ordinary. It’s a real patience tester. Tuesday afternoon the 25th will have a light offshore breeze and a clean look, but with only 2ft on offer, you'll be fighting for a ripple. The same goes for the clean mornings at the end of the month, like Sunday the 30th and Monday the 31st – small and crumbly, but at least the wind isn't howling.
Now, hold on to your board, because the first of September is where things get interesting. The morning of Tuesday the 1st is the standout. We've got a proper pulse of swell coming in from the SSW at 7ft with a solid 12-second period. That's pushing strong wave energy (1379) and the wind is blowing offshore from the NNE. This is the kind of conditions that get the heart rate up. It's going to be excellent for experienced surfers, but at 7ft it might be a bit much for beginners.
This is at Suicide Cliffs. The water temp is pretty average for this time of year, so not really a factor, but the surf more than makes up for it.
The rest of that first week of September is still pretty good. Wednesday the 2nd holds some solid size and energy but the wind turns cross-off, so it won't be quite as perfect. We also see a bit more strength in the wind by Thursday and Friday, with a fresh breeze, but it's still offshore and keeping things clean. The swell drops by then, but there are still some rideable, clean waves.
The second week of September looks like it's on the decline again. We're back to small surf with fresh offshore breezes, but nothing that will get you too excited. A few small pulses, but overall it looks like a fade-out.
So there you have it. Saturday the 1st of September is your day. Mark it in the calendar. It's a long way out, so don't book the trip yet, but it's got the most promise. Everything before that is a waiting game.
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 Suicide Cliffs 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.
