The Lowdown
G’day, Rusty here, and I’ve got a look at what’s coming our way for the next couple of weeks. Right now, the surf is a bit of a mixed bag, but there are a couple of sessions that’ll get the heart pumping.
The first few days are marginal, but we’ve got a little window of opportunity on Thursday morning, the 3rd of September. Trigg Beach is the only spot on the radar, and it’s a beach and point setup. The swell is sitting at 8 ft, coming from the WSW, with a long 15-second period that’ll give those waves some real shape. The combined energy is moderate at 2274, and we’ve got a light cross-shore breeze from the north at 6 mph, keeping things reasonably clean. There's a chance of crowds here, as they often pack in, but for a short window, it’s worth a paddle. The water temperature is 64°, which is about a degree colder than usual, so you’ll want a decent spring suit.
Now, the real standout is Tuesday the 8th of September. Trigg comes alive with a solid 10 ft WSW swell, and the period stretches out to 17 seconds – that’s proper groundswell energy. The combined energy is very strong at 5166, and the wind is a clean offshore from the ESE at 16 mph. This is excellent surf for experienced surfers; the waves will have plenty of power, and the offshore wind will keep the faces glassy. It’s a big swell, over 8 ft, so this is for the crew who know what they’re doing. The point break setup here will handle that long period well, giving you some long, racy walls.
The days after that drop off a bit. Saturday the 12th of September morning has a clean 7 ft swell with a light offshore wind, but it’s not as punchy. By the 13th, the swell fades to 4 ft, and the quality drops. There’s a decent gap of flat-ish, marginal conditions from the 14th through the 16th, but look out for Tuesday the 15th of September morning – a huge 10 ft swell with a 19-second period rolls in, but the wind is onshore from the WNW, so it’ll be messy. The combined energy is massive at 6864, but without good wind, it’s a tough call. Still, for the brave, there might be a few bombs.
So, the best bet is clear: Tuesday the 8th of September, first light, at Trigg. Big, clean, and powerful. Get on it.
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 Trigg Beach 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.
