The Lowdown
Alright, grab your wettie and let’s have a look at what Trigg Beach has in store for us over the next couple of weeks.
First up, Trigg Beach is a beach and point setup, fairly exposed to the swell, and it likes a good WSW swell direction. The water’s sitting at 63°, which is a bit colder than normal for this time of year – about 2° off the average, so you’ll feel that extra chill.
Now, we’re starting off with a bit of a slow burn. The first few days, from Sunday afternoon the 30th right through to the start of September, are pretty average. We’ve got solid swell in the 7 ft to 8 ft range, and that’s coming from the WSW with a long 17-second period – that’s proper groundswell energy, but the wind is letting us down. It’s mostly cross-on or onshore, and the wave comment is calling it marginal at best. The combined energy is high, three to four-digit values, but with those winds, it’s just not clean. Monday the 31st and Tuesday the 1st are looking pretty grim, with scores reflecting that.
Wednesday the 2nd and Thursday the 3rd don’t get much better. Swell drops a touch, still 7 ft, but the wind stays messy. Thursday morning has a moderate cross-onshore breeze and the wave comment says poor surf conditions. This is a bit of a write-off for a paddle.
Then we hit a real rough patch. Friday the 4th through Sunday the 6th of September, the swell pumps up hard – 10 ft to 12 ft – but the wind is howling. Friday afternoon has an 12 ft swell with 15 seconds of period, but the wind is cross-on and the combined energy is massive (4963). The wave comment even says the swell is predicted to be too big for this break. That’s expert-only territory, and with the wind, it’s more of a kite-surfing show than a paddle session. Saturday and Sunday are the same story: big, powerful, and blown out.
Now, here’s where things get interesting. Monday the 7th of September is a true standout. We’ve got a 10 ft WSW swell with a very long 17-second period, and the wind goes glassy – a slight air from the SW. The combined energy is massive (5089). This is excellent surf for experienced surfers only. That big, long-period groundswell will be breaking a bit straight at a beach break, but Trigg’s point setup might just handle it. The wave comment says excellent conditions for experienced surfers. This is the pick of the forecast, no question. Expect it to be clean, powerful, and for the crew that can handle it.
Tuesday the 8th of September is another beauty. Still a 10 ft swell from the WSW with a 17-second period, and the wind swings to a light NE cross-off. That’s clean conditions. The combined energy is still huge (5046). Again, this is for experienced surfers, but it’s a serious session.
Wednesday the 9th of September morning is also good. The swell drops a touch to 8 ft with a 16-second period, and we get a NNE cross-off breeze. The wave comment says clean and excellent for experienced surfers. The combined energy is still very strong (3929). Thursday the 10th stays big at 10 ft, but the wind goes cross-on, so it’s not as clean.
After that, things drop off again. Friday the 11th and Saturday the 12th see the swell back down to 6 ft to 6 ft, but the wind is onshore or cross-on, so it’s messy. Saturday afternoon the 12th has a huge 12 ft swell, but it’s predicted to be too big for the break again. Sunday the 13th is also too big and windy. Monday the 14th has strong winds and poor conditions.
So, to wrap it up: the first week is a write-off. The real action kicks off on Monday the 7th of September and runs through Wednesday the 9th. That’s your window. If you’re an experienced surfer and you can wait, that glassy Monday morning is the one. If not, it’s a lot of waiting around for blown-out or too-big surf.
Stay keen, and keep an eye on the charts.

Information about the Trigg Beach Surf forecast
The above surf forecast table for Trigg Beach provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trigg Beach can be found by selecting the local surf guide option on the grey menu. Our Trigg Beach surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Trigg Beach) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. 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.
