The Lowdown
Alright, mate, Rusty here. Let’s have a look at what’s on the menu for Trigg Beach over the next couple of weeks.
We’ve got a solid run of WSW groundswell on the way, but it’s going to be a bit of a mixed bag with the wind. The early part of the week is looking like the best bet for clean, offshore conditions, but the swell is a touch strong for the average punter. The real standout is Tuesday afternoon, September 8th, where we’ve got a clean 8ft swell from the WSW with a 16-second period and a lovely offshore breeze. The water is sitting at 64°, which is a bit colder than normal for this time of year, so you’ll want a decent steamer. The energy is massive too, with a combined energy reading of 3636, so there’s plenty of grunt in the water. This is proper groundswell with a long period, so it’ll be well-shaped and powerful, but it’s getting up there in size and is best left for the experienced crew. It’s a beach and point setup, so that long period should wrap nicely around the point. This one’s a gem.
The next morning, Wednesday September 9th, is also looking good. A bit smaller at 7ft, but still a clean offshore wind from the East at 19 mph, with that same long-period WSW groundswell. The energy is still strong at 2200. Another good session for the competent surfer.
Thursday September 10th sees the swell drop to 5ft in the morning and 5ft in the afternoon. The morning has a fresh offshore wind, keeping it clean, but it’s a bit weaker in energy (1125). The afternoon goes a bit cross-off. It’s still surfable, but not the standout.
Now, things get a bit messy from Friday September 11th onwards. We get a massive 19-second period swell on the Friday, but the wind goes onshore and cross-onshore, making it a bit of a battle. The energy is huge on Friday afternoon at 4299, but the onshore wind will chop it up. Saturday and Sunday are plagued by strong onshore winds, so you’ll be scratching for a clean one. The swell is still solid, but the quality is poor.
Monday September 14th is a bit of a phoenix from the ashes. The morning session has a clean 8ft swell from the WSW with a 14-second period and a light offshore breeze from the ENE. The energy is strong at 2020. It’s another one for the advanced surfer, but the conditions are a lot better. The afternoon gets messy with a cross-shore, so get it early.
The following week, from September 16th onwards, is a bit of a write-off with onshore winds and chop. There’s a few glimpses of hope, like the morning of September 23rd which has an 8ft swell from the WSW with a light cross-shore wind, but it’s a long way off and the consistency is a bit of a gamble. The energy is still solid at 2379, but the wind is just not cooperating.
The best bet for the more average surfer? The Thursday morning September 10th with the 5ft swell and the fresh offshore wind is probably your most manageable clean option. But for the full, raw experience, you’ve got to get out there on Tuesday afternoon September 8th or Wednesday morning September 9th. That’s the real deal.
Rusty.

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.
