The Lowdown
G’day, Rusty here. Let’s talk about the Trigg Beach outlook. The water’s sitting at 65°, which is just a tick cooler than average for this time of year, so nothing wild.
The first real chance to get wet comes on Monday the 24th of August, but it’s a bit of a letdown. The swell is a solid 6ft out of the WSW at 13 seconds, but the wind is blowing from the WSW at 10 km/h, making it a cross-onshore mess. The combined energy is strong at 1303, but it’s not clean. That afternoon is a bust for quality.
The next few days are a struggle. Tuesday the 25th and Wednesday the 26th are all about strong, choppy winds from the NNW and NW, with swell building to a massive 13ft on Wednesday afternoon. That’s way too big for Trigg, and the wind is onshore, making it a full-on mess. The wave energy is through the roof – 8533 – but it’s not for paddle surfing. This setup looks more interesting for kite surfing than paddle surfing.
Thursday the 27th is still blown out with strong southerly winds, and the swell is still 10ft. Not your day.
Now, here’s where it gets interesting. Friday the 28th of August shows a real shift. The morning brings a clean 6ft swell from the WSW, with a light SSE wind at 15 km/h going cross-offshore. The combined energy is 1220. That’s a solid, clean wave. The afternoon stays clean too, with a 5ft SW swell and a cross-off breeze. This is a solid pick for a fun session.
But the standout of the whole forecast? It’s got to be Saturday the 30th of August morning. The swell is 8ft from the WSW, with a very long period of 17 seconds, and the wind is light from the NE at 10 km/h, making it cross-offshore. The combined energy is a massive 3728. This is excellent surf for experienced surfers. The long period groundswell will produce some real power, and Trigg’s point setup should handle it well. For a true standout, also look at Monday the 31st of August morning, with a 7ft WSW swell at 17 seconds and glassy conditions – a light SW wind at 5 km/h. The energy is 2564, and it’s clean and glassy. Perfect.
Tuesday the 1st of September morning is another gem – 7ft WSW swell, 16 seconds, and glassy conditions with a light SSE wind. That’s a beauty.
After that, things get a bit more ordinary. The swell drops off a little, and the wind starts to play up again. Saturday the 5th of September morning has a 8ft WSW swell at 15 seconds with calm, glassy winds – another excellent window for experienced surfers.
The final week of the forecast sees a return to strong, messy winds, with onshore and cross-shore gusts pushing 25 to 31 mph. The swell is still there, around 7ft, but it’s blown out and not worth it for paddle surfing.
So, the best on offer is Saturday the 30th of August morning and Monday the 31st of August morning. Both have solid, long-period groundswell, clean winds, and good energy. The crowds can be an issue at Trigg, so keep that in mind for the standouts.
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.
