The Lowdown

G'day, Rusty here. Let's have a look at what's coming up for Trigg Beach.

We've got a decent run of swell over the next couple of weeks, but don't get too excited—the wind is going to be a real pain in the neck for a lot of it. The water temp is sitting at about 65°, which is just a touch cooler than what you'd expect for this time of year, nothing wild.

The strongest and most promising window kicks off on Monday, the 24th of August. First thing in the morning, Trigg is looking clean. We've got a nice 7ft swell rolling in from the WSW, and that's packing some serious energy (combined energy of 1933). The wind is a light cross-off from the SSE, which is going to leave the surface glassy and inviting. This is the standout session of the whole outlook—clean, powerful waves for those with a bit of experience. That afternoon, the wind swings onshore, and things get a bit messy.

Tuesday the 25th and Wednesday the 26th are write-offs for a decent paddle. The wind is howling cross-onshore, and by Wednesday, that swell is building to 10ft and then a massive 13ft. At that size, and with the wind all wrong, it's one to watch from the sand. With the beach and point setup here, you'd be better off with a kite than a paddle on Wednesday—the wind and size just don't suit a fun surf.

We get a bit of a break Thursday and Friday, but the wind stays messy with a strong cross-shore chop. Not worth paddling out for.

Now, here's a good one. Saturday the 29th of August is another proper standout. The morning starts with a clean 3ft swell from the WSW, a long 19-second period groundswell, and a light offshore from the east. This is a long-period swell, which means it's got some real energy and will be better shaped, especially on a point break like Trigg. The long gap between sets will make getting out the back a breeze. Then in the afternoon, it turns glassy with a 5ft SW swell—perfect conditions for an afternoon session. This is the pick for the cleaner, more user-friendly waves.

Sunday the 30th and into the first week of September, the swell stays in the 7ft range, but the wind is almost always cross-onshore or onshore. It's not terrible, but it's not going to be that classic, clean Trigg we all love. There are a lot of marginal sessions here.

Looking further out, into the second week, there's a bit of potential. Monday the 7th of September morning shows a glassy 10ft swell from the WSW, a real big one for experienced crew only, but with no wind and clean conditions, it could be a special session for the brave.

Overall, your best bets are the Monday morning (24th August) for some solid, clean power, and the Saturday (29th August) for a more relaxed, glassy day. The week after that is a bit of a mix of average onshore conditions, so keep an eye on the forecasts.

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.

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.
