The Lowdown
Alright, Rusty here. Let’s have a look at what Trigg Beach has got cooking for us over the next couple of weeks.
Overall, it’s a mixed bag. We’re looking at a decent run of south-west groundswell coming through, but the wind is going to be the main character for a lot of this period. There’s a bit of a wait for the truly clean windows, but the second week is looking pretty promising if you’ve got some patience.
Starting off this Saturday, the 1st of August, we’ve got a solid 8ft south-west swell rolling in, but it’s a bit underwhelming. The morning has a cross-off breeze so it’s clean, but the wave energy is strong (2560), and the water is running a bit colder than normal for this time of year at 63°. It’s not a total write-off, but it’s not a standout.
Sunday the 2nd is the pick of this first weekend. The morning brings a clean 7ft swell from the west-southwest, and by the afternoon it’s even better. The wind goes light and cross-off, making for clean conditions on a 7ft swell. The swell period is a solid 14 seconds, so there’s real energy there (1390). This is a good, solid session for an intermediate surfer.
Monday the 3rd sees the swell drop to 5ft, and the wind goes messy. Not one to get excited about.
Tuesday the 4th through to the end of the first week is where things get a bit wild. The swell builds, but it’s all onshore or cross-onshore. We’re looking at 8ft to 10ft swells with a very long period, but the wind is junk. The wave energy is massive (over 5000 at times), but for a beach-and-point setup like Trigg, it’s going to be a choppy, blown-out mess. This is more of a kite-surfing show than a paddle-in affair.
The second week is where the real magic lives.
Wednesday, the 12th of August, is a beauty. The morning is glassy, with zero wind, and a 4ft south-west swell with a very long 17-second period. It’s a bit small, but the energy is there (1432), and the conditions will be perfect. This is a great session for getting your longboard or mid-length out and enjoying the clean lines.
Thursday, the 13th of August, is the absolute standout. We’ve got a 8ft to 8ft south-west swell with a very long 18-19 second period. The wind is light and offshore or cross-off, giving you clean, groomed faces. The wave energy is solid (over 3700). This is the session for the experienced crew. The crowd could be an issue, as Trigg can get busy, but for this quality, it’s worth the paddle.
Friday, the 14th, and Saturday, the 15th of August, are also clean and solid. Saturday morning has a 6ft west-southwest swell with a long 18-second period and light cross-off wind. The energy is there (2187), and the conditions will be clean. Another solid option.
Sunday, the 16th of August, the window closes as the wind swings onshore and the swell jumps back up to 8ft. It’s back to choppy, blown-out conditions.
So, if you’re planning a session, make it Thursday, the 13th of August. That’s the one to circle on the calendar.
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.
