The Lowdown
G’day, Rusty here. Let’s have a look what’s on the table for Trigg Beach over the next couple weeks.
Alright, straight up, this isn’t a run of classic, clean all-day sessions. We’ve got some solid pulses of long-period WSW groundswell coming through, but the wind is going to be the story – it’s all over the shop. There are a couple of golden windows where everything lines up, but you’ll need to be picky and on the ball.
The water temp is sitting around 64°, which is about average for this time of year. Nothing unusual there.
First real standout is Wednesday afternoon, September 9. We’ve got some clouds, but a clean 12 mph easterly offshore breeze is blowing straight down the face. That’s going to groom a solid 7 ft groundswell out of the WSW into some nice lines. The period is a meaty 15 seconds – proper groundswell energy, loads of push. The combined energy is reading a very strong 2034, so there’s a lot of water moving. This is excellent, but it’s solid. At 7 ft with that power, this is for experienced surfers only. Beginners should sit this one out.
Next up, Monday morning, September 14 is another cracker. Clear skies and a light 6 mph easterly offshore again. The swell is a touch bigger at 8 ft, still from the WSW, with a 14-second period. Combined energy is cranking at 2227 – strong stuff. Same deal though: this is expert territory. At that size and with the long-period nature of it, it’ll be powerful. It’s a beach and point setup here, so those long-period swells can get a bit straight and dumpy on the beach, but the point should handle it beautifully. Keep an eye on the tide.
Between those two highlights, there’s a stretch of messy days. From Thursday afternoon the 10th through to Sunday the 13th, we’ve got a mix of onshore winds and questionable conditions. The swell stays up, but the wind switches around to the west and WSW, putting a chop on the surface and ruining the shape. Those days are a write-off for a quality session.
Looking further out, Sunday morning, September 20 is worth a mention. We have a lighter 6 mph WNW wind, which is cross-on, but the swell is a clean 8 ft from the WSW with a 12-second period. Combined energy is moderate at 1676. Not a total standout like the first two, but a promising window if the wind holds. It’s still in the “expert” size range though.
After that, the forecast gets a bit messy again through to the end of the period. The swell sticks around but the winds turn strong and cross-shore, making it lumpy. There’s a big spike in size on September 19 – 15 ft from the west – but with a cross-onshore wind and a “poor surf conditions” call, that’s a solid pass. That kind of setup with that much wind and chop is more interesting for a kite surfer than a paddle surfer.
So, to wrap it up: your two best windows are Wednesday afternoon, September 9, and Monday morning, September 14. Both offer clean, powerful, expert-level surf at Trigg. The rest of the period is mostly a battle with the wind. Don’t get too excited about the long-range stuff – it’s promising but very uncertain.
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.
