The Lowdown
G’day, Rusty here. Let’s not sugarcoat it – the first week at Trigg Beach is a tough watch. The swell is building, but the wind is all over the place, mostly cross-onshore making it a choppy mess. You’ve gotta wait over a week for the real deal. The standout is a clean, glassy morning just under two weeks out.
We start on Tuesday, August 25th. The morning is clear, but a 25 km/h NNW cross-on wind is messing up a 1.4m, 12-second WSW swell. The energy is weak at 845 – total garbage for a board. Afternoon is the same story, a 1.6m swell with the same junk wind.
Wednesday, August 26th, things get big. The swell hits 3.0m in the morning with a 16-second period from the WSW, and the combined energy jumps to 6197. It’s powerful but choppy. By the afternoon, it’s 3.5m, 18 seconds, and a massive 7716 energy reading. The wind is a light SW cross-on, but at over 2.5m, this is big-wave territory for experts only. That long-period groundswell will be breaking straight and heavy on the banks.
Thursday, August 27th, the swell drops to 3.0m, but a fresh 30 km/h southerly cross-off cleans it up. Energy is still 4214. It’s clean, but still over 2.5m. The afternoon eases to 2.5m, clean, but still a big wave.
Friday, August 28th, the swell eases to 1.9m in the morning with a clean cross-off from the SSE. By the afternoon, it’s back to 1.4m and looking poor.
Saturday, August 29th, is a weird one. Morning has a tiny 0.9m, 19-second swell – a long period on a small wave won’t do much. The afternoon lifts to 1.7m, still 19 seconds, with clean ESE wind and an energy of 1920, but it’s marginal.
Sunday, August 30th, is our first real ray of light. The morning has a 2.2m, 16-second WSW swell with a light NE breeze making it glassy and clean. Energy is 2480. This is the first “excellent” call of the forecast. It’s over 1.5m, so not for beginners, but for the rest of us, this is the one to paddle out for in the first week.
The week slugs along. Monday, August 31st, is a write-off with cross-on wind. Tuesday, September 1st, has a 2.1m swell with light offshore wind, but it’s only scoring as marginal.
Now, here’s your real target. Thursday, September 3rd, morning session: a 2.5m, 15-second WSW swell with *glass* conditions – absolutely no wind. Combined energy is 2771, and it’s rated excellent for experienced surfers. This is the absolute standout of the whole 16-day window. Mark it down.
From Friday, September 4th, through Sunday, September 6th, we get clean offshore winds from the ESE and ENE, with a steady 1.7m to 2.1m swell. Good, clean, and consistent sessions.
Monday, September 7th, the morning is a clean 2.1m, 14-second swell with offshore wind. The afternoon turns into a 1.5m, 20-second groundswell with 3038 energy – ultra-long period, so think of the points and reefs. Still, it’s clean and excellent.
Tuesday, September 8th, delivers the other big highlight: 2.5m, 16-second swell all day with clean offshore ENE wind at 20 km/h. Energy over 3000. Big, clean, and excellent for experienced hands.
After that, Wednesday, September 9th, gets messy with a fresh cross-off in the morning and a choppy cross-on in the afternoon. The good run is over.
Bottom line: suffer through the first week, get in the water on Sunday, August 30th, and don’t miss Thursday, September 3rd, and Tuesday, September 8th. Those are the gems.
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.
