The Lowdown
G'day, Rusty here. We’ve got a solid 16-day window ahead for Trigg Beach, but it’s a bit of a mixed bag. The surf shows up right from Friday morning, 11th September, with a clean 5ft WSW swell wrapping in. The energy is pumping at 1619 (moderate to strong), and with a light NNE cross-off breeze at 12 mph, it’s looking tidy. The water temp is about average for this time of year, so nothing wild there.
The standout window is Monday morning, 14th September. We’ve got a clean 8ft WSW groundswell with a 14-second period, light offshore easterly breeze at 6 mph, and excellent conditions for experienced surfers. The combined energy is a solid 2392 (moderate-strong). This is the pick of the whole period—big, clean, and powerful. The crowd profile says “often,” so expect company, but it’ll be worth it.
Tuesday morning, 15th September, is another beauty. A 8ft WSW groundswell with 14-second period, gentle ENE offshore breeze at 9 mph, and clean conditions. The energy is 2118 (moderate-strong). This is almost as good as Monday, but the swell is a tad smaller.
After that, the surf drops off a bit. Wednesday morning, 16th September, is marginal at 5ft with a cross-shore breeze and low energy (971). The following days are mostly poor for paddle surfing—strong cross-onshore winds and choppy conditions. The period from Thursday, 17th September, through Friday, 18th September, is a write-off: 4ft to 4ft, bumpy, and gusty winds. The energy drops to 568-591 (weak).
Saturday, 19th September, sees a massive 16ft WNW swell roll in, but it’s too big for this break and onshore. That’s strictly for experts only, and honestly, it’s more of a kite-surfing setup with those strong winds.
The next real highlight is Monday morning, 21st September. A 10ft WSW groundswell with a 15-second period, glassy conditions, and excellent surf for experienced surfers. The energy is 4288 (strong). This is a long-range standout, so keep an eye on it—promising but less certain this far out.
Tuesday morning, 22nd September, also has potential: 8ft WSW groundswell, moderate offshore breeze, and clean. Energy is 2881 (strong). The last few days from Wednesday, 24th September, to Saturday, 26th September, show smaller but clean 4ft to 5ft swells with offshore winds, offering decent waves for intermediate surfers.
Don’t forget, with long-period swells (15-16 seconds), Trigg can get a bit straight at the beach, but the offshore winds will keep it clean. Overall, the best bets are Monday 14th and Tuesday 15th September, with a promising long-range call for Monday 21st September.
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.
