The Lowdown
Alright, Rusty here. Let’s talk about what’s ahead.
First up, there’s a bit of a wait for anything decent. The next few days are looking rough with onshore wind and choppy conditions. The real action kicks off on Monday the 7th of September, when things start to clean up.
The standout of the whole run is Monday morning, September 7th, at Trigg Beach. We’ve got a solid 8ft swell from the WSW, with a very long period of 16 seconds – that’s proper groundswell. The wind is light and offshore from the ESE at 9 mph, keeping it clean. The combined wave energy is strong (3726), and the conditions are set for experienced surfers. The water temp is about average for this time of year, so don’t expect any surprises there.
The good news keeps rolling into Tuesday the 8th. Tuesday afternoon at Trigg is another top pick: 8ft from the WSW, with a 16-second period, clean offshore wind from the ESE at 12 mph, and very strong energy (3834). This is clean, powerful surf for those who know what they’re doing.
Into the second week, Wednesday the 9th looks promising too. Wednesday afternoon has 7ft from the WSW, 15-second period, and clean offshore ENE breeze at 12 mph – solid but a little less energy (2265). By the weekend of the 12th and 13th, the wind turns onshore and the quality drops off hard, with rain and messy conditions.
Then, a proper second wind: Monday the 14th of September. Monday afternoon delivers clean 8ft from the WSW, 14-second period, with a light offshore breeze from the ESE at 6 mph. The energy is moderate (2202), but the conditions are excellent for experienced surfers. That’s your last true gem.
After that, the window closes fast. The 16th and 17th bring strong winds and poor surf, and by the 19th and 20th the swell is huge – up to 15ft – but the wind is cross-onshore, making it messy. On Sunday the 20th of September, there’s a fleeting moment of glassy conditions with a 13ft WSW swell, but it’s too big for most and the forecast says it’s too big for the break. Definitely not one for beginners.
Bottom line: aim for the 7th to the 9th, and the 14th. Those are your windows. The rest of the run is either waiting, blown out, or too big for comfort.

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.
