The Lowdown
G’day, Rusty here, looking at what’s coming up for Trigg Beach. This is a beach and point setup, pretty exposed to the swell, so it can get some good energy when things line up. The water temp is sitting around 64°, which is about average for this time of year – nothing unusual there.
We’ve got a decent run of swell coming through, but the wind is going to be the main character in this story for the first week. It kicks off Monday the 7th with a solid 8ft WSW groundswell, period a long 16 seconds, and light cross-off winds. The ocean’s got some serious energy behind it – combined energy of 3726 (moderate to strong) – and the conditions are clean, but with that size and long period, it’s really only for the experienced crew. That’s the pick of the first few days. Monday afternoon the wind picks up to 15 mph, and from Tuesday the 8th through Thursday the 10th, the breeze is stronger, keeping things a bit messy even though the swell stays around 8ft to 4ft. The energy drops off through Thursday, and by Friday the 11th, the wind swings cross-onshore, making it choppy and poor. The stand-out is definitely Monday morning – clean, powerful, and for the skilled only.
The weekend from the 12th gets blown out with onshore winds and a big 10ft swell on Saturday, really poor conditions. Sunday the 13th is still onshore. Not worth paddling out.
Now, here’s where it gets interesting. Monday the 14th morning, we get a clean up with light ENE cross-off winds and a 8ft WSW swell, period 14 seconds, energy at 1991 – that’s a good session for experienced surfers. Then Tuesday the 15th morning is a beauty: glassy conditions, 7ft WSW swell, 14-second period, energy 1623, and the wind is almost nothing. That’s a standout – clean, solid, and manageable. The rest of that week dips in quality, with Wednesday the 16th turning choppy and the swell dropping.
The second week gets a bit wild. Thursday the 17th is a write-off with strong cross-onshore winds and a lumpy 10ft swell. Friday the 18th has a massive 13ft WSW swell, period 16 seconds, but the wind is onshore and the break is simply too big for Trigg Beach – that’s only for the very keen experts if they can handle it. Saturday the 19th and Sunday the 20th improve a little with lighter winds, but the swell is still big, around 10ft, and the conditions are mixed. Monday the 21st morning sees another 13ft monster with a 19-second period, energy through the roof at 10735 (very strong), but again, it’s too big for this spot. Tuesday the 22nd is still large at 10ft and choppy.
Best on offer? Lock in Monday the 14th morning and Tuesday the 15th morning. Those are the cleanest, most surfable windows with proper swell and good winds. The first week’s Monday morning the 7th is also a solid session for the experienced.
Stay safe out there. 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.
