The Lowdown
Howdy, Rusty here. We’ve got a slow start at Trigg Point – don’t bother for the first couple of days. The wind’s onshore and the surf is messy. A few clean windows pop up later, but you gotta time it right.
Monday 17 August – forget it. Strong onshores, big lumpy surf. Not happening.
Tuesday 18 August through Wednesday 19 August – still marginal. Plenty of swell (wave energy up in the thousands), but wind’s cross-onshore or onshore, keeping it choppy. Water’s a bit colder than normal for the season, about 17°.
Thursday 20 August morning – now we’re talking. Glassy, light wind, 8ft west-southwest groundswell with a 16-second period. That’s long-period, proper groundswell for the point. Wave energy is strong (3639). It’s expert territory at that size, and the crowd’s “often” here, so get there early.
Friday 21 August morning – another glassy morning. 7ft west-southwest swell, 15-second period. Clean as a whistle. Expect company.
Saturday 22 August morning – clean with a light cross-offshore breeze. Swell’s dropped to around 6ft but still a nice long-period groundswell. Fun waves.
Sunday 23 August – wind turns onshore again. Messy. Skip it.
Tuesday 25 August morning – glassy again, but smaller: 5ft southwest swell with a shorter 10-second period. Wave energy is moderate (721). Easy, cruisy session.
Wednesday 26 August morning – glassy, 6ft west-southwest groundswell at 16 seconds. Classy lines for the point. Experts will have a ball.
Thursday 27 August and Friday 28 August mornings – both clean with light offshores. Swell around 5ft then 4ft. Good for all levels.
Now, the big one on the horizon – Saturday 29 August morning – this is a monster. 12ft west swell, 17-second period – that’s very long-period groundswell, wave energy is 6967. The wind is light offshore, so it’ll be clean. Experts only. The point will handle it, but expect long waits between sets. A promising but distant standout.
Tuesday 1 September morning – glassy again, 10ft west-southwest groundswell at 16 seconds. Wave energy is strong (4586). Another big, clean day for experienced surfers.
Best of the bunch? Thursday 20 August morning for a sure thing, and Saturday 29 August morning as a long-range shot. Pick wisely.

Information about the Trigg Point Surf forecast
The above surf forecast table for Trigg Point provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Trigg Point can be found by selecting the local surf guide option on the grey menu. Our Trigg Point 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 Point) 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 Point 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.
