The Lowdown
G’day, this is Rusty. This outlook is all about Trigg Point, and the first part of the run is a bit of a mixed bag – plenty of swell, but the wind’s going to have its say. The real gem is coming mid-week.
The water temp is sitting at roughly 64°F, which is a couple of degrees cooler than you’d normally see this time of year, so don’t be fooled by the sun – it’s nippy.
We start off Tuesday, August 11th with a big, long-period groundswell from the WSW pushing 10ft at 16 seconds. The energy is huge (4820), but a S wind at 12 mph is putting a cross-chop on it – messy and marginal. By the afternoon, it drops to 8ft, but the same cross wind makes it tough.
Wednesday, August 12th morning is where it all clicks. The swell settles to 6ft from the WSW, still a long 14 seconds, and the wind goes glassy – N at 3 mph. That’s pure glass. The water will be smooth, and those lines will be holding up. This is the best session in the near term, but at that size it’s for experienced surfers only. The afternoon gets a light cross-onshore, so get it early.
Thursday, August 13th morning keeps the quality high. 6ft of WSW swell at 16 seconds, with a light cross-offshore NE breeze at 6 mph. Clean. Friday, August 14th is similar – morning and afternoon both look tidy with 7ft / 6ft swell and clean conditions. The energy is solid and well-ordered.
Saturday and Sunday aren’t bad either, with 6ft to 7ft swell and light cross-offshore winds.
Then Monday, August 17th the wheels fall off. The swell jumps to 7ft but an onshore W wind at 12 mph ruins it, and it just gets worse. From Tuesday, August 18th through Wednesday, August 19th, the wind stays onshore and the swell pumps up to a massive 13ft by Wednesday afternoon (energy of 7386). That’s a messy, blown-out storm swell – not for a paddle board. That’s a kite session.
After the storm, Thursday, August 20th morning cleans up with 8ft of WSW swell and a cross-offshore SSE breeze at 9 mph. That’s a good one for big-wave crew. Then Friday, August 21st is the long-range standout. Morning has 8ft swell with a light offshore ENE breeze at 9 mph – clean, offshore, and powerful. The afternoon holds at 7ft with the same offshore wind.
The last few days get dicey again with onshore winds and dropping swell, and the very end of the window on August 26th is just flat and blown out.
So the clear winner is Wednesday, August 12th morning for the glassy, long-period groundswell. The second standout is Friday, August 21st morning – promising, but it’s over a week out, so keep your fingers crossed. Trigg Point can get pretty packed, and with conditions this clean, expect company.
Stay safe out there.
Rusty.

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.
