The Lowdown
G’day, Rusty here. Let’s talk about what’s on the way for Trigg Beach over the next couple of weeks.
It’s a bit of a mixed bag to start, but if you can hold out, there’s some real quality waiting. The best window is the last few days of July and the first of August, with clean, solid groundswell.
The week kicks off on Friday, 17 July, with a 6ft WSW swell running at 13 seconds. The energy is moderate (1069). The morning has a light NE cross-off breeze, so it’s clean. Not a classic, but it’s the best session in the early days.
That afternoon the wind swings north and picks up, making a mess. Saturday the 18th is a total loss – an 12ft to 13ft WSW swell with strong onshore winds. Too big and too ugly. Sunday the 19th is still a bit rough with a cross-on breeze, but the 8ft morning swell has some energy (2673). It’s a wait-and-see day.
From Monday the 20th through to Thursday the 23rd, we’ve got smaller surf and improving winds. The pick of that stretch is Thursday afternoon, 23 July. The swell is down to 5ft from the SW at 14 seconds, but the wind is a clean offshore from the east at 12 mph. The water is about average for this time of year. Clean lines, good for an intermediate.
Friday the 24th and Saturday the 25th are small, with 3ft to 4ft swells. Not much happening, but the offshores keep things tidy.
Now, the good stuff. On Sunday the 26th of July, the afternoon session shows a 4ft SW swell with a 15-second period, and the wind is offshore from the ENE at 12 mph. The energy is moderate (780) and the conditions are clean. A nice little groundswell.
The real highlight is Wednesday the 29th of July into Thursday the 30th. Wednesday afternoon is glassy – dead calm, 3 mph from the SSW – with a 4ft WSW swell at 18 seconds. That’s a very long-period groundswell, with strong energy (1530). It’ll be clean and walled up, but the long period means it might be a bit straight at the beach. The reef and point areas at Trigg will be the go. This one’s for the experienced crew.
Thursday the 30th is the absolute gem. The morning has a 5ft WSW swell at 16 seconds, with a light ENE breeze. The energy is strong (2411). The afternoon is even better: 5ft WSW swell, 20-second period, combined energy of 2729, and a light SE cross-off. That’s serious groundswell, glassy conditions, and top-notch quality. A small window of excellence for the experienced.
Friday the 31st drops back a bit, with a 7ft WSW swell but some cross-shore wind. Still worth a look.
A couple of things: Trigg Beach can get crowded, so be prepared. And the first few days are rough, but the wait is worth it. The long-period swells on the 29th and 30th are best handled by experienced surfers, especially at the point.
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.
