The Lowdown
Alright folks, Rusty here. Let’s get into it. We’ve got a solid run of waves coming up for Trigg Beach, but it’s a bit of a slow burn at first. The water is sitting at 64°F – that’s a touch colder than we’d expect for this time of year, so you might want that extra millimetre of rubber.
The week starts off a little messy. Saturday afternoon (22nd) is a write-off with a lumpy 6ft cross-shore and fresh breeze. Sunday (23rd) is only slightly better – still a bit choppy and cross, with 5ft to 5ft swell. Not worth jumping in for.
Then we hit the first standout. Monday morning (24th) is the one to circle. The wind drops to glassy, absolute perfection, with a clean 7ft swell from the WSW. Combined energy is strong at 1848, and that 14-second period means proper groundswell lines. The commentary says it’s excellent for experienced surfers – and it is. At 7ft, it’s on the bigger side, so not one for the groms, but if you’ve got the skill, this is the best session of the entire first week. Clean, glassy, and all yours.
Tuesday (25th) gets blown out again with a moderate cross-onshore and choppy 5ft to 6ft – skip it. Wednesday (26th) sees a massive 13ft swell with a 19-second period, but the combined energy is a whopping 10264 – that’s a freight train. The file says it’s too big for this break and it’s cross-shore anyway. That’s for experts only, and even then, it’s going to be a washing machine. Thursday (27th) cleans up nicely with cross-offshore winds and 8ft to 10ft groundswell, but the energy is still very high at 4161 to 2878. This is solid, powerful surf for strong paddlers, but the wind is fresh so it’s not the glassy perfection of Monday.
The next clear standout is Saturday afternoon (29th). The wind goes offshore from the East, gentle breeze, with a 6ft WSW swell and a 16-second period. Combined energy is 1629 – moderate-strong – and the report calls it excellent for experienced surfers. That’s a long, clean wall with proper push. The morning is also offshore but smaller at 3ft with a very long period of 18 seconds – that’s a bit too straight for a beach-and-point setup, but the afternoon is the pick.
Sunday (30th) and Monday (31st) see a return to 7ft to 8ft swell with cross and cross-on winds, making it a bit lumpy. Not the best, but still surfable for the experienced.
Now, looking into the second week, we get another promising window. Tuesday morning (1st September) has light offshore wind from the East with a clean 7ft swell from the WSW and a 16-second period. Combined energy is 2080, and it’s rated excellent for experienced surfers. That’s a solid, clean groundswell session. The rest of the week (2nd to 4th September) is mostly cross-shore and a bit messy, with 6ft to 7ft swell – fair to middling.
The real eye-catcher for the second week is Saturday afternoon (5th September). The wind swings offshore from the ESE, moderate breeze, with an 8ft swell from the WSW and a 17-second period. Combined energy is 3530 – strong. The report says excellent for experienced surfers, and it is. That’s a big, clean, powerful groundswell. At 8ft, it’s right on the edge of too big for most, but for the crew who can handle it, this is the best of the second week.
Sunday (6th September) is another monster day – 15ft to 16ft swell with a short period of 10-11 seconds. Combined energy is 4713 to 6021 – very strong. The file says it’s too big for this break. That’s kite-surf territory, not paddle. Don’t even think about it on a shortboard.
So, to wrap it up: the absolute best on offer is Monday morning (24th August) – glassy, clean, 7ft groundswell. If you miss that, the next best is Saturday afternoon (29th August) with offshore wind and clean 6ft, and then Tuesday morning (1st September) and Saturday afternoon (5th September) for the second week. The rest is patchy, but these four sessions are the real deal. Stay safe, and don’t be a hero on the 6th.
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.
