The Lowdown

Alright, grab a coffee and let’s see what’s cookin’ for Trigg. We’ve got a proper run of solid groundswell coming our way, so pay attention because there’s some good ones in the mix, but also a real monster to dodge later on.

The water temp is sitting pretty average for this time of year, nothing wild to report there. The opening Tuesday (11th August) is a write-off for most. We’re getting a thumping 12 ft WSW groundswell with a long 16-second period, but it’s just too much for Trigg. The wave energy is colossal (5662), but we’re talking expert-only levels of power and size. The wind is cross though, so if you had a craft that could handle it, maybe a look in the morning, otherwise, give it a miss.

Now Wednesday the 12th, that’s the one to circle. Morning glass-off with a northerly breeze that’s barely a whisper. The swell drops back to a still-chunky 7 ft from the SW, but that’s a groundswell with a solid 15-second period. The break cleans right up with that offshore vibe. This is for experienced crew only because it’s still well over the beginner mark, but those clean faces and long lines are going to be a treat. The afternoon gets a bit bumpy from a cross-onshore, so bag that morning session.

Thursday the 13th keeps the goods coming. Morning again is clean with a cross-off NE wind. Same size, 7 ft SW with a long period of 16 seconds. The energy is strong at 2299. More great surf for the confident amongst you. Friday the 14th looks mint too, with another glassy window in the afternoon.

We cruise through the weekend with clean but more modest 6-7 ft swell, and the NE seabreeze gets a bit of puff on the Saturday and Sunday mornings, but the arvos clean right up. Good conditions for the crew who can handle a bit of size.

But then we hit Monday the 17th, and the wheels fall off. Onshore gales from the WSW churn things right up. That 8 ft groundswell is still there, but it’s a mess. A total skip day.

The following Tuesday the 18th cleans up a bit, but it’s back to 10 ft from the WSW. Still too big and with less than ideal winds, it’s hard to get excited. Then Wednesday the 19th and Thursday the 20th are just a no-go zone with a massive 13-16 ft west swell and howling onshore winds. The wave energy readings are insane (up to 12492), but it’s a washing machine. If you’re into kitesurfing, this might be your window with that huge swell, but for a paddle board, it's a hard pass.

The final weekend (22nd-23rd) is a messy one with strong cross-shore winds, so nothing really comes together until we look further ahead. Monday the 24th offers a glimmer of smaller 5 ft surf, but it's messy. The real potential is Wednesday the 26th. A solid 7 ft WSW groundswell with a long 17-second period and a clean cross-off. That’s nearly two weeks out, so take it with a grain of salt, but it could be a proper little gem if things lock in.

Overall, don’t sleep on Wednesday or Thursday this week for bigger, cleaner waves. The rest of the run is a mixed bag with a serious slab of junk in the middle.

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.
