The Lowdown
G'day, Rusty here. Let's get stuck into what's on the cards for Trigg Beach over the next couple of weeks.
We've got a bit of a mixed bag, but there are some definite windows of clean, solid surf, especially for the more experienced crew. The water's sitting at 63° which is a bit colder than normal for this time of year, so don't forget a spring suit or at least a good rashie.
The first real standout is Tuesday the 1st of September, first thing. We're looking at a clean 6ft swell from the WSW with a long 16-second period, and a light cross-off breeze from the SSE. The combined energy is a solid 1559, and the water's a touch cool. This is excellent, clean surf for experienced surfers, but it's not too crazy for a confident intermediate either. The morning is the go, as the afternoon gets a bit onshore and messy.
The next big moment is Sunday the 6th of September. The morning has a glassy, clean 12ft swell from the WSW with a 13-second period. The combined energy is massive at 3919, and the wind is light and cross-shore. This is a proper swell for experienced surfers only – it's a solid, powerful groundswell that's going to be handling a lot of water. The morning is the pick before the wind turns onshore.
Then, Monday the 7th of September is a magic morning. The wind is dead calm, glassy, and we've got a 10ft swell from the WSW with a very long 17-second period. The energy is huge at 4436. This is a classic, clean, powerful groundswell. It's still a big one, so it's for the experienced crew, but the conditions are absolutely perfect. The long period will make for some really deep, well-shaped waves, especially holding up nicely on the point.
After that, we get a few more good mornings. Tuesday the 8th of September has a clean 8ft swell from the WSW with a 16-second period, and a light offshore from the E. The energy is 3647. Then Wednesday the 9th of September afternoon cleans up nicely with a 7ft swell from the WSW, a 16-second period, and a clean cross-off breeze. The energy jumps to 3533. Then Saturday the 12th of September has a clean morning with a 8ft swell from the WSW, a 13-second period, and a solid offshore breeze from the E. The energy is 2287. And Tuesday the 15th of September has a solid morning with a 8ft swell from the SW, a 15-second period, and a clean offshore from the E. The energy is 2970.
The middle of the second week gets a bit dicey, with strong winds and big, messy conditions. The weekend of the 5th and 6th has some serious wind and huge swell, which is pretty much a write-off for paddling but might be interesting for the kite surfers.
Overall, the best of the best is the Monday the 7th of September morning. That glassy, long-period groundswell is a rare treat. The Tuesday the 1st of September morning is also a cracker for a more manageable size. Get out there if you can.
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.
