The Lowdown
Alright folks, Rusty here. Let's have a look at what Trigg Beach has got cookin' for us over the next couple of weeks.
First up, we've got a solid run of southerly winds. The water temp is sitting at about 64°F, which is pretty much what you'd expect for this time of year, nothing unusual there.
Alright, so we kick things off on Sunday the 6th of September. It's a bit of a slow start. The swell is a chunky 8ft out of the WSW, but that wind is a stiff 30 mph from the SE. It's not a direct onshore, but it's not clean either. The energy is massive, but the conditions are just marginal. I'd be letting that one go.
Now, Monday the 7th is where it gets interesting. The morning is the clear winner of the whole forecast period. We've got a 8ft WSW swell, but the wind has dropped to a gentle 9 mph from the SE, keeping it cross-off and clean. The period is a solid 16 seconds, so there's some proper groundswell power in the water, and the energy reading is massive. This is top-notch, experienced surfer territory. The afternoon is still decent but the wind picks up to 15 mph, so the morning window is the one.
Tuesday the 8th is similar, but the wind is a bit stronger at 15 mph from the ESE. The swell hangs in at 8ft with a 16-second period, and energy is still huge. It's clean, but that wind is getting a bit sporty. Again, a solid option for those who know what they're doing.
Wednesday the 9th is another standout. The morning is a bit fresh with a 18 mph ENE wind, but it's offshore, which is a huge plus for a beach-and-point set-up like Trigg. The swell is a clean 7ft with a 16-second period. The afternoon gets even better with a lighter 12 mph east wind and the same quality swell. This is a real treat, clean and powerful.
Thursday the 10th sees the swell start to back off. It's a 5ft in the morning and dropping to 4ft by the afternoon. The wind is a light cross-off, so it's clean, but the energy is dropping off. Not a write-off, but not the main event.
Friday the 11th is a write-off. The wind swings around to the NW, bringing in a cross-on shore that will chop it up. The swell is there, but it's ugly.
Saturday the 12th is even worse with a full onshore W wind and rain showers. Leave the board at home.
Sunday the 13th is still messy. A 8ft swell from the WSW but a cross-on wind from the SW at 9 mph. It's going to be lumpy and choppy. Not one to get excited about.
Monday the 14th has a glass-off in the morning. The wind drops to zero. The swell is a solid 8ft from the WSW with a 14-second period and strong energy. This is the next real highlight. Dead flat calm, clean, and powerful. A proper session for experienced surfers. The afternoon gets a cross-shore wind that will bring a chop, so the morning is the go.
Tuesday the 15th is similar. Another glassy morning with a light 3 mph S wind. The swell is a bit smaller at 6ft but still has that 14-second period. The energy is moderate. It'll be clean, but smaller than Monday.
From there, the run continues with a lot of marginal conditions. The swell hangs around the 6-7ft mark, but the wind keeps swinging onshore or cross-onshore. Wednesday the 16th, Thursday the 17th, and even into the weekend, it's a lot of average to poor conditions.
There is a bit of a bump on Sunday the 20th of September. The swell pushes back up to 8ft with a 12-second period, and the energy jumps in the afternoon, but the wind is a moderate 12 mph from the west, which is onshore. It's big, but messy.
Then we hit Monday the 21st. This is a big one, but not a good one. The swell is a beastly 12ft from the WSW with a 17-second period, and the energy is absolutely enormous. But the wind is howling at 18 mph from the west with rain. This is for experts only, if anyone is silly enough to go out. For the average punter, this looks more like a kite-surfing day than a paddle session.
So, the pick of the bunch is clear: Monday the 7th of September in the morning and Wednesday the 9th of September in the afternoon. Both have clean, powerful, long-period groundswell and good winds. If you can get out there, that's your window. The glassy mornings on Monday the 14th and Tuesday the 15th are also fantastic, just a little smaller.
There's a big gap of poor to average conditions from Friday the 11th through to the 13th, and then again from the 16th to the 20th. It's a classic Spring pattern, the windows are short but sweet.
Keep your eye on the charts, lads. Things can change.
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.
