The Lowdown
Alright, Rusty here, breaking down the next couple of weeks for Triggs Beach Adelaide.
I gotta be honest with you, it’s a tough watch. There’s a big lull right from the start. From the 24th of August through to the 7th of September, it’s just no good. Every single report is calling it poor surf conditions. The first few days have combined wave energy down at 3 – that’s barely a ripple. You’re looking at a solid 14-day gap with nothing worth getting wet for.
Water temp is 58°F, which is about what you’d expect for this time of year. Nothing weird there, just a bit chilly.
The only time the ocean shows any life is on Monday the 7th of September. A little swell pushes in at 5 feet from the NNW, but it’s a short period of 5 seconds. The combined energy hits 94 – still weak, but it’s the most we get. Problem is, the wind is howling from the WNW at 18 mph, slamming straight onshore. That’s going to turn any little wave into a messy, blown-out chop. For a kite, maybe, but for a paddle surfboard, it’s a no-go.
The rest of the period is just flat. You get a glassy moment on the 28th of August, but with only 0.3 feet of a 16-second groundswell, it’s like a mirror. That long period stuff is best for points and reefs, but without any height, it’s just a pretty ocean.
So, bottom line: don’t bother. This blank run is pretty normal for the area when it’s this quiet. Forecasts can flip, but right now, there’s no standout session in the whole 16 days. Keep the board in the car just in case, but I wouldn’t hold my breath.
Rusty.
