The Lowdown
Alright mate, Rusty here. Let's chew the fat on what's coming. Honestly, it's a grim outlook for Triggs Beach Adelaide. The whole sixteen-day stretch is a bust for any proper waves. The first two weeks are almost totally flat, and when a little bump tries to show, the wind just ruins it.
From the jump on Sunday, August 30th, it's a tiny 0.3ft swell from the SW, barely registering any energy (5). Water temp is average for the season at 58°, but it doesn't matter—the surf is poor. Monday is a complete zero. Tuesday September 1st sees a short-period N windswell push up to 4ft with moderate energy (69), but a fresh 30 km/h cross-shore wind makes it lumpy and messy. That's kite-surfing weather, not for a paddle.
Friday September 4th afternoon gives a pulse up to 5ft with 115 moderate energy, but a strong 45 km/h cross-shore wind from the NNW has it totally blown out. Only the die-hards would be out there. A lull then until Wednesday September 9th morning where a 4ft SW swell with 111 moderate energy arrives, but the cross-onshore wind chops it up. After that, it's back to flat, with a few tiny 0.3ft pulses with long periods (14-16 seconds) that are way too small and weak to matter at this sheltered, inconsistent reef.
So, to put it plainly—there's no day worth chasing. This is one of those blank runs for the area. Forecasts can change though, so don't pack your boards away just yet.
Rusty.
