The Lowdown
Alright, let’s talk Little Austi and Main Beach. We’re lookin’ at a pretty bleak stretch for paddle surfing over the next couple weeks. Mostly tiny waves, short-period slop, and winds that just won’t cooperate. It’s more of a waiting game than a get-out-there kind of deal.
Water temp’s about 64°, which is normal for this time of year, so no surprises there.
Friday September 11th is a washout. 0.7ft of weak, 15-second ENE groundswell with a combined energy of only 44, and the little wind there is comes onshore in the afternoon. Don’t even bother.
Saturday September 12th and Sunday September 13th are more of the same – tiny 0.7ft waves and messy onshores. Sunday afternoon sees a jump to 4ft at a short, chopped-up 5 seconds from the NE (energy climbs to 97), but it’s paired with a 25 km/h cross-shore wind. That’s ugly. Maybe kite surfers have a look, but for a regular board? No chance.
Monday September 14th morning is your only real glimmer. The NE swell drops to 3ft at a poor 6 seconds (energy 73), but the wind goes glassy from the NNW – dead calm. It’s barely rideable, but it’s the best we got.
Then comes a big dry spell. From Monday afternoon September 14th all the way to Saturday September 19th, everything stays between 0.7ft and 3ft, with mostly onshore or cross-shore winds and weak energy readings (under 100). It’s a dead zone.
Sunday September 20th morning offers a 3ft wave at 6 seconds from the NE (energy 63) with a clean WNW offshore breeze. It’s small and clean, but not enough to get excited.
Monday September 21st and Tuesday September 22nd stay small. 2ft to 2ft, cross-off winds, but still not enough push.
Now, here’s the closest thing we’ve got to a standout, but it’s a long-range promise, not a sure thing. On Wednesday September 23rd morning, we see a jump to 4ft from the south at a short 5 seconds, with an energy reading of 106. The wind is a light onshore from the SSE, so the conditions aren’t perfect, but that’s the most size we’ve had. The afternoon glass-off with 1.0ft isn’t worth it.
The real point of interest is Friday September 25th. The afternoon shows 4ft from the SSE at a groundswell period of 11 seconds, and the energy rockets up to 521 – that’s moderate-to-strong power. The wind is a gentle cross-shore from the NE at 15 km/h. Since this break is a beach and reef, that long-period swell might make it a little straight at the beach, but this is our best chance for a real wave. It’s still marked as marginal, so don’t expect perfect shape.
Saturday September 26th falls right back off into tiny, weak swell with onshores.
So if you’re patient, keep an eye on that Friday September 25th afternoon bump. It’s the only period with real energy in the water. Everything else is slim pickins. And forecasts can change, but right now, it’s a quiet run for Little Austi and Main.
