The Lowdown
Alright, Rusty here again. Let’s break down the next couple of weeks at Little Austi and Main Beach. It’s a quiet start, so don’t rush in.
Little Austi and Main Beach is a beach and reef break that’s fairly consistent. The water’s running about 64°, which is pretty standard for this time of year.
Saturday the 8th is flat and forgettable. 1ft SSE swell, weak energy (50), and the wind turns ugly in the afternoon. Leave the board at home.
Sunday the 9th shows some life. Morning brings 3ft ENE swell with a 10-second period, moderate energy (138), and a clean cross-offshore breeze. The afternoon pushes to 4ft, still clean, with energy hitting 298. It’s surfable but not a standout.
Monday the 10th is the real deal. A 7ft NE swell rolls in with a 9-second period, strong energy at 727, and offshore winds from the NNW. It’s too much for beginners, but for intermediates, this is the session to chase. The afternoon holds at 6ft with fresh offshore winds. This is the clear highlight of the outlook.
Tuesday the 11th drops to 3ft, clean but weak. Wednesday the 12th has a tiny 2ft offshore morning, but the energy is barely there (62). From Thursday the 13th through Saturday the 15th, it’s all 1ft to 1ft junk with cross-on or onshore winds. Poor conditions.
Sunday the 16th sees a brief spike to 3ft SSE in the afternoon, but the wind is onshore and the quality is poor.
Monday the 17th offers a glassy 3ft SSE morning (146 energy), but it’s very ordinary. After that, it’s a long stretch of tiny, onshore waves right through to the 23rd.
Even a 5ft SSE pulse on the 22nd is ruined by onshore winds and a short 6-second period. The energy is there (203), but the waves are a mess.
If you’re into kite surfing, those windier, bigger afternoons might be worth a look. But for paddling, Monday the 10th is your only real call. Don’t miss it.
Rusty.
