The Lowdown
G’day, Rusty here. Let’s be straight with you—this is a lean stretch for Little Austi and Main Beach. Most of the next sixteen days look ordinary, with only a couple of windows where you’ll want to be in the water. The water’s sitting right on the money for this time of year at 64°, nothing unusual there.
Tuesday the 1st kicks off with tiny 1ft to 1ft ENE swell, period around 9 to 11 seconds, and a light cross-off breeze. It’s clean but barely enough to bother with—combined energy is weak at 27 to 69. Wednesday the 2nd is similar with 1ft ENE swell and a clean offshore wind, but again, underwhelming. Thursday through to Monday the 7th is a real dog: swell stays below 3ft, winds are all over the shop, and the combined energy never cracks 44. You’d be better off doing something else.
Tuesday the 8th is where it finally gets interesting. The morning serves up 6ft NE swell with a period of 7 seconds, cross-off breeze, and strong combined energy of 684. That’s a solid step up—clean, punchy waves for intermediate crew. By afternoon it drops to 5ft but gets a bit lumpy with a cross breeze; still surfable but not as good as the morning. The 6ft is right on the edge for beginners, but for anyone with a bit of experience, that Tuesday morning is the standout of the whole outlook.
Then it goes flat again from Wednesday the 9th through Friday the 11th—nothing doing, combined energy at zero. Saturday the 12th morning brings a surprise: 6ft SSE swell, period 8 seconds, glassy off a calm wind, and strong energy of 452. That’s another cracker, but it’s a short-lived window—afternoon turns messy with cross breeze. Sunday the 13th has some size at 4ft to 5ft but cross-on wind spoils it.
Monday the 14th morning looks tidy with 4ft ESE swell, period 10 seconds, light cross-off breeze, and moderate energy of 329. Clean enough for a decent session. After that, it fades out through Tuesday and Wednesday with small swell and onshore influences.
Best bet? Tuesday the 8th morning—6ft NE swell, clean cross-off, strong energy. And Saturday the 12th morning—6ft SSE, glassy calm. Everything else is a write-off.
Rusty.
