The Lowdown
Alright, Rusty here again, switching over to feet and miles for the crew that thinks in old-school.
First couple of days at Little Austi and Main Beach? Total flat spell. Thursday and Friday are all tiny, weak east dribble with hardly any energy (5 on Thursday), and the wind is all messy cross-on or onshore. Not a wave worth paddling for.
Then, Saturday the 1st of August brings a pulse. Wind goes glassy in the morning, and we get a clean 5ft swell from the SSE. Moderate energy (396) means it’s got some push. The afternoon stays glassy with 5ft, and the water’s at 66°, a touch warmer than average. This is the best early window—clean, glassy, and the swell direction is spot on. It’s not huge, so intermediates will have a ball.
But the real standout is Sunday morning the 2nd of August: 5ft SSE swell with a 12-second period—proper groundswell—and a clean NNW breeze. The energy hits 852 (moderate to strong). That’s the best wave of the whole run. Get out early because the afternoon gets mangled by a strong cross-shore wind.
After that, it’s downhill. Monday and Tuesday are small and ordinary. Then a long dead stretch from Wednesday the 5th through Saturday the 8th of August—tiny east swells, poor energy, cross-on wind. Nothing.
Next chance comes Sunday the 9th of August. Morning has 2ft from the ESE with a clean cross-off breeze and decent energy (223). Not big, but clean. Then Monday the 10th sees the swell jump to 5ft from the ESE, with strong energy (563 and 609). That’s a solid run, but the wind is moderate, and the report says it’s marginal. Still, if you time it right, there are waves.
The rest of the second week fades to small, clean stuff on the 14th with a glassy afternoon and 2ft, but nothing to write home about.
Your best bet: Sunday morning the 2nd of August at Little Austi and Main Beach. 5ft SSE groundswell, 12-second period, clean offshore wind, strong energy. Nail that session.
Rusty.
