The Lowdown
G’day, it’s Rusty again. Same story for Little Austi and Main Beach, just in feet and all that.
The forecast is a bit of a bummer. There’s a big blank stretch from now all the way through to Friday, 18th September, with bugger-all worthwhile. The winds are mostly just wrong, and the swell’s tiny.
The one tiny glimmer is on Friday morning, 18th September. We’ve got a clean 2ft swell from the NE, but it’s got a short period of just 6 seconds, so it’s weak and gutless. The wind’s a light offshore, so the surface will be clean. The combined energy is weak at 50. Friday afternoon sees it bump up to 4ft from the NE, still with a short 5 seconds. The wind goes light cross-off, keepin’ the face tidy. The wave energy hits moderate at 110. That afternoon session is the pick, but it’s far from a standout.
With this exposed beach and reef setup, when the wind and swell get messy, it’s better left for the kite crew. Unless you’re desperate for a paddle, give it a miss.
Rusty.
