The Lowdown
Alright, let’s break this down.
Little Austi and Main Beach has been flat as a pancake for days, and the first week is basically a washout. From today, Sunday July 26th, right through to Saturday August 1st, there’s almost nothing worth paddling out for. Swell heights are mostly under 1 ft, often closer to 0.5 ft or less. Winds are often cross-shore or cross-onshore, and wave energy is weak – readings in the single digits (6, 2, 10) most days. A few mornings go glassy, but there’s zero power behind it.
Then Sunday August 2nd morning changes everything. That’s the real highlight. We’ve got a clean 6 ft SE groundswell with an 11-second period, energy hitting 860 – that’s a moderate, solid push. Wind is light from the NNW, cross-offshore, keeping the surface clean. The swell isn’t a perfect match for the optimum ENE direction, but for an exposed beach and reef set-up, it’ll still produce. With a longer period like that, the reef will hold the shape better than the beach. This is for the intermediate crew – over 5 ft means it’s too much for beginners. Crowds? Little Austi can pack out and this might draw a line.
That afternoon the wind swings NE at 12 mph, turning it cross-shore and lumpy. Energy jumps to 936, but quality goes out the window. Monday August 3rd morning offers a clean 5 ft SE swell with light NNW winds, but energy drops to 405. Decent, not amazing.
By Tuesday August 4th, it’s small again, and stays poor until the next real window on Sunday August 9th. That morning delivers glassy 4 ft SSE swell with a 10-second period and 314 energy. Dead calm, flat ocean – absolutely clean. It’s a nicer session for intermediates, not as powerful or big as the 2nd, but a good day to be out. The tide might play tricks though.
Other than those two mornings, the outlook is mostly small, windy, and not worth the effort. The first week you can leave the board in the car. The second week has just a couple of real shots at glory.
