The Lowdown
Rusty here, checkin' in on Little Austi and Main Beach. The outlook is a mixed session over the next couple weeks, with a few fun windows and a lot of waiting.
Right off the bat, Tuesday the 25th of August is the one. Morning brings a 5ft NE swell at 7 seconds, with a combined energy of 328 – moderate – and a north wind sittin' cross-offshore, keepin' it clean. That afternoon holds at 5ft from the same direction, energy jumpin' to 413. Not a big swell, but for this beach and reef setup, it'll offer some rideable waves.
Then it gets grim. Wednesday the 26th turns messy with onshore wind, and that junk lasts a few days. Swell drops tiny, and through the end of August into early September, it's mostly flat, choppy, or blown out. Thursday the 27th morning gives a glassy 2ft from the NE at 8 seconds, but energy is a weak 64. If you're on a longboard and desperate, that clean surface might give you a few bottom turns.
By Tuesday the 1st of September, there's a bit of life. Morning offers a clean 3ft at 6 seconds from the NE under offshore NW wind, energy 96. It's ordinary but clean. The afternoon stays clean with 4ft from the NE at a short 5 seconds – weak, but rideable with low expectations.
Lookin' further out, the weekend of the 5th of September has some potential. Saturday morning shows 4ft from the ENE at 8 seconds, with a gentle NNW cross-off breeze, energy 171. That combo could produce a few decent lines if the tide works. It's the second standout, but it's a week and a half away, so keep an eye on it. The afternoon stays clean, though the wave height drops to 3ft.
The last chance in the window is Wednesday the 9th of September, with a morning of 4ft NE swell at 7 seconds, offshore NW wind, and clean lines. Energy is a modest 115, but with that wind, it might give you one last good session.
Bottom line: the first couple of days are your best bet. After that, expect a flat, blown-out stretch. Forecasts can flip, so stay hopeful.
