The Lowdown
Alright, Rusty here again, giving you the same look in feet and miles.
Little Austi and Main Beach: we’ve got a slow start, but a couple of days that are worth getting excited about.
Right now, through Sunday the 19th into Monday morning, the swell is about all we’ve got. Sunday morning sees a 7ft ENE swell, period around 11 seconds, but the wind is cross-on from the south at 6 mph. Water temp is 65°, which is about normal for this time of year. The combined energy is moderate at 985, but that onshore wind will mess up the surface. Not the day to rush.
Monday the 20th is where it gets good. Swell drops to 6ft from the same ENE direction, but the wind goes clean offshore from the northwest at 6 mph in the morning. That’s glassy, clean. Energy is still solid at 767. This is your best window. Tuesday morning the 21st holds up too, with 5ft ENE swell and offshore NNW wind at 6 mph, energy at 464. Smaller, but clean and fun.
Wednesday morning the 22nd is still surfable, 4ft ENE, but the wind goes cross-off. By Wednesday afternoon we drop to 3ft and the wind goes glassy – clean but small. After that, from Thursday the 23rd all the way through the end of the month, the swell just fades. We’re talking 3ft down to 0.3ft, with mostly cross-off or cross winds. A long dry spell.
Into early August, there’s a pulse on Monday the 3rd with a 4ft SSE swell, but the wind is cross-on at 16 mph and energy is 443. That’s a messy, choppy day. Not worth it.
The standout is Monday the 20th and Tuesday the 21st. Clean offshore winds, decent ENE groundswell, and the break is a beach and reef setup that’s fairly consistent. It’s exposed to the ENE, which is spot on. With 6ft to 5ft swell, it’s fine for most surfers. Crowds are possible on a Monday, but not crazy.
So, if you can, make Monday the 20th your day. The rest of the window is mostly flat or blown out.
Rusty.
