The Lowdown

Alright surfers, Rusty here. Let's look at what's on the cards for Little Austi and Main Beach for the next couple of weeks.

It's a slow start. The early part of the forecast is a mixed bag for Little Austi and Main Beach, a beach and reef break that's fairly consistent. Water temp is around 64°F, a little warmer than average for this time of year, so you might get away with a thinner wetsuit.

Tuesday morning the 25th of August is your first chance. The swell is a mix from the NE at 4.6ft, but the period is a short 7 seconds—wind swell—so it'll be a bit fat. The combined energy is moderate at 291, but the wind is a light NNW cross-off, keeping the surface clean. Not a standout, but you could grab a few waist-high runners. The afternoon sees some rain.

Wednesday the 26th brings a strong SSW wind at 12 mph that blows straight across the face, making a mess of the 3.3ft NE swell. A big no from me.

Thursday the 27th the swell drops to 2.3ft, but don't ignore it. The morning goes glassy with an ENE breeze of 3 mph and only 64 combined energy. It's small, but if you've got a longboard, the morning glass-off is your window for some tiny, soulful peelers.

Now, here is the one true standout: Friday the 28th. The morning brings a clean 5.2ft swell from the SSE with a long period of 11 seconds (combined energy of 607!) and a light SW cross breeze. That's proper groundswell energy. The wind will have the faces lined up. This is the pick of the week for the intermediate surfer—it has push and shape, so get out there for a dawn patrol. The afternoon gets choppy as the breeze swings onshore, so make it a morning session.

Saturday the 29th morning is glassy again, with the swell fading to 3.3ft from the SSE. With 254 combined energy and zero wind, it's going to be smooth, but you'll be hunting for the better sets. A good backup for the longboard.

After that, the outlook goes flat and poor. From Sunday the 30th of August into the second week, the swell drops to a dribble (around 1ft) and the winds are mostly messy or cross-off. The energy values are mostly below 35, which is very weak. There's a brief kick on Tuesday the 1st of September afternoon with a short-period 4.3ft NE swell at 5 seconds (119 energy), but that windswell is too short and the wind is bumpy. Don't bother. The window from the 30th of August through to the 9th of September is a long, flat spell for paddle surfing—the setup looks much more interesting for kite surfing on most of those days. Keep an eye on it, but forecasts can change.

It's not all bad news. We have a proper window on Friday the 28th. Don't miss it.
