The Lowdown

Alright, let's get into it. Little Austi and Main Beach is looking mostly flat and average for a good stretch ahead. The water's about average temp-wise for this time of year, so nothing to report there.

First chance of a surf pops up on Friday the 28th in the morning. We're looking at a 5ft swell from the SSE, with an 11-second period. The combined energy is 586 (moderate wave energy). Wind is cross-shore from the SSW at 6 mph, which is alright but not ideal. The swell direction is off the optimum ENE, so it won't be perfect, but it's the first real option on the board.

The real highlight is Saturday the 29th in the morning. It's small, only about 3ft, but the wind is dead calm, glassy - zero. That's huge. The swell is from the SSE with a 10-second period, and the combined energy is 248 (weak to moderate). It will be clean and fun for an intermediate on a longboard or a smaller craft. Don't expect much power, but the conditions will be pristine.

Next best is Tuesday the 1st of September. The morning has a 3ft SSE swell, 11-second period, and offshore wind from the NW at 3 mph. Combined energy is 297 (moderate). That afternoon stays clean with lighter offshore winds from the west. That whole day is a solid, clean session.

After that, it goes dead. From Wednesday the 2nd all the way through to the 6th of September, it's tiny and messy. Barely anything to ride.

Monday the 7th of September morning brings a pulse back - 4ft from the SSE, 9-second period, with a solid offshore NNW wind at 16 mph. Combined energy is 250 (moderate). It'll be clean and punchy. A promising long-range look, but over a week away, so keep tabs on it.

Tuesday the 8th of September afternoon sees a bump to 6ft from the south, but with a short 6-second period. Combined energy is 276 (moderate). That short-period windswell with cross-offshore winds will be more of a kite-surfing show than a clean paddle session.

So, the best bets are Saturday 29th August morning for the glassy conditions, and Tuesday 1st September for that clean offshore. The 7th of September is a watch-and-see.
