The Lowdown
Alright, folks, Rusty here with the imperial version.
Let’s be real: Little Austi and Main Beach (beach and reef) is in a bit of a slump for the next 16 days. There’s a gap before anything good shows up. Starting Monday the 24th through Thursday the 28th, it’s mostly small, weak waves or onshore chop. Monday morning has a 0.9m (about 3 ft) NE windswell at 5 seconds, with weak energy (49), and clean but poor waves. The afternoon brings 1.2m (4 ft) but with chop.
Tuesday the 25th morning is the near-term highlight. Swell hits 1.4m (5 ft) from the NE at 7 seconds, energy jumps to 294 (moderate), and the wind is light cross-offshore, so it’s clean. The report says "expect good surf conditions." Afternoon is ruined by rain and a shift in wind. Wednesday and Thursday are all onshore junk.
Friday the 28th morning is dead glassy – no wind – but only 0.7m (2 ft) of weak ENE swell at 8 seconds. Surfable but small. For a log, it might be okay.
The real standout is Saturday the 29th morning. Glassy, light winds from the NNE, with a clean 1.0m (3 ft) at 9 seconds from the SSE. Energy is 205 (moderate). The report says "expect good surf conditions." That’s your best wave window. Crowds are possible, so get out early.
From Sunday the 30th into early September, it all drops off. Most days are below 0.7m (2 ft), with energy in the weak range (down to 21 on Saturday the 5th of September). There’s a small long-period blip on Tuesday morning the 1st of September (0.6m or 2 ft, 11 seconds), but it’s ordinary.
In the second week, Sunday the 6th of September morning gives us moderate offshore wind from the NW at 12 mph (20 km/h), with 0.9m (3 ft) from the NE at 6 seconds. Energy is 69 – weak and small. Clean but tiny.
Water temp on the 24th is 64°, right where you’d expect for late August.
So to break it down: Tuesday the 25th morning is the best near-term call. Saturday the 29th morning is the real standout – the cleanest, funnest surf of the whole stretch. The rest is mostly flat or junky. If you’re desperate, the glassy mornings on Friday the 28th or Sunday the 6th might give you a few little peelers.
Rusty.
