The Lowdown
Little Austi and Main Beach (Little-Austi-and-Main-Beach) – the wait is on. The first week of this run is pretty much a flat, blown-out mess, with nothing worth paddling out for. We’re looking at tiny dribbles and junk wind for days. The only sliver of hope in that first stretch is early Saturday morning the 8th – the wind goes glassy and there’s a tiny 2ft pulse, but it’s super weak with only a 9-second period. It’s surfable, but you’d be working hard for nothing. Honestly, not worth getting wet for.
The energy finally starts to build on Sunday the 9th, with a modest bump of 2ft to 3ft from the ENE and a moderate offshore wind on the Sunday afternoon. The combined swell energy is climbing (146), but it's still pretty average and ordinary. This is more about getting a few grovelly ones than scoring anything memorable.
Then there’s a real gap in quality – Monday the 10th through to Thursday the 13th. The swell stays small (under 3ft) and it's mostly cross-offshore, which keeps things clean-ish, but the waves are just too weak. The direction is all over the shop too, so don’t get too excited.
Now, the standout of the whole period, if you're an experienced surfer, is Friday the 14th. The swell jumps hard – 8ft in the morning and 8ft in the afternoon – from the SSE. The combined energy is pumping (1178), though the period is short at 8-9 seconds, so think of it as a lumpy, powerful windswell rather than a clean groundswell. The winds are onshore, which will chop it up, and with that size, it is expert-only territory. The break is a beach and reef setup, and with 8ft+ waves and crap wind, this is looking more like a kite-surfing day than a paddle-surfing one. It’s big, it's onshore, and it's not going to be pretty.
After that, the size backs off a bit – Saturday the 15th and Sunday the 16th have 5ft to 6ft of cross-onshore slop. It's not good, and the rain on Sunday doesn't help. The energy is moderate (around 400), but the conditions are poor.
Into the second week, the outlook gets messy. Monday the 17th has a decent-sized, long-period swell (5ft at 12 seconds) but it’s completely blown out by a cross-onshore wind. The period is good, but it's hitting this beach-reef setup too straight, so don't expect any real shape. The energy is strong (678), but the wind destroys it.
Tuesday the 18th and Wednesday the 19th have cleaner winds, but the swell drops off (5ft and 4ft) and the period drops to 10 seconds. These are marginal days at best with light cross-onshore wind. You might find a clean one on Tuesday morning if you're desperate, but it’s nothing to plan your week around.
Water temp on the first day you'd want to surf is around 65°, which is a touch warmer than usual for this time of year – nothing crazy, but noticeable.
Overall, the first week is a write-off. The only real spike of size is the 14th, and that’s for experts only and won’t be clean. The second week has some better period swells but can’t get a clear weather window. This is a bleak run – blank stretches are common here when the swell directions don't align. Forecasts can change, so keep an eye out, but right now, I’d be finding something else to do.
