The Lowdown
G’day, Rusty here. Let’s have a chat about what’s coming for Austinmer Beach over the next couple of weeks.
Honestly, the first week is a mixed bag, but there are a couple of clear windows for some clean, smaller waves. A couple of mornings will be worth getting out of bed for.
We’ve got a slow start. Sunday morning (13th September) has a small S swell at 3ft with a 10-second period, and the combined energy is moderate (202). The wind is a light cross-shore NNE at 6 mph, so the surface is a bit ripply – not great. Later in the day the breeze picks up and it gets messy.
Monday morning (14th September) is where it gets interesting. The swell bumps up to 4ft from the NE, but the period is short at 7 seconds – more of a wind swell. The combined energy is moderate (249), and the real winner is the cross-offshore N wind at 6 mph, keeping it clean. It’s a beginner-friendly size, but crowds are possible here on a Monday. Worth a look for a fun, easy paddle.
Tuesday and Wednesday are pretty bleak with onshore junk and small, weak swell, so you can give them a miss.
Now, Wednesday morning (16th September) – this is a big one, but for experts only. The swell jumps to a solid 10ft from the S with a 9-second period, and the combined energy is strong (1328). The wind is cross-shore SSW at 19 mph, creating a lumpy, powerful cross-chop. The swell’s too big for most, and the forecast says it’s likely too big for this break. If you’re a seasoned charger with a big board, maybe, but for everyone else? Stay on the sand. This continues through Thursday with similar energy readings (1737, 1025) – a big, rowdy south swell that’s not really a surfer’s friend here.
Friday morning (18th September) is the real standout. The swell drops back to a friendly 4ft from the S with an 8-second period, moderate combined energy (269), and the wind goes dead calm – glassy. That’s a proper clean session. Light offshore by afternoon, but the morning is the call. Crowds are possible, but with clean conditions like that, it’ll be worth sharing the peak.
Saturday morning (19th September) is another good one. Small swell at 3ft from the ESE, but the period stretches out to 11 seconds, giving it a bit more push. Combined energy is moderate (301). The wind is light cross-offshore SW at 6 mph, keeping it clean. Perfect for a longboard or a fish.
After that, the surf goes pretty quiet with a long gap. From Sunday (20th September) through to the end of the week, it’s mostly tiny, weak, or onshore junk. The combined energy drops to 20–29, which is very weak. Not much to work with.
Saturday morning (26th September) – two weeks out – offers a glimmer. A 5ft NE swell with a short 7-second period, combined energy moderate (377), and clean cross-offshore NNW wind at 6 mph. It’s a hopeful one for the long-range, but the period’s too short to get excited about shape.
Overall, the best surf on offer is Friday morning (18th September) for the glassy clean conditions, and Saturday morning (19th September) for the longer-period, clean small waves. The big south swell mid-week is a no-go for paddle surfing – more of a kite-surfing setup, with strong cross-shore wind and big lumpy chop.
Rusty.
