The Lowdown
Alright, Rusty here again, breaking it down in feet and miles per hour.
It’s a patchy run overall for Austinmer Beach. The first few days have tiny waves and mixed winds – a few clean spells but nothing solid. The main issue is the lack of a consistent, quality groundswell with the right wind.
The first real standout is a bit of a big-wave affair. On Wednesday, September 16th, a strong southerly swell hits, pushing 10ft to 11ft. The wave energy is huge (values of 1503 and then 2262), but with a cross-shore wind and that size, this is strictly for experts only. Too big for the average punter.
The better bet is Friday morning, September 18th. A clean 4ft to 4ft southerly swell will be breaking, with a light cross-off breeze from the NNW. It’s a short-period swell (8 seconds), so the waves won’t be perfect, but the energy is moderate at 267, and it will be clean. This is the best window for a fun, manageable surf without the big crowds.
After that, the swell drops to almost nothing from the 19th through the 23rd. There’s a 5ft south swell on the 21st, but it gets messed up by a cross-shore wind. Into the final weekend (September 26th-27th), the swell picks back up to around 5ft to 6ft from the east-southeast, but the wind stays cross or onshore, keeping things choppy and messy. Those days are marginal at best.
So, pick your moment – the small, clean window on Friday the 18th is your best all-rounder, or go big on Wednesday the 16th if you’re a seasoned charger. The rest is quiet.
Rusty.
