The Lowdown
Alright folks, Rusty here. Let’s talk about what’s on the cards for Little Austi and Main Beach over the next couple of weeks.
Right off the bat, we’ve got nothing doing for a good stretch. The first week is a real flat spell, with only tiny, weak waves and poor conditions. You’re looking at a gap of about eight days of mostly unrideable surf, so don’t bother waxing up until we hit the second week.
The real action starts to build on Sunday the 6th of September. We get a pulse of 6ft swell from the southwest, but it’s short-period and the wind is cross-shore, so it’s pretty messy. That’s more of a heads-up than a go-day.
The standout window is Monday the 7th of September. This is the one. Overnight, a solid 7ft swell from the southeast rolls in, with a period of 10 seconds. The energy is strong (836), and we’ve got light, clean offshore winds out of the NNW. This is going to be proper, clean, and punchy. The morning will be the pick with glassy conditions and the water is 64°, which is about average for this time of year. This is for the experienced crew, as it’s over 8ft, so keep the beginners on the beach.
After that peak, the swell backs off but stays rideable through the middle of the week, though the winds turn more cross-onshore, making it choppy. The following weekend into the next week, we see another push of swell, but it’s wind-affected and junky for the most part.
The second best option comes on Monday the 14th of September. The swell is 6ft from the northeast, clean and glassy with a light offshore wind. The energy is very strong at 701. It’s a solid, clean day for the intermediates and up, but the crowds are possible at this spot, so get in early.
So, to wrap it up: this is a slow starter, but the 7th of September is the absolute highlight. The 14th of September is a solid backup. The rest of the run is a mixed bag of small, messy, or onshore conditions.
Rusty.
