The Lowdown
Alright folks, Rusty here. We’ve got a bit of a mixed bag coming up for Little Austi and Main Beach. Let’s break it down.
First up, the weekend ahead is a bit of a slow starter. Friday afternoon is looking pretty flat with a tiny 2ft from the SSE and a bit of a side-shore breeze kicking up some chop. But hold on, we’ve got a real chance to get wet on Saturday morning (August 8th). The swell is tiny at 1ft, but the wind is swinging around to the north and going glassy as glass. It’s not going to give you much push, but if you’ve got a longboard or a foamie, you’ll be able to score some clean, tiny peelers all to yourself. The water temp is sitting around 64°, which is pretty much spot on for this time of year, so no surprises there.
The real standout window is going to be Sunday, August 9th. We’ve got a clean pulse of new swell coming in. Sunday morning brings a 4ft swell from the ENE with a period of 10 seconds, and a light NNW cross-offshore breeze. The combined energy is moderate at 232, and it’s going to be clean. Then Sunday afternoon it gets even better. The swell jumps to 5ft from the NE, still with a clean cross-off breeze, and the combined energy climbs to 583. That’s a solid step up. This is shaping up to be the best session of the whole forecast period, so clear your calendar.
Monday (August 10th) is worth a look too, but it’s a bit more of a handful. We get a 7ft NE swell on Monday morning, with a strong offshore wind from the NW at 16 mph. That’s proper offshore, so the waves will be clean and hollow, but with combined energy hitting 719, it’s going to be a powerful. This one is for the experienced crew only. The swell drops a bit in the afternoon to 5ft, but still with that offshore wind, it’ll be fun for the intermediate surfer who’s ready for some punch.
After that, things go quiet again. From Tuesday, August 11th, right through to the middle of the following week, the swell drops off into the 0.7ft to 3ft range, and the wind turns ugly. We’re looking at days of onshore and cross-shore chop, making it a long stretch of poor conditions. There’s a solid 10-day gap of nothing worth paddling out for.
There is a light at the end of the tunnel. Looking way out to Thursday, August 20th, we have a promising morning. It’s a long way off, so don’t book the week off yet, but it’s one to watch. We’ve got a 4ft SSE swell, but this one is a proper groundswell with a 13-second period. The combined energy is 416, meaning it’s got some real grunt behind it. The wind is light and north-northwest, giving us a clean cross-off breeze. This long-period swell will wrap in nicely, but keep in mind at a beach-break setup, it might be a bit wonky. It’s a promising signal for the long range.
So, to sum it up: the pick of the bunch is Sunday, August 9th, especially the afternoon session. Saturday morning is a quiet, glassy option for the loggers. Everything else in the 16-day window is either flat, blown out, or too far out to trust completely.
Rusty.
