The Lowdown

Alright folks, Rusty here. Let’s get stuck into what’s coming up for our local stretch.

We’ve got a bit of a mixed bag over the next couple of weeks. The first real window of opportunity is a quiet one on Wednesday, August 26th into Thursday morning, August 27th. After that, there’s a long, frustrating gap with nothing worth paddling out for until we get to the first week of September. The standout period looks to be around Wednesday, September 2nd, and then again into the second week, but the wind is going to be a constant battle.

The Early Look: Wednesday, August 26th to Thursday, August 27th

The best surf in the immediate forecast is at Nera Rivermouth. On Wednesday afternoon, August 26th, we’ve got a clean 4ft swell rolling in from the SSW. The wave energy is decent at 532, and it’s a cross-off wind from the SE at 15 mph, keeping the face tidy. The water is sitting at 73°, which is pretty normal for this time of year. The swell is a solid 14-second period, so there’s some good push.

Thursday morning, August 27th, is the real pick. The swell drops a touch to 3ft, still from the SSW, but the wind goes glassy—a light ENE breeze at 3 mph. That’s going to be pure, clean lines. The energy is still strong at 413. This is a river and beach setup, so with that long period (15 seconds), it might be a bit critical, but the glassy conditions will make it very user-friendly. Thursday afternoon gets glassy again but with a few rain showers; it’s still surfable, but the morning session is the winner.

The Rough Patch: Friday, August 28th to Tuesday, September 1st

From Friday morning, August 28th, right through to Tuesday, September 1st, it’s a total write-off. The wind is onshore, cross-on, or a messy cross-shore, and the swell quality is just poor. There’s a few days there with barely any wave energy at all. Don’t bother. The forecasts can change, but for now, hide the board.

The Long-Range Promise: Wednesday, September 2nd

Now, here’s where it gets interesting. Wednesday morning, September 2nd, flips the script. We’ve got a 6ft SSW swell with a very strong energy reading of 1294. The wind is a light cross-off from the SE at 6 mph, and the conditions are clean. This is the standout of the whole forecast. The swell is 14 seconds, so it’s got some grunt. It’s a bit chunky at 6ft, so it’s more for the confident intermediate than the absolute beginner. Wednesday afternoon, the wind picks up and messes it up, so make sure you get on it in the morning.

Into the Second Week: Thursday, September 3rd to Tuesday, September 9th

After that Wednesday, the wind gets tricky again. Thursday, September 3rd, is cross-shore and messy. Friday, September 4th, has a big 6ft to 6ft SSW swell with a very long 20-second period and massive energy (2315 to 2523), but the wind is onshore from the SW. That’s a lot of juice with a bumpy face. It’s going to be a beast, but not clean. This setup is more interesting for a kite surfer than a paddle surfer.

Tuesday, September 8th, sees another pulse of strong energy, with a 5ft SSW swell and a 16-second period, building to 8ft by the afternoon. That’s big, expert-only territory. The wind is a moderate cross-shore, so it’s going to be lumpy.

Final Word

The absolute best bet is Thursday morning, August 27th, for the glassy, clean 3ft waves. The long-range winner is Wednesday morning, September 2nd, for the clean 6ft groundswell—just get there early before the wind turns.

Rusty.
