The Lowdown
G’day, Rusty here. Look, I’ll level with you – the next 16 days at Octagon House are a long, flat, and frustrating stretch. The only real blip of interest doesn’t show up until the very end, and even that’s a messy one. For the vast majority of this forecast, you’d be better off leaving the board in the shed.
We start off with a real dud. From Friday 17 July right through to the end of the month, the swell is tiny – mostly 0.3 ft to 3 ft, and the combined energy is pathetic, sitting between 4 and 73 (weak). The period is short, often 5 to 7 seconds, so there’s no push. The wind is mostly a cross-onshore breeze from the south or southeast, keeping things choppy and messy. There are a few mornings with a light cross-offshore breeze from the west, which clean things up, but with effectively no swell, it’s just a glassy lake. You’re looking at a solid 14-day gap with nothing worth paddling for.
Then, on Saturday 1 August, we finally see something. The morning brings a bump in swell to 4 ft from the SSE, with a period of 8 seconds and a combined energy of 187 (moderate). It’s a step up, but don’t get too excited. The wind is a fresh 30 km/h cross-onshore from the SSW, so it’s going to be lumpy and difficult. The exposed beach setup here, with a SE optimum swell direction, isn’t really matching the SSE direction we’re getting, so the shape won’t be great. Honestly, with that kind of wind and a beach break, it’s looking more like a kite-surfing day than a paddle-surfing one. The waves will be poor surf conditions across the board.
If you’re desperate for a wave in the first week of August, keep an eye on that 1 August window, but don’t expect much. It’s a long stretch of nothing before that.
Rusty.
