The Lowdown
Alright, let’s get into it. The next couple of days are pretty flat and not worth paddling out for. But hang tight, because things change around the start of August.
The first real chance for a wave comes Saturday morning, 1 August. Little Austi and Main Beach is a beach and reef setup and it’s the spot to look at. Saturday morning we’ve got a 5ft SSE swell, period around 10 seconds – that’s a decent mix of size and energy. The wind is glassy, so the surface will be clean. Combined energy is moderate (525), so there’s enough push. The swell direction (SSE) lines up nicely with the optimum ENE direction for this break. This is for intermediate surfers – 5ft is a bit much for beginners. Crowds are possible here sometimes, so it won’t be empty. Water temperature is about average for this time of year.
Then Sunday morning, 2 August, is the standout of the whole outlook. The swell picks up to 6ft from the SSE, but the period jumps to 14 seconds – that’s a long-period groundswell, bringing real power and shape. Combined energy is strong (1151). Winds are light offshore from the NNW, so the waves will be clean and well-shaped. This is for experienced surfers only – 6ft with that long period can be challenging on a beach-and-reef setup. The long period means the waves will be more organized and better for the reef sections. Sunday afternoon stays good, but the wind shifts a little. After Sunday, the swell drops off and the wind turns onshore, making things messy for a few days.
There’s a gap of poor surf through the middle of the week, with small, choppy conditions. By Thursday 6 August, there’s a short period 5ft to 5ft south swell, but it’s onshore and messy – not worth it. Friday 7 August morning has a glassy 4ft ENE swell, but it’s only 6 seconds, so weak and fat. Combined energy is low (164). Saturday 8 August through Tuesday 11 August mostly shows small, weak waves under 5ft, with only occasional clean windows. The best of the second week is likely Tuesday 11 August morning, with a 4ft NE swell, 8-second period, and offshore NNW wind. Clean, but small. Combined energy is moderate (160). Not a standout, but a salvageable session.
For the rest of the second week, it’s small and inconsistent. Nothing major brewing.
