The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Little Austi and Main Beach. This is a beach and reef set-up, exposed to the swell, so it can pick up a bit of energy. The water temperature is sitting at 65.3°, which is about a degree and a half warmer than usual for this time of year, so it's a touch on the balmy side.
Right now, and for the rest of this week, it's a bit of a write-off. We're looking at tiny, insignificant waves with poor conditions, so don't bother paddling out until the weekend. There's a real dry spell here.
The first real glimmer of hope comes on Saturday, August 1st. The morning is looking good with a glassy surface and a building SSE swell pushing 4.6ft, period around 9 seconds. The wave energy is moderate (296), and with that light NW wind, it'll be clean. The afternoon sees the swell holding but the wind swings onshore, messing it up a bit. Sunday, August 2nd, is also a solid option for a paddle. The swell is a touch smaller at 3.6ft, but still from the SSE, with a clean, cross-off breeze from the NNW. It's consistent and the wave energy is still moderate (258). This is your best bet for the first week.
Things go pretty quiet again through the start of the next week, with the swell dropping off and the wind turning onshore. We get a bit of a spike around Thursday, August 6th, with the swell kicking up to 5.2ft and then 5.9ft, but the wind is a cross-shore mess, making it choppy and unappealing. The wave energy gets strong (453 to 707), but the quality is poor.
Now, the real standout is a week and a half away, on Saturday, August 8th. This is a big one for experienced surfers only. The morning session is looking epic with an 11.5ft SE groundswell, period of 11 seconds, and a glassy, calm surface. The combined wave energy is very strong (2774). That is a serious amount of power. The swell is long-period, so it will be better at the reef sections than the beach, and it's a solid 11.5ft, so this is definitely not for the faint of heart. The wind is completely dead. This is the pick of the entire forecast. Sunday, August 9th, is still good with a solid 6.9ft swell and clean offshore winds, but that Saturday morning is the absolute winner.
