The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Little Austi and Main Beach.
To be straight with you, the next week is a write-off. There's barely a ripple for days. From the 27th of July right through to the 1st of August, we're looking at flat, messy conditions. The swell is tiny, the wind is all over the shop, and the combined energy is weak, barely hitting double digits (14-3). There's a long gap of absolutely nothing worth paddling out for.
The first real sign of life shows up on the morning of Sunday the 2nd of August. We'll see a bump of 4ft from the SSE with a period of 9 seconds. The combined energy jumps to a moderate 211, and with a light offshore from the north, it'll be clean. It's a start, but it's still small and on the average side. The afternoon gets blown out with a stiff NE breeze.
The run of small, ordinary surf continues through the 3rd, 4th, and 5th. The swell hangs around the 2ft to 3ft mark, mostly from the SSE, and the wind is often cross or cross-off. It's surfable, but you won't be telling your mates about it.
The standout window is the weekend of the 8th and 9th of August. The morning of Saturday the 8th is the pick of the whole forecast. We’ve got a solid 8ft swell rolling in from the SSE, with a long period of 12 seconds. The combined energy is strong, hitting 1686. The wind is glassy, coming from the NNW. Now, this is a serious swell. For a beach and reef setup like this, anything over 8ft is expert territory only. It's going to be big, powerful, and with that long period, it'll be a handful, especially for a spot that's exposed. It could be a bit straight for the beach break, but the reefs might handle it. The water temp is about what you'd expect for this time of year, so no surprises there.
The morning of Sunday the 9th is still a good option. The swell has dropped to a more manageable 4ft from the SSE, with a period of 10 seconds. The combined energy is a solid 357, and we've got a light offshore wind from the NNW, so it will be clean. It's a much better size for the intermediate crowd.
After that, the swell fades into the second week. The 10th and 11th of August see small, weaker swells from the NE and ESE with cross-off winds, nothing to get excited about.
So, to sum it up: the first week is a total bust. The weekend of the 8th of August is the time to look at. Saturday morning is the big one for the experts, and Sunday morning is the best bet for the rest of us. Keep an eye on the long-range forecasts, though, as that Saturday window is a couple of weeks out and could change.
